Domain Authority

Domain Authority (DA) is a score developed by Moz that predicts a website's likelihood of ranking in search engine results. It's calculated based on the quantity, quality, and diversity of backlinks pointing to a domain, scored on a logarithmic scale from 0 to 100 (meaning it gets progressively harder to improve as you go higher).

While no ad network officially lists DA as a requirement, higher DA correlates strongly with the signals networks do care about: organic traffic quality, content credibility, and site longevity. Publishers with DA 30+ have significantly higher approval rates at premium networks than those with DA under 15.
