An entity is a thing, such as a person, place, organization or product, that a search engine or AI system can identify without confusing it with something else. A brand becomes a well-known entity when its identity is stated clearly in machine-readable form, linked across trusted profiles, and described the same way by many independent sources. The first two you control. The third you earn.
This article covers what Google documents about entities, what the rules on Wikidata and Wikipedia allow, and how consistent facts tie it together. It marks which statements are vendor documentation, which are industry opinion and which are our reasoning.
What is an entity, in plain English?
Think of the difference between a word and a thing. “Mercury” is a word that can mean a planet, an element, a Roman god or a car brand. An entity is one specific thing with an identity: Mercury the planet, with known facts about it.
Search engines store entities and facts about them in a knowledge graph. Documented fact: Google says knowledge panels are information boxes that appear for entities in its Knowledge Graph, and that they “are automatically generated” from various sources across the web. They update automatically as the web changes, and Google also considers feedback from the entity itself and from users.
Reasoning. AI engines face the same problem. If your brand shares a name with a common word or another company, a model has to work out which one a sentence is about. Clear identity signals reduce confusion, and fewer mix-ups mean fewer wrong answers. See our guide on fixing incorrect AI answers if that is already happening.
How do Organization schema and sameAs help?
Documented facts. Schema markup is structured data you add to your pages so machines can read facts directly. Google says Organization structured data “can help Google better understand your organization’s administrative details and disambiguate your organization” in search results, and some properties can influence which logo appears in results and in your knowledge panel. There are no required properties.
Two properties matter most for identity:
- sameAs: URLs of pages on other sites with more information about your organization, such as social or review profiles. You can list several. schema.org defines it as a reference page that “unambiguously indicates the item’s identity”, for example a Wikidata entry or official website.
- logo: Google asks for an image at least 112 by 112 pixels, crawlable.
Google suggests putting Organization markup on your home page or a single about page. A sensible set of fields: legal and brand name, URL, logo, description, founding date, address, contact page, and sameAs links to LinkedIn, YouTube, Crunchbase, your Wikidata item if you have one, and any other official profiles.
| Signal | Who controls it | What it does |
|---|---|---|
| Organization schema | You | States your identity in machine-readable form |
| sameAs links | You | Connects your site to your official profiles |
| Wikidata item | Community, with references | Gives a public, structured record of your organization |
| Google knowledge panel | Google, with your feedback | Shows what Google believes about your entity |
| Mentions on other sites | Independent publishers | Supplies the descriptions AI actually reads |
Can your brand be on Wikidata?
Documented policy. Wikidata is a free, structured knowledge base that many systems draw on. Its notability policy accepts an item if it meets at least one of three criteria: a valid link to a Wikimedia page such as Wikipedia; it refers to a “clearly identifiable conceptual or material entity that can be described using serious and publicly available references”; or it fulfills a structural need. The policy admits the guidelines are “intentionally left a bit vague.”
Reasoning. The middle criterion is the realistic route for most companies. That means serious, public references: coverage in real publications, official registries, reputable industry sources. A Wikidata item with no references is likely to be challenged. This is one more reason accurate coverage on independent sites comes first.
What are the rules on Wikipedia?
Documented policy. Wikipedia’s conflict of interest guideline says: “Do not edit Wikipedia in your own interests” and “Paid editing must be disclosed.” People with a conflict of interest are strongly discouraged from editing affected articles directly and can propose changes on the talk page instead. Anyone paid to contribute must disclose who is paying them, a requirement in the Wikimedia Terms of Use since 2014.
Our advice. Do not write your own Wikipedia article, do not hire anyone to write one without disclosure, and do not quietly edit the one you have. If your article contains an error, raise it on the talk page with a reliable source. A Wikipedia article follows from independent coverage; it is not a shortcut to it.
Why do consistent facts matter so much?
Industry practice. Local SEO calls a business’s name, address and phone number its NAP, and Moz describes a local citation as “any online mention of a business’s name, address, and phone number”. Whitespark’s 2026 expert survey still rates NAP consistency among local ranking signals, though that is expert opinion, not Google confirmation.
Documented rule for local businesses. Google Business Profile requires you to “represent your business as it’s consistently represented and recognized in the real world”, and adding unnecessary words to your business name can get the profile suspended. Local businesses manage their Google panel through Business Profile, not the knowledge panel claim process. Our playbook for local businesses missing from AI answers covers this in more depth.
Reasoning. The same discipline applies beyond local SEO. If your site says you were founded in 2019, LinkedIn says 2020, and an old article calls you by a former name, every system reading those sources has to guess. Pick one canonical version of your name, one-line description, category, founding year, headquarters and markets, then use it everywhere. After a name change, this matters even more; see our page on AI still using your old brand name.
How do mentions turn an entity into a known brand?
Reasoning. Schema and Wikidata tell machines who you are. They do not tell anyone what you are good at, for whom, or where. That comes from other people’s pages. McKinsey estimates brand-owned sites make up only roughly 5 to 10% of the sources AI search references.
Suppose a Berlin-based HR software company has clean Organization schema and a Wikidata item, but only three articles anywhere mention it. Engines can identify it, yet they have little to say. Twenty accurate mentions in HR and small business publications, each repeating the same facts in the context of “payroll for German startups,” would give engines both identity and substance to draw on, though how often it is then named still has to be measured. That is the gap our step-by-step plan for getting mentioned by AI addresses.

Frequently asked questions
Does my company need a Wikipedia page to be a known entity?
No. Wikidata accepts items that are clearly identifiable and described by serious, publicly available references, even without a Wikipedia article. Google also builds knowledge panels from many sources across the web. Wikipedia has its own notability standards, and its conflict of interest rules tell you not to write or edit your own article directly. Earn coverage first; let others write about you.
What is sameAs and where do I put it?
sameAs is a property in Organization structured data that lists URLs of your official profiles elsewhere, such as LinkedIn, YouTube, Crunchbase or your Wikidata item. It tells search engines these pages describe the same organization. Google suggests placing Organization markup on your home page or a single about page. You can list multiple sameAs URLs.
How do I claim my Google knowledge panel?
Search for your brand on Google. If a knowledge panel appears, click Claim this knowledge panel and sign in to one of the official sites or profiles Google already links to the entity, such as YouTube or Search Console. Google says not every panel can be claimed. Local businesses manage their panel through Google Business Profile instead.
Does schema markup make AI mention my brand?
Not by itself. Google says Organization markup helps it understand your organization and tell it apart from others, which is useful groundwork. But AI answers draw mostly on what other sites say about you. Schema makes your identity clear; mentions on independent, indexed sites give engines something to say. You need both, and neither guarantees a mention.
What is NAP consistency and does it matter outside local SEO?
NAP means name, address and phone number. Local SEO practice is to keep them identical everywhere, and experts still rate that consistency as a local ranking signal, though that is opinion research, not Google confirmation. The same idea applies to any brand: keep your name, description, category, founding year and locations identical across your site, profiles and coverage.
