What is a Canonical URL?

Canonical URLs

canonical URL is the URL of the page that Google thinks is most representative from a set of duplicate pages on your site.

If you have two URLs that serve very similar content, consider canonicalizing them, using one of these methods:

  1. By setting a rel=canonical HTTP header response, if you want to maintain slightly different versions for some visitors, e.g. a printer-friendly page.
  2. In your sitemap (however, while all pages listed in a sitemap are suggested as canonicals; Google will decide which pages (if any) pages are duplicates).
  3. By using 301 redirects if there’s no real reason to maintain the duplicate.

Pre-launch and immediately post launch, ensure the following:

  1. Content is available at a single, canonicalized URL.
  2. Google-selected canonical matches user-selected canonical. This can be determined once Google fully indexes a website. 
  3. No canonical/indexation mixed signal errors. This can be found in Google Search Console.
