Check which URL this page says is the real one.

Find the rel=canonical tag, resolve relative URLs and flag missing or multiple canonical declarations.

Free to run. No account. Public URL checks are fetched only to return the result.

The annoying bit

You told Google which page is the real one. Hopefully you told it the right one.

Canonicals are invisible until they are wrong. A copied template or old domain can quietly point an otherwise healthy page somewhere else.

Worth knowing

For a normal unique page, a clean self-referencing canonical is usually easiest to maintain. Use cross-page canonicals deliberately.

Next little job

Titles, redirects, canonicals, robots, sitemaps and schema all live in the same focused category.
