Spam Score Checker
Estimate what share of a domain's backlinks look spammy — paid-link-seller anchor text, or very-low-authority referring domains.
Free, no signup — while today's shared lookup capacity is available.
This is not an official metric (DataForSEO doesn't publish one, and this isn't Moz's Spam Score). It's a transparent heuristic computed from a sample of this domain's real backlinks — useful as a signal to investigate further, not a verdict.
How this score is calculated
This tool pulls a real sample of a domain's backlinks and flags ones matching known spam signals — anchor text like "buy backlinks" or "cheap SEO," and links from very low-authority, likely-new domains. It's a deterministic check against a fixed list of patterns, not a guess or an AI judgment call.
Why spammy backlinks matter
A backlink profile full of low-quality, obviously purchased links can drag down how much a search engine trusts a domain overall, even if some of its other links are genuinely earned. This matters both for auditing your own site's link profile and for vetting a domain you're considering linking to, buying, or partnering with.
What a flag does and doesn't mean
A flagged link is a candidate for a closer look, not automatic proof of a problem — a genuinely new, legitimate site can also show a low authority score simply because it hasn't been around long. Every flag here is meant for human review, the same way Winking Toad's own compliance checks work: surface what's worth looking at, don't assume the worst automatically.
What to do next
If a flagged link is actually spam and you didn't build it yourself, Google's disavow tool lets you tell Google to ignore it when evaluating your site. If you're vetting a domain before linking to it, a spam score built mostly from a handful of clearly purchased-looking links is a real reason for caution.
