Choose indicators that represent actual steps in the customer journey.
01Separate the steps
For a diagnostic tool, distinguish a started scan, a completed scan, a failure and an accepted report request. Clicking Send on a form does not prove that the server accepted the request.
02Verify tracking end to end
Check website behaviour and then event reception in your analytics tool. An event in the source code does not prove its arrival in GA4. Check for duplicates and avoid sending email addresses in analytics events.
03Connect numbers to contact quality
A report request is not necessarily a quote request. Compare periods, channels and pages, then add commercial feedback: actual need, service area and next steps. With small volumes, review counts as well as percentages.
