Duplicate URL finder

Group a list of addresses by the page they really are, and see which need a canonical.

These generators run in your browser, so they need JavaScript enabled. Everything explained on this page is still readable without it.

Nothing is sent anywhere. Reload to clear.

These are all one page to you and four pages to Google

A trailing slash, http against https, www against bare, a tracking parameter: each makes a different address, and Google may index any of them. Pick one, declare it as the canonical on all of them, and the ranking signals stop being split.

Pulled proof · Grouped by the page they really are
  • Paste a few addresses to group them.

Addresses that resolve to the same page will be grouped above.
