Hummingbird fundamentally replaced much of the existing ranking algorithms.<\/p>\n<p>Through Hummingbird, Google was immediately able to include entities recorded in the Knowledge Graph for query processing, ranking and the output of SERPs.<\/p>\n<p>An entity describes the essence or identity of a concrete or abstract object of being. Entities are uniquely identifiable and therefore uniquely meaningful.<\/p>\n<p>Basically, a distinction can be made between named entities and abstract concepts.<\/p>\n<ul>\n<li><strong>Named entities<\/strong> are real-world objects, such as people, places, organizations, products, and events.<\/li>\n<li><strong>Abstract concepts<\/strong> are physical, psychological, or social in nature, such as distance, quantity, emotions, human rights, peace, etc.<\/li>\n<\/ul>\n<p>Before Hummingbird, Google primarily did keyword document matching for ranking and could not recognize the meaning of a search query or content.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_semantic_search_engine\"><\/span>What is a semantic search engine?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A semantic search engine considers the semantic context of search queries and content to better understand meaning.

It is responsible for evaluating content and then putting it in an order based on the scoring. Scoring is about the relevance of content in relation to the search query or search intent.<\/p>\n<p>Since Google also wants to evaluate the quality of content in addition to relevance, an evaluation according to E-A-T criteria must also be carried out.

The theory here is that a high level of correspondence between the entities used in a text and the relationship structures of the main entity in Google\u2019s semantic database leads to better rankings. <\/p>\n<p>That sounds logical. But let\u2019s be honest, in the end, keyword-based optimization does not differ significantly from entity-based content optimization.<\/p>\n<p>The structure of topical worlds also makes sense, although it has to be said that in times of passage ranking, the following should be considered:<\/p>\n<ul>\n<li>Up to what extent is a theme broken down into various sub-themes?<\/li>\n<li>Is separate content produced for each sub-theme?<\/li>\n<li>Is there only a holistic content asset created?<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"And_structured_data%E2%80%A6\"><\/span>And structured data\u2026\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes, structured data can help Google understand semantic relationships, but only until they no longer need it. And that will be soon.<\/p>\n<p>In my opinion, Google is so good at machine learning that they are using structured data to train the algorithms faster. <\/p>\n<p>Let\u2019s take markups for social media profiles as an example. It took only about a year from the time Google recommended its use until they announced they can <a href=\"https:\/\/searchengineland.com\/google-deprecates-social-knowledge-panel-markup-support-318755\" target=\"_blank\" rel=\"noopener\">automatically see social profiles without structured data<\/a>.<\/p>\n<p>It\u2019s just a matter of time before Google no longer needs structured data.<\/p>\n<p>Structured data is also not a good basis for an evaluation. You either have them or you don\u2019t.<\/p>\n<p>You can count all of this to semantic SEO. However, what I often miss is the global view of entities as publishers and authors. More off-page than on-page signals play a role here. Based on the relationships between authoritative and credible entities, Google wants to determine which domains and authors are the best quality sources for a topic according to E-A-T.<\/p>\n<ul>\n<li>Who is related to whom?<\/li>\n<li>Who recommends whom? <\/li>\n<li>Who hangs out with whom?<\/li>\n<\/ul>\n<p>Links and co-occurrences from Google can be used as factors for this proximity between authority entities. And by semantic SEO, I also mean optimizing them.<\/p>\n<p>While we\u2019re on the subject of co-occurrence, you should also consider how NLP works when optimizing content. Google uses NLP to identify entities and their context. This works via grammatical sentence structures, triples and tuples made up of nouns and verbs. <\/p>\n<p>That is why we should also pay attention to a grammatical simple sentence structure in semantic SEO. Use short sentences without personal pronouns and nesting. This is how we serve users in terms of readability and search engines.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_future_of_semantic_search_When_can_a_100_entity-based_Google_search_be_achieved\"><\/span>The future of semantic search: When can a 100% entity-based Google search be achieved?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>I think that in the future there will be an increasing exchange between the classic Google search index and the Knowledge Graph via an interface. <\/p>\n<p>The more entities are recorded in the Knowledge Graph, the greater their influence on the SERPs. However, Google still faces the major challenges of reconciling completeness and accuracy.<\/p>\n<p>For Hummingbird\u2019s actual scoring, the document-level entities do not play a major role. Rather, they are an important organizational element for building unweighted document corpuses on the search index side. <\/p>\n<p>The actual scoring of the documents is done by Hummingbird according to classical information retrieval rules. However, on the domain level, I see the influence of entities on ranking much higher.
