When configuring an engagement, we can specify user sample groups that should allow us to do A/B style testing. Unfortunately, that’s only half the puzzle, because we don’t have the ability to analyze the data filtered for those user groups. For example, we can tell an engagement to only show up to users in groups 1-50, but then we can’t filter for groups 1-50 when evaluating the results. Therefore, we can’t really do A/B testing or evaluate engagement effectiveness against control groups. Or at the very least, it is unnecessarily difficult.
This is CRUCIAL for evaluating engagement effectiveness, so please make the User Sample Groups available across PX for analysis and filtering .
P.S. Yes I have seen this post, but I don’t think the approach it advocates is effective. Growth over a time period is not a good compare, because it will be quite different when you first launch the engagement than it will be a few weeks later when there's a slower (but steadier) trickle of users seeing the engagement. You need to compare:
- How many users met the engagement's audience criteria but did not see the engagement? Of THOSE, how many users successfully scompleted the target action]? Or, what % ?completed the target action]?
- How many users met the engagement's audience criteria and DID see the engagement? Of THOSE, how many users successfully scompleted the target action]? Or, what % ?completed the target action]?
