2. How Google AdMob Works

Google AdMob works as a middleman between advertisers and app developers. Advertisers pay to display their ads on apps, and developers earn revenue when users view or interact with these ads.

2. Integrate SDK: Developers integrate the AdMob SDK (Software Development Kit) into their mobile apps.

3. Choose Ad Formats: Developers select ad types that best fit their app (banner, interstitial, rewarded, etc.).

4. Monetization: Ads are displayed in the app, and revenue is generated based on user actions.

5. Payment: Google processes payments through AdSense after you reach the payout threshold (usually $100).

Revenue Models:

• CPM (Cost per Mille): Earn revenue for every 1,000 ad impressions.

• CPC (Cost per Click): Earn revenue whenever users click the ad.

• CPI (Cost per Install): Earn revenue when users install apps from your ad.

• CPA (Cost per Action): Earn when users complete a specific action like signing up.
