What this tool does

Custom GA4 events need correct naming and parameter structure — malformed events pollute reports or fail to fire.

This builder validates event names and outputs copy-ready gtag snippets entirely in your browser.

How to use it

  1. 1

    Choose a recommended event or enter a custom event name.

  2. 2

    Add category, label, and optional value parameters.

  3. 3

    Review validation warnings and copy the gtag snippet into your site.

Event naming best practices

Use lowercase snake_case: sign_up, not Sign Up or signUp. Stick to recommended events when they fit — Google pre-maps them in reports.

Keep parameter names consistent across events so you can build comparisons and explorations later.

Tips

  • Test events in GA4 DebugView before deploying to production.
  • Document custom events in a shared spec sheet for your team.
