The 63 Language Models With Examples and Actionables for SEOs. 

We are presenting these models in somewhat of a prioritized manner rather than alphabetically. Note the word, “somewhat,” as endless arguments between SEOs might emerge between the actual order of this list. This is simply a semi-prioritized list based on how we are seeing things currently.

Each model follows the following pattern:

  • Name of the Model. 
  • Super short definition and example of the model at work
  • A longer, more technical description of the model. 
  • Examples of how a search engine might use this model to help determine ranking and query matching. 
  • An idea kickstarter. These are NOT concrete do these items. These are hypothetical: IF this model were ever to be used, then here are some ideas of practical steps you could take to improve your page’s/site’s presentation for that particular model to reward your site in ranking. They should spawn you onward in your own thinking.

Conceptual Semantic Lexical Relations

This looks at how concepts, word meanings, and vocabulary connect. For example, it relates the concept of “transportation” to words like “car” and “train”.

Search engines rely heavily on understanding the conceptual, semantic, and lexical relationships within web pages to properly interpret their content. Analyzing these different dimensions of meaning can reveal the key topics, entities, and themes that characterize a page. For example, mapping out lexical relations between words can uncover synonyms and related terms that indicate core concepts. Identifying semantic relations between entities mentioned on a page provides insight into what real-world objects and events the content describes. Modeling conceptual relations gives a broader view of the main ideas and abstractions that underly the text.

Practical examples:

  • Recognizing synonyms and hypernyms during lexical analysis could help aggregate evidence for pages about a topic, even if they don’t share exact keyword matches.
  • Identifying meronym semantic relationships could boost pages that comprehensively cover parts of a larger concept.
  • Modeling conceptual relations may reveal pages with more abstract, high-level relevance to a topic instead of just literal word matches. 

Three Potential Actionable SEO Ideas

  • Expand page wording with synonyms and hypernyms of key concepts to improve topical keyword density.
  • Structure content using lexical chaining techniques to tie together semantically related terms.
  • Optimize site architecture so pages focused on narrower concepts link into hubs about broader topics.

Cross Pos Relations

This analyzes how different parts of speech, like nouns and verbs, link together in sentences. For example, it looks at how nouns connect to verbs.

Analyzing the relationships between parts of speech used on a webpage can reveal important clues about its information content. Research shows distinctive patterns of nouns, verbs, adjectives and other grammatical classes within text of differing subject matter, style and sentiment. Leveraging these cross-part-of-speech relationships allows search engines to categorize and compare pages based on their structural composition. For instance, some topical areas feature heavier use of nouns versus verb constructions. Pages with a higher incidence of adjectives may suggest more subjective or promotional content. Detecting the frequency and co-occurrence of POS tags provides useful input to better understand a document’s focus and quality.

Practical examples:

  • Flagging pages with an inflated adjective-to-noun ratio could help filter out low-value promotional content.
  • Indexing pages based on their distinctive POS tag patterns can aid topical clustering and classification.
  • Identifying pages with more past vs present verb constructions may influence assessments of freshness.

Three Potential Actionable SEO Ideas

  • Balance page structure for a mix of nouns, verbs, and descriptive phrases suited to the content type.
  • Avoid excessive use of qualifiers and intensifiers which may flag subjective promotional content.
  • Review site content ensuring consistent verb tenses between product/service pages and related blog posts.

Dependency Parsing

This figures out how each word in a sentence depends on or relates to other words. For example, it links the noun “dog” to the verb “barked”.

Analyzing the syntactic dependency relationships in the sentences of a webpage provides clues about its information content. Recursively identifying which words depend on or modify other words reveals the underlying predicate-argument structure of the text. This allows search engines to glean key semantic aspects, like subjects, objects, and actions described by a document. It also aids in resolving modifiers and qualifiers so that core factual statements can be extracted from the text. Overall, dependency parsing helps search engines move beyond just matching keywords to understanding pages’ meaning and propositional content so that results can better match user intent.

Practical examples:

  • Identifying pages with higher densities of object-action-subject dependencies may suggest more informational content.
  • Parsing adjective and adverb modifiers may help determine the sentiment expressed toward key topics.
  • Linking pronouns and references to their dependencies can unwind long, complex sentences into more meaningful semantic relationships.

