Domain Authority (DA) is a score developed by Moz, a leader in SEO software, that predicts how well a website will rank on search engine result pages (SERPs). The score ranges from one to 100, with higher scores corresponding to a greater ability to rank.
Domain Authority is calculated by evaluating multiple factors, including linking root domains and the number of total links, into a single DA score. This score can then be used when comparing websites or tracking the 'ranking strength' of a website over time. It's important to note that Domain Authority is not a metric used by Google in determining search rankings and has no effect on the SERPs.
There isn't a specific number that denotes a good Domain Authority score because it's a comparative tool, not an absolute metric. A good DA score for your website should be higher than your competitors'.
Improving your Domain Authority is not a one-time task but a continuous process. It involves improving your overall SEO, creating compelling content, and earning high-quality backlinks.
Moz, the creator of Domain Authority, offers a suite of SEO tools including a Domain Authority checker. Other SEO tools like SEMRush and Ahrefs offer similar metrics with slightly different calculations.
Domain Authority is a useful metric for comparing your site's ability to rank in search engines against other sites. It can also help you understand the effectiveness of your SEO efforts and identify areas for improvement.
While Domain Authority is not a Google ranking factor, it's a helpful SEO tool for digital marketers and website owners to gauge the ranking potential of their websites and track improvements over time.
