Canonical Checker

Status: Coming soon. This tool is in active development and does not run yet — this page describes what it will do once it is live, without showing any placeholder or fake results.

What this tool will do

Once live, the Canonical Checker will verify what canonical URL a page declares, and flag common issues like a canonical pointing to a different page than expected. It will run in your browser as a free, single-purpose utility — no account or payment required.

Who this is for

This tool is being built for anyone troubleshooting duplicate content or unexpected pages being excluded from search results.

In the meantime

The concepts behind this tool are already covered in our written guides — see the related guides below for the manual version of what this tool will eventually automate. This page will be updated (and set to index once functional) as soon as the tool is ready.