Three Potential Actionable SEO Ideas

  • Craft page content with clear subjects, objects, and descriptive adjectives around key topics to aid comprehension.
  • Use pronoun references to link back to subjects unambiguously for improved readability flow.
  • Provide examples of topics tied together in logical sequences with transitional phrases to demonstrate relationships.

Semantics Relations Labeling

This involves tagging how words and concepts relate to each other with role labels. For example, it could link “Steve Jobs” to “Apple” with a “founded” label.

Annotating semantic relationships between entities mentioned in a webpage’s content can augment search engines’ understanding of its topics and meaning. Techniques like semantic role labeling can identify the roles different noun phrases play, like agents, patients, instruments, etc. Extracting subject-predicate-object triples can capture core factual statements made in the text. And labeling relations like “person X founded company Y” can extract precise details about key entities. By parsing out and cataloging these semantic relations, search algorithms can look beyond keyword matching to better model pages’ focus, events described, and reliability.

Practical examples:

  • Flagging pages containing contradicting semantic relations could influence rankings by detecting conflicting/inaccurate info.
  • Indexing pages’ subject-predicate-object relations enables more semantic, intent-based search.
  • Identifying pages with more definitive factual relations may suggest greater authority/accuracy.

Three Potential Actionable SEO Ideas

  • For key page entities, specify semantic relationship attributes like creator, user, manager, location to provide additional context.
  • Use schema.org structured data to annotate entities, their attributes, and their connections to one another.
  • Create an entity-relationship graph visualization on the site illustrating connections between key entities discussed.

Co-occurrence Network Analysis

This studies networks of words that appear together in texts to model connections. For example, it maps out that “pancake” and “syrup” often occur together.

Modeling the networks of co-occurring words and entities on webpages can provide useful clues about their semantic themes and topics. Constructing graphs where nodes are vocabulary and edges show statistical co-occurrence allows search algorithms to map out the key concepts contained within the text. Community detection can identify densely linked nodes that likely correspond to topic clusters. Analyzing the centrality of nodes in the network can uncover dominant themes. Comparing the co-occurrence networks across pages can help segment documents into related groups based on shared concepts. By moving beyond just matching keywords to modeling semantic connections, search engines can better organize and rank pages for relevance.

Practical examples:

  • Clustering pages based on similarities in their co-occurrence networks can power more relevant topic-based search.
  • Identifying central, high frequency nodes may help distill pages’ primary foci.
  • Connecting pages with shared uncommon co-occurring concepts could suggest deeper topical relevance.

Three Potential Actionable SEO Ideas

  • Include a topic analysis widget on pages visualizing graphical connections between discussed concepts.
  • Create highly interconnected content focused on building out associative chains of related keywords and entities.
  • Develop an internal site graph database tracking statistical co-occurrences of terms to inform optimization decisions.

Named Entity Recognition

This labels words in the text that are names of things like people, places, and companies. For example, it identifies “Barack Obama” as a person’s name.

Identifying named entities mentioned on webpages like people, organizations, locations, dates, etc. provides useful signals about page content that go beyond keyword analysis. The prominence and relations of these real-world entities can reveal the focus and provenance of the page text. For example, a high incidence of locations may indicate geo-specific content. Identifying authoritative sources like public figures or experts mentioned could bolster page trustworthiness. Analyzing trends in entity types over time can factor into assessments of freshness as well. By leveraging these entity-based insights, search engines can filter and rank pages in ways that better match entities of interest to the user.

Practical examples:

  • Prioritizing pages mentioning sought-after people or organizations caters results to user intent.
  • Weighing pages that cite more reputable entities and sources may improve reliability of results.
  • Tracking shifts in mentioned entities over time enables filtering results by recency.

Three Potential Actionable SEO Ideas

  • For each page, list out key people, organizations, locations, and brands related to the topic to provide a clear entity signal.
  • Provide schema-structured data for prominent named entities as @abouts and @mentions. 
  • Create an entity explorer navigation allowing users to pivot between related entities mentioned across the site.

Semantic Role Labeling

This labels what role words play in a sentence, like “agent” or “theme”. For example, it tags “boy” as the “agent” and “cookie” as the “theme” in “The boy ate the cookie.”

Semantic role labeling involves detecting the roles played by entities within predicates describing events or actions. This provides useful insights for search engines into the nature of the content described on a webpage. For example, identifying agents, patients, instruments, etc. allows search algorithms to categorize pages based on key participants and actions they mention. Distinguishing pages that focus on certain desired roles, like highly relevant agents or patients, enables more intent-based matching. Semantic roles can reveal details about events, like magnitude, duration, frequency, etc. to aid assessments of importance and relevance. Overall, semantic role labeling provides another lens for understanding the meaning of text that can ultimately improve search retrieval and ranking.

