Entity SEO is optimisation organised around entities — distinct, well-defined things such as a company, person, place, product, or concept — rather than around keyword strings alone. Search engines maintain knowledge graphs that store entities and the relationships between them, and they increasingly interpret queries and content by mapping words to entities.

Entity SEO is optimisation organised around entities — distinct, well-defined things such as a company, person, place, product, or concept — rather than around keyword strings alone. Search engines maintain knowledge graphs that store entities and the relationships between them, and they increasingly interpret queries and content by mapping words to entities.
Entity SEO is the practice of making a site's subject matter, and the site or brand itself, clearly identifiable as entities and correctly connected to related entities.
In practice it means being consistent and explicit about what things are: using unambiguous names, marking up content with structured data that states entity types and properties, linking to authoritative references, keeping consistent identity information across the web, and covering a topic in a way that reflects the real relationships between its concepts. The goal is for a search engine to understand not just that a page contains certain words but what it is about and how that fits its model of the world.
In context
For an iGaming affiliate, entity SEO connects directly to topical authority and E-E-A-T. Making the site an entity means consistent brand naming, an about and organisation markup, named authors with real credentials and profiles, and consistent identity signals across the web. Making the content entity-rich means that a glossary defines each concept as a thing with properties and relationships — this term is a type of that, relates to these, is regulated by that body — and links terms to each other and to authoritative external references, so the whole glossary reads to a search engine as a connected model of the iGaming domain rather than a pile of keyword pages.
This is a good fit for a large bilingual glossary specifically. Each term page can carry structured data identifying it as a defined term within a defined term set, use the canonical name plus recognised synonyms, state what field it belongs to, and cross-link to related terms with meaningful anchor text.
Consistency between the English and Russian versions — same entities, same relationships, correctly hreflang-linked — reinforces that both describe the same concept. The payoff is that the site becomes a recognised reference on the subject: better eligibility for knowledge-panel and rich-result treatment, more resilience to keyword-only algorithm shifts, and stronger support for the commercial pages, which benefit from sitting within a domain the search engine understands the site to be authoritative on.
Worked example
An affiliate marks up every glossary term with DefinedTerm structured data inside a DefinedTermSet, uses each term's canonical name and listed synonyms, links related terms with descriptive anchors, and keeps the EN and RU pages hreflang-paired as the same entity. Over time the site earns rich results for definition queries and its reviews gain from the domain-wide authority.
