Chartboost has released their analytics as recorded over this last holiday season. No big shockers here, but still interesting to see trends.
Overall it look like advertisers were paying an average of 8% more to gain users during Halloween and Thanksgiving had 17% more games advertised than on Halloween. What's interesting to note is traffic seemed to increase quite a bit even outside the US though Thanksgiving isn't considered a holiday.
Christmas was huge this year! No surprise here but there were 4X the amount of downloads on Christmas day than any other day. And to wrap it all up, on New Years day the number of game sessions were doubled compared to that on Halloween.
So in summary:
Halloween 2012 was just a blip on the radar.
Thanksgiving was a good time for revenue but a bad time to get visibility because of the increased level of advertisers.
Christmas was good for almost everyone!
And on New Years there was alot of people playing games!