Practical examples:

  • Prioritizing pages that highlight relevant target participants, like desired agents or patients, caters better to precise user intent.
  • Identifying pages detailing high-magnitude events or frequently occurring actions provides signals of importance.
  • Semantic role information enables filtering pages to match or exclude particular types of events or actions.

Three Potential Actionable SEO Ideas

  • Structure content to clearly identify agents, patients, instruments, etc. related to key actions and events described.
  • Annotate content with semantic tags labeling noun phrase roles like <Agent> or <Theme> to support extraction.
  • Visually distinguish people, places, and things central to discussed events through typographic highlighting.

EAV Table Analysis

This analyzes tables structured with entities, their attributes, and attribute values. For example, products with prices and sizes in tables or breast cancer (E); Treatments (A); chemotherapy, mastectomy, lumpectomy (V).

For webpages containing structured data in an entity-attribute-value format, analyzing these tables provides shortcuts for search algorithms to directly interpret the page’s content. The entities, their associated descriptive attributes, and the attribute values provide a pre-parsed view of key page information. This avoids the need for more complex NLP techniques to extract facts buried in unstructured text. Analysis of structured data also allows the segmentation of pages based on the types of entities they contain and their related attributes and values. This supports a more granular, intent-based search and ranking of results.

Practical examples:

  • Matching sought-after entity types, attributes, and values enables very precise filtering of results.
  • Ranking pages based on the relevance of their structured data fits user queries with less ambiguity.
  • Analyzing the update frequency of dynamic structured data can inform assessments of page freshness.

Three Potential Actionable SEO Ideas

  • Use EAV tables to create master sitemaps and content outlines for topical breadth and depth of coverage. 
  • Use schema.org terms so search engines can directly interpret descriptions.
  • Maintain dynamically updated entity data like glossaries, directories, event listings, etc. in structured databases. 

Distributional Semantics

This represents word meaning through statistical patterns of how words occur together. For example, the meaning of “pancake” based on words like “syrup” and “breakfast” that are often nearby.

Modeling the distributional semantics of words on a webpage, based on patterns of co-occurrence across large corpora, provides powerful contextual clues for search algorithms. By representing terms as high-dimensional vectors encoding their meaning, search engines can effectively measure semantic similarity beyond literal keyword matches. Comparing distributional profiles allows search algorithms to connect pages using related concepts, synonyms, analogies, and more. Distributional semantics also enables the categorization of pages based on their conceptual focus. This provides the basis for improved relevance ranking, query expansion, and more intelligent information retrieval overall.

Practical Examples:

  • Identifying pages using distributionally similar terms expands matches beyond literal keywords.
  • Measuring vector similarity enables nuanced assessments of topical relevance.
  • Segmenting pages based on distributional semantics powers better topic-focused search.

Three Potential Actionable SEO Ideas

  • Track semantic usage metrics over time to identify emerging trends and model the contextual meaning of important terms.
  • Build a usage graph between site terms to refine clusters of related concepts and expand keyword connection pathways.
  • Show dynamic word clouds on pages to visualize keyword distributions and conceptual associations.

Meronymy (Part-Whole Relation)

This looks at part-whole relationships between concepts and words. For example, it links “room” as part of “house”.

Analyzing meronymic part-whole relations expressed on webpages can provide search engines with useful hierarchical information about mentioned entities. Identifying pages that describe component parts of larger wholes enables better matching for navigational queries trying to drill down by attributes. For example, a page about “wheel alignment” may be highly relevant for a search seeking information on “auto maintenance”. Modeling part-whole hierarchies also provides overall categorical context about pages’ entities, like a “fin” being part of a “shark”. This allows search engines to leverage inferred connections between pages based on their related place within an ontological hierarchy.

Practical Examples:

  • Prioritizing pages focusing on parts of a queried whole aids navigational intent.
  • Connecting pages that mention hierarchically related meronyms and holonyms improve relevance.
  • Analyzing the balance of parts vs wholes discussed provides clues about page specificity.

Three Potential Actionable SEO Ideas

  • Clearly explain parts, components, steps for key wholes like products, services, processes, etc.
  • Use structured data itemList markup to detail parts-whole relationships between entities.
  • Create visual navigational site maps tying broader wholes to increasingly specific parts.

