Conversion Event Tracking
Also known as key events · goal tracking · conversion tracking
Marking the high-value actions on your site—form submits, purchases, signups—as GA4 key events so they can be measured and optimized.
What it is
Conversion event tracking is the practice of defining the actions that matter (lead form submit, purchase, signup, demo request) as GA4 events and marking them as key events, formerly called conversions. These events can be created from interactions, configured in GA4, or sent through Google Tag Manager.
Why it matters
Pageviews alone do not tell you whether traffic, including visitors arriving from AI assistants and answer engines, actually produces business outcomes. Conversion events tie visibility work to revenue and let you compare which channels and content drive real actions.
How to verify
Open GA4 DebugView and perform the action (submit the form, complete a test purchase) to confirm the event fires with the expected name and parameters. Then check Admin > Events and Key events to confirm the event is marked as a key event.
How to fix
Define the events for each critical action, fire them via GTM or gtag, and mark them as key events in GA4 Admin. Validate end-to-end in DebugView, then watch the Key events report to confirm data accrues correctly.
