Hi Target community,
I have a question around what duration should we set for profile lifetime.
Target's default setting is 2-week of inactivity.
What I realized from A/B tests that have been running 2 months or even longer is that conversion rates regressed
to mean regardless of how drastic the change is.
1. Does this mean the data has a certain level of cookie pollution from the sceanrio below?
Test launched on day 0. Visitor Tommy entered experience C on day 0.
Tommy hasn't visited the page where you're running your A/B test on in the next 14 days.
However, he visited it again on day 17th but placed in a difference experience, and eventually converted.
2. What's the profile lifetime setting you're using and why?
Again, much appreciated any inputs you have.
