Adbrite.com offers a great ad service. It boils down to the following:
- Your site gets added to their database
- You put some ad-code on your site
- You choose how much money you want to charge every day/week/month/etc
- Advertisers can rent your ad space.
- Adbrite pays you on a NET-60 basis, letting you set the minimum check amount.
It works well. For a while, I was making $25/month off one of my websites. Unfortunately, the advertiser pulled the ad after a couple of months. Oh well.
Adbrite works great, just don’t expect to get advertisers too often…unless you get 200 unique visitors a day.
