What does this tool do?
The SERPInsight Bulk Canonical Checker analyzes up to 50 URLs simultaneously to verify their canonicalization status. It crawls each URL, follows any redirects to find the final destination, and checks for the presence of the <link rel="canonical"> tag.
Correct canonicalization is critical for preventing duplicate content issues. This tool ensures that your pages are explicitly telling Google which version of the URL is the "master" copy that should be indexed.
