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:
Flow type
- Free trial signup
- Freemium account creation
- Paid account creation
- Waitlist / early access signup
- B2B vs. B2C
Current state
- Steps/screens
- Required fields
- Current completion rate
- Where users drop off
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:
- Email only (lowest barrier)
- Password + name
- 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:
- Quick wins (same-day fixes)
- High-impact changes (week-level effort)
- 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
- Email + Password (or Google auth)
- Name + Company (optional: role)
- → Onboarding flow
B2C App
- Google/Apple auth OR email
- → Product experience
- Profile completion later
Waitlist / Early Access
- Email only
- Optional: role/use case question
- → Waitlist confirmation
E-commerce Account
- Guest checkout as default
- Account creation optional post-purchase
- OR social auth with single click
