I am just writing with a call for help and advice. On one of our web sites we have noticed a recent drop in sales in one specific visitor segment (two, actually -- more on that after.)
We have been comparing the first 15 days of June to the first 15 days of May.
The issue that has been observed is with visitors on Windows 7, and reaches across IE, Chrome and Firefox. Overall there has been a 55% drop in conversions here. On the other side, Windows XP and Vista have an increase in conversions of 40% or more (although the sample is considerably smaller.) Windows 8 shows a small drop, but has a miniscule sample size.
Macintosh-based sales are up 8%.
In addition to the Windows 7 problem we've seen a drop in iOS conversions too. While its a much smaller sample size the drop is about 37%.
Thanks to the all analytics data we have access to I have been able to rule out any screen color/resolution issue (as the drop seems to span across these proportionally.) It also does not appear to be a regional/geographic issue either.
What I'm hoping is that some of you may have access to a Windows 7 system and that you could visit our site (I'll post it if someone can confirm that's OK to do here.) I'd love to find out from as many people as possible if there are any drawing/button/speed issues.
