A/B testing of your landing page helps you experiment with more than one variant of a landing page for the same campaign and identify which one works best for you.
Run A/B Tests
In the Variants panel, you will find 2 modes namely the Standard and the A/B testing.
Enable A/B testing by switching the mode in the dashboard
In this screen, you will find an option to adjust the weightage of each of the variants. Based on the weightage, each of the variants will be served to your audience. For example, if you set the weight for Variant A to 65% and the weight of Variant B to 35% and if you totally had 100 visitors - Variant A will be served to 65 of them and Variant B will be served to the remaining 35.
You can monitor how each of your variants is performing in the Analytics tab. Follow the link to know more about Analytics.
