Admob: big drop in request/impressions, but big increase in RPM

Hello,

I notice a big  drop in request/impressions , but a big increase in RPM in my AdMob banners. It started between 26 and 28 of October.

It is like 3x fewer impressions, but the RPM is like 3x more…

I am really worried if it is a glitch or something more serious…

Anyone experienced it too?

Thanks

Sounds like a good thing to me, but maybe I’m misunderstanding. 

1/3 as many impressions, but 3 times the return == 1;

Sounds like some kind of house cleaning and/or fraud fix.

It is a little strange. For 2 years I have more or less 80.000 impressions per day.

Now we have 25.000. But the RPM increased from 0.6 - 1 to 2.2 - 3.5.

Is that normal? I work for 2 companies. And in both companies that happened on the same dates (between 26 and 28 of October)…

Best regards,

I see it also. It is very strange. Has anybody been able to figure it out?

Last week, 

I noticed this as well but it ramped back up to my usual amount by friday.  RPM was definitely up those days, and I was experimenting with mediation groups.  When I paused it through the admob site, impressions went back to normal the day or two after.  Could have been a coincidence though.  

@noriega did you update your app? I just noticed that if I open up my app the banners do not refresh even when configured on the Admob website to refresh every 60 seconds.

yeah I did, that could be a reason as well. Perhaps the banners were cached before the app was updated… and then erased when the app is updated? It could take a little bit of time to be re cached… I’m just guessing that’s how caching works in regards to the admob plugin.  I’ve just started going more in depth into native android but haven’t looked at the native admob codebase yet.
