Viewing the Tracking Codes in Your Page's Source Code

3 min read
A tracking code is a piece of javascript code in the source code of your site's pages. Many tools can use these tracking codes to give you insights into how your site visitors interact with your pages. 
For example, Google Analytics uses a tracking code in the first section of your site's code (known as the header) to track information such as how many people are visiting your pages, where they visit from, and what device they're using.
You can view the active tracking codes on your site by viewing your page's source code, changing the user agent in your browser's settings, and then filtering the result. The user agent helps identify which browser you're using. When you select a web crawler bot such as Googlebot as your user agent, you can view the exact content that the bot crawls and see any tracking codes that are present.
