Google stopped being a keyword-matching machine years ago. Modern search runs on entities: distinct things such as a business, a person, a suburb or a service, each with properties and relationships the engine stores and reasons about. Entity SEO is the work of making sure Google holds a clear, confident record of who you are, what you do and where you do it. It has always mattered; now that AI tools compose answers by consulting those same records, it is fast becoming the difference between being recommended and being invisible.
What an entity is, in plain English
An entity is a thing, not a string. The string plumber Melbourne is text to match; the entity is a specific plumbing business with a name, an address, an owner, services, reviews and relationships to other entities. Google's index of these things, the Knowledge Graph, holds billions of them along with the connections between them. When Google is confident about an entity, it can answer questions about it directly, show a knowledge panel for it, and connect a vague query to your specific business.
Entity SEO, then, is not a new bag of tricks. It is the discipline of feeding that graph consistent, corroborated facts until the machine's picture of you is sharp.
A Melbourne example makes it concrete. Fitzroy is an entity Google knows sits inside Melbourne; emergency plumbing is a service connected to plumber; your business can be an entity connected to both. Once those connections exist, a search like burst pipe Fitzroy can surface you even if that exact phrase appears nowhere on your site, because the graph, not the text, is doing the matching.
Why entity SEO matters more every year
Two shifts drive it. First, search itself: Google increasingly ranks and displays things rather than just pages, especially in local results, where the map pack is a ranking of businesses rather than URLs. Second, AI: when ChatGPT, Gemini or an AI Overview writes an answer, it names brands it can identify with confidence. A business that machines only half-recognise gets summarised vaguely or skipped. That is why entity SEO now sits at the foundation of AI SEO: you cannot be cited by name if the machine is not sure what your name refers to.

How Google builds its picture of you
Google assembles an entity from evidence scattered across the web: your website, your Google Business Profile, directories, social profiles, reviews, news mentions and the sites that link to you. It cross-references everything. When your name, address, categories and descriptions agree everywhere they appear, confidence in the Knowledge Graph rises. When they conflict, old addresses, inconsistent business names, two half-maintained profiles, the machine hedges, and hedging costs you visibility.
Corroboration from independent sources counts most. Anyone can say anything on their own site; an entity becomes solid when other trusted places repeat the same facts. That is one reason mentions and citations matter beyond any link value, and why tracking where AI tools mention your brand has become part of the job. Entity SEO extends well past your own website.
The signals that define your entity
Four groups do most of the work. Structured data first: schema markup on your site states your identity in a format machines parse directly, covering your name, type, address, founder, services and the sameAs links that tie your site to your official profiles. Our guide to schema markup explains the format in plain English. Second, your Google Business Profile, which for a local business is the closest thing to editing your entity record directly; keeping it complete and active is covered in our Business Profile optimisation guide.
Third, consistency: one exact business name, address and phone number everywhere you are listed. Fourth, depth: covering your subject thoroughly enough that Google associates you with the topic itself, which is the same work that builds topical authority. Entities and topics reinforce each other; the clearer Google is about who you are, the more it trusts what you publish.
Your About page carries more weight in this work than most sites give it credit for. It is the natural home for the facts machines look for: who founded the business, when, where it operates, which associations it belongs to, the credentials behind the expertise. Write it for a sceptical reader and you have written it for the graph as well.
The mental model: a page ranks, an entity gets recommended. Traditional SEO earns the visit; entity SEO earns the trust that makes machines name you unprompted.
Entity SEO and AI search
AI assistants raise the stakes because they compress the web into a short answer with a few names in it. Each of those names is an entity the model can resolve confidently from its training data and live retrieval. The practical work of AI and GEO visibility therefore leans hard on the entity layer: clean structured data, consistent facts, and corroborating mentions in the sources the engines already read. Brands that invested in entity SEO early tend to be the ones AI tools describe accurately and cite by name.
The same clarity pays off in quieter ways: better matching for voice queries, eligibility for rich results, a knowledge panel that occupies real screen space on brand searches. Entity SEO rarely produces one dramatic win; it raises the confidence behind every result you already appear in.

Where to start
Begin with a search for your own business name plus your suburb, and read what comes back: the knowledge panel or its absence, the accuracy of your Business Profile, the description AI tools give when asked about you. Then fix things in order: schema markup on the homepage stating exactly who you are, sameAs links to every real profile, a Business Profile brought fully up to date, and a sweep of your major listings for conflicting details. None of it is glamorous, and all of it compounds. Entity SEO is mostly the discipline of saying the same true things about yourself everywhere machines look. Give it a season and re-run the same searches; graph updates lag the fixes, and the knowledge panel that eventually appears is your confirmation that the machine finally has you straight.
