What checkout abandonment detection should prove
Checkout abandonment is not always a marketing issue. If add-to-cart works but checkout, payment or confirmation stops, the visible symptom can be fewer orders rather than a fully offline site.
Detection should separate a normal buyer drop-off from a technical break: missing payment methods, Store API failures, blocked validation, redirect loops, cache/session loss or a confirmation step that never appears.
Signals to monitor
- Cart still fills but fewer sessions reach checkout or confirmation.
- Checkout form renders while payment methods, shipping rates or validation are missing.
- The place-order action fails, loops or never reaches an order received state.
- Traffic and uptime look normal while WooCommerce no-orders periods appear.
- A plugin update, cache rule or payment script changes the last green checkout journey.
Useful evidence for teams
Useful evidence names the step where the drop appears, the expected signal, the observed signal, the timestamp, the priority and a plain-language revenue exposure context. It does not need customer names, emails, payment data or exact cart contents.
