Site DA is a score [developed by moz.com] that hints on the “strength” and relevance of a website for a specific subject area or industry. It’s a logarithmic scale of points, typically ranging from zero to 100, which predicts how well a website will rank on search engine result pages (SERPs). The higher the number of points, the higher is a website’s DA.
Now, don’t confuse the Website’s name authority(Domain Authority) with page authority. They are different.
While Website DA tells us about the overall ranking potential of the entire domain or website, whereas the page authority (PA) is the ranking potential of a single web page.
Both require tools to check. And that’s where we introduced to check domain authority tool for you.
