### Targeting based on First Seen Timestamp

Thomas Kainrad

**What it is:** A built-in "First Seen" user property is now available in Guides and Surveys' remote evaluation. Cohort-based new user targeting has a reliability problem: membership updates run with a delay, so a brand-new user won't be included until after their first session has already passed. "First Seen" sidesteps this by pulling the timestamp directly from the amp ID table at evaluation time, so targeting works on the very first visit.

**Where:** Guides and Surveys Builder

**Who:** All Guides and Surveys users. EUDC: Yes.

**When:** GA. Available now.
