Your homepage links to your Wikidata entry so AI knows exactly who you are
Do you point AI systems to your Wikidata record, the canonical identifier they trust most?
What this signal tests
We check whether your homepage's identity card includes a link to your Wikidata page. Wikidata is the open knowledge graph, the database AI systems use to know what your business actually is and which other businesses with similar names it is NOT. Each entity in Wikidata has a unique Q-number, like Q95 for Google.
Why it matters for your visibility in AI
Wikidata is the single highest-leverage entity signal on the open web. LLMs, Google's Knowledge Graph, Apple Intelligence, and academic citation systems all reconcile identities through Wikidata Q-numbers. Linking your site to your Q-number is like handing AI a passport with your photo on it. Without this link, an assistant asked "is Acme Consulting the same firm that advised the European Central Bank?" must guess from page content. The wrong Acme might get the credit, or the question may be refused. With the Wikidata link in place, AI systems can verify your identity in a single lookup and confidently cite your work, your founding team, and your relationships to other organizations.

How we test it
We parse the Organization JSON-LD block on your homepage and look at the sameAs array. We pattern-match each URL against wikidata.org/wiki/Q or wikidata.org/entity/Q followed by digits. For each match we make an HTTP request to confirm the Wikidata page actually exists and returns a successful response. If no Wikidata URL appears in sameAs, or every URL points to a deleted Q-number, the signal fails.
Show technical detection method
Scan sameAs for ^https?://(www\.)?wikidata\.org/(wiki|entity)/Q\d+$; resolve QID 200.
If your site fails: how to fix it
- Search Wikidata at wikidata.org for your organization name; if an entry already exists, copy its Q-number from the page URL.
- If no entry exists, create one by clicking 'Create a new item' on Wikidata; provide a label, description, and at least one reliable third-party source (a news article, government registry, or trade publication).
- Add core statements to the new item: instance of (business, nonprofit, etc.), official website, founded, and headquarters location.
- Once your Q-number is stable, add its full URL (https://www.wikidata.org/wiki/Q12345) to the sameAs array in your Organization JSON-LD.
- Deploy the updated homepage and re-run the scan to confirm the QID resolves and the signal passes.
- Avoid creating promotional or notability-thin Wikidata entries; the volunteer community will delete them and the signal will start failing again.

Frequently asked questions
What is Wikidata and why does it matter?
Wikidata is a free, openly editable database that assigns every real-world thing, people, companies, books, places, a unique Q-number. AI systems use it as the canonical reference for entity identity. If you do not exist in Wikidata, you may not exist as a distinct entity to many AI assistants.
Do I need to be famous to have a Wikidata entry?
No. Wikidata's notability bar is much lower than Wikipedia's. Any organization with verifiable existence (registered company, listed nonprofit, named author with published work) is eligible. You still need at least one independent reliable source to back up basic claims.
Can I edit my own Wikidata entry?
Yes, but disclose any conflict of interest on your user page and stick to verifiable, sourced facts. Promotional language, unsourced claims, or marketing copy will be reverted by other editors and may get the entry deleted.
How long until AI systems pick up the link?
Google's Knowledge Graph typically refreshes within days to weeks. LLM training corpora update on much slower cycles (months to years), but AI search products that read the live web, ChatGPT Search, Perplexity, Claude with tools, will reflect the new linkage on their next crawl.
