Event Reference (v1) / Primitive Events

Scroll scroll

Measures when % threshold of a web page is visible within a viewport.

This event is somewhat misleading if you utilize Google Tag Manager's scroll trigger. GTM's scroll trigger doesn't actually measure a "scroll" action - it measures when the bottom of the viewport (browser window) reaches a certain % threshold of the overall pixel height of a page. This means that users with large monitors will meet scroll % thresholds without an interaction when page content is shorter. This also means that scroll % events mean vastly different things depending on the size of the device screen (or more accurately browser window) being used.

GA4 implements this event as part of its "Enhanced Measurement" feature. It is recommended to use Google Tag Manager (GTM) to manage event flow and data collection. As such, we recommend disabling this event inside your GA4 Enhanced Measurement settings if you are using GTM.
