Duplicate URL Detector
Detect duplicate URLs in a list and suggest canonical versions for SEO.
https://example.com/blog/my-post https://example.com/pricing https://example.com/contact
The same page reachable at four different-looking URLs, with and without www, with and without a trailing slash, over http instead of https, reads as four separate pages to a search engine unless something explicitly tells it otherwise, which is exactly the kind of duplicate content problem that quietly splits ranking signal across variants that were never meant to compete with each other. This tool scans a list of URLs for exactly that pattern, duplicate or near-duplicate variants of what's really the same page, and suggests which version should actually serve as the canonical one.

Useful for catching duplicate URL variants before they split SEO value across pages that should be treated as one, cleaning up a sitemap or a URL list that's accumulated both http and https versions of the same pages, or confirming a canonical URL structure is actually being followed consistently across a site.
