Mitigate loss of registrations by only showing the payment page to those trying a paid plan.
LucidChart segments users during the registration process and only passes the high-quality ones through the payment page. They do this by predominantly displaying their paid levels and then showing a free option below, see here: https://www.lucidchart.com/users/registerLevel.
Users who click on standard levels see a payment page, users clicking on free do not. This has helped them mitigate the registration loss because of a payment page.
