AdMob question.

[Pennywapps AndroidDevs]

Hi guys, i was watching our Admob stats. there is a thing that is not clear for me. i searched on google but it's not clear at all.



As you can see there is a big difference between Request and Impression. a rate of 21%
can anyone tell me why?

ty guys!

Requests are the number of request from the user while Impression is the number of ads shown. Many devices requested ads but only a few of them can show the ads, maybe because of slow connection.