Super-Subordinate Relation

This looks at broad-narrow relationships between concepts, like “animal” and “dog”. It links general terms to more specific ones.

Identifying super-subordinate relationships between entities referenced on a webpage, including hypernyms, hyponyms and ISA relations, can help search algorithms better organize and categorize page content. Recognizing that a page mentioning “golden retrievers” also relates to “dogs” and “animals” categorizes it into a hierarchical taxonomy. This allows search engines to connect that page to broader, more general queries seeking information about “dogs”, even if that exact term is not present. Analyzing distribution of superordinates and subordinates discussed also provides signals about the contextual specificity of pages. This additional topical and categorical understanding enables improved relevance ranking.

Practical Examples:

  • Connecting pages to taxonomically broader concepts expands topical relevance.
  • Weighing specificity based on subordinates vs superordinates mentioned improves ranking.
  • Leveraging taxonomies aids query understanding and intent disambiguation.

Three Potential Actionable SEO Ideas

  • Link site content honing in on specific niches to overview pages focused on the broader category (aka Pillar Pages and supporting articles). 
  • Utilize Has-a or Is-a hierarchies in site taxonomy, tags, categories, and link structures between pages.
  • Include tables detailing taxonomy classes/subclasses related to key entities on topic pages.


This connects different manners of doing something to the action itself. For example, “whispering” and “shouting” are troponyms of “speaking”.

Modeling troponymic relations, which connect manner of action to actions, provides useful contextual understanding for search algorithms. Identifying pages detailing specific “ways” of doing things allows search engines to better match them to queries seeking that type of information at an appropriate level of granularity. For example, pages discussing the troponyms “whispering” or “shouting” may be highly relevant for queries about “talking”. Analyzing troponyms also enables categorization and clustering of pages based on focus on common actions. This can power better recommendation of pages covering different methods and sub-topics around a high-level issue.

Practical Examples:

  • Surfacing pages focused on specific manners of queried actions targets user intent.
  • Clustering pages discussing related troponyms enables discovery of specialized content.
  • Weighing troponym distributions helps assess topical breadth and specificity.

Three Potential Actionable SEO Ideas

  • Provide how-to content with steps drilling down on exact methods, integrations, configurations, etc. for target activities.
  • Outline different approaches, techniques, mindsets related to goals in tiered structures linking general to increasingly specific.
  • Include dynamic filters allowing users to pivot views on a topic—like product uses—by various troponymic facets.

Corpus-Based Analysis

This analyzes statistical language patterns across large collections of texts called corpora. For example, studying word frequencies across newspaper articles.

Analyzing statistical patterns in word usage across entire text corpora provides useful signals for search engines about the focus and meaning of pages. Techniques like distributional semantics modeling, word embedding, and lexical chaining rely on observing relationships between terms across a large body of texts. This enables search algorithms to interpret pages based on usage profiles of terms they contain, even in the absence of obvious keyword matches. Corpus-based analysis also facilitates categorization of pages using semantic similarity measures instead of just surface word matches. Incorporating these corpus insights enables search systems to retrieve and rank pages in ways more aligned with their true relevant meaning.

Practical Examples:

  • Corpus-derived word embeddings allow matching pages based on conceptual similarity, not just keywords.
  • Identifying lexical chains can link pages that share common themes or entities, even without overlap.
  • Clustering pages by corpus-based usage profiles of terms enables better semantic search.

Three Potential Actionable SEO Ideas

  • Add links within content to Wikipedia/Wiktionary for disambiguation and grounding meanings from corpus usage.
  • Build an internal corpus of reference documents on topics to track how new content compares for keyword usage patterns.
  • Show contextual word clouds on pages generated from statistical language models based on corpus analysis.

Lexical Chain Analysis

This finds chains of related words that occur together in text. For example, a sequence like “house”, “room”, “kitchen” relates concepts.

Constructing lexical chains from webpages provides useful insights for search engines into key themes, concepts and relations described by the content. Tracing sequences of semantically related terms strung together throughout the text acts as a summary of important page topics and entities. This enables matching and ranking pages for queries seeking certain concepts or themes, even in absence of exact keyword matches. Length and centrality of lexical chains also helps search engines gauge the prominence and cohesiveness of topics contained within pages. Overall, lexical chain analysis provides a view into semantic essence of pages that goes beyond superficial keyword statistics.

