Search engines compare page content and URL signals to understand which version best matches a search. A canonical tag can identify the preferred URL, while redirects can remove unnecessary alternatives. Internal links, sitemaps and consistent URL settings also help search engines find the intended page.

How Technical SEO checks it

A technical SEO review groups similar URLs and checks how each version is crawled, indexed and linked. The review then separates useful variations from pages that should point to one main version.
