FAQ & usage tips
Q:Is Domain Rank the same as Moz DA or Ahrefs DR?
No. It is DataForSEO's own 0–1000 link-strength score. It measures the same idea and is good for comparing sites, but the numbers do not convert.
Q:What does a high spam score mean?
A larger share of suspicious links point at the domain. Check carefully before buying an expired domain or trading links.
Q:Can I check a subdomain?
It checks the host you enter; enter the root domain for the whole site.
