We recently launched an improvement to Google Apps that made dozens of Google services, including AdSense, available to Apps users for the first time. Before this improvement, Google Apps users had to create a separate account to sign in to AdSense; now, Apps users can access their cloud-based productivity applications along with AdSense using the same account.
For those of you who also have a Google Apps account, we're in the process of finalizing the infrastructure that will allow you to seamlessly transition your existing AdSense account and data over to your Google Apps account. For new users, if your Apps systems administrator has enabled AdSense, you can begin using this services with your existing Apps account at google.com/adsense.
If you haven’t started using Google Apps yet to manage collaboration for your business, learn more about how to lower IT costs and improve productivity at google.com/apps.
