And then click on new account to add your first website, it looks like this:
Once you click New Account, you will enter in the information for the website. Such as a Account Title, this can be something like “Your Website” and then it will ask you for the website URL. With a drop down for “http://” or “https://”, if you have SSL you select the “https://” if you do not know what this is then you most likely have “http://”. Next to that you just enter in YourWebsite.com, the www is really not needed and you may see an example below:

And a pop-up will appear, just paste the code you copied from the Analytics page into the bottom box that says Addition head tags:
Once your done hit ok, and then click the floppy disck icon on the top right to save. Or you can hold CTRL and hit S to save as well
