AdSense is a Google service that allows you to display advertisements in your YouTube videos so that you can earn money. If you create an AdSense account before or during the application process it will allow you to receive money faster. You will be able to create or link an AdSense account at any time, until then your money will be stored on your account and will be accessible once you have an AdSense account. This way you do not lose any of the money you have earned.

To sign up for a AdSense account, please go to www.google.com/AdSense - and click "Get started now" - here you will need to submit your application for a AdSense account. Google should approve your account within 24 hours. They will notify you about your application via email. So make sure you pay attention to the emails you receive. (Note: you can create a separate Google account for your AdSense account - you will have a choice on the website)

Once Google accepts your AdSense application, you will need to associate the AdSense account with your YouTube channel.
