So lets say that I am targeting very low competition, long tail keywords. I want to make 20 web 2.0 links and point them at my money site articles. Is it okay to only use 10 web 2.0 Platforms? Say 80% do follow and 20% no follow? Would google be suspicious If I only had links coming from ten different sites? I am currently using 10 different web 2.0 platforms for all of my articles links. Usually around 20-25 per article. In the future I want to find some expired domains and point make a PBN but that is later down the line.
