I'm trying to build a segment, that includes visitors that has had an instance of an event 1 month prior to the present. I want to use the segment in target for re-targeting among other things. I other words, I want to build a rolling segment.
The best way I've been able to come up with, is setting events for this particular purpose, that have an expiration of 1 month (in this case), but this wouldn't give us the flexibility we require and it would also require re-tagging. Can anyone tell me how to do this?
That exact segment was also what clientcare recomended. I expected the segment to return a lot of visits etc in the last 1 month, and then very few in the months before. That seems logical, when looking at visitors, who had an instance on the evar in the last month. What it does, is more like the opposite - it returns proportionally fewer visitors in the last 30 days compared to the months before. Something must be wrong somewhere.
I've attached an image, that shows the key metrics report for the segment. I've also attached what the same report looks like with no segment.
