How do I create a Google AdSense account?
If you have a Google Account, you may already have one. You can check by visiting the AdSense page while logged into your Google Account.
If you don't have an AdSense account:
Register an account on Blogger, Google's blogging service, here. If you already have a Google Account, you don't need to register a new one to do this.
Apply for AdSense by following Google's instructions here.
The application process can take up to a week.
