Removing a form field lifts completion a median ~4.7% — but auto-removing the wrong one can cut revenue per lead.
The mistake: treating all fields as equal friction. Dropping "company size" raises completion but degrades lead quality downstream.
— The real metric is qualified-conversions, not form submits.
— Fix: measure to the money event, not the form. Test field removal against downstream value, and make low-value fields optional before deleting.
Read the number, not the story. [field −1 ≈ +4.7% submits · n≈mixed]
