HI -
Adobe can explain it better than I can!
The Target variable sent to Analytics has a default 90-day expiration period. This expiration period can be adjusted by Customer Care if needed. This setting is global for all activities; however, so it should not be adjusted for one case.
You might see Target variables sent to Analytics after the expiration period because the expiration is 90 days, but only if that user never sees another A4T-enabled Target activity. If a user comes back to the site on day 45 and sees another activity, the entire A4T eVar value has its counter reset to 90 days. That means the first campaign from day 1 now could be persisting for up to 45 + 90 = 135 days. If the user keeps coming back, you might get to the point where you see metrics sent to Analytics in your reporting from much older activities. As users delete cookies and don’t return to the site, the numbers in that activity drop, but you can still see them.
Why are Target metrics sent to Analytics even after the activity has been deactivated?
Thanks,
Shari
