Seriously, why bother answering, if you are just going to spout super high level points which have nothing to do with the question
@VSYNC - You need links from other high DR/UR sites. Plain and simple. Your DR will not increase proportionately to your UR if you are sending links to your inner pages, if you want to increase your DR, you need to link to your domain root.
There are methods to increase your Ahrefs DR and UR, you just need to think outside of the box. And before anyone asks why you would want to do this as it has no direct effect on your rankings, perhaps you want to sell guest posts on fiverr...
