Hi Kuan, I can see that the total RPM for your account is $0.97. Is this changed after you have reported it here?

Hi Kuan, RPM = (Estimated earnings / Number of page views) * 1000 You can see now that the value depends upon 2 other factors what are also variable. Since your RPM dropped for only few days and has gone up again to normal value, I am not considering it as concern. If the same thing repeats in future please get back to me I will try to get that clarified from the concerned team. Thanks.

Hi Kuan, We got your case clarified by internal appropriate team here and they said eCPM and fill rate changes happened due to the advertiser mix on our network. So it seems that the Ads back end is tuned some what for optimal filling.

There are many factors that influence eCPM such as app content, ad placements, and advertising campaigns that match your user base. As a result, every app will see different performance.

Hi Kuan, Yes, I can see your Ads Performance Report and it's unfortunate that your earning has gone down > 50% We have already clarified your case from the internal appropriate team here. We have made some internal changes (advertiser mix on our network) for optimization. As a result eCPM and fill rate changes happened for a number of developers like you. I am sorry to say that I can not help on this any more. Very Sorry!!
