Warning canonical-missing

Homepage declares a canonical URL

What this check means

Checks for a <link rel="canonical"> on your homepage.

Why it matters

Most sites are reachable at several addresses — with and without www, with tracking parameters, with and without a trailing slash. The canonical tag says which one is the real address, so a system citing you links to a URL that will still resolve in a year.

How we detect it

We read <link rel="canonical"> from the parsed homepage and require a non-empty, absolute URL.

How to fix it

Add <link rel="canonical" href="https://yourdomain.com/"> to your document head, using the absolute preferred URL.

Check whether this applies to your site.
