Backlink Metrics Explained
Referring Domains
Number of unique domains linking to your site. Quality over quantity — 100 links from 100 different domains is far more valuable than 100 links from 1 domain.
Domain Authority (DA)
Moz's 1-100 score predicting how well a domain ranks in search engines. Higher is better, but compare it to competitor scores rather than in isolation.
Domain Rating (DR)
Ahrefs' version of authority score. Reflects the strength of a website's backlink profile relative to all other sites in their index.
Anchor Text
The clickable text in a hyperlink. Diversify your anchor text profile — too many exact-match anchors can look manipulative to Google.
Follow vs Nofollow
Follow links pass ranking authority ('link juice') to your site. Nofollow links don't directly pass authority but can still drive referral traffic.
Toxic Score
Estimates whether a backlink could harm your rankings. Links from spammy or irrelevant sites can be disavowed via Google Search Console.
