Getting traffic but no sales? This ranks the real likely causes — offer, message-match, proof, price, friction or traffic quality — names the one thing to fix first, and gives you fast checks to confirm it. A diagnosis, never a guessed 'lift'.
Give the numbers and it computes your real rate and reasons from it. Never invents benchmarks or predicts a lift.
Every account gets one free run, then it's 1 credit each (free monthly credits cover normal use).
No — and it won't pretend to. It diagnoses the likely causes and what to check to confirm them; it never invents a benchmark or predicts a specific conversion-rate lift. Real gains only show up when you test the fix.
No, but they help. With your traffic and conversions it computes your actual rate and reasons from it. Without them it still ranks the likely causes from your description of the offer and funnel.
A checklist lists everything you could change. This reasons about your specific case, ranks the causes by how likely and how damaging they are, and names the one to fix first — so you don't waste weeks on the wrong thing.
