Domain Authority

Domain Authority predicts a website's ability to rank in search engines.


Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine results pages (SERPs). DA scores range 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 does not affect SERPs directly. Instead, it is a tool used by marketers to estimate the potential of a site to rank based on its backlink profile and other SEO factors. Since DA is relative, it's best used as a comparative metric rather than an absolute score of your SEO performance.

    Is it possible for Domain Authority to decrease?

    Yes, Domain Authority can decrease if a website loses backlinks from high-quality sources, or if higher-authority sites receive significant link growth, changing the scoring baseline. It's important to continuously work on SEO and link-building strategies.
