Besides, what is impression rpm in AdMob?

Revenue per 1000 impressions (RPM). RPM doesn't represent how much you have actually earned; rather, it's calculated by dividing your estimated earnings by the number of page views, impressions, or queries you received, then multiplying by 1000.

Furthermore, is AdMob CPC or CPM? Admob is CPC primarily. Apparently a small amount of campaigns are run via CPM, but it's always CPC on the publisher's side. DO NOT USE inMobi.

Hereof, how much does AdMob pay per impression?

CPM is around $1, or $1 per 1000 Ad impressions. Clicks I have seen as high as $0.25, but its going to vary on the Ad shown obviously. Essentially my rough guide on income per active user per day based on my very limited experience: Assuming each user will go through 10 impressions per day/play session.

Why is AdMob matching rate so low?

There is no one reason for the low match rate. There are many players in between an ad request and serving the ad to the user. 1: No Advertiser/ DSP server might have responded or responded with an ad which is broken to the ad request from the app.
