Add a canonical link to the homepage on WordPress

Why it matters

A canonical link names the one address you want search engines to treat as the real homepage, so versions with tracking parameters or without www do not compete with each other. Without it, search engines choose for you.

The fix

1. WordPress core prints a canonical link on single posts and pages, but not always on the homepage. An SEO plugin (such as Yoast SEO, Rank Math, All in One SEO or SEOPress) adds it everywhere; install one and check that its homepage setting does not override it with another address.
2. Check Settings, General that the WordPress Address and Site Address use the preferred version of your domain.
