Helpful questions

What is a canonical URL?

A canonical URL is the preferred URL that search engines should treat as the main version of a page when duplicate or similar URL versions exist.

Where should I place a canonical tag?

Place one canonical link element inside the HTML head of the page, or use an HTTP Link header for file types or advanced server workflows.

Should canonical URLs include UTM parameters?

Usually no. Tracking parameters are normally removed because they create duplicate URL variants that should point back to the clean page.

Should I force HTTPS in canonical URLs?

Yes when the page is available over HTTPS. Canonicals should usually point to the secure version that users and search engines should prefer.
