Ahrefs Domain Rating (DR)

- Best for evaluating link building opportunities
Which one is better?
The truth is: **You need both.** Moz is excellent for predicting how a site might rank in search, while Ahrefs provides the most up-to-date and granular backlink data. Most professional SEOs use DA as a benchmark and DR to qualify individual link prospects.