Practical Examples:

  • Matching pages containing lexical chains related to query topics improves relevance.
  • Assessing chain length and centrality provides signals of topic primacy and content cohesion.
  • Linking pages with shared strong lexical chains indicates close semantic relationships.

Three Potential Actionable SEO Ideas

  • Structure content using cohesive linking phrases to connect central keywords and concepts throughout the text.
  • Design site taxonomy and internal links to create lexical chains linking pages touching related concepts.
  • Add contextual tag cloud widgets promoting the serendipitous discovery of pages connected by lexical chaining.

Topic Modeling

This uses statistics to find abstract topics that occur across documents. For example, discovering themes like “cooking” across recipes and blogs.

Applying topic modeling processes like LDA reveals the underlying semantic themes present within webpages based on aggregated word usage patterns. By clustering words and terms into probabilistically derived topics, search engines can overcome reliance on just keyword matching. Instead they can categorize and connect pages based on their composition of latent semantic topics, even without obvious term matches. Analyzing distributions over these learned topics provides insight into the primary foci of pages. Topic modeling thus enables more meaningful relevance ranking, categorization, and recommendation of conceptually related content.

Practical Examples:

  • Discovering pages highly weighted towards queried topics improves relevance even without keywords.
  • Recommending pages containing similar topic distributions suggests related content interest.
  • Organizing pages by their topic distributions enables better discovery by users.

Three Potential Actionable SEO Ideas

  • Visualize generated topic models through site page badges, tag clouds, and content recommendations.
  • Create topical hubs gathering resources linked across pages strongly associated with target subjects.
  • Develop workflows to continuously update topic models as new content gets added to better organize pages.

Cluster Analysis

This groups things like documents or words based on shared attributes using algorithms. For example, clustering articles by topic words they contain.

Applying cluster analysis techniques enables search engines to categorize and group webpages based on shared characteristics. This provides an alternative to traditional keyword-based indexing that relies on surface term matching. Clustering algorithms can leverage various features like word usage, semantics, entities, structure, etc. to detect pages about related concepts. These clusters essentially create topic-based groupings of content, useful for serving users exploratory discovery of subjects related to their queries. Cluster membership also provides additional signals for ranking pages within search results through algorithms like cluster-based retrieval.

Practical Examples:

  • Presenting topically cohesive clusters of pages helps users explore niche interests.
  • Weighting pages by cluster relevance matches queries with less ambiguity.
  • Recommending closely grouped pages satisfies niche information needs

Three Potential Actionable SEO Ideas

  • Show topical clusters related to page contents through visualizations or content links for exploratory discovery.
  • Use clustering to inform site architecture and internal linking to connect pages around conceptual groups.
  • Apply cluster analysis regularly to help focus new content creation on building out strategically meaningful topics.

Association Rule Mining

This finds interesting associations between pieces of information like products purchased together. For example, people who buy cereal often also buy milk.

Mining association rules from webpage content provides insights about commonly co-occurring entities, attributes, and relationships. This detection of patterns like “product X is often purchased with product Y” within web documents enables new relevance signals for search ranking. Pages exhibiting associations strongly tied to user query terms can be prioritized due to implicitly related content. Associations also aid semantic query expansion to surface pages using related terminology. Analyzing evolution of association rules over webpage corpora timelines also informs assessments of freshness and importance.

Practical Examples:

  • Prioritizing pages containing queried associations surfaces implicitly relevant content.
  • Expanding queries based on related associated rule entities improves recall.
  • Tracking trending and disappearing associations helps gauge content urgency.

Three Potential Actionable SEO Ideas

  • Structure unique product/service/content bundles informed by association rule mining patterns.
  • Highlight related purchases, page views, etc. driven by association rule recommendations.
  • Periodically reassess site content adjacencies and links based on emerging associations in usage data.

N-Gram Analysis

This looks at sequences of multiple words together, like pairs (bigrams) or triplets (trigrams). For example, studying the frequency of “strong tea”.

Examining n-gram use and frequencies within webpages provides useful signals about content topics and quality. Uncovering commonly used phrases acts as an additional metric beyond keyword analysis for understanding topical focus. Statistics on n-gram makeup also enable useful comparisons between pages to identify outliers with unusual phrasing. Normalizing metrics like term frequency-inverse document frequency help assess the informative value provided by certain n-grams based on their specificity. Analyzing n-gram evolution over time also provides clues into content freshness and importance of pages.

