How AdMob works

AdMob provides a way for Google to help app developers earn more money from their apps. AdMob works by matching ads to your app based on criteria you set. The ads are created and paid for by advertisers who want to promote their products. Since these advertisers pay different prices for different ads the amount you earn will vary.

About AdMob

What is AdMob?
AdMob is a free platform that gives you a way to earn money by displaying targeted ads alongside your app content. You can show relevant and engaging ads to your app users and even customize the look and feel of ads to match your app.
How does AdMob differ from other mobile ad platforms?
AdMob brings together best-in-class technology in a single platform, so you can gain insights about your users and help maximize your ad revenue. No longer will you have to rely on a combination of tools or use precious development resources to build your own solution. With AdMob, you can make money from the ads shown in your ad units, use house ads to cross-promote your own apps, and run direct deals for clients all in one place.
Do I have to choose which ads to show in my app?

No. AdMob automatically serves ads to your apps from the AdMob Network and third-party networks of your choosing. These ads can be targeted to your app content and audience.

If you do want control over what appears in your app, you can block ads from certain advertisers and categories from being shown in your app.

Who decides which ads to show in my app?

AdMob uses an ad auction to automatically select the ads that will appear on your pages from all the available ad sources. Generally, the highest performing ads will be shown in your app.

If you do want control over what appears in your app, you can block ads from certain advertisers and categories from being shown in your app.

Can I choose the design of the ads in my app?
Yes. You can choose from a variety of ad formats and types to fit your app.
Can I see the ads in my app?
Yes, when you've got your ads up and running, you'll be able to see them in your app. However, an important thing to remember is not to click on your own ads. Clicking your own ads for any reason is not permitted by the AdSense program policies and can result in the termination of your account..
If I see an ad in my app that I don't like, can I remove it?
Yes. The Ad review center and blocking controls in your AdMob account let you review individual ads and choose whether to let them be shown in your app. Check out our guide to allowing and blocking ads in your app.


Do I have to pay to use AdMob?
No, using AdMob is free. Even better, Google and any third-party ad networks you use will pay you for clicks, impressions, and other interactions with the ads you display in your app.

Does AdMob have policies for participation that I must adhere to?
Publishers who choose to use AdMob are required to adhere to both AdMob and AdSense policies. If you fail to comply with these policies, we may disable your AdMob account. In many cases we prefer to work with publishers to achieve policy compliance; however, we reserve the right to not display ads that violate these policies, to disable ad serving on pages that violate these policies, to withhold payment, or to close offending accounts.

Please note that we may change our policies at any time, and pursuant to the AdSense Terms and Conditions (which apply to AdMob users), it is your responsibility to keep up to date with and adhere to the AdMob and AdSense policies.

How do you enforce the program policies?
We actively monitor AdMob publishers to check for continued compliance with our AdMob and AdSense policies. If we find publishers that do not comply with our policies or the AdSense Terms and Conditions, we may suspend or terminate the account.
