How to read these answers
Each answer opens with the short version in bold. Most then set one store's anonymised GA4 export next to the usual answer. That export describes one store, not a benchmark, and holds shares of revenue only.
Every other figure comes from a platform's own help page, linked inside the answer, or is a worked example labelled as one. Each answer ends with three checks you can run this week, with what a pass and a fail look like.
Check the homework. Your GA4 Attribution paths export already holds the evidence. Causality Engine reads that one file and shows what each channel caused next to what last-click gave it, in 1 to 2 minutes, for €99 once (excluding VAT), refundable within 30 days. Check the homework
