Mobile app marketing costs spiked over the holidays

Dive Summary:

The Boston-based app marketing company Fiksu reported that mobile app marketing costs rose 30% in November from October.
Despite that rise, the company reported that the average number of downloads for the top 200 free iPhone apps in the U.S. dropped to 4.57 million per day in November, a significant drop compared with 5.4 million in October.
Download numbers for December, meanwhile, will be interesting to watch at the end of the month, as the mobile analytics startup Flurry reported that app downloads spiked on Chistmas Day, hitting the 328 million mark.

From the article:

"... Fiksu said the average number of downloads for the top 200 free iPhone apps in the U.S. declined to 4.57 million per day in November, down from 5.4 million in October. This is a temporary decline following the annual bump that comes with the launch of a new Iphone. When consumers get new phones around the annual iPhone launch or Christmas, downloads spike temporarily as people try out new apps or download old favorites. ..."
