FAQ
Straight answers on what the tools check and how a corporate email unlocks your site.
It names the page URL. Without it, crawlers may cite a variant with the wrong parameter or language.
Not for a single-language site. Absence is a warning, not a failure, when the canonical exists.
The email domain is the site that gets checked. The address is added to the MencionAI newsletter. Webmail such as Gmail and Outlook does not unlock the check.
Pass means the expected signal is present and readable. A warning is a partial or missing signal that does not fully block the page. Fail means the file or signal this check looks for is missing.
No. It reads the HTML, headers, and files a crawler receives on the first response. It does not open a browser and it does not call an AI model.
