I have an A/B test where there is a 90%/10% split in traffic (unique visitors are respecting this split), but visits for the groups are coming out as 85%/15%. Is there a reason why we're seeing this higher concentration of visits in one group?
Also, is there any chance that Unique visitors could be reporting low in either group?
Thanks for the response. I realize it's return visits, but there isn't a reason for one group to have more return visits than another. There are millions of visitors in the test. It seems like an anomaly for there to be a larger amount of visits per unique in one group over the other.
Since we are both on the same page about return visitors. Help me understand what numbers you would expect to see for visits percentage when looking at ExpA vs ExpB curently while you have 1:9 visitor ratio between the experiences the visit ratio is a bit lower 1:5.6
ExpA: 90% Visitors
ExpB: 10% Visitors
The ratio is 1:9 (So for every one visitor in ExpB we have 9 visitors in ExpA)
ExpA: 85 Visits
ExpB: 15 Visits
The ratio is 1:5.6 (So for ever one visit in ExpB we have 5.6 visits in ExpA)
