Domain authority is the evaluation of the influence or strength of a website and is measured on a scale of 0-100. It’s a key criterion that search engines use to find out whether your website is really trustworthy and credible.
Websites that have high domain authority enjoy the benefit of being ranked at the top of search results. There are three factors that decide the domain authority –
· Age of the website
· Popularity of the website
· Size of the website
The time period for which a particular website has been in existence matters a lot when it comes to calculating the domain authority. The overall popularity of a website is also one of the key factors for determining domain authority. Size is important because it tells search engines the extent of information that a particular website features or contains. Based on all these three factors, search engines calculate the domain authority of a website and then use it as one of the most important criteria for ranking in search results.
Page Authority measures the strength of individual pages.
