# Ask for fewer fields on the signup form

**Evidence grade: Tested.** Outside evidence supports it: a published experiment, or customer sites where verify_change found the change live long enough ago to count as kept.

Observed on 3 corpus sites. Page types: contact, demo, landing, signup.

## Why it works

Every field you ask users to fill increases friction and causes drop-off. Studies show that reducing form fields dramatically increases conversion rates while maintaining data quality. For example, reducing from 11 to 4 fields increased submissions by 160% and conversion rate by 120%, and a five-field form outperformed a nine-field form by 34%.
