Using Your Domain Name with Google Apps
Your Go Daddy domain name can easily be set up for use with Google Apps®, but before you can activate your services, Google and Go Daddy need to verify that you own your domain name. By verifying your ownership, you can configure your domain for use with Google Apps. You’ll also be able to route your domain-based email for use with Google Apps.
Go Daddy is a Google Apps-Ready registrar, which makes the process of verifying domain ownership simple. All you need to do is log in to your Go Daddy account through Google, and authorize Google Apps to work with Go Daddy to verify your domain ownership.
When your ownership information is confirmed, Google will automatically configure your domain name so it can be used with your Google Apps services and email.
