Lookback windows
The 30-day default in v1, why it's fixed, and what happens to sessions outside the window.
Coming soon. This article will document the 30-day lookback in detail, the reasoning, what happens to older sessions, and the post-v1 plan for configurable windows.
Topics this article will cover
- The 30-day default and why we picked it
- Per-conversion (not per-visitor) lookback
- What happens to sessions outside the window in the Visitor Journey UI
- Comparison to Meta / Google default lookbacks
- Configurable lookback (post-v1)
For now, the lookback rule is documented in How attribution is computed.
