Hi!
To calculate A/B test sample size I need to know
a) the number of unique visitors to the page where we will conduct a test and
b) the number of conversions (for unique users who first see the variation or original and then convert in that order)
We have just implemented a cookie solution. We assign visitors into a test under visit 1 but not straight away if they accept the cookies on the page where the test is being conducted (since they would then see how the page behind the cookie banner suddenly changed). However, if they accept the cookies and then return to the page under visit 1, they are assigned to a test.
This means that a visitor who lands on a page where we are running a test and then straight away convert from that page never get assigned to a test.
Hence, our Adobe Analytics data might be off for sample size calculations since we start sending data straight away once the cookie banner is accepted.
What I need is a segment that takes this into account. If I could get some help I would be very grateful!
Thanks
