Methodology

How We Calculate Domain Authority Score

Our Domain Authority Score is a simple 0-100 rating derived from open link-graph data. It is not Moz Domain Authority and is not affiliated with Moz.

Formula

We fetch OpenPageRank's current score for the normalized registered domain, then calculate:

displayed score = Math.round(open_page_rank * 10)

How To Use It

Treat the score as a quick comparison signal. It is most useful when paired with referring domains, global rank, topical relevance, organic traffic, and a manual review of link quality.
