Google AdMob is a software platform from Google to place advertisements to your applications that you have built. Advertisements are usually from Google Ads or other advertising platforms. The main purpose of AdMob is to earn revenue (money) through apps you have created and published to app stores. Ads from AdMob allows you to choose the different format of Ads which includes interstitial ads, banner ads, rewarded interstitial ads, rewarded ads, Native advanced ads and App open ads. You may customize the position of the ads to your liking. I would say Google AdMob is quite similar to Google AdSense which also allows you to earn revenue through websites.
Google AdMob is also similar to Facebook advertising as well, the best platform to create apps and adding ads is Kodular Creator, Kodular is a platform that requires no coding but using drag and drops functionality. You can also connect Firebase to AdMob to view where audiences are clicking ads in your apps. It is also a good practice not to place so many advertisements in your apps as it may reduce the number of people visiting your app.
Do not be so greedy for money by placing so many ads, just place the right amount of 2-3 ads on a page.
