Pages missing canonical link tag

A canonical tag is a line of HTML code that tells search engines which version of a page is the "official" one - preventing duplicate-content confusion when your page is accessible via multiple URLs (with or without www, trailing slashes, query parameters, etc.).

Why this matters

When search engines see the same content at multiple URLs without a canonical hint, they may treat the versions as duplicates and choose one themselves, which might not be the one you prefer. A canonical tag tells them which version to consolidate on, which can help avoid split signals.

How to fix it

Add a <link rel="canonical" href="[page URL]"> tag to every page. It must appear in the server-rendered HTML, not just injected by JavaScript. Your developer or CMS usually has a one-click setting for this.
