Does the admob appId actually matter?

Getting Started Newbie Questions
#1

I just realized in all our apps for the appId I’ve been using the adUnitId instead of the actual appId. All our ads are showing revenue, impressions etc etc. I’m just wondering if the appId even matters and if so what’s it used for?

#2

Their official documentation states that appID should be used when initializing their SDK, and adUnitId be used when requesting ads.

IIRC the behavior of only using the AdUnitId stems from their legacy implementation, and they still happen to support it for legacy apps.

Any new apps should use their official implementation and use appId and adUnitId where appropriate.