Practical Examples:

  • Matching pages with topical n-grams boosts relevance even in absence of keyword matches.
  • Flagging pages with unusual n-gram frequencies helps filter lower quality content.
  • Prioritizing pages with more distinctive n-grams rewards unique, specific content.

Three Potential Actionable SEO Ideas

  • Research industry specific keywords, phrases, and terminology to naturally integrate explanatory n-grams.
  • Use n-gram inclusion as a metric when evaluating content, prioritizing posts with higher densities of topic n-grams.
  • Add quotations highlighting relevant key n-gram phrases to help reinforce semantic matching signals.

Collocation Analysis

This finds which words tend to appear together in phrases, like “strong tea”. It looks at these linguistic collocations.

Identifying characteristic collocated words and phrases in webpages provides useful signals about content topics and style. Statistics on common term combinations indicate semantic associations between concepts covered. Comparing collocation patterns between pages can also help segment content based on subject matter through techniques like similarity clustering. Analyzing collocations additionally provides cues about tone and level of formality based on phrasing choices. Unusual or atypical collocations may also indicate lower quality or autogenerated content worth demoting. Overall collocation analysis enables search engines to interpret pages beyond isolated keywords.

Practical Examples:

  • Clustering pages by shared collocation patterns enables better topical search and discovery.
  • Identifying formal/informal collocations informs stylistic text classifiers to match user preferences.
  • Flagging pages with unusual or one-of-a-kind collocations helps filter lower quality content.

Three Potential Actionable SEO Ideas

  • Track collocations across new content to identify novel or unusual phrasings needing clarification.
  • Query collocation databases to find relevant word partnerships to integrate within copy.
  • Implement a site search to retrieve pages containing specific collocated phrases.

Semantic Field Analysis

This studies groups of words related by meaning, like different sports terms. For example, analyzing how words like “soccer”, “goalie”, and “foul” are related.

Examining clusters of related words and concepts present on pages provides a useful view into their themes and topics. Semantic field analysis goes beyond isolated terms to model meaningful groups of related vocabulary. This enables search engines to interpret pages based on which semantic fields they exhibit, even without direct keyword matches. Comparing distribution over fields also allows search algorithms to classify pages by subject matter and genre. Users likewise can browse or filter search results based on semantic field composition matching their interests and goals.

Practical Examples:

  • Browsing search results by predominant semantic field facilitates exploratory discovery.
  • Weighting pages by semantic field relevance improves topical matching without keywords.
  • Comparing field distributions identifies conceptually related pages despite lexical differences.

Three Potential Actionable SEO Ideas

  • Organize site sections around semantic fields like industries, product categories, disciplines, etc. with highly related vocabulary on pages.
  • Crosslink pages from associated semantic fields to reinforce field connections in site information architecture.
  • Prioritize content-expanding edges of semantic fields rather than redundant concepts in the dense core.

Environmental Scanning

This monitors outside information like news, data, and social media relevant to an organization. For example, scanning industry reports and competitors’ tweets.

Monitoring signals from a web page’s broader ecosystem, like social shares, inbound links, and platform interactions, provides useful contextual clues for search ranking beyond just on-page content analysis. Metrics on virality, external validation, and user engagement act as indicators of popularity and trustworthiness. Trends in referrer patterns also give clues about shifting attention and hot topics. Considering these environmental factors in scoring provides a more dynamic, responsive model of relevance compared to static content analysis alone.

Practical Examples:

  • Develop analytics dashboards tracking site KPI time series, referral patterns, search/social signals to gain competitive insights.
  • Perform routine competitive audits assessing strategy changes like new products, branding, and discounts to identify threats and opportunities.

TF-IDF Analysis

This measures how important a word is by comparing its frequency in a document vs. the collection. For example, “predator” has higher TF-IDF in an article about panthers compared to the term “fur.”

Leveraging statistics like term frequency-inverse document frequency (TF-IDF) provides useful signals for search engines to evaluate the informative significance of words within webpages. TF-IDF measures the relevance of terms based on their frequency within a document compared to the inverse of their prevalence across all documents. This helps surface distinctive keywords strongly associated with a page but rarely seen elsewhere. High TF-IDF terms often indicate the core informative content. Prioritizing pages with higher TF-IDF scores for their keyword matches thus helps retrieve results tightly focused on relevance to the query.

