Enter a URL
Regardless of whether "www" is present in the domain name, a www redirect checker is a tool that determines if a website directs users to the same URL. This is how it operates:
A www redirect checker will visit a website with and without the "www" prefix when you enter its URL to test if both versions resolve to the same final URL. If they don't, search engines will treat the "www" and non-"www" versions of the website as different sites due to a canonicalization problem.
