So I have been at this website for one year, it doesn't rank for many long tails so I don't get much traffic. It is one 3rd and second page for the keywords I want to rank for. I have tried adding relevant content trick, sent backlinks to them too. Added more content. Built more PBN links. The links are already diversified from the start they are web 2.0's, PBN's, profile, press release etc. Now I am thinking I will build 2-3 HQ web 2.0 and link to the homepage and innerpage from it and send sape links to it? Will it work? Are there any other solutions to it? Or send more PBN links to homepage?
