By using several indicators, it can predict how well a site will rank on SERPs. Indicators include the number and quality of backlinks to your site, social media presence (including engagement), and how optimized your site is from a technical standpoint.
Scores range from 1 to 100, with sites like Google, Facebook, and Wikipedia scoring in the high 90s. However, DA scores are meant to be used as a comparative tool, and the goal is to score better than your competitors, rather than chasing a high score.
For example, if you owned an eCommerce store that sells gloves, comparing your DA score against Wikipedia’s DA score would be an ineffective way to measure how well your site is ranking. Instead, you would need to research the DA scores of your competitors and other online stores selling gloves, and see how you score against them.
