How to Configure Scroll Depth Tracking in Google Tag Manager

Author:

Scroll depth tracking is a valuable metric for understanding user engagement on your website. It allows you to see how far down a page users are scrolling, which can help you optimize content placement and design. Google Tag Manager (GTM) makes it easy to set up scroll depth tracking without needing to modify your website’s code directly. Here’s a step-by-step guide to configure scroll depth tracking in GTM:

 1. Set Up Google Tag Manager

If you haven’t already set up GTM on your website, follow these steps:

  1. Create a GTM Account:
    • Go to the Google Tag Manager website and sign in with your Google account.
    • Click on “Create Account,” and follow the instructions to set up your account and container.
  2. Install GTM on Your Website:
    • Once your container is created, you’ll receive a snippet of code.
    • Add this code to every page of your website, ideally within the <head> and <body> tags.

 2. Enable Built-in Variables

To track scroll depth, you need to enable certain built-in variables in GTM:

  1. Access Built-in Variables:
    • In your GTM workspace, navigate to “Variables” on the left-hand side.
    • Click on “Configure” in the “Built-In Variables” section.
  2. Enable Scroll Variables:
    • Check the boxes for the following variables: Scroll Depth Threshold, Scroll Depth Units, and Scroll Direction.

 3. Create a Scroll Depth Trigger

A trigger is an event that tells GTM when to fire a tag. For scroll depth tracking, you need to create a scroll depth trigger:

  1. Create a New Trigger:
    • Go to “Triggers” and click on “New”.
    • Name your trigger something like “Scroll Depth Trigger”.
  2. Configure Trigger Settings:
    • Choose “Scroll Depth” as the trigger type.
    • Configure the trigger to fire based on your requirements:
      • Vertical Scroll Depths: Enter the percentage thresholds at which you want the trigger to fire (e.g., 25%, 50%, 75%, 100%).
      • Horizontal Scroll Depths: If you want to track horizontal scrolling, you can specify those thresholds as well.
      • Scroll Direction: Choose “Vertical” (most common for web pages).

 4. Create a Tag to Track Scroll Depth

Tags are snippets of code that execute when a trigger is activated. To track scroll depth, you can use a Google Analytics event tag:

  1. Create a New Tag:
    • Navigate to “Tags” and click on “New”.
    • Name your tag something like “GA – Scroll Depth Tracking”.
  2. Configure Tag Settings:
    • Choose “Google Analytics: Universal Analytics” as the tag type.
    • Set the “Track Type” to “Event”.
    • Configure the event tracking parameters:
      • Category: Scroll Depth
      • Action: Scroll
      • Label: {{Scroll Depth Threshold}}%
  3. Link the Tag to Your Google Analytics Account:
    • Enter your Google Analytics Tracking ID in the “Google Analytics Settings” field. If you have already set up a variable for your tracking ID, you can select it here.
  4. Attach the Trigger:
    • Click on “Triggering” and select the “Scroll Depth Trigger” you created earlier.
  5. Save Your Tag:
    • Save your tag configuration.

 5. Test Your Setup

Before publishing your changes, it’s important to test to ensure everything is working correctly:

  1. Enter Preview Mode:
    • In GTM, click on “Preview” to enter preview mode. This allows you to test your tags in a debug environment.
  2. Navigate to Your Website:
    • Open your website in a new tab or window. You should see the GTM debug console at the bottom of the screen.
  3. Test Scroll Depth:
    • Scroll down the page and observe the debug console. Ensure that the “GA – Scroll Depth Tracking” tag is firing correctly at the specified thresholds (e.g., 25%, 50%, 75%, 100%).
  4. Verify in Google Analytics:
    • Go to your Google Analytics account and navigate to “Real-Time” > “Events”. Check if the scroll depth events are being recorded correctly.

 6. Publish Your Container

Once you’ve verified that your scroll depth tracking is working correctly, you can publish your GTM container to make the changes live:

  1. Submit and Publish:
    • In GTM, click on “Submit” and then follow the prompts to publish your container.

 7. Analyze the Data

  1. View Events in Google Analytics:
    • Go to “Behavior” > “Events” > “Overview” in Google Analytics to see the scroll depth events.
    • Analyze the data to understand user engagement and how far down the page visitors are scrolling.
  2. Make Data-Driven Decisions:
    • Use the insights from the scroll depth data to optimize content placement and page design. For example, if you notice that users are not scrolling past a certain point, consider moving important content higher up on the page.

Configuring scroll depth tracking in Google Tag Manager is a straightforward process that provides valuable insights into user engagement on your website. By following these steps, you can set up effective tracking, gain a better understanding of how users interact with your content, and make data-driven decisions to enhance the user experience. Regular monitoring and analysis of the scroll depth data will help you continuously optimize your website for better performance and user engagement.
