The more traffic a website gets, the higher the chance that people will click on a backlink and visit your site. Google recognizes this, and that’s why a backlink from a website with a lot of traffic will typically benefit your site.
In theory, a site with a high DA or DR gets a lot of traffic. However, this isn’t always the case. Some websites have a high DA but have very little traffic. For this reason, it’s worth checking the number of visitors a website gets before you try to get a backlink from them.
