Free Toxic Backlink Checker

Our toxic backlink checker scores each of your backlinks for spam risk and helps you build a disavow file from the ones you decide are harmful. It pulls your referring domains from DataForSEO, attaches the per-link spam score (0-100) to every one, and sorts the worst offenders to the top. You review the high-risk links, select the ones worth disavowing, and download a Google-Search-Console-ready disavow.txt, all without an account.

The workflow is one step plus your judgment. Enter your domain. We fetch your top referring domains, score and band each link as Low, Medium, or High risk, and pre-check the high-risk rows for you. Edit the selection, tweak the disavow list if you want, and download the file. Nothing is auto-disavowed, you decide what goes in. Results are cached for 24 hours.

For Site Owners

Our tool turns a vague worry into a concrete list. Use it to:

• Spot the backlinks with the highest spam scores at a glance
• Select only the links you judge harmful, not a blanket sweep
• Download a disavow.txt ready to upload to Search Console

For Agencies

Our tool gives you a defensible cleanup process for clients. Use it to:

• Show a client which links carry real spam-score risk
• Document exactly what you disavowed and why
• Keep a CSV record of the full scored profile

Why Use Our Toxic Backlink Checker

• Real per-link scores: Every backlink carries DataForSEO's own per-link spam score, so you triage on data rather than a single domain-wide number.
• You stay in control: We pre-check the high-risk rows as a starting point, but you choose what to disavow. The disavow file only ever contains what you selected.
• Honest about the stakes: A spam score is a heuristic, not a Google penalty verdict, and disavowing good links can hurt rankings. We say so plainly and never disavow anything for you.
