About this skill

/iblai-marketing-form-cro

Maximize form completion rates while capturing only the data that matters.

Step 0: Context Check

Read .agents/product-marketing-context.md (or .claude/product-marketing-context.md on older setups) first. Only ask for what isn't there.

Identify before optimizing:

  1. Form type
    • Lead capture (gated content, newsletter)
    • Contact
    • Demo/sales request
    • Application
    • Survey/feedback
    • Checkout
    • Quote request

  1. Current state

    • Field count
    • Current completion rate
    • Mobile vs. desktop split
    • Where users abandon

  2. Business context

    • What happens with submissions
    • Which fields actually get used in follow-up
    • Compliance / legal requirements

Core Principles

1. Every Field Has a Cost

Each field reduces completion. Rule of thumb:

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

Per field, ask:

  • Absolutely necessary before we can help them?
  • Can we get this info another way?
  • Can we ask for it later?

2. Value Must Exceed Effort

  • Clear value prop above the 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

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

Name

  • Single "Name" vs. First/Last — test it
  • Single field reduces friction
  • Split 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
  • Radio buttons if < 5 options
  • "Other" option with text field

Checkboxes (Multi-Select)

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

Form Layout

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 when many fields

Labels and Placeholders

  • Labels: keep visible (not just placeholder) — placeholders disappear when typing, leaving users unsure what they're filling
  • 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

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

Best Practices

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

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 leave a 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 the form on error

Submit 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"

Placement

  • Immediately after the 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 prop for what they get
  • Ask 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
  • Skip logic for relevance
  • Consider an incentive for completion

Mobile

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