## 1. Open A/B tests and choose what to test

**1. Which bundle? 2. What do you want to test?** the discount, the title & texts, the design, or the products. **3. How many shoppers see version B?** half and half is recommended. Then click **Create version B**. Nothing changes on your store yet.

## 2. Make your change in version B, then Start A/B test

Version B opens in the editor as a copy. Change only the one thing you test, so you know what made the difference, then click **Start A/B test** at the top right.

## 3. Read the results

The results page tells you in plain words who is ahead and how sure we are: revenue per visitor, shoppers who saw each version, adds to cart, orders and revenue. Let it run at least a week and don't change either version meanwhile.

## 4. Keep the winner

Once a version is ahead with 95% certainty, click **Keep version A** or **Keep version B**. If B wins, its settings are saved into your bundle and the test ends. You can also end a test at any time.
