About Pocket FM
The Objective
As Pocket FM’s global audience expanded, the team sought to scale monetization across its app portfolio while preserving the immersive experience it offers. It needed a monetization partner that could deliver strong performance at scale while maintaining a high-quality user experience, with full-screen ad formats playing a central role in its revenue strategy.
The Solution
Pocket FM partnered with InMobi Advertising to elevate the performance of its ad inventory through an SDK-driven monetization approach across its app portfolio. Rather than simply increasing ad volume, the focus was on making every impression more valuable to demand partners by improving how ads were rendered and experienced. This aligned closely with Pocket FM’s UX-first philosophy, enabling revenue growth alongside sustained user engagement and retention.
#1: Strengthening Supply Through SDK-Driven Monetization
By integrating the InMobi SDK, Pocket FM unlocked richer, privacy-safe signals and greater transparency at the source. This SDK-first integration enabled Pocket FM’s inventory to be evaluated more accurately by demand partners, positioning it as a high-quality, preferred supply within the auction. Monetization was further strengthened through a robust bidding and mediation strategy. Pocket FM leveraged the InMobi SDK across both in-app bidding and waterfall setups, while accessing diversified demand through leading partners such as Google Ad Manager, AdMob, Google Open Bidding, and Unity LevelPlay. This combination drove stronger auction competition, improved yield, and more consistent monetization performance.
#2: Optimizing Full-Screen Ad Experiences at Scale
InMobi Exchange’s full-screen ad formats enabled Pocket FM to monetize high-attention moments while maintaining an immersive and engaging user experience. Interstitial and rewarded ad experiences were optimized to align naturally with content consumption, with adaptive rendering ensuring each ad appeared visually integrated, user-first, and contextually placed.
By activating in-app banner, interstitial, and rewarded video formats, Pocket FM diversified monetization where InMobi’s ad experience and global demand capabilities delivered the strongest impact, driving revenue growth while supporting long-term engagement.
The Results
Pocket FM achieved sustained monetization growth across its app portfolio by elevating the quality of its supply and scaling experience-led ad execution across key ad formats.
