Does Real Time Segment Population take Media Pixel Fires into account?
Say I have an 1st party onboarded segment of current customers.
Total Segment Population: 10,000
Real Time Segment Population: 0
I run a media campaign against those users and have a pixel placed in DCM to capture impressions. Let's say 5,000 of those users received an ad. None of them show up on site or in-app. Just receive a media impression.
Is my Real Time Segment Population 0 or 5,000 now? I just want to understand what it means by "reaching your properties". Is that wherever your demdex pixel/DIL Code (or SSF) recognizes the same ECID? Or is it only when they show up on site?
Thank you.
