The problem is that search engines are not public about how they calculate authority, so several tools have developed their metrics for these. In SEO, this authority is determined by links-more specifically, quality links from other sites to yours. Search engines predominantly rely on the authority of pages and websites along with domain age to identify which pages to rank above the others.Īccording to search engines, the more authoritative a web page (and the website to which it belongs) is, the more likely it is to offer reliable answers to its visitors. There are bound to be more than ten (the number of pages included in the first page of the search results) good answers for each search query. There are above one hundred trillion (that’s one followed by 14 zeros) web pages indexed on Google alone. Why Are Authority Metrics Important for SEO? Website authority checkers and page authority checkers follow the same approach to evaluate Page authority and domain authority. Page authority is concerned with a particular web page ranking, while domain authority is concerned with the overall domain authority of a website, which encompasses all of the web pages on the site. The Difference Between Domain Authority & Page Authorityīoth terms may sound similar, but there's a difference between them. Many domain authority checkers will also evaluate page authority. Page Authority is a metric similar to domain authority used to estimate how a page or a specific URL from the site will rank in search engine results. When you use a DA checker tool like this, it’s always from a third party. It’s important to remember that the DA score is an estimate made by a third-party company and NOT Google. The score is solely based on the quality of links going to a website. You can calculate domain authority scores with the help of free tools available online.

Third-party SEO tools like Moz, SEMRush, Ahrefs, and Majestic calculate DA. Having a High Domain Authority Score is important because it directly impacts the ranking potential of the website on SERPs. It describes the relevance and credibility of the website in a related niche. Domain authority (DA) represents how authoritative a website is on a scale of 0-100.
