Google Analytics is a tool by Google that collects and creates reports that provide insights into your business.
The insights comprise information like the number of visitors, and their behavior, purchases, location, and numerous other information to help users optimize their marketing strategy.
You need to add a small piece of JavaScript measurement code to each page on your site, after which every time a user visits a webpage, the tracking code will collect pseudonymous information and send it to generate the report to Google Analytics.
