Each site has different features that may make it easier for you to make money than it is for another person based on how you use the site. For example, one site may have higher payouts, but take over a month to send you money. I don't mean to blindly promote my site but from what I see in our competition, Dollar Hauler payouts are relatively high. They may not be the highest but you will end up getting your money faster and its pretty reliable. Otherwise try searching for different GPT sites and create an account to see what kind of offers they provide you with and how much they pay. Good luck!
