I always see high PR domains which obviously sell blogroll links and I was wondering where does the owner find these buyers? I have a few domains (with PR of 3 and 4) that could be used to sell backlinks to interested buyers. Another question is my domains are PR 3 and 4... how much should I charge for blogroll links? And is this per month or what? I have zero experience doing this kind of stuff and I'd appreciate any input. EDIT: These domains have very low outbound links, btw (only two per site total).
