Experiment Node
Split users in real time with percent-based or count-based experiments.
Experiment nodes split users into variations for A/B testing. In real-time journeys, percent-based and count-based experiments assign variations instantly as events arrive.
Supported experiment types
| Type | Lightning bolt | Behavior |
|---|---|---|
| Percent split | Yes | Deterministic bucket per user — same user always gets the same variation |
| Count split | Yes | Assigns variations in order until quotas are met |
Configure an experiment
- Drag an Experiment node onto the canvas.
- Choose Percent or Count split type.
- Define variations and allocation (percentages or fixed counts).
- Connect a downstream path for each variation.
Each variation can have its own custom attributes and downstream nodes.
Use with same-session personalization
Combine experiment splits with a Personalization API destination to write different offers or flags per variation, then fetch the profile on your website or app. See Same-session personalization for a full walkthrough.
