Backlink List Deduplicator
A backlink list deduplicator removes repeated links from a list. Paste URLs or domains and choose how to compare them: exact text, normalised URL or one entry per domain. This free tool keeps the first copy of each, shows how many duplicates it removed and lets you download the clean list.

What is a backlink list deduplicator and when should you use it?
Link lists from different exports often repeat the same page, sometimes with small differences such as a fragment or a capital letter. Removing those repeats gives you a shorter list to review. Choose "One per domain" when you plan to review whole websites rather than single pages, and use the URL to Domain Extractor if you only need the domain names. Deduplicating backlink lists prevents duplicate processing and redundant outreach. After removing duplicate entries, extract distinct hostnames with the URL to Domain Extractor and consolidate subdomains with the Subdomain to Root Domain utility. If your list includes disavow candidates, build a Google-compliant file using the Disavow File Generator, check syntax via the Disavow File Validator, and clean directives with the Disavow File Cleaner. To assess link risk, audit your profile with the Toxic Backlink Checker, analyze TLD profiles using the Backlink TLD Distribution tool, inspect anchor distributions via the Anchor Text Distribution Analyzer, clean GSC exports with the Search Console Links CSV Cleaner, and compare list changes using List Compare.