Practical Examples:

  • Matching important yet rare query terms with pages featuring high TF-IDF improves relevance.
  • Summarizing pages based on high TF-IDF keywords identifies salient topics.
  • Comparing TF-IDF keyword distributions enables similarity ranking of pages.

Three Potential Actionable SEO Ideas

  • Target integration of technical vocabulary and industry terminology likely to be unique and keywords with high IDF weights.
  • Set up Google Alerts for high TF-IDF keywords to prompt creation of content when new relevant documents emerge.
  • Evaluate content/page value based on TF-IDF metrics—prioritizing those with distinct meaningful terms versus common words.

Frequency Analysis

This simply looks at how often words or concepts appear. For example, analyzing how many times “elephant” appears on a page about elephants.

Examining the raw term and entity frequencies observed within webpages enables useful insights for search ranking and classification. The degree of repetition of keywords and concepts provides clues about their relative importance to the content. Comparing frequency distributions can help segment pages discussing common vs niche topics based on relative differences. Changes in word usage rates over time also inform assessments of content freshness and attention trends. Overall, straightforward term frequency analysis provides a simple yet effective method for gauging page aboutness.

Practical Examples:

  • Prioritizing pages where query terms appear more frequently improves relevance targeting.
  • Clustering pages by shared frequency patterns enables topic-based search.
  • Identifying rising term frequencies over time highlights trending topics.

  • Monitor shifts in topical focus based on keyword densities to realign content creation and optimization priorities.
  • Direct site search auto-suggestions and recommendations using high-frequency significance keywords.

Semantic Disambiguation

This figures out the intended meaning of ambiguous words based on context. For example, determining if “bat” refers to the animal or baseball bat from context.

Resolving ambiguous words and phrases found on webpages based on intended meaning and context improves search engines’ comprehension. Techniques like word sense disambiguation leverage surrounding semantics to determine appropriate sense. Discovering pages using terms in senses closely matching the user intent enables better relevance matching. Semantic disambiguation also reduces noise from retrieving pages that happen to share ambiguous keywords but exhibit unrelated usage. Machine learning models can additionally leverage disambiguation to reduce dimensionality of semantic features.

Practical Examples:

  • Disambiguating query terms limits irrelevant results sharing only ambiguous keywords.
  • Detecting specific sense usage helps match nuanced semantic intent.
  • Disambiguation enables grouping of pages discussing words in similar senses.

Three Potential Actionable SEO Ideas

  • Link ambiguous phrases to Wikipedia pages or provide definitions from dictionaries/glossaries to clarify intended meanings.
  • Use structured data like schema.org to tag word senses to assist interpretation.
  • Include comparisons highlighting differences when multiple potential senses of words are relevant to avoid confusion.

Stylistic Analysis

This examines attributes like formality, complexity, and tone of writing style. For example, detecting whether the language is professional versus casual.

Examining attributes related to writing style, tone and readability of webpages provides useful signals about content type, quality and target audience. Statistics on vocabulary complexity, sentence structure, formality, and media use classify pages across stylistic dimensions. Search engines can use these linguistic style insights to retrieve results better matching user preferences, like formal registers for scholarly queries versus casual language for pop culture searches. Style also provides proxies for assessing expertise level of pages. And highly atypical styles may indicate autogenerated or copied content of lower quality.

Practical Examples:

  • Classifying pages by vocabulary complexity enables targeting results to user expertise.
  • Identifying formal/informal tone facilitates matching register to context and intent.
  • Flagging pages with unusual style metrics helps filter lower quality content.

Three Potential Actionable SEO Ideas

  • Assess site content across style dimensions like formality, complexity, etc. to ensure appropriate register and reading level for the audience.
  • Maintain an authoritative, consistent linguistic style across directories, product descriptions, blog posts, etc. to match user expectations.
  • Flag outlier pages exhibiting atypical styles to identify potential quality issues or misalignments with target users

Sentiment Analysis

This detects attitudes, opinions, and emotions expressed in text. For example, analyzing whether a movie review is positive or negative.

Detecting sentiment, opinions and attitudes expressed on webpages provides search engines useful contextual understanding beyond just topical facts. The subjective nature of content factors into relevance for many search intents seeking reviews, commentary, or critique.

  • Apply entity resolution to consolidate user profiles, content metadata, and other data sources with overlapping object references.
  • Tag or link ambiguous entity mentions to disambiguated identifiers or knowledge base profiles.

