I use a number of pop up networks around 8-10 on my websites. I have toyed with the idea of running my own pop up network. I have found a script used by a few ad networks already. Pretty expensive but I am willing to invest. I also have a lot of free time to invest and always have internet access which I will know I will need. The trouble is I am still trying to decide what business model to take. Attracting publishers would be easy for me i believe as I control a few youtube channels and websites aimed at website owners with a medium sized following. However I wanted some advice on how I would gain advertisers through other networks. I would ideally like to partner with popads and popcash as I have used them both since they opened and chatted with both owners briefly. I have added a few other big advertisers on skype and will be contacting them shortly for their direct link to serve their ads and revenue share. I am hoping to do either a 90/10 and maybe a 95/5 split with publishers. I am aiming for daily payments... probably $5 minimum payout and $10 for advertisers. any advice given or other ad networks wish to partner or create legal relations please get in contact. I have a company registered in the UK which the website will go into as well.
There's a lot of pop up / popunder networks, but I suggest you to focus on niche popunders. Contact me via private message, I can help you with this - it's great idea and should work (for advertisers and for publishers very well).
