I'm planing to get some Wikipedia links for my authority blogs. Tho, i see many people talk about the "no-follow" scenario of Wikipedia links, i'm just curious to know if "No-follow" from Wikipedia do have some SEO value? i'm again curious to know if i start some PBN, is it a good idea to get PBN sites which has wiki backlinks, good link profile and matrices? What exactly these days working for "competitive keywords" other than PBN and web 2.0's ? i'm really worried as all my keywords struck between 8-20, no matter what niche it is. Answers are appreciated, If you don't feel like sharing info public i'd love the PM.
