I made a mistake when I started my site, and I bought “high quality” backlinks from fiver. Forgot about it and didn’t really built any backlinks since my site got some traffic but lately it’s getting barely any organic traffic. How much backlinks do I need to get to about 20 DR? And from what DR can I see a jump in search engine rankings? And also are there sites where I can post my backlinks for free and they are do follow? I have an adult site, ahrefs says 1800 backlinks, google search console says 46.
