DA vs DR: Which Metric Should Actually Drive Your Shortlist?
Two vendors, two scales, two different answers about the same domain. Understanding what each one measures stops you overpaying for the wrong sites.
They are estimates of different things
Domain Authority and Domain Rating are both third-party approximations of link strength, produced by different companies crawling different indexes with different models. Neither is used by any search engine. They are useful as comparative shorthand, and misleading when treated as absolute truth.
Domain Rating leans heavily on the volume and strength of referring domains. Domain Authority incorporates a broader feature set and is calibrated to predict ranking ability. This is why the two frequently disagree by ten or more points on the same domain.
When they diverge, ask why
A large gap is information, not noise. A site with DR 70 and DA 30 has usually accumulated a lot of links that one crawler values highly and the other discounts — often a sign of link-scheme participation.
The reverse pattern, high DA with lower DR, is more often a site with fewer but genuinely editorial links. That is frequently the better placement, and it is usually cheaper because the headline number looks less impressive.
What to filter on instead
Use authority scores to narrow a large list quickly, then decide on relevance and traffic. A DA 25 publication read by exactly your buyers will outperform a DA 55 general blog almost every time.
In practice a sensible filter is a floor rather than a target: DA above 20, spam score under 5%, traffic above a few thousand, and topical relevance you can verify by reading two articles.
