What is Domain Authority (DA)?
Domain Authority (DA) is a search engine ranking score developed originally by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). Domain Authority scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking well.
DA is calculated by evaluating multiple factors, including linking root domains and the total number of 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. DA is not exactly a metric used by Google in determining search rankings and has no effect on the specific SERPs; rather, it is an approximate metric modeled against the Google algorithm.
What is Page Authority (PA)?
While Domain Authority measures the predictive ranking strength of entire domains or subdomains, Page Authority measures the strength of individual pages. This makes PA a much more granular metric that SEOs can use to evaluate whether a specific blog post or product page has enough off-page credibility to outrank competing articles.
How to Improve Domain Authority
- Get High-Quality Links: Earning backlinks from high-DA sites acts as a "vote of confidence" for your domain.
- Reduce Spammy Links: Disavowing bulk automated links or private blog network (PBN) spam can lower your spam score.
- Enhance Internal Linking: A dense internal linking structure helps spread link equity from high PA pages to newer, lower PA pages effectively.
