What it is
Search used to be about matching keywords. Now engines and AI systems think in entities: a person, a company, a product, a place, each with attributes and links to other entities. Entity SEO is the work of making your brand a clearly defined entity that machines recognize and describe correctly, rather than a string of words they have to interpret.
Why it matters
Entity recognition is the layer underneath AEO and GEO. Before an AI system can cite you accurately, it has to know who you are and trust the facts about you. If your name, role, and details are consistent and well-marked across the web, a model represents you correctly. If they are scattered or contradictory, it conflates you with something else or leaves you out. In crowded categories, being a recognized entity is what separates getting cited from getting skipped.
What to do
Mark up your organization, people, and products with schema so the facts are explicit. Keep your name, title, and key details identical everywhere they appear, from your site to your profiles. Earn mentions on sources that search engines and AI already trust, and connect related pages so the relationships between your entities are clear.
