Hello,
My team recently enabled eVars that track cookie opt-in/out information for three cookie categories. For each of these, if a visitor opts out of a category and then opts in, we'd like to be able to segment visitors by their most recent selection. Do you know how to build a segment based off visitors' most recently defined eVar value?
Thank you,
Ben
So this solution might seem a bit crazy.. but you have 2 values "opt-in" and "opt-out", and the user can change their value at any time.. so if you want to pull back UVs where the last value collected was "opt-in", you can do so with a calculated metric:
Using the IF function, you can use custom attribution on the "eVarX Instance" for "Last Touch | 30 Days" (or whatever period you need)
and a segment looking at eVarX equals "opt-in", if true, then return UVs metric, otherwise, return a static value of 0:
You can change the attribution of the metric here by clicking on the gear:
This way you can get the last touch for a specific value (i.e. opt-in)
If you just use the attribution model directly in the freeform, depending on your breakdown dimension, you could still be getting previous values as they were the "last value set on that dimension"... so you need to be careful that you aren't getting inflated values...
Those last touch attributions are great when you are looking at things like purchase conversions... but you are trying to get a sense of the current opt-in rate, and that complicates matters.

Try a sequential "visitor" segment using non-repeating instances your dimension (with "Only after sequence" applied to the segment). Most* of the data in the dimension report should be the "last one in" in the date range you have selected.
*It's "most" but not "all" because any additional opt-in/out selections made after the first opt-out>opt-in pair will all be returned for that visitor in this segment, but I can't imagine that very many people would do that.
Yep, I agree my original segment is imperfect. As I mentioned, additional opt-in/out selections made after the first opt-out>opt-in pair will all be returned for that visitor in my original segment. @bhutton here's an updated segment that I think will give you what you're looking for:
Change the segment to a "hit" segment and add two "visitor" containers (with an "AND" between the two containers).
The combination of these two containers in a "hit" segment should return the last "Onetrust Function Cookies" value within visitors that selected opt-out then opt-in at any time within your selected date range.
For me, the key to understanding how each of these sequential segment containers work is the fact that the "only after sequence" and "only before sequence" settings names are a bit misleading (at best) because they also return one of the hits within the matching sequence.
