What Are The Main Components of Domain Authority?

Domain Authority of a website depends on multiple factors such as:

Backlinks: You can raise the DA of your website by creating backlinks to your website from trusted web properties.” Some of the trusted web properties are Forbes, Wikipedia, Inc, Entrepreneur or any other authority site in your niche.

Earning high-authority backlinks can improve your Domain Authority score but, if you get backlinks from low-quality sites, such as spam sites, it can lower your Domain Authority score. Earning a few links from different websites will boost your score more than earning many links from the same website.

MozTrust: It measures how closely your site is related to trusted websites. Trusted sites include .edu and .gov sites. If a .edu site links to a site that then links to you is also considered a sign of trust. Similar to MozRank it also rates a site on a 0-10 scale (with 10 being the highest).

Technical SEO: It includes your site’s speed, quality content, page titles and descriptions, and internal linking. It is also based on User-friendliness of your website. Technical SEO is one of the few SEO strategies that you need to master in 2019.
