Collapsible banners boost Device Info's eCPM by 50%

Xiao Bin, creator and individual developer of Device Info, faced stagnant revenue growth from his current ad monetization strategy. With limited time for operational optimizations, an efficient solution was needed to boost ad performance and break through the monetization plateau.

To tackle this, the developer implemented AdMob collapsible banner. This responsive ad format, which initially occupies half the screen before collapsing to a standard banner size, minimized development time and cost by requiring only a few extra lines of code for implementation. The format's effectiveness was confirmed through a straightforward A/B test using Firebase Remote Configuration, allowing for a direct performance comparison against the traditional banner in a live user environment.
