Do Wikipedia and Wikidata shape what AI says about you?

What are the key facts about Wikipedia, Wikidata and AI?

Why does AI lean on Wikipedia?

Because Wikipedia is one of the biggest free, sourced, regularly updated collections of facts on the internet, and nearly every AI model learned from it.

The Wikimedia Foundation, which runs Wikipedia, put it plainly in 2023: "every LLM is trained on Wikipedia content." It added that Wikipedia is "almost always the largest source of training data" in those sets. Wikimedia Foundation In November 2025 it called Wikipedia one of the "highest-quality datasets in the world for training AI." Wikimedia Foundation

The big AI and search companies also pay for a direct feed. Wikimedia Enterprise sells APIs for Wikipedia and Wikidata, and its site lists Amazon, Google, Microsoft, Meta, Perplexity and Mistral AI under "Trusted by companies that build AI and search." Wikimedia Enterprise

Google's Knowledge Graph, the fact database behind the info boxes in Google results, has roots in Wikipedia too. When Google launched it in 2012, it named Freebase, Wikipedia and the CIA World Factbook as public sources. Google Today Google's help page says only that Knowledge Graph facts come from "a variety of sources," including licensed data and suggestions from content owners. Google

How often do AI answers cite Wikipedia?

Often, but less than they used to in ChatGPT. No AI company publishes these numbers, so they come from outside studies.

• ChatGPT: Semrush tracked 230,000 prompts from July to October 2025. Wikipedia appeared in roughly 55% of ChatGPT responses before mid-September, then under 20% after. It was still one of ChatGPT's two most-cited domains. Semrush
• Google AI Mode: Semrush measured Wikipedia at about 3% of responses in the same period. Semrush Ahrefs ranked en.wikipedia.org #6 in the US in September 2026, with a 4.0% share. Ahrefs
• Perplexity: around 0.8% of responses, per Semrush. Semrush

What is Wikidata, and why does it matter for my business?

Wikidata is Wikipedia's sister site for facts in a structured form that machines can read. It calls itself a "free, collaborative, multilingual, secondary knowledge base, collecting structured data." Wikidata

Each thing gets an item with an ID (a Q-number), and each fact is a statement: founded in, headquarters, official website, and so on. Statements can carry references. All of it is released under CC0, which means anyone, including AI and search companies, can reuse it without asking. Wikidata

That's why it matters for entities. An entity is a specific, identifiable thing, like your company, as opposed to a phrase. When an AI or search engine is trying to work out whether "Summit Dental" in Denver is the same business as "Summit Dental" in Utah, a clean set of facts with an official website attached helps it tell them apart.

Wikidata's bar is lower than Wikipedia's but real. An item must meet one of three tests. The one most businesses rely on is being "a clearly identifiable conceptual or material entity" that "can be described using serious and publicly available references." Wikidata Its help page says most statements "should be verifiable," backed by sources such as newspapers or reference books. Wikidata

Should I write a Wikipedia article about my own business?

No, for most small businesses. Wikipedia's rules make it hard, and the article usually doesn't survive.

First, notability. Wikipedia only covers a topic once it has "significant coverage in reliable sources that are independent of the subject." Your website, ads and press releases don't count. Wikipedia Most local businesses don't have that coverage yet, and no amount of writing can create it.

Second, conflict of interest. Wikipedia says editing articles about "your organization, your clients, your employers, or your competitors is strongly discouraged." Wikipedia Its guideline says COI editors should propose changes on the talk page and send new articles through Articles for Creation, not publish them directly. Wikipedia Wikipedia also says it is not a place for "advertising, marketing, publicity, or public relations." Wikipedia

Third, paid editing has legal rules. The Wikimedia Terms of Use require anyone paid to contribute to disclose "each and any employer, client, intended beneficiary and affiliation." That's done on a user page, a talk page or in the edit summary. Wikimedia Foundation Wikipedia adds that editors who don't disclose can be blocked. Wikipedia The requirement covers "any contribution to any Wikimedia Projects," so it applies to Wikidata too. Wikimedia Meta-Wiki

What can I do instead?

Work on the things Wikipedia and AI both look for: independent coverage and clear, sourced facts.

• Earn real press. Local news, trade publications and industry awards are the "independent" sources Wikipedia's notability rule asks for. They also help AI directly, because AI engines read news sites. Wikipedia
• Fix an existing article the right way. If you already have a Wikipedia article with wrong facts, post on its talk page, say who you are, and use the {{edit COI}} template so a volunteer reviews it. Bring an independent source for each fix. Wikipedia
• Check Wikidata. Search for your business. If an item exists, its official website, location and founding date should be right and referenced. Anyone editing it for a business they work for, or are paid by, must disclose that. Wikidata Wikimedia Foundation
• Link your profiles with sameAs. Google's Organization markup has a sameAs property for "a page on another website with additional information about your organization," like a social or review profile. Google Google doesn't name Wikidata there. Our advice: if a Wikidata item or Wikipedia article about you exists, list it in sameAs too.

For transparency: AI Syndicate edits Wikidata as a disclosed paid editor, under the account "Aisyndicate." We name the paying brand in edit summaries and don't create new items under that account. Our Wikidata disclosure has the details. We don't create Wikipedia articles.

How do I get Wikipedia and Wikidata working for me honestly?

This is our advice. It is built on the Wikipedia and Wikimedia rules linked above.

1. Search first. Look up your business on Wikipedia and Wikidata. Note what exists, what's wrong and what's missing.
2. Be honest about notability. Count the independent articles that cover your business in depth. Directory listings and your own press releases don't count. If you have none, a Wikipedia article isn't the next step.
3. Earn coverage before chasing an article. Pitch a local reporter a real story, enter industry awards, or get quoted as an expert. That coverage helps AI whether or not Wikipedia ever follows.
4. Correct errors through the talk page. Disclose who you are, use {{edit COI}}, cite an independent source, and let a volunteer decide.
5. Keep Wikidata facts sourced and disclosed. Each fact should have a reference. If you or someone you pay makes the edit, disclose it as the Terms of Use require.
6. Make your own site match. Your name, address, phone, founding year and services should read the same on your site as anywhere else. Add Organization schema with sameAs links to your real profiles.
7. Never hire a hidden writer. Undisclosed paid editing breaks the Terms of Use and can get accounts blocked and articles deleted.

What should be on my Wikipedia and Wikidata checklist?

How do I check whether AI is using Wikipedia to describe me?

Ask ChatGPT, Google AI Mode and Perplexity "What is [your business]?" and look at the sources each answer lists. If Wikipedia or Wikidata shows up, check that what they say is right. If it doesn't, see which sites the AI uses instead.

Our Prompt Simulator runs one question across 12 engines at once and shows which sources each one cites. If an AI has your facts wrong, AI is wrong about your business covers how to correct the record.
