Problem

You want to track when users click on specific buttons—such as “Sign Up,” “Add to Cart,” or “Download”—to measure engagement or conversion steps.

Solution

Button clicks are not tracked by default in GA4. To capture them, you’ll typically use Google Tag Manager (GTM) to detect the click and send a custom GA4 event. You can then mark that event as a conversion in GA4 if desired.

Notes

• Use meaningful and consistent event names for easier reporting
• Avoid over-tagging (track key actions, not every minor interaction)
• You can build audiences based on button click behavior (e.g., “users who clicked download”)