Entity Linking

This links mentions of entities to knowledge bases about them. For example, linking “Barack Obama” to his Wikipedia article.

Linking entity mentions on webpages to knowledge bases provides unambiguous conceptual grounding and expanded contextual understanding. Recognizing real-world entities enables direct integration of factual knowledge. Linking together entities into graphs captures semantic relations and events extracted from the content. This rich network represents key actors, concepts and relationships described by pages. By integrating structured knowledge, search systems move beyond bags-of-words to represent salient entities and relations.

Practical Examples:

  • Linking entities to knowledge bases unifies semantic interpretation across data sources.
  • Constructing entity relation graphs directly answers semantic queries.
  • Recommending related entities using knowledge graph connections enables exploratory discovery.

  • Visually distinguish linked entities on pages through styling like icons, badges, rich hover previews.
  • Enable entity-based site exploration by generating suggestion widgets with related entities extracted from page contents.

Entity Co-Reference Resolution

This identifies multiple expressions that refer to the same entity. For example, linking “Mr. Obama” and “Barack” as referring to the same person.

Identifying multiple expressions and mentions referring to the same entities across webpage contents connects knowledge about real-world objects discussed. Different references to a shared entity strengthen signals about its contextual relevance. Connecting pronouns and abbreviated aliases back to full entity specifications also improves coherence and accuracy. Analyzing concentrations of entity mentions further highlights dominant page topics. Overall, co-reference resolution enhances understanding by tying disparate expressions together into unified semantics about key entities.

Practical Examples:

  • Linking all pronoun and alias references to canonical full entity names clarifies object focus.
  • Aggregating signals from related co-referring expressions improves relevance recognition.
  • Identifying key entities based on high frequencies of co-referenced mentions assists summarization.

  • Implement site search with filters to narrow results by entity roles, relationships, attributes, etc. inferred through co-reference resolution.
  • Assess content quality by analyzing density of resolved entity references as a proxy for informational value.

Entity Attribution

This identifies the sources and provenance of entities. For example, analyzing who created a piece of data.

Analyzing statements of attribution, ownership, responsibility and influence associated with entities referenced in webpage text provides useful context. Google uses this in its Experience-Expertise-Authority-Trust quotient. Extracting source relations and provenance conveys important real-world perspectives. For example, identifying influential creators and authors provides authority clues for ranking and credibility. Sentiment expressed towards entities also enables perspective-based clustering. Overall, modeling attribution patterns helps search engines better situate page contents relative to significant sources and stakeholders.

Practical Examples:

  • Visually associate entities with sources through author boxes, inline citations, knowledge panel sidebars, and backlinks.
  • Enable attribution-based content filtering by source reliability, political affiliation, company, etc. matching verification preferences.

Entity Classification

This categorizes entities into types and classes. For example, classifying people, places, organizations, etc.

Categorizing entities mentioned on webpages into a taxonomy class hierarchy enables better semantic comprehension for search compared to treating names as just strings. Recognizing class membership provides critical context – location entities behave differently than person entities. Classes also enable inheritance of attributes and relationships from more general types. Overall, entity classification gives structure to extracted knowledge which improves downstream reasoning. Classes additionally allow grouping pages discussing similar types of objects.

Practical Examples:

  • Organizing entities into a class hierarchy leverages inherited knowledge applicable to subclasses.
  • Disambiguating terms by binding to specific entity classes reduces confusion.
  • Clustering pages by distributions over entity classes enables conceptual exploration.

Giving Credit Where Credit Is Due

I believe in giving credit where it’s due. My friend Ed Baker, whose website can be found at https://www.edwardabaker.com/, compiled this initial list of models and, with Rob Beal, has developed an incredible tool, called ContentMaxima, designed to aggregate the key advantages produced by each model for a specific keyword, search query, or entity. Ed has granted us access to beta-test the tool’s results, and it’s proving to be fantastic. This experience sparked my curiosity about how each model might be incorporated further into an SEO strategy. Hence, this long article. Our testing has shown that the tool is intriguing and useful for content mapping and creating article outlines. It eliminates the uncertainty in site structures and article outlines by assigning weight to related keywords/entities, based on the presentation of that term in relation to the primary keyword by each of the 63 models. Essentially, the tool identifies the nearest nodes based on the LLM models previously listed.
