In the SEO world, Authority refers to the “credibility” of a website in the eyes of search engines, and specifically to the level of trust and reputation a website has acquired over time. This authority or authority is determined by various factors, including the quality and relevance of the site’s content, the number and quality of inbound links, or the length of time the site has been online.

Purely theoretically, a site with high Authority is considered to be of high quality and trustworthy and therefore more likely to be ranked high in search results than sites with low Authority.

SEO theories distinguish two main types of authority: domain and page authority. Domain authority refers to the overall strength of the entire website domain, while page authority refers to the strength of a single web page within the site. In SEOZoom, Zoom Authority analyzes and measures domain authority, while Page Zoom Authority focuses on page-level authority.

Of course, there are many other proprietary metrics that assess this authority, such as the famous Domain Authority developed by Moz.
