Hi, I was wondering what's your defination of a bad neighbour? Does it only apply to Google only? Does a outgoing link to a site banned by google hurt my ranking with other search engine? Apart from warez, hacks and other illegal stuff related sites, what other site category would you consider a bad neighbour?
No one knows for sure how G thinks. Its only when someone gets kicked by them that they start thinking what all they did since last update. Bad neighbourhood can be link farm, but then some link farms are more than PR5 and rank very high on search results.
sites who applies black seo to their sites. if you link to a bad site, your rank for all of the search engine will be effected
