Yes, if you would like to track statistical data on your website (i.e.: number of visitors, age, location, etc.), you can include a Google Analytics tracking code in your website. The tracking code itself is provided by Google so you will need a Google Analytics account.

In Google Analytics, you can find your websites tracking code by clicking on the "Admin" tab at the very top and then clicking on "Tracking Info" - "Tracking Code". Your tracking code should look similar to the example below.

Example code only:

(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
ga('create', 'UA-78722-17', 'auto');
ga('send', 'pageview');
Note: You will need to enable the “Show Search Engine Optimization Options” found under “Business Settings” > “Options” before the tracking code area is available.
  1. Navigate to "Website" from the main menu on the left. 
  2. Select the "Settings" tab.
  3. Copy your tracking code and paste it into the "Tracking Code" space.
  4. Click "Save Settings".
