Finding the code can be tricky, we suggest checking out this article, but in short, you copy a piece of code to the tracking section of your website (in the Website Builder area of the PhotoBiz control panel), or you can add it to individual pages, forms, and even marketing campaigns.
Once the tracking data is on your site, your Google Analytics dashboard data will start to record metrics for your website. The data collected is very diverse. It includes behaviors, like how people search on your site, what pages they visit, and even how long they stay on a page before they exit or bounce.
