About ABI Game Studio
The Objective
Like many publishers operating in the competitive mobile gaming landscape, ABI Game Studio faced monetization challenges that were limiting the revenue potential of their titles, including flagship game Foodie Sizzle. Their existing monetization stack lacked the infrastructure needed to convey high-quality audience and contextual data to demand partners, resulting in systematically undervalued impressions across all key ad formats. With ABI Game Studio operating a diverse network of demand partners co-bidding on their mediation stack, signal quality and auction fairness became critical. They thus needed a trusted partner that could activate rich publisher signals at scale and unlock the true value of their inventory across global markets.
The Solution
ABI Game Studio implemented Publisher Passed Signals (PPS) via InMobi Exchange on Foodie Sizzle, partnering with InMobi Advertising to leverage its deep expertise in the regional gaming ecosystem and access to a diverse pool of premium global and regional advertisers. Having been an InMobi SDK partner for over four years, ABI had a strong technical foundation from which to scale PPS across their key ad formats: Banner, Interstitial, and Rewarded Video.
#1: Activating High-Quality Signal Infrastructure Across Formats
InMobi Advertising worked with ABI Game Studio to activate Publisher Passed Signals across Banner, Interstitial, and Rewarded Video placements. By surfacing rich, first-party audience and contextual signals to demand partners through InMobi Exchange, ABI was able to accurately represent the true value of their inventory, enabling buyers to bid with greater confidence and precision. This directly addressed the long-standing undervaluation of impressions that had suppressed eCPM performance across Foodie Sizzle’s global traffic.
#2: Ensuring Fair and Addressable Bidding Across a Multi-Partner Mediation Stack
With multiple demand partners co-bidding on ABI’s mediation, signal consistency and quality were essential for a fair and efficient auction. InMobi Exchange’s PPS implementation ensured that all bidding partners received standardised, high-quality signals, creating a level playing field and maximizing yield for every impression. Interstitial placements achieved 95.5% MRC viewability, reinforcing the premium nature of ABI’s inventory and driving stronger demand competition.
The Results
The impact of PPS activation was immediate and consistent across all major ad formats. Within weeks of going live on InMobi Exchange, Foodie Sizzle recorded significant eCPM uplift across Banner, Interstitial, and Rewarded Video, validating the direct link between publisher signal quality and inventory yield. Banner placements, which benefit most from improved audience addressability, saw the strongest uplift.
