Hello, i must admit that i'm extremly confused about the paid links and new PR algorithm. Let's say i have a site and some people want to advertise on my site. I sell them some advertising space for banners and links. Can i get penalized for this ? If all the links that i sold are with "nofollow", which means are there only for traffic purpose, than i'm in the clear and no PR penalty for my site ? I'm pretty confused , can somebody please explain this to me ? Thanks.
You will safe. Don't let google know you sell link is "text link" and only sell link hasn't nofollow tag others has.
