# 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 `.agents/product-marketing-context.md` exists (or `.claude/product-marketing-context.md` in older setups), 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:

1. **Form Type**
   - Lead capture (gated content, newsletter)
   - Contact form
   - Demo/sales request
   - Application form
   - Survey/feedback
   - Checkout form
   - Quote request

2. **Current State**
   - How many fields?
   - What's the current completion rate?
   - Mobile vs. desktop split?
   - Where do users abandon?

3. **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

### Dropdown Selects
- "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
1. Start with easiest fields (name, email)
2. Build commitment before asking more
3. Sensitive fields last (phone, company size)
4. 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
[[email protected]]
```

**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
1. Low-friction start (just email)
2. More detail (name, company)
3. Qualifying questions
4. 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., [email protected])"
**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)

---

Frequently Asked Questions

What types of forms does this skill cover?

The skill handles lead capture forms, contact forms, demo request forms, application forms, survey forms, checkout forms, and quote request forms. It provides type-specific guidance — for example, recommending calendar embeds for demo requests and progressive profiling for lead capture. For signup and registration forms, see the signup-flow-cro skill instead.

How does it approach field optimization?

The skill treats every field as having a cost to completion rate. It provides benchmarks (3 fields as baseline, 7+ fields causing 25-50% reduction) and asks three questions for each field: is it absolutely necessary, can the information be gathered another way (like email domain enrichment), and can it be asked later? It also covers field-specific optimization for email, name, phone, company, and dropdown fields.

Does it cover multi-step forms?

Yes. The skill includes guidance on when to use multi-step forms (more than 5-6 fields, logically distinct sections, conditional paths), along with best practices like progress indicators, progressive commitment patterns (start with email, add detail gradually), saving progress, and allowing back navigation.

What about mobile form optimization?

The skill includes dedicated mobile optimization guidance: larger touch targets (44px minimum), appropriate keyboard types for each field, autofill support, single-column-only layout, sticky submit buttons, and minimizing typing through dropdowns and buttons.

Does it work in Claude.ai chat?

Yes, this skill is chat-compatible and works in any Claude interface since it doesn't require code execution or external APIs.
