There are 3 approaches you can take to finding the highest converting messages for your products.

1) You can trust that your current message is the best one possible, and hope that you're right.

2) You can do traditional A/B testing. Pit 2 variants against each other for a day or a week, send traffic to both, and then keep showing the highest converting one. Keep doing this for every variant you want to test.

3) Instead of split testing variants one by one, throw them into the ring together, only showing the description with the highest conversion percentage at the moment a new visitor comes to the site. This way, you'll never be wasting traffic - everybody is seeing the highest converting descriptions. If a description starts to underperform, then it will be replaced quickly.

With this app, you can do the third one. Since you know you’re not going to waste any traffic, you can test an order of magnitude more variants than you would with A/B testing, to continually push your conversion rates up without risking losing traffic to underperforming test cases.
