Missing sessions in Optimize
Hi, I created a "redirect" test in google optimize, running since 20 days approximately.
The general session count in analytics for this period is 447 sessions, in optimize it is only 300. (There are also important differences on the conversion count, but this is probably due to the same cause)
Do you have any idea how the difference may occur?
My setup: UA tag installed via GTM on the entire site. The experiment is limited to desktop and tablets (and so is the reference session count from analytics) looks as follows:
I am happy to provide additional information if required.
I first thought it was due to a possibility that experiment would only count new sessions, not of returning visitors. but as the conversions are also far lower in the experiment than in "reality" I believe there must be another issue.
Thank you for any advice.
