Choosing an evaluation method
| Method | Speed | Typical use |
|---|---|---|
| Batch | Scheduled | Complex rules, large lookbacks, daily campaigns |
| Streaming | Near real time | Event-triggered journeys and fast suppression |
| Edge | Instant | Same-page or next-page personalisation |
Each method supports different rule types; check the current Adobe eligibility rules before relying on streaming or edge evaluation.
Examples
- High-value customers: lifetime spend above a threshold and purchase in the last 90 days.
- Cart abandoners: added to cart, no purchase within 1 hour (streaming).
- Loyalty members browsing a category this session (edge).
Step-by-step validation
- Write the business definition in plain language first.
- Build the rule and check the estimated audience size.
- Inspect sample qualified profiles to confirm the logic.
- Check the merge policy and identity behaviour behind the audience.
- Monitor qualification counts after activation.
