Verify your rel="canonical" tag points to the right URL. A wrong or missing canonical tells Google to index the wrong page — or splits ranking signals across duplicates.
The canonical tag is how you tell search engines which URL is the "real" one when the same content lives at multiple addresses. Get it wrong — point it at the wrong page, another domain, or a relative path — and you can deindex pages you wanted ranked or split ranking signals across duplicates. This tool reads your canonical tag, resolves it to an absolute URL, and confirms whether it correctly references the page itself.
