Easily check the canonical tag of a page

A lightweight and extremely easy Chrome extension that tells you the canonical source of any URL you are on. No more combing through the source code to understand if/when canonical tags point to a new destination. This extension does all the heavy lifting for you. This extension will display one of three values. GREEN (self canonical) AMBER (Canonicalized) or RED (error) Below are the conditions Inspect Canonical tests for, in the order it tests for them: RED: 1. Page contains noindex robots meta Message: "Page contains robots 'noindex' tag. Canonical tags are ignored. Click to view source" 2. No canonical in head but there is one elsewhere Message: "Canonical tag exists but not in <head>. Click to view source" 3. No canonical tag at all Message: "Page has no canonical tag. Click to view source" 4. More than one canonical tag on page Message: "Multiple ([X]) canonical tags found. Click to view source" 5. Canonical exists but is missing the href attribute Message: "Canonical tag is missing 'href' attribute. Click to view source" - This is an unlikely case but still something I wanted to check for AMBER: 6. Canonical present but differs to current URL Message: "Canonical tag points to another URL. Click to visit URL: [URL]" GREEN: 7. Canonical is present and correct Message: "Canonical tag points to current URL. Click to view source" So that's 7 hurdles to jump through to get a green status.

Hey Jim, can you email me details on the issue? The plugin has been used by thousands and I’ve never heard of it simply not working before. Thanks, Nick. (Nick AT

I like the tool, but it would be great if you can add 1 more option. When the button is amber, if I click on the icon, it opens the canonical link in a new tab and I would love it to open in the same tab! :)

When switching between tabs and opening a lot in new tabs, the addon does not work because it shows green icon but URL in adressbar is not matching the canonical tag. And when clicking it opens the wrong URL. So I have to look for another addon. @developer If you bugfix this please tell me, so I review it again.
