The Google Analytics tracking code can be placed in the Master Page or in individual ASP.NET web pages to track the activities in an ASP.NET web application.
Here are two common ways to add the Google Analytics code:
Remember to replace the placeholder 'UA-XXXXXXXXX-X' in the Google Analytics tracking code with your own Google Analytics tracking ID. This ID can be obtained from your Google Analytics account.
It is recommended to place the tracking code in the Master Page if you want the tracking to be applied to all pages in the web application. Otherwise, you can place the code in specific pages where you want to track the analytics.
