  • This is a heuristic based on domain signals, not a live crawl. Runs entirely in your browser.

Free Toxic Backlink Checker (Spam-Score Estimator)

Estimate the spam risk of your backlinks in seconds. Paste referring domains or backlink URLs and get a heuristic spam score (0–100) for each, based on signals like spam-prone TLDs, keyword-stuffed domains, IP hosts, and excessive hyphens — so you can decide what to disavow. Free, no sign-up, runs in your browser.

What this tool does

Not every backlink helps you — links from spammy, low-quality sites can drag down your profile. This tool scores each domain you paste for spam-risk signals and sorts the riskiest to the top, giving you a fast shortlist of candidates to investigate or disavow. It turns a long, unreadable backlink list into a prioritised risk report.

How to use it

It is instant:

  • Paste your referring domains or backlink URLs, one per line.
  • Click Analyze to score each domain.
  • Review the high-risk domains and their signals.
  • Copy the high-risk list straight into a disavow file.

What signals it checks

The score combines several well-known spam indicators: <strong>spam-prone TLDs</strong> (like .xyz, .tk, .ml, .info), an <strong>IP address used as the host</strong>, <strong>keyword-stuffed or heavily hyphenated</strong> domain names, long digit runs, <strong>obvious spam keywords</strong> (casino, viagra, cheap backlinks, and similar), link-scheme wording, and unusually deep subdomains. Each signal adds to a 0–100 score, and domains are grouped into low, medium, and high risk.

It's a heuristic, not a verdict

This estimator looks only at the domain string, not at live link data, so treat the score as a triage aid rather than a final judgement. A legitimate site can occasionally use a cheap TLD, and a spam network can hide behind a clean-looking name. Always review high-risk domains yourself before disavowing — the tool's job is to surface the ones worth a closer look.

From risk score to action

Once you've confirmed a domain is genuinely harmful and you can't get the link removed at the source, add it to your disavow file. Copy the high-risk list here and paste it into our Disavow File Generator to produce a Google-ready disavow.txt. Keep your disavow list conservative — only include links you're confident are toxic.

Privacy

All scoring happens locally in your browser from the text you paste — your backlink list is never uploaded, logged, or stored. That keeps your audit private, which matters because your toxic-link list reveals which sites you consider harmful.

FAQ

Is this toxic backlink checker free?
Yes. It is completely free, runs in your browser, and needs no account or sign-up.
How is the spam score calculated?
It combines domain-based signals — spam-prone TLDs, IP hosts, keyword-stuffed or heavily hyphenated names, spam keywords, and link-scheme wording — into a 0–100 score, grouped into low, medium, and high risk.
Does it crawl the actual backlinks?
No. It analyses the domain string itself, so it's a fast heuristic triage tool rather than a live crawler. Always review high-risk domains manually before acting.
Should I disavow every high-risk domain?
No. Use the score to prioritise a manual review. Only disavow links you've confirmed are genuinely harmful and can't get removed at the source.
Where do I get my list of referring domains?
Export them from Google Search Console (Links report) or any backlink tool, then paste the domains here. Our Referring Domain Extractor can also turn a URL list into domains.
Is my backlink list uploaded anywhere?
No. Everything is processed locally in your browser, so your list never leaves your device.
How do I turn the results into a disavow file?
Copy the high-risk domains and paste them into our Disavow File Generator to create a Google-ready disavow.txt.
