Reduce signup friction, lift completion rates, and set users up for successful activation.

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.

Pin down before recommending:

1. Flow type

- Free trial signup - Freemium account creation - Paid account creation - Waitlist / early access signup - B2B vs. B2C

1. Current state

- Steps/screens - Required fields - Current completion rate - Where users drop off

1. Business constraints

- Data genuinely needed at signup - Compliance requirements - What happens immediately after signup

Core Principles

1. Minimize Required Fields

Every field cuts conversion. Per field, ask:

• Do we absolutely need this before they can use the product?
• Can we collect this later via progressive profiling?
• Can we infer this from other data?

Typical field priority:

• Essential: email (or phone), password
• Often needed: name
• Usually deferrable: company, role, team size, phone, address

2. Show Value Before Asking for Commitment

• What can you show or give before requiring signup?
• Can they experience the product before creating an account?
• Reverse the order: value first, signup second

3. Reduce Perceived Effort

• Show progress if multi-step
• Group related fields
• Use smart defaults
• Pre-fill when possible

4. Remove Uncertainty

• Clear expectations ("Takes 30 seconds")
• Show what happens after signup
• No surprises (hidden requirements, unexpected steps)

Field-by-Field Optimization

Email Field

• Single field (no email confirmation field)
• Inline validation for format
• Catch common typos (gmial.com → gmail.com)
• Clear error messages

Password Field

• Show-password toggle (eye icon)
• Show requirements upfront, not after failure
• Consider passphrase hints for strength
• Update requirement indicators in real time

Better password UX:

• Allow paste — don't disable
• Show a strength meter instead of rigid rules
• Consider passwordless options

Name Field

• Single "Full name" field vs. First/Last split (test it)
• Only require if immediately used (personalization)
• Consider making optional

Social Auth Options

• Place prominently — often higher conversion than email
• Show the most relevant options for your audience

- B2C: Google, Apple, Facebook - B2B: Google, Microsoft, SSO

• Clear visual separation from email signup
• Consider "Sign up with Google" as primary

Phone Number

• Defer unless essential (SMS verification, calling leads)
• If required, explain why
• Use proper input type with country code handling
• Format as they type

Company / Organization

• Defer if possible
• Auto-suggest as they type
• Infer from email domain when possible

Use Case / Role Questions

• Defer to onboarding if possible
• If needed at signup, one question only
• Progressive disclosure — don't show all options at once

Single-Step vs. Multi-Step

Single-Step Works When:

• 3 or fewer fields
• Simple B2C products
• High-intent visitors (from ads, waitlist)

Multi-Step Works When:

• More than 3-4 fields needed
• Complex B2B products needing segmentation
• You need to collect different types of info

Multi-Step Best Practices

• Show progress indicator
• Lead with easy questions (name, email)
• Put harder questions later (after psychological commitment)
• Each step completable in seconds
• Allow back navigation
• Save progress (don't lose data on refresh)

Progressive commitment pattern:

1. Email only (lowest barrier)
2. Password + name
3. Customization questions (optional)

Trust and Friction Reduction

At the Form Level

• "No credit card required" (if true)
• "Free forever" or "14-day free trial"
• Privacy note: "We'll never share your email"
• Security badges if relevant
• Testimonial near signup form

Error Handling

• Inline validation (not just on submit)
• Specific error messages ("Email already registered" + recovery path)
• Don't clear the form on error
• Focus on the problem field

Microcopy

• Placeholder text: examples, not labels
• Labels: keep visible (not just placeholders) — placeholders disappear when typing, leaving users unsure what they're filling in
• Help text: only when needed, placed close to the field

Mobile Signup Optimization

• Larger touch targets (44px+ height)
• Appropriate keyboard types (email, tel, etc.)
• Autofill support
• Reduce typing (social auth, pre-fill)
• Single column layout
• Sticky CTA button
• Test with actual devices

Post-Submit Experience

Success State

• Clear confirmation
• Immediate next step
• If email verification required:

- Explain what to do - Easy resend option - Check spam reminder - Option to change email if wrong

Verification Flows

• Delay verification until necessary
• Magic link as alternative to password
• Let users explore while awaiting verification
• Clear re-engagement if verification stalls

Measurement

Key Metrics

• Form start rate (landed → started filling)
• Form completion rate (started → submitted)
• Field-level drop-off (which fields lose people)
• Time to complete
• Error rate by field
• Mobile vs. desktop completion

What to Track

• Each field interaction (focus, blur, error)
• Step progression in multi-step
• Social auth vs. email signup ratio
• Time between steps

Output Format

Audit Findings

Per issue:

• Issue: what's wrong
• Impact: why it matters (estimated impact if possible)
• Fix: specific recommendation
• Priority: High/Medium/Low

Recommended Changes

Organized by:

1. Quick wins (same-day fixes)
2. High-impact changes (week-level effort)
3. Test hypotheses (A/B tests)

Form Redesign (if requested)

• Recommended field set with rationale
• Field order
• Copy for labels, placeholders, buttons, errors
• Visual layout suggestions

Common Signup Flow Patterns

B2B SaaS Trial

1. Email + Password (or Google auth)
2. Name + Company (optional: role)
3. → Onboarding flow

B2C App

1. Google/Apple auth OR email
2. → Product experience
3. Profile completion later

Waitlist / Early Access

1. Email only
2. Optional: role/use case question
3. → Waitlist confirmation

E-commerce Account

1. Guest checkout as default
2. Account creation optional post-purchase
3. OR social auth with single click
