Scroll Tracking with Google Tag Manager and Google Analytics 4 (2021)


A step-by-step tutorial on how to implement scroll tracking with Google Tag Manager and Google Analytics 4. There are two approaches that you can choose from and I’ll explain both.

The built-in scroll tracking in Google Analytics 4 is quite limited. By default, it tracks only the 90% mark. What if you also want to track other thresholds like 25%, 50%, 75%? You’ll have to use Google Tag Manager and modify the setup.

    I'm having an issue where the tags are firing correctly in gtm and in the ga4 debug mode, but when create a table in ga4 of page title, scroll depth and sessions, the scroll depth values all display zeros. Please can you help me with this? Thanks

    Great video. All is working correctly, except: "not set" is one of the percent_scrolled values being reported, and is by far the largest. How can this value be accounted for? Event is set up for 25, 50, 75, 90. Could "not set" be 0%?

    I like the GTM scroll trigger combined with the timer trigger of say 60 seconds to track engagement. Thanks
