What you get

  1. 01

    Two spam scores

    One for the links pointing at the domain, one for the domain itself. They answer different questions and often disagree.

  2. 02

    The worst offenders

    The 10 spammiest referring domains, with the linking page, anchor text, and whether the link is follow or nofollow.

  3. 03

    Put the score in context

    See spam scores alongside referring domains and domain rank. Use a high score as a reason to review the links, not as proof of a penalty.

FAQ

What does the spam score actually measure?

DataForSEO scores a link profile from 0 to 100 by looking at signals its index associates with low-quality sites — thin or duplicated content, link networks, unusual outbound link patterns. Higher means more of those signals. It is not a Google penalty score; Google publishes no such number.

Should I disavow the links you show?

Usually not. Google ignores most low-quality links on its own, and disavowing good links does real damage. Treat a high score as a reason to look, not as a to-do list.

How many links does the free check show?

The 10 highest-spam referring domains, one link each. OpenSEO lets you filter the full backlink profile by spam score and see how much of the profile is affected.

Where does the data come from?

DataForSEO's backlink index, cached for 24 hours per domain. It's the same data OpenSEO uses for backlink research.
