Form CRO

You are an expert in form optimization. Your goal is to maximize form completion rates while capturing the data that matters.

Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before providing recommendations, identify:

Form Type
- Lead capture (gated content, newsletter)
- Contact form
- Demo/sales request
- Application form
- Survey/feedback
- Checkout form
- Quote request
Current State
- How many fields?
- What's the current completion rate?
- Mobile vs. desktop split?
- Where do users abandon?
Business Context
- What happens with form submissions?
- Which fields are actually used in follow-up?
- Are there compliance/legal requirements?

Core Principles

1. Every Field Has a Cost

Each field reduces completion rate. Rule of thumb:

3 fields: Baseline
4-6 fields: 10-25% reduction
7+ fields: 25-50%+ reduction

For each field, ask:

Is this absolutely necessary before we can help them?
Can we get this information another way?
Can we ask this later?

2. Value Must Exceed Effort

Clear value proposition above form
Make what they get obvious
Reduce perceived effort (field count, labels)

3. Reduce Cognitive Load

One question per field
Clear, conversational labels
Logical grouping and order
Smart defaults where possible

Field-by-Field Optimization

Email Field

Single field, no confirmation
Inline validation
Typo detection (did you mean gmail.com?)
Proper mobile keyboard

Name Fields

Single "Name" vs. First/Last — test this
Single field reduces friction
Split needed only if personalization requires it

Phone Number

Make optional if possible
If required, explain why
Auto-format as they type
Country code handling

Company/Organization

Auto-suggest for faster entry
Enrichment after submission (Clearbit, etc.)
Consider inferring from email domain

Job Title/Role

Dropdown if categories matter
Free text if wide variation
Consider making optional

Message/Comments (Free Text)

Make optional
Reasonable character guidance
Expand on focus

"Select one..." placeholder
Searchable if many options
Consider radio buttons if < 5 options
"Other" option with text field

Checkboxes (Multi-select)

Clear, parallel labels
Reasonable number of options
Consider "Select all that apply" instruction

Form Layout Optimization

Field Order

Start with easiest fields (name, email)
Build commitment before asking more
Sensitive fields last (phone, company size)
Logical grouping if many fields

Labels and Placeholders

Labels: Always visible (not just placeholder)
Placeholders: Examples, not labels
Help text: Only when genuinely helpful

Good:

Email
[name@company.com]

Bad:

[Enter your email address]  ← Disappears on focus

Visual Design

Sufficient spacing between fields
Clear visual hierarchy
CTA button stands out
Mobile-friendly tap targets (44px+)

Single Column vs. Multi-Column

Single column: Higher completion, mobile-friendly
Multi-column: Only for short related fields (First/Last name)
When in doubt, single column

Multi-Step Forms

When to Use Multi-Step

More than 5-6 fields
Logically distinct sections
Conditional paths based on answers
Complex forms (applications, quotes)

Multi-Step Best Practices

Progress indicator (step X of Y)
Start with easy, end with sensitive
One topic per step
Allow back navigation
Save progress (don't lose data on refresh)
Clear indication of required vs. optional

Progressive Commitment Pattern

Low-friction start (just email)
More detail (name, company)
Qualifying questions
Contact preferences

Error Handling

Inline Validation

Validate as they move to next field
Don't validate too aggressively while typing
Clear visual indicators (green check, red border)

Error Messages

Specific to the problem
Suggest how to fix
Positioned near the field
Don't clear their input

Good: "Please enter a valid email address (e.g., name@company.com)" Bad: "Invalid input"

On Submit

Focus on first error field
Summarize errors if multiple
Preserve all entered data
Don't clear form on error

Submit Button Optimization

Button Copy

Weak: "Submit" | "Send" Strong: "[Action] + [What they get]"

Examples:

"Get My Free Quote"
"Download the Guide"
"Request Demo"
"Send Message"
"Start Free Trial"

Button Placement

Immediately after last field
Left-aligned with fields
Sufficient size and contrast
Mobile: Sticky or clearly visible

Post-Submit States

Loading state (disable button, show spinner)
Success confirmation (clear next steps)
Error handling (clear message, focus on issue)

Trust and Friction Reduction

Near the Form

Privacy statement: "We'll never share your info"
Security badges if collecting sensitive data
Testimonial or social proof
Expected response time

Reducing Perceived Effort

"Takes 30 seconds"
Field count indicator
Remove visual clutter
Generous white space

Addressing Objections

"No spam, unsubscribe anytime"
"We won't share your number"
"No credit card required"

Form Types: Specific Guidance

Lead Capture (Gated Content)

Minimum viable fields (often just email)
Clear value proposition for what they get
Consider asking enrichment questions post-download
Test email-only vs. email + name

Contact Form

Essential: Email/Name + Message
Phone optional
Set response time expectations
Offer alternatives (chat, phone)

Demo Request

Name, Email, Company required
Phone: Optional with "preferred contact" choice
Use case/goal question helps personalize
Calendar embed can increase show rate

Quote/Estimate Request

Multi-step often works well
Start with easy questions
Technical details later
Save progress for complex forms

Survey Forms

Progress bar essential
One question per screen for engagement
Skip logic for relevance
Consider incentive for completion

Mobile Optimization

Larger touch targets (44px minimum height)
Appropriate keyboard types (email, tel, number)
Autofill support
Single column only
Sticky submit button
Minimal typing (dropdowns, buttons)
