As a webmaster you have many websites to keep track of and numerous third party application accounts to log into, but with Google Analytics, using many accounts isn't that painful. Google Analytics allows you to add multiple account under one main Google Analytics account. In this tutorial, I will show you how to create a Google Analytics account under your main account and then give the website owner permission to login and manage his 'sub account'.

1.  Sign into your Google Analytics account.
2. Click on the 'Admin' tab.
3. Click the 'New Account' button.

5. Click the 'Get Tracking ID' button.
6. Click the 'I Accept' button and accept the 'Google Analytics Terms of Service Agreement'. 
7. The note should say:"Status: Tracking Not Installed

   The Google Analytics tracking code has not been detected on your website's home page. For Analytics to function, you or your web administrator must add the code to each page of your website."

   Paste the tracking code into the website's markup and refresh the page and the status will change to:

   "Status: Tracking Installed"

14. Check the 'Administrator' bullet.
15. Checking the 'Notify this user by email' box will send the new user this email:
    " Hello, We want to alert you that you have been added as an administrator to the Google Analytics account "mywebsite.com (UA-39104213)" by info@myemailaddress.com.
