Optimising a site to be associated with one or more entities — people, places, organisations, products, concepts — in Google's Knowledge Graph and similar systems. Practical tactics: structured data (
schema.org/Organization, Person, Product), consistent NAP (name/address/phone) across the web, citations from authoritative sources, sameAs links to Wikipedia/Wikidata/LinkedIn, and clear topical pages explaining the entity. Entity SEO matters most for branded queries, knowledge-panel eligibility, and AI-search citations, where Google increasingly returns entity-level answers rather than ranked URL lists.
