AppLovin mediation waterfall really low eCPM

[Robin S]

Hello,

My mediation setup through AdMob is the following one:

- Vungle, AppLovin, Admob, AdColony as bidding source

- AppLovin waterfall

- AdColony waterfall

I get ads and everything seems good but I don't understand why my AppLovin eCPM is so low compared to the others sources: did I misconfigured something?

Thanks in advance,

Robin

Hello,

Thank you for reaching out to us. Let me do the best I can to assist you in this.

With regard to your concern, please do note that the mediation waterfall ad-serving depends on the configuration. When an ad impression becomes available, ad server calls demand sources one by one. Usually, setting the impression of the mediation network to 100% (also setting the eCPM very high) will force to display it. In addition, the SDK just request an ad to the ad-server and don't have any control on the ad it will receive. On your case, this is more of an ad serving concern which I'm afraid out of our scope. What we can suggest at this point is to reach out to Product support team as they are more equipped in handling ad serving concerns.

Hello,

Thank you for your answer.

I still have a question about the eCPM that I can input in the Mediation page: for example, if I set a eCPM to 10$ for AppLovin waterfall, does that mean that if an ad request is filled by AppLovin, the eCPM will be capped to 10$? Or is it just a way to sort different sources?

Thanks in advance,

Robin
