Hello BHT, All of my sites backilns have about 10% exact keyword, and all of them dropped to page 2 for the targeted keyword. After looking at google serp, I notice that all top 10 do not have and exact anchor text pointing to their site. ex, If exact anchor is "red cars reviews" The top 10 will usually use : - red cars - the best and worst of red cars - Car types explained : blue, red, black -... etc None of them use the exact keyword as an anchor backlink but they still rank for top 10. I read a lot about hummingbird and how it works, tried to add many LSI, change the title and separate keyword, just like the top 10 ranked in google. Now, My question : If I build a new site. Should I use 10% exact anchor text backlinks, Or LSI as top 10 in google serp usually have? Hope I can find an answer here note: all my sites have high DA and DT.
