1. Create an adwords account

To login to AdMob you need a Google Adwords account. Create one first at http://adwords.google.com

2. Create your AdMob account

Login to AdMob at https://www.google.com/ads/admob/ and create your account after choosing your Adwords account

3. Create your ad

Once logged in Admob, you reach this page:

Click on “Apps” and on “ADD APP“:

Next, if you published your app, click on “YES“, you will have to search for your app on the stores. If “NO“, enter an “App name” and select the platform on which you want to publish your app:

Click on  and choose from interstitial or banner (rewarded is not supported). Give a name to the Ad and click on “CREATE AD UNIT“:

Note down the ad unit ID:

You can repeat the same process to create another kind of ad, or the same kind of ad but for another kind of system/device.

4. Add your ad unit ID to your app

Go to your Editor, in the Publication tab of your app.

Check “Monetize my app using AdMob?” and enter the ad unit ID you just created:

Now you are ready to display ads inside of your app and make money with it.  Be sure to publish your app after completing all of these steps. You can not publish your app first and follow these steps afterwards. Because we need to integrate your admob accounts into the source code of your app!
