I purchased a income generating domain that makes about 120/month is the seller supposed to give me other besides the name because I'm not quite sure how to get the revenue to me. Do I need to set up certain things in order for the earnings to go to me or is it automatic once you have the domain?
All revenue generated from the previous owner is theirs. Unless you bought the entire site you will have to generate incom in your own way with a new site.
