Entity SEO and the Knowledge Graph: How Search Engines Understand People, Brands and Things

When Google launched its Knowledge Graph in May 2012, it described the shift as moving from "strings to things". Instead of matching words on pages, search engines began building a database of entities, real-world people, places, organisations, products and concepts, and the relationships between them. Today, entity understanding powers knowledge panels, AI-generated answers, voice assistants and recommendations.

An entity is a uniquely identifiable thing or concept. "Jaguar" can mean an animal, a car brand or a sports team; entity understanding lets search engines work out which one you mean from context.

Each entity has:

They combine signals from:

AI assistants and generative search systems rely heavily on this understanding to decide which sources describe an entity accurately.

Your official About page should clearly state who you are: legal name, brand name, founding date, founders or leadership, location, what you do and contact details.

The `sameAs` property connects your site to your official profiles elsewhere, helping search engines confirm they refer to the same entity.

Make sure your name, description, logo, address and leadership details match across your website, social profiles, business directories, press releases and app stores.

Coverage by reputable publications, industry associations and official registries corroborates your entity's details. Only notable entities meeting its policies belong on Wikipedia or Wikidata; do not create promotional entries.

For publishers, author pages with credentials, bios and links to professional profiles help establish expertise, supporting what Google calls E-E-A-T (experience, expertise, authoritativeness and trustworthiness).

If a knowledge panel appears for your brand or yourself, you can request verification and suggest corrections through Google's process.

No. Knowledge panels are generated automatically from available information. You can verify and suggest edits but not buy one.

It is not a direct ranking boost, but it helps search engines understand content and enables rich results.

Yes. Clear, consistent and corroborated entity information makes it more likely that AI systems describe your organisation accurately.

Search has moved from keywords to understanding. Define your entity clearly, mark it up, keep it consistent across the web and earn authoritative corroboration, and both search engines and AI assistants will represent you more accurately.
