I'm interested in the methodology they used for this study. It's been long-rumored that iOS users actually use their devices far more than Android but the difference is staggering. According to this study, iOS accounts for double the web traffic of Android.

The reason I find this particularly interesting is because it reflects my own websites, right down to the Android spike in June/July and the iOS resurgance in the fall. The thing is that my websites are dominated by North American traffic, though. It seems to me that iOS has always done disproportionately well in English-speaking countries (US, CAN, UK, AUS) while Android comes on strong in the non-English countries of Europe and Asia. I always figured that the ratio was skewed by my own web traffic being largely represented by middle-class people in North America who were early adopters of smartphones and iOS.

Either way, it's strange that iOS still has such a strong presence in my own web traffic while Android has teetered between 1/3rd and 1/2th the size of iOS traffic. Interesting stuff if you're a developer like I am.

uh yeah, but I-OS has also faced a lot of declines with its marketshare, and therefore the I-OS number for webtraffic has to be lower now.  Irregardless of I-OS vs Android, the trend is your friend and shows you the way.

That's the point. iOS web traffic is NOT trending lower. It's tracking at the same ratio to Android over the past six months.

This doesn't surprise me at all.

When people buy an iOS device, it's because they want to use it and plug in o the ecosystem. You don't spend 400+ dollars on a device you don't intend to use.

Chitika is a web advertising network, so they're basically just counting hits on their own network. So there's probably some amount of bias based on what kind of web sites and ads they serve. They seem to be US-based, but I don't see any text excluding web sites from around the world from using their services, so it's hard to guess what kind of regional bias they might have.

But their numbers are pretty consistent with NetMarketShare, which is global and works hard to try to eliminate bias from their metrics.

They're also consistent with Google's own numbers for 2011 mobile search ad revenue.
