Prevent duplicate-content problems in seconds. This free canonical tag generator creates the rel=canonical link tag that tells search engines which version of a page is the original, consolidating ranking signals to the URL you choose.
How to use the canonical tag generator
Enter the preferred (canonical) URL for the page and copy the generated tag into the <head>. When the same or very similar content is reachable at multiple URLs — for example with tracking parameters or print versions — a canonical tag points search engines to the one you want ranked.
Frequently asked questions
What is a canonical tag?
A canonical tag (rel=canonical) is an HTML link element that names the preferred URL for a piece of content. It helps search engines consolidate duplicate or near-duplicate pages into a single ranking URL.
Should a page canonicalize to itself?
Yes. Self-referencing canonicals are a best practice. Each page should include a canonical tag pointing to its own clean, preferred URL.
Does a canonical tag guarantee which URL ranks?
No. Canonical tags are a strong hint, not a directive. Google usually respects them but may choose a different canonical if other signals disagree.
