Hello it starts when 1-2 months ago i find few backlinks to one of my sites in japanese boards, which i don't did myself. after this i did a small marketing and find (first time for me) that a lot of people are in this business. just name this group -"doorway-spam-webmasters" i don't going to tell, how they are doing their business (as i don't know enough), but i understand few stages of this business 1. generate 1K-1MLN doorways (with redirect or without) 2. spam this doorway pages on different boars and forums. 3. open account on ppc (like umax, 7search, etc) and make money, until google don't BAN their sites as they told, this time period can be different (1 week -2-3 months) now the question , for what i open this ticket why google ban this sites? 1. for doorways () 2. for redirect doorways 3. for spam 4. for all of this? why i ask this question? because, if only for spam on different boards, sites can be baned, every1 can find such a smap-webmaster, and ask to make such "spam" site of this competitor any opinion?
They do it because of the doorways and because of the redirect. Doorways from what I know means keyword stuffing ... Google is against. You will also find it in their Adsense TOS I think that they don't encourage the creation of doorways and that your site might get banned from the results. Anyone from the forum with doorways/cloaking ? I might have a very good solution to monetize that traffic. Contact me for more info.
