# Experiment paths

> Split a journey into 2 or 3 random paths, compare their conversions and revenue, and send everyone down the path that wins.

Source: https://docs.grovs.io/docs/engagement/journeys/path-results

A **Split** step set to **By percentage** sends people down 2 or 3 random paths. Each path is a variant of the journey from that point: a push against an in-app message, a one-day wait against a three-day wait, a discount against none. The report compares the paths so you can keep the winner.

## Set up a path experiment

### 1. Add a percentage split

In the journey editor, add a **Split** step and choose **By percentage**. Give each path a share. Shares add up to 100%, and each path needs at least 1% before launch. **Add a path** adds a third.

### 2. Build each path

Add the steps that make each variant different. Paths can rejoin further down, so only the tested part needs to differ.

### 3. Add a goal

Path results measure the journey's first goal. Without one, paths can't be compared on conversions. See [Set goals](https://docs.grovs.io/docs/engagement/journeys/build-a-journey).

### 4. Launch

Each person reaching the split takes a random path by share, and always takes the same path if they reach that split again.

## Read the results

Each percentage split gets a card on the journey's **Results** tab once someone has taken one of its paths. Paths are labelled Path A, B and C, in their order on the split.

| Column         | Shows                                                                                        |
| -------------- | -------------------------------------------------------------------------------------------- |
| **Group**      | The path, with its share                                                                     |
| **People**     | People who took the path in the period                                                       |
| **Converted**  | People who reached a goal within the first goal's window after taking the path, and the rate |
| **Revenue**    | Their store purchases in the same window                                                     |
| **Per person** | Revenue divided by people                                                                    |
| **Confidence** | How sure the conversion-rate difference from Path A is real                                  |
| **vs A**       | The difference from Path A                                                                   |

A sentence above the table names the leading path: by revenue per person when anyone bought, otherwise by conversion rate.

- **Only people who reached the split count.** Anyone who left earlier, or reached a goal before the split, is in no group.
- **Path A is the baseline.** Other paths are compared with it. Path cards have no control group; the journey's control group is compared on the journey's goal card.
- **Confidence needs people.** It shows once both compared paths have at least 100 people, and covers conversions only, not revenue.
- **The window** is the first goal's window. Without a goal, revenue counts for 72 hours after the split.
- **Changing shares later** doesn't rewrite history: each person counts under the path they took.

Journeys that ran before experiment paths existed (2 October 2026) recorded no paths and have no path cards.

## Send everyone down the winner

When a path leads, its card offers **Send everyone here**. Confirming sets that path to 100% and the others to 0%:

- Everyone reaching the split from then on takes the winning path.
- People already past the split stay where they are.
- You can change the percentages back in the editor.

If the lead isn't clear yet, the confirmation warns that there aren't enough people. A lead is clear when its conversion confidence is at least 95% and, if people bought, the top earner per person also converts best. With three paths, confidence is only measured against Path A, so a lead by B or C is never treated as clear: a close third path can't be ruled out.

You can also set percentages yourself in the editor. After launch, a path can go to 0% as long as the others add up to 100%. Paths can't be added, removed or reconnected after launch.
