Canonical tags are used to avoid possible duplicate issues when unique content is accessible from different URLs. Access your page's source code to verify if pages reported by our site auditor have missing canonical tags.
How to find missing canonical tags on your website
Navigate to the SEO --> Site Auditor dashboard module. Click "Missing Canonical Tag" to see more information about which URLs have been reported with this warning.
The dashboard will show you a list of pages with missing canonical tags. Click the page URL (colored in grey) to open it in a new tab.
Once the new page has opened, right-click and select "View Page Source".
A new tab will open showing your page's source code. Press Control+F to open the search bar and search for rel="canonical".
If your browser's search tool gives back 0 results, that means that your page has a missing canonical tag.
If you've found a canonical tag on your page but it's still being flagged as missing by our site auditor, reach out to our customer support team for assistance.
