Here is the data.
I took 2 time slices - Aug 11 to 29 and Sept 8 to Sept 26. These roughly represent Chrome 36 and Chrome 37 (with some overlap). Leaving out Sept 1st week to reduce impact of Labor day weekend related traffic.
Over these 2 time periods, I checked the change in metrics for desktop google browsers (Chrome all versions - mostly 36 and 37) and desktop microsoft browsers (IE all versions - mostly 11, 10, 9, 8).
Page views (mean)
- Increase of 38.71 % for Chrome
- Increase of 16.19% for IE
- Increase of 65.93% % for Chrome
- Increase of 14.44% for IE
- Increase of 353.88% for Chrome
- Increase of 16.67% for IE
Bounce rate (mean)
- Increase of 174.15 % for Chrome (from 10.56 to 28.95)
- Increase of 11.02% for IE (from 7.71 to 7.96)
- Increase of 34.36% for Chrome
- Increase of 14.52% for IE
I can send the actual numbers if that helps.
In general there is a bigger increase for all stats in Chrome, but the visits, bounces and bounce rate seem to have increased far more than the page views and orders.
I am not sure what this means and if it helps form any hypothesis related to Chrome 37 and/or Tealium js.
Any help is appreciated. Let me know if I should mail the actual numbers.
