Free Spam Score Checker

Assess any site's trust and link-profile health in seconds. A second-dimension quality signal that pairs with Domain Rating (DR) — because a high authority score alone doesn't mean a domain is clean.

What is Spam Score?

Spam Score is a trust signal — a shorthand for "how sketchy does this site's backlink profile look?" Moz popularized the 0–17 scale, where higher means riskier. Common flags include an unusually high ratio of anchor-text-matching links, links from expired or thin-content domains, private blog networks (PBNs), and link-exchange footprints.

It's a complement to authority scores like Domain Rating (DR), not a replacement. A site can score DR 60 and still be spammy if most of its authority comes from low-trust sources.

How to read the score

  • 0–4 — low risk. Backlink profile looks natural.
  • 5–7 — medium risk. A few suspicious signals; worth a manual review.
  • 8–17 — high risk. Strong PBN, link-farm, or manipulation footprints.

DR + Spam Score together

Use Domain Rating to answer "how strong is this site?" and Spam Score to answer "how trustworthy is that strength?" A guest post on a DR 70 site with a Spam Score of 2 is a great link. The same DR 70 with a Spam Score of 12 is a liability.
