What the score highlights
Use the score to find domains or pages that need a closer review. A lower score suggests fewer spam patterns, while a higher score suggests more.
Read the spam score
The score runs from 0 to 100 and comes with a band, using DataForSEO's own cut-offs.
| Score | What it means |
|---|---|
| 0 to 30, low | Normal for most real sites. Nothing to act on. |
| 31 to 60, medium | Open the site and look. Often a thin or neglected site, sometimes worse. |
| 61 to 100, high | Many spam patterns. Look hard before you link to it or ask it for a link. |
"N/A" means DataForSEO has no score for that target, usually because it has not crawled the site. That is not the same as a score of zero.
What the spam score measures
DataForSEO checks each page it has crawled against 18 signals that spam sites tend to share, then averages the pages for a domain score. The signals are about the site's own pages: things such as a very short or very long domain name, a domain full of numbers, no contact information, pages served over plain HTTP, and pages with far more outgoing links than internal ones.
So the score describes the site, not the links pointing to it. A good site with a few junk links aimed at it can still score low.
When a spam score matters
The score is a quick filter for link work. Before you chase a link from a site, or wonder whether a link to you is a problem, it tells you which sites deserve a closer look. Google's disavow guidance says most sites never need to disavow links, so a handful of spammy links pointing at you is usually not worth worrying about.
It matters more when you are about to buy a domain, accept a guest post or place content on a site. There a high score is a good reason to stop and check.
Check the site behind a high score
- Does it have real pages a person would read, or mostly ads and outgoing links?
- Can you find who runs it and how to contact them?
- Does it rank for anything? Run it through the website traffic checker. A site with links but no search traffic is a warning sign.
- How strong are its own links? The Domain Rating checker shows that side.
Spam scores from different checkers use different signals, so compare sites with one checker only.
Review link prospects with your AI agent
Checking one site at a time gets slow on a list of fifty prospects. With SEO Skill your agent can pull the domains linking to a competitor with seo research and your own DataForSEO or Ahrefs key. Ahrefs rows carry a Domain Rating already, and with DataForSEO the first 25 domains get one free. Your agent can then sort the list and open the sites worth a human look. Ask:
List the referring domains for competitor.example, sort them by Domain Rating, and flag any I should check by handAdd the hosted MCP server to your agent and sign in with Google:
