Testing tells you which idea wins. Something still has to build it.

Often yes, and they do different jobs. Use Mimetic to find what is actually costing you orders and to get the changes prepared. Use Shoplift when the change is a genuine judgement call, a layout or an offer, and you have the traffic to settle it properly. We are not asking you to drop your testing tool.

When the finding is a functional failure. If Add to Cart does not respond in the Instagram in-app browser, that is a defect. Running a test to confirm that a working button beats a broken one spends traffic to learn nothing. Fix it, verify it is fixed, and save the testing budget for real questions.

That is one of the more useful things it does. The scan produces a prioritized list with estimated monthly impact and the assumptions behind each estimate, so your testing roadmap starts from evidence about your store rather than a backlog of ideas.

Only if your measurement is sound. The scan checks whether your pixels and analytics are firing correctly and counting once, which is worth doing before you trust any test readout. Duplicate or missing purchase events will quietly corrupt results in either direction.
