To help understand your website visitors behaviour and to see the most popular pages and content, it's a good idea to use Google Analytics.
This free service from Google is the worlds most popular tracking and analytics tool, offering insights into every aspect of visitor behaviour.
To add Google Analytics you'll need a Google account and the tracking ID. To find your tracking ID it's probably best we let Google themselves tell you how by reading this.
Once you have your account and code you'll need to add it to your site. This is the easy part, click "Site Settings" from the Side Menu and "Google Analytics" then paste your code in the input. Then to make the code you'll need to "Publish" from any page.
