For one of the sites I am working with I keep an eye on the traffic coming to it from mobile devices. Every week I put in the numbers for total number of mobile visits and also per mobile OS for each day, and today when I did the numbers for last week it did look a bit strange. So here’s what I found.
To begin, let me tell you how I do this.
I get the total mobile visits numbers by going to Visitors > Mobile > Overview
I get the iOS numbers from Visitors > Mobile > Devices > Mobile Device Branding looking at the Apple row
I get the Android numbers from Visitors > Mobile > Devices > Operating system
I get the “Other” numbers as total – iOS – Android
So what did I find in this week’s report?
I found that, starting wednesday October 12, the iOS numbers started to go down. I immediately connected this to the iOS 5 release which was on that day, and when I saw that the “other” column was going up a lot I started to suspect that Google Analytics didn’t recognize iOS 5 devices as Apple devices.
And when I looked in the Operating Systems report, and added the iPhone, iPad and iPod numbers together I found that those before the 12th were almost the same as the Apple numbers in the Device Branding report (98-99% correlating), but starting on the 12th that correlation decreased for every day, from 96% on the 12th down to 69% on the 16th.
The problem here seems to be that from the 12th of October some iOS devices are not recognized as Apple products, and I can’t see any other explanation to this than that it is because of iOS 5.
