How to Create Admob Account (After Adsense)

Complete the following steps if you already have an AdSense account associated with the Google Account you're using to sign up for AdMob:

1. Go to https://apps.admob.com.
2. Click Sign up with your Google Account to sign up for AdMob with the Google Account associated with your existing AdSense account. Follow the on-screen prompts to sign in with this account. 
3. Review the AdSense account information that was automatically imported into AdMob. 
4. Complete the account information to create your new AdWords account:
   1. AdWords billing currency: Select the desired currency. This is the currency you will use to pay Google if you decide to use AdWords to run paid campaigns. It can't be changed later.
   2. Time zone: Select your time zone. We recommend setting the same time zone for your AdWords and AdSense accounts to ensure accuracy in reporting data. 
5. Check the checkbox to confirm that you've read and agree to the program policies, AdSense Terms & Conditions, and AdWords Terms & Conditions.
6. Click Create AdMob account.
