An A/B test is only useful once you can trust its answer. Attravo shows each version's results side by side and names a winner only when the difference is unlikely to be chance.

## Find your tests

1. Open **Performance**.
2. Pick the funnel in the funnel picker at the top. Tests appear under **A/B tests** for one funnel at a time.

## Read a test

Each step being tested has a row per version:

- **Offers shown**, **Accepted**, **Rate** and **Earned** for that version.
- **Change**: how much more or less it earns per offer shown than version A, the control.
- **Verdict**: **Control** for version A, how confident Attravo is in a leading version, or **Too close to call**.

The step's badge says **Version B is winning** when a winner is called, or **No clear winner yet**.

A winner is called only once both versions have enough traffic and the difference is 95% unlikely to be chance. Until then, the honest answer is that it is too early.

## Act on the result

When a version wins, make it the only one: open the offer, remove the losing versions under **Versions**, and save. **What to do next** suggests this too when a test is decided. See [Act on What to do next](https://help.attravo.com/post-purchase-upsell/articles/act-on-what-to-do-next.md).
