How does Google Analytics work?

When a visitor accesses a page on your site, a request is made to the webserver to display the page.

The page is served and the Google Analytics Tracking Code JavaScript is executed.

The Google Analytics Tracking Code, which is a snippet of code that you place on each page of your site, calls the trackPageView() method.

At this point, the Google Analytics first-party cookies are read and/or written.

The webpage then sends an invisible gif request containing all the data to the secure Google Analytics reporting server, where the data is captured and processed.

Data is processed regularly throughout the day and you can see the results in your reports.
