Canonical URL notes

What is a canonical link for?

A canonical link tells search engines which URL is the preferred version of a page. This is especially useful when the same content can be reached through several technical variants, for example with or without www, with tracking parameters or through different internal links.

  • Use an absolute URL with https:// whenever possible.
  • Remove tracking parameters such as utm_source, fbclid or gclid.
  • Usually set exactly one canonical URL per page.
  • Use the URL that should be indexed permanently.
