In the new blog post titled “Understanding Browser Usage Share Data”, Microsoft’s Roger Capriotti has revealed why Net Applications and StatCounter stats seem to differ.
While you might think that the only difference is sampling size, there is actually more to it. As it turns out, thanks to pre-rendering, StatCounter gathered data from the Google Chrome web browser even if users did not visit the mentioned web sites, which as a result, influenced the numbers. Although traffic statistics has been since tweaked to address the issue, Microsoft reports that a total of 4.3% Chrome’s daily visits were caused by pre-rendering.
In addition to that, StatCounter just calculates the absolute page views for its information and does not consider geoweighting, which Net Application does. How exactly does it impact the situation? Well, StatCounter ranks China as the 22nd country when it comes to the number of Internet users when in reality it’s number 1.
Here is what Net Applications had to say
If our global data shows that Brazil represents 2 (percent) of our traffic, and the CIA table shows Brazil to represent 4 (percent) of global Internet traffic, we will count each unique visitor from Brazil twice. This is done to balance out our global data.
So what can you take from the study? Well, as seen in the picture above, Microsoft went ahead and compared reported vs. adjusted browser market share and results speak for themselves, at least when it comes to the IE market share.
