The eCPM of Our AdMob Account's Banner and Reward Ads Suddenly Decreased by over 95% Starting from March 22nd

[feifei mian]

The eCPM of our AdMob account's banner and reward ads suddenly dropped by over 90% starting from March 22nd, causing a significant decrease in revenue that cannot cover our costs.

We did not receive any notification emails from AdMob and did not violate any of their policies. This incident has left our team feeling particularly discouraged as we do not know what we did wrong.

Could you please help us investigate the reason for this? What should we do?

Best regards.

Hello Feifei,

Thank you for reaching out to us.

I'm afraid eCPM, match rate, and impression issues are dealt with in the AdMob Help Center. For revenue-related concern and performance of ad units, we recommend that you reach out to the Product Support Team as they're the appropriate team that could help you in this. You may check this Advanced techniques to optimize in-app revenue with Google AdMob guide and optimization tips that can help you regarding this. Kindly note that the SDK just requests an ad to the ad server (E.g: AdMob), and I'm afraid that it doesn't have any control on eCPM, fill rate, match rate, or impression of your app. This forum can only provide support on the technicalities related to the code implementation of the Mobile Ads SDK.

Regards,

Mobile Ads SDK Team
