Instructions for adding tracking
Copy the following code block into every webpage you want to track.
Click in the box below to select all code. Copy and paste the code segment into the bottom of your content, immediately before the </body> tag of each page you are planning to track. If you use a common include or template, you can enter it there https://www.google.com/support/analy...26908&hl=en_US
