Hi,guys I am a software developer. I plan to embed ad into my software to make it free. For the ad displays in software but not in browser, I guess the static link (website.com/?aff=user) is the only way. Do you have better ideas? PPC is better? Besides, Which type of ad should I choose? I'll appreciate your help. BTW, I am looking for a business partner. If you have interest, plz drop me a line (kit@kit3d.com)
