IE & Edge issues with site relaunch - advice appreciated

[AndyMacLean]

Hi,

I've been involved in a major ecommerce site relaunch, redesign and backend and have been involved in several successful ones before. On the whole things have gone great. Of course there are some minor bugs to fix, rendering issues etc but my real concern is a significant decline in conversion rate BUT only for IE and Edge users. All other major browsers conv rate has increased.

Trawling through analytics and the site itself in those browsers there is no obvious sticking points e.g bounce rate has improved on all browser inc IE & Edge, no particular point in the funnel is suffering more than others, no particular page or landing page is doing much worse than others etc. it just seems like all the kpi's (except bounce) are down a little on the 2 microsoft browsers, which has a significant impact.

One of the things that changed on relaunch is that we moved to https and im wondering if that might be causing an issue with IE / Edge security or privacy settings or that functionality on the site that relies on cookies is being affected, though in testing we haven't come across anything.

I'd appreciate any advice or insight.

Thanks,

Andy
