What is a canonical tag?

A canonical tag is an HTML element that tells search engines which version of a page is the primary version when duplicate content exists. It looks like: <link rel="canonical" href="URL">

Where should canonical tags be placed?

Canonical tags must be placed in the <head> section of your HTML document, not in the body.

Should I use absolute or relative URLs?

Google strongly recommends using absolute URLs (https://example.com/page) in canonical tags to avoid any ambiguity.

Can I have multiple canonical tags?

No, each page should have only one canonical tag. Multiple tags can confuse search engines and may be ignored.

What happens if I don't have a canonical tag?

Without canonical tags, search engines may see duplicate content issues, split page authority, or index the wrong version of your pages.

Should every page have a canonical tag?

Yes, it's best practice for every page to have a canonical tag, even if it's self-referencing (points to itself).
