Canonical Tag Auditor: Canonical Tag Auditor

Hi Product Hunt 👋

We’re Bracketworks, a design and dev agency in Dubai. In our site audits, one problem comes up all the time: the canonical tag says one URL, but the redirects, robots.txt or the http/https and www/non-www versions say something different. Google looks at all of these signals together, so a correct-looking tag can still be ignored.

Most checkers only read the tag. So we built Canonical Tag Auditor. Paste one URL, and it checks the canonical tag, follows the redirects, reads robots.txt and tests every version of the address to see if they all point to the same page. It also tells you what to fix first: redirects, then the tag.

One known limit: it reads the HTML before JavaScript runs, so it can’t see a canonical tag that a script adds.

Feedback that would help us most:

Is the result clear? Do you know what to fix after one run?
Did it give a wrong result on a site you know well?
Should we add JavaScript rendering, or a check for more than one page at a time?

We read every comment.
