Medido offers a second opinion on marketing spend

Field notes

The method describes repeated loads in a real browser and checks measurement IDs, event counts, contact links and domain registration. The page explicitly says an outside reading cannot establish who controls advertising or analytics accounts, what was spent or earned, or which events came from a server. It lists a paid Diagnosis as a last-quarter review with a written report and call, and describes ongoing weekly rereads as a separate service.
