Term	Type	Available report type

Estimated earnings Your account balance for the time period selected. This amount is an estimate that's subject to change when your earnings are verified at the end of every month.	Metric	User activity report Bidding report Ads Activity report
Impressions The total number of ads shown to users. Note: When a third-party waterfall ad source serves a banner ad, AdMob counts an impression when the third-party adapter sends the ad load callback. This may cause discrepancies in reported impressions between AdMob and your third-party ad source. For example, if you preload banner ads that aren’t shown immediately, you may notice higher impressions reported in AdMob.	Metric	Bidding report Ads Activity report
CTR (%) Impression click-through rate (CTR) is the number of ad clicks divided by the number of individual ad impressions. It's calculated by dividing clicks by impressions: `(Clicks / Impressions) * 100%` For example, if your ad received 20 clicks out of 1,000 impressions, the Impressions CTR would be 2%.

Serving restriction Use this dimension to compare personalised ads to non-personalised ads, and understand which restrictions lead to ads not being personalised: Limited ads: Traffic where limited ads were served, regardless of user location. Restricted data processing (RDP): Publisher chose to enable restricted data processing (for example, using AdMob’s blocking controls) for compliance with the California Consumer Privacy Act (CCPA). Non-personalised ads (NPA): Publisher chose to enable non-personalised ads (for example, using AdMob’s blocking controls) for compliance with Google’s EU User Consent Policy and GDPR. Also applies to ad requests subject to the LGPD. Basic ads: IAB TCF v2.0 basic ads were served. Personalization disabled: May occur when iOS users have opted in to Limited Ad Tracking or haven’t provided consent under the AppTrackingTransparency (ATT), and there's no other available user identifiers. May occur when Android users opt out of ad personalisation. Includes any other cases where personalisation wasn’t feasible. No restriction: Ads that are personalised using IDFA, Android Ad ID or other available user identifiers. Some ad requests may fall into multiple categories in this list. In these cases, the ad request is sorted into the first applicable category according to the order shown here. Available for date ranges starting on or after 13 March 2021.
