Read the canonical URL declared by a page. Canonical declarations are hints; this tool cannot identify the canonical selected by Google or another search engine.
Inspect HTML canonical declarations and Link header evidence. Find missing, multiple or different canonical targets with this free checker.
HTML declarations are resolved against the document’s base URL. The Link header is shown as raw evidence and is not fully interpreted. Canonical destinations are not crawled; JavaScript changes and search-engine selections are outside this check.

This declaration suggests /product as the preferred URL for the content. It does not prove a search engine selected it.
