We have just launched our first GPT website, we share our profits 50/50 with our members. We have offer walls, PTV PTC, PTSU, and premium ad slots. Come and have a look. We pay out in BTC but it must be requested via forums, or support request currently.
http://cpa-coin.comI think 50% share is very low if compare to other gpt site. Most of them share 70% up to 90% to attract user.
So you need unique features for user or they won't joint with you
