To use Analytics to collect website data, what must be added to the website page HTML?

To collect website data with Google Analytics, you must embed the Google Analytics tracking code into the HTML of every page you want to track. This JavaScript code snippet sends data about user interactions and page views to your Analytics property. Without this code, Analytics has no mechanism to gather information from your website. Google campaign parameters are used to track specific marketing campaigns, not for general data collection. Google Analytics terms and conditions are a legal agreement, not a technical requirement for data collection. A permissions button might be part of a consent management platform, but it's not the fundamental element for data collection itself.
