First, the worst: Project Wonderful
Not wonderful for advertising a mobile game. I should have known this wouldn't be a good platform since the ads are not primarily on mobile devices. Don't be lured in by their cheap rates. Most of the websites with ads on this network kinda suck. I had a really poor click-through rate and it probably wasn't giving me high-quality users. Not even worth posting the stats... (not gonna bother looking it up).
Facebook Vs. Chartboost
Facebook uses the "install this app" in your facebook feed and chartboost uses interstitial ads in game.
I did facebook second upon a recommendation I read online. First off, I should have installed the SDK so that I could have tracked my install rate. Since I didn't, I'll be fair and try to only compare facebook to chartboost in the comparable metrics for which I have both sets of data. The other thing to note is that I paid facebook per click and I paid chartboost per install (which I chose the minimum at .50 cents.) .
Also, I spent a lot more money on chartboost than facebook. (thankfully)
Facebook: $26.64 (split over about 5 days)
Chartboost: $172 (split over 3 days)
Most shocking comparison:
Cost per click
facebook: .24 cents USD
chartboost: .005 cents USD
cost per Impression
facebook: 5.92 USD
chartboost: .39 cents (yeah, this cost 6% of what facebook cost)
Based on this I can tell that chartboost is giving me the higher quality users, and A LOT more value for my money. If you're not convinced yet, heres the last nail in facebooks coffin: I paid chartboost per install, so I know exactly what I'm getting from them. There isn't any gambling involved. Facebook ads are like throwing money out the window and hoping some lands in your yard. Chartboost delivered 344 installs for me. I wish I knew how many facebook actually delivered, but who cares. Based on my google stats it wasn't performing anywhere near chartboost.
