I just set up a new Paypal account, and I'm currently selling Ads in my site. http://www.thegermz.com/advertise Since I just started I'm selling them at a very low price. What I'm not sure Is how I'll be able to know who bought my ads... like if someone were to buy one right now I'd just mail them using the paypal email they used, and see their specifications. But right now I have no idea on how to like contact the person or something that will tell them to input the certain ad that they want.
Wait I'm not understanding you. You mean I should get an account in a place that sells ads? what do search engines have to do with contacting my costumers? Thanks
