How it happens
The model retrieves several pages, composes an answer from all of them, and lists sources at the end. The capacity may come from a retailer, the weight from a review, the name from your page — and your page is cited for all three. To a buyer, your link now vouches for a figure you never published.
How to check
For each fact in the answer:
- Find it on the cited page, word for word or number for number.
- If it is not there, note which other cited page says it.
- Record the model name, the date and the mismatch.
This is the difference between the "cited" and "fact matched" steps of the ladder (/learn/crawled-cited-and-used-are-different-things).
What reduces it
Stating the facts a buyer asks about plainly on your page, with units and limits, gives the model a primary source for the values it is attaching to your link. It does not guarantee the model will use them — the rules that keep a citation apart from use of a fact are at /evidence.
