Quick ad lesson here:
In the late 1990’s and early 2000’s, online advertising didn’t really get how it works. They operated on the TV model of show the ad and you could measure success in your brick-and-mortar store the next day (Come to Toyota tomorrow for 20% off). Other TV ads existed just to build brand awareness. So with this model, advertisers paid for just showing ads. They paid per 1000 ads shown or known CPM or Cost Per Mill.
It wasn’t long before the advertisers learned that they were not getting the “view” engagement, especially in games where no one would actually engage with a banner ad. So the model changes to what’s known as CPC or Cost Per Click. You got paid only when the ad got interacted with. Eventually, they learned that wasn’t all that effective, in particular with mobile apps because clicks didn’t turn into sales. so the advertisers turned to a new model: CPI or Cost Per Install. This is what most interstitial ads are today.
I said “most” because you can still make some money for showing banner ads in a CPM manner, not much mind you. There are still advertisers who do pay CPC. This will be more common than getting paid for just showing banner ads, but it’s still not going to be your best engagement. CPI campaigns pay the best. This is what most interstitial ads are (static image or closeable video). Interestingly enough, all models are converted to an eCPM (effective CPM) to allow all campaigns to all be measured against each other.
Rewarded video is a non-closable video ad. The ad provider pays more for this because they know the user has requested to view the ad and they will see the whole ad. This is much closer to traditional TV advertising and this pays the most, but it’s also the most limiting because you can only show them if the user asks to see the ad and you must be able to give them some in-game/in-app value for viewing the ad.
