How to set up A/B testing on legacy landing pages?
The A/B testing
To set this up, open the landing page editor. In the top left you will see a drop down list with a default “Variant A” setting. Click + to create more variations for your test. To remove the variant click the trash icon (you can do it before saving the landing page for the first time, later the trash icon will not be available).
The result of your tests will be available on Manage landing pages. To check the stats, navigate to the landing page and click the A/B icon.
Take a look on the right side of the screen, there you can find the sign-up ratio. To publish the most successful one as a winner click the Actions icon (vertical ellipsis). Right away you will see the trophy icon beside it. The other variants will be automatically disabled.
If at any point you want to remove one of the variants after you save the landing page, you need to click Turn OFF button under the Actions.
