So, will try to do this the shortest possible. I had some page ranking ~60's for med comp kw. Sent it some foundation links like PR's, profile links, some web 2.0's and some Public blog network links - all were brand/generic/naked/longtails anchors. This got me to the 30's, again - I haven't sent any exact match anchors yet. Then I sent 3 exact match PBN links from my Private blog network and the site jumped to 50's for some reason, I thought it will comeback but nada. Note: At the meantime, more and more profile links are getting indexed from the package I ordered when starting SEOing this page. So I just let it dance for like a month and BAM, site jumped to 150's. It's more than a month now that it's there. I never ever saw something like that (And I'm tracking every KW's I'm targeting). I checked anchors and indexation of my links just to make sure everythign is right. Have around 100 links indexed, balanced generic/longtails/naked/brand and only 3 Exact Match PBN links. I'm seriously have no clue what is happening here, the only option I can think of is that about 50% of my links are profile links with diversified anchors and maybe Google see this as spam. Not sure whether I should start building Exact match keywords again or what?
