# How to run two paywalls inside one campaign and know which one that channel pays for

Test two paywalls in one campaign and see which one converts more trials to subscriptions on each channel. Run one ad per paywall in the same campaign and ad set, and name each ad after its paywall. Your developer needs to set up the app so that each ad's link opens the matching paywall. In the Funnel report, group trial-to-subscription conversion by **Channel** and **Ad Creative** to compare Paywall A and Paywall B. To compare how much ad spend each paywall earns back, see [How to check whether the winning paywall still pays back the ad spend that bought it](https://help.airbridge.io/en/guides/how-to-check-paywall-payback-on-ad-spend.md). To set up this report step by step, watch the video.
