I'm currently in the process of trying to dedupe the Activity Conversions metric that appears when A4T is selected as the reporting source in Target. The primary reason I'm doing is because I want to capture the 'percentage of visitors in my activity that have clicked or engaged with an element being clicktracked on the page'.
Referring back to this documentation: How Do I View the Conversion Rate, Lift, and Confidence Level? | Adobe Target "For A4T, we use a Student’s t-test calculation for continuous variables (rather than binary metrics). In Analytics, a visitor is always tracked, and every action taken is counted. Therefore, if the visitor purchases multiple times or visit a success metric multiple times, those additional hits are counted. This makes the metric a continuous variable."
Because A4T captures every action that was taken, I am unable to use this metric to capture visitor level interactions. If I used Adobe Target as the default reporting source, then I would have been able to use metric as the number of conversions is contingent on the normalizing metric being selected.
That brings me to this question: If I wanted to extract the deduped visitors, is there a way that I can create a segment to place on-top of the UV metric which captures the number of unique visitors that engaged with the element that I was click-tracking using A4T? I've attempted to build this segment myself, however the segment always returns 0 conversions/unique visitors.
I was going to suggest you could create a segment where "activity conversions" exists and then put it on top of a unique visitor metric. However, it doesn't look like "activity conversions" is able to be used in a segment only native AA metrics are I guess. Are you suspicious that some visitors repeat the conversion step a lot? You could try using different baselines to determine this. Like activity conversion per visit. Or per page view.
