I have done some reading but I cant get to the bottom of the difference between PPI vs PPD. (this is all new territory to me) So I have been reading that PPI involves being able to drive downloads to free apps and getting paid 2-3$ per free app that was downloaded. If this is true, can social media be used for this? All I have been reading is methods regarding youtube and installing apps to their computers for payouts around $.30 Can somebody clear this up for me?? Also if these networks are paying 2-3$ per install of their free app directly to an ios smartphone and accept social traffic let me know, and I am open for a JV to make some serious money with somebody with PPI knowledge/experience. Thanks!
