What is domain authority?
Domain authority is a search engine ranking grade or score that is between 0-100. This grade gives Moz which is a popular company offering many SEO tools in USA.
From the domain score, it shows how likely you are to rank your domain in the search engine. The higher the score of the blog, the more I will show in that ranking.
That is, one website has a score of 30 and the other has a 40 to 40 rank website that will be in the top in search engine results pages (SERPs).
For example, you can see Wikipedia, whose DA score is 100 and its pages are always at the top in the search engine.
Domain authority depends on many factors. If you are thinking that you have started a blog today and the domain authority of your blog will be 40 to 50, then it is not possible at all.
To increase the domain authority of the website, you will have to work on SEO. It is very easy to increase the domain authority from 15 to 30 but if you talk 65 to 75 or 75 to 85 then it is very difficult.
