What is Domain Authority (DA)?

High Authority Domains or Domain Authority (DA) is an SEO measurement developed by MOZ an SEO software developer. Domain Authority is a made up SEO concept, DA isn’t actually used by Google or any other search engines algorithm, but it can be a useful very rough guide to the SEO value of a domain.

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank.

In brief DA is a little like PageRank which Google does use in it’s organic ranking algorithm, Google used to publish a webpages PageRank (a crude measure of the value of backlinks to a webpage), but 5+ years ago they stop publishing a webpages public PageRank score and Google didn’t supply an alternative.

SEO’s liked having access to PageRank, so when MOZ developed DA as a replacement, many SEOs and webmasters used DA values like they are an accurate measure of a websites SEO value. High DA domains tend to have a lot of backlinks (what DA measures).

Domain Authority and Page Authority (PA) are useful SEO tools, but always remember they aren’t real Google ranking values. Google doesn’t use DA or PA in their search algorithm, so use the values as a very rough guide to the value of backlinks to website/webpage and how likely a webpage would rank for a SERP.
