AEP segments and Adobe Analytics filters

[TimBo4]

I am building batch audiences in AEP and the counts I am generating do not come close to the counts in Adobe Analytics that use the exact same evars/analytics. Why?

Hi Tim, 

your adobe analytics count may have multiple ECID, however in AEP you get the count of profiles which may be combination of ECID and multiple other factors hence you may not see the count is matching. Hope it helps.

That makes sense if the counts were reasonably close but in my case, there's a 180% difference between these two counts.

@TimBo4 Discrepancies between AEP batch audience counts and Adobe Analytics data can occur due to differences in data sources, audience evaluation logic, and identity resolution. AEP processes profile-level data with periodic updates, while Analytics operates at the hit/session level and offers near-real-time reporting.

My experience has been that at some point you need to sample.

Take any random ten profiles from the system where you see more than the other.

Then look to see what subset of the ten is in the other system, and for those that are not, investigate why they didn't make it into the same list. Usually once I under just two of those then I'm able to figure out what's going wrong.
