What Is Domain Authority?
Domain authority indicates the trust built on a particular domain based on its history, quality content, inbound links, traffic, safe browsing, uptime, and other factors. I use here the Domain and Page Authority scores developed by Moz, which allegedly is based upon the number and quality of links pointing to that site as well as a few other factors, which they have not made public.
So, a private company has made a proprietary metric to judge more than 1.5 billion websites without disclosing the factors the same way Google did with Pagerank and also says that its metric doesn’t affect the rankings. Hilarious, isn’t it?
Anyway, domain/page authority is scored on a 100-point logarithmic scale, so it’s easier to grow the score from 20 to 30 than it is to grow from 30 to 40. The metric updates one or two times a month, so the result you see reflects two or three weeks in domain history.
