Your homepage links to your Wikipedia article so AI can find authoritative facts
If you have a Wikipedia article, does your homepage tell AI systems where to find it?
What this signal tests
We check whether your homepage's identity card links out to your Wikipedia article (if you have one). Wikipedia is one of the most heavily-weighted sources in AI training data, and a working link tells assistants "the article you have already read about us applies to this exact website." The article must resolve to a real page, not a deleted entry or a disambiguation list.
Why it matters for your visibility in AI
AI assistants quote Wikipedia constantly. Large language models are trained on it, AI search products cite it, and consumer assistants repeat its facts almost verbatim. If your organization has a Wikipedia article, linking to it from your homepage anchors your domain to the body of text the AI already knows about you. The consequence of missing this link is real. Imagine a user asks "what are the recent products from Globex?" If Globex has a Wikipedia article but no link from globex.com, an AI assistant may struggle to confirm which Globex the user means and either pick the wrong one or hedge so heavily the answer becomes useless. A single sameAs link removes that ambiguity.

How we test it
We parse your Organization JSON-LD and inspect the sameAs array for URLs matching the Wikipedia article pattern (any language subdomain followed by /wiki/ and an article slug). For each match we fetch the URL and check that it returns a successful response, the page is a regular article, and not a disambiguation page (which lists multiple entities with similar names). If no match exists, or every Wikipedia link is broken, this signal fails.
Show technical detection method
Match ^https?://[a-z\-]+\.wikipedia\.org/wiki/.+; fetch 200 (not disambig).
If your site fails: how to fix it
- Check whether your organization already has a Wikipedia article by searching en.wikipedia.org for your exact name; if so, copy the article URL.
- If you do not have an article, do not create one yourself. Wikipedia's conflict-of-interest rules will get a self-authored entry deleted, which damages your reputation in the AI training corpus.
- If an article does exist, add its full URL to the sameAs array of your Organization JSON-LD on the homepage.
- If your article points to a disambiguation page (multiple entries with the same name), use the more specific article URL, for example 'Acme_Corp_(consulting_firm)' instead of just 'Acme'.
- If you do not yet meet Wikipedia's notability standard (significant independent coverage), focus first on Wikidata, which has a lower bar and delivers most of the same AI-recognition benefit.

Frequently asked questions
Do I need to be on Wikipedia to be recognized by AI?
Not absolutely, but Wikipedia inclusion meaningfully boosts how confidently AI systems cite you. If you are not yet notable enough for Wikipedia, a Wikidata entry (which has a lower bar) covers most of the same ground and is detected by the next signal.
Can I write my own Wikipedia article?
Strongly discouraged. Wikipedia's conflict-of-interest policy forbids paid or self-promotional editing, and articles written by their subjects are typically deleted or rewritten. The better path is to earn third-party coverage and let independent editors create the article.
What if my Wikipedia article has errors?
You can request corrections on the article's talk page, citing reliable sources. Do not edit the article directly if you are affiliated with the subject. AI assistants will repeat whatever Wikipedia says, so accuracy on Wikipedia is worth the patient process.
Does linking to a foreign-language Wikipedia article count?
Yes. The pattern matches any language subdomain (de.wikipedia.org, ja.wikipedia.org, etc.). If your primary audience is non-English, linking to your native-language article is reasonable; linking to multiple language editions in sameAs is even better.
