How to track scroll depth in GA4?

ROI answers

Scroll depth tracking in GA4 measures how far down a user scrolls on a webpage, providing insights into content engagement and identifying potential drop-off points. As of early 2026, this is achieved using enhanced measurement and custom event configurations within the platform.

  • Enhanced Measurement: GA4 now features automatic scroll tracking, capturing 25%, 50%, 75%, and 100% scroll depths as standard events.
  • Custom Event Creation: For more granular tracking – say, at 30% or 60% – you can define custom scroll depth events using Google Tag Manager (GTM).
  • User Properties: Scroll depth data can be combined with user properties (like industry or location) to personalise insights and optimise content for specific Australian demographics.
  • Cross-Platform Consistency: GA4’s unified data model ensures scroll depth is tracked consistently across website and app interactions.

In 2026, Australian businesses must be mindful of data privacy regulations, including the ongoing refinements to the Privacy Act. GA4’s consent mode, when correctly implemented, helps ensure compliance by adjusting data collection based on user consent preferences, crucial for maintaining trust with your customers. Current systems include robust data anonymisation features to further protect user privacy.
