You're setting up your web data stream so that your website is feeding your Google Analytics property with data. While setting up this web data stream, what happens when you leave the enhanced measurement setting enabled?

Enhanced measurement in Google Analytics 4 (GA4) automatically collects a variety of common user interactions as events without requiring any additional code changes to your website. These include page views, scrolls, outbound clicks, site search, video engagement, and file downloads. This feature simplifies data collection and provides immediate insights into user behavior. The other options are incorrect because: Conversion reporting for web data streams uses attribution models, not machine learning to distribute credit across channels. Enhanced measurement is specific to web data streams and does not combine data from mobile apps; that requires separate mobile app data streams. Associating events with signed-in users for cross-device reporting is achieved through User-ID implementation, not directly by enhanced measurement.
