Wondered if anyone has had any success with Skimlinks? It basically takes any outbound links you have and converts them to an affiliate code. They have around 14,000 vendors in their affiliate database, so people with forums etc that are like 2-3 years old would certainly benefit if people are still reading their old posts. On top of Adsense, it has increased my earnings by around 25% at the moment, not sure if it has just been luck of the draw though, so i'll keep you all informed.
I tried. It's good. Also Joined VigLink too. I have site and placed both. It gives not too much like AdSense but it's good than nothing. If you thinking to join such a services, please look this page.I compared both services http:// erdem_ua.users.sourceforge.net/viglink_vs_skimlinks.html Also became member from links at my page than I can receive referral money from the companies
