GA4 and GTM Event Planning for Leads and Ecommerce
A tracking plan defines the action, trigger and permitted parameters for each event. Successful lead submissions and purchases should be distinguished from intermediate clicks and form attempts.
What to do first
List the business questions and map each to a clearly defined event.
Implementation and review
- Trigger success events only after the application confirms the outcome, using a transaction or submission ID where appropriate.
- Test valid, invalid and repeated interactions in preview and DebugView before publishing.
What to watch for
Do not send email addresses or phone numbers as ordinary GA4 event parameters. A button click is not proof of submission.
A practical example to work through
For a lead form, test an empty submit, an invalid value, a valid submission, a repeat click and a reload of the confirmation view. The business success event should match the application's confirmed outcome in each case. Write down the expected behavior before the test. This turns event QA into something another team member can repeat after a site update.
