We open with a compact micro‑case: a paid campaign that burned thousands because a misformatted phone field stopped checkouts. In this tight, practical episode Gustavo (measurement) and Michelle (UX) walk listeners through a measurement‑led, low‑barrier playbook: how to recognize when a form ‘fails’ (plain English: when someone clicks submit and nothing happens or they abandon mid‑field), capture privacy‑safe signals to prove it, and implement no‑code fallbacks plus dev‑light patches that ship fast. Early minutes prioritize fixes non‑technical teams can apply—HTML autocomplete, input types, smart defaults, and accessible error copy—then show how to validate with short analytics checks and three quick user calls. We surface a short accessibility assurance (screen‑reader and keyboard sanity checks) and end with an explicit challenge: download the 72‑hour Form Forensics checklist from the show notes and close one leak this week.
