Recently I bought package of 10 2.0 webs that linked to my money site . The content pretty quality but there a problem that lead me into some questions. If on the blogger account for instance theres more 5 other blogs (dont related to my niche and linked to other website) this case can penalized my website ?(that like I said - linked to 1 of the blogs), google can see that as Blog Network or something ? Plus, In which case my 2.0 webs can penalized my moneysite ? (without blast crappy backlinks on the 2.0's) Last thing: I read that blog networks (except the one that you own it) are dangerous backlink source. Im really confused because I think that I didnt relized what blog network is, can you give me an example ? If it really risk your moneysite why people here buying "Blog Posts" in XXXX$ from a Networks (They reporting on improvemnt in SERPS and the service get 5 stars and alot of positive reviews.) Hope Ill find answers to those Have good day !
