Check that the canonical link names the right host on WordPress
Why it matters
The canonical link names a different host of your domain than the one the page was served from, for example a staging or old subdomain. If that is not deliberate, search engines index the other host instead of this one.
The fix
- Open Settings, General and check that WordPress Address and Site Address use the host you want visitors to see. A staging or old subdomain there is copied into the canonical.
- Also check the canonical field of your SEO plugin, then clear caches.
