Best Practices
Follow these proven practices to create forms that convert better and provide a great user experience. Small improvements can lead to significant gains.
Form Design
Keep forms short and focused
Ask for unnecessary information
Every extra field can reduce completion rates by 5-10%
Use clear, descriptive labels
Use jargon or ambiguous terms
Labels should tell users exactly what to enter
Group related fields together
Scatter related information throughout the form
Use sections to organize complex forms
User Experience
Show progress indicators on long forms
Leave users guessing how much is left
Flow Forms automatically show progress
Use inline validation
Wait until submission to show errors
Help users fix mistakes as they type
Make the submit button stand out
Hide or minimize the call to action
Use contrasting colors for your submit button
Mobile Optimization
Test on mobile devices
Assume desktop designs work on mobile
Over 50% of form submissions come from mobile
Use appropriate input types
Use text inputs for everything
Email fields show @ keyboard, number fields show numpad
Make tap targets large enough
Crowd elements too close together
Minimum 44x44px for touch targets
Conversion Optimization
Start with easy questions
Ask sensitive info upfront
Build trust before asking for email or phone
Use social proof when appropriate
Leave users wondering if they can trust you
Mention how many people have signed up
Customize the thank you message
Use generic confirmation text
Set expectations for what happens next
