  You have successfully set up InMobi as a bidding source in your AdMob mediation groups. You have integrated the InMobi SDK and the corresponding AdMob adapter. Your dashboard shows "Active," yet your fill rates are abysmal, or the eCPM is suspiciously static. In 90% of cases, this is not an issue with your traffic quality or the InMobi demand. It is a configuration silent failure. Modern programmatic bidding relies on passing encrypted data objects—"signals"—from the client device to the mediation server. For InMobi, Google AdMob requires an explicit opt-in for these signals to be ingested. Without enabling "Secure Signals," the InMobi bidder receives a bid request without the necessary context to value the impression, resulting in a no-bid or a floor-price bid. This guide details the technical root cause of this failure, the mandatory UI configuration to fix it, and the code required to ensure the signal pipeline remains open. The Root Cause: The Opaque...

  Mobile publishers operating in the EEA (European Economic Area) frequently encounter a silent revenue killer: low fill rates from mediation partners despite having a fully compliant Consent Management Platform (CMP). One of the most common friction points occurs between Google AdMob and InMobi. While AdMob’s User Messaging Platform (UMP) correctly collects TCF v2.0 (Transparency and Consent Framework) signals, the InMobi adapter does not always automatically ingest these signals from the device's shared preferences. If InMobi does not receive an explicit consent object, it defaults to a non-consented state. This results in the rejection of personalized ad requests, plummeting eCPM and fill rates. This guide details how to manually construct the required JSON consent object and inject it into the InMobi SDK to ensure revenue continuity. The Root Cause: Implicit vs. Explicit Signaling To fix the issue, we must understand the disconnect in the mediation chain. When a user grants con...
