We have launched a new ad network that we thought is pretty different and innovative compared to the rest of the ad networks in the market today. Seeing this, we thought finding publishers to give it a try may not be a very difficult move. But that doesn't seem to be the case. Unlike product promotion where you need to get people to spend money, I thought ad networks were easier to sell considering it is free to sign up and also helps you make money. So what could be the issue here? People who have marketed similar products; could you share your experience?
