Canonical Tag Generator
Generate a canonical tag that tells search engines which URL is the master version of a page.
Pointing to the one true URL
The same content is often reachable at several URLs — with and without a trailing slash, with tracking parameters, printer versions, and so on — and search engines can treat those as separate, competing duplicate pages. A canonical tag names the single preferred URL, consolidating the ranking signals onto it. This generates the correct tag for the master URL you choose.
Enter the canonical URL and the tag is produced for the page's head.
Where canonicals earn their keep
They are essential wherever duplication creeps in: URL parameters from filters and tracking, syndicated content that also appears elsewhere, and near-identical pages you want to consolidate. The canonical should point to a single, consistent, absolute URL, and a page can even declare itself canonical to lock its own preferred form. Used well, canonical tags stop your own pages competing with each other and make sure the version you care about is the one that ranks.
Questions & answers
What does a canonical tag do?
It tells search engines which URL is the master version of a page, consolidating ranking signals when the same content lives at several addresses.
When do I need one?
Whenever content is reachable at multiple URLs — tracking parameters, filters, printer versions, or syndicated copies.
Is anything uploaded?
No. The tag is generated in your browser.
