Some one reedit in better english than mine. Very big thanks to #http://www.blackhatworld.com/members/azurous.842407/ Read bellow. Thanks a lot because I'm not so good in English. Part one missing. Some unofficial info from my network tell me that in last update of Google were "penalized" over 1.000.000 Landing pages and over 300.000 PBNs just in 1 hour and numbers is increasing. Part 2 missing Source from http://www.blackhatworld.com/seo/the-final-blow-to-negative-seo.881575/ Member #http://www.blackhatworld.com/members/soa0611.865958/ http://www.blackhatworld.com/goto/post?id=9316523#post-9316523 From what i've seen over the last few weeks negative seo still works. However would like to keep checking over the next few months and see what impacts it has. hey man, hows your site after penguin? so you added naked url instead of exact matches and your site is back to previous positions till now? for mine - i had mad fluctuations all Sept and for the last 2 days all my KWs totally disappeared from serps. what would u advice - abandon the site or try to fix the anchor ratio or smth else? ,instead of that opposite you will be entitled to beg your blog posts to be erased. This is the way how the PBN owners will make money. Pay to erase the blog post to return ranking. Part 3 missing Note:In note Must be Google Page Rank.
