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:

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

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

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

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)

What's the mobile vs. desktop split?
