Hi, first post! I started with email marketing about a year and hal;f ago, in the last 6 months with mobile display, mostly CPA/CPL/CPC. I'm currently looking to expand a bit more into CPI with a few questions in mind: - Is there a site today that shows app quality, and I mean real unbiased reviews, if there is such a place still.. - What are the key differences between CPA and CPI, in terms of planning your campaign strat.? - I heard there a few issues today in this industry, one of them is very low margins for the game dev's.. how true do you think that is? Thanks!
