What problem does it solve?
Your landing signup form asks for too much too soon, so visitors abandon before they ever experience the product.
Who is it for?
Indie SaaS or content products iterating on a simple email-or-password signup on a marketing landing page.
Skip if: Regulated KYC onboarding, complex B2B procurement forms, or flows where legal must collect many fields on day one.
When should I use this skill?
Use when auditing or redesigning a signup or registration flow to improve conversion on a landing or onboarding surface.
What do I get? / Deliverables
You get an optimized field list and UX patterns (validation, password, progress, messaging) that increase completed signups with clearer expectations after submit.
- Prioritized field keep/defer list
- Per-field UX recommendations
- Messaging for effort and post-signup expectations

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Validate because signup CRO proves demand and reduces friction before you invest in full product build. Landing covers acquisition surfaces where email capture and account creation directly affect whether visitors become users.
Where it fits
Strip deferrable company and phone fields from a waitlist form and add a 30-second expectation line.
Reorder the landing so visitors try a demo widget before the email capture step.
Fix password UX (toggle, paste allowed, upfront rules) to recover users dropping on the second step of onboarding.
How it compares
Focused signup UX and CRO heuristics—not full funnel analytics implementation or A/B test infrastructure.

READMESKILL.md - Signup Flow Cro
# signup-flow-cro reference ## Core Principles ### 1. Minimize Required Fields Every field reduces conversion. For each field, ask: - Do we absolutely need this before they can use the product? - Can we collect this later through 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/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 - Check for 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 strength meter instead of rigid rules - Consider passwordless options ### Name Field - Single "Full name" field vs. First/Last split (test this) - Only require if immediately used (personalization) - Consider making optional ### Social Auth Options - Place prominently (often higher conversion than email) - Show 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, keep to one question - Use 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 should feel 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: Use for examples, not labels - Labels: Always visible (not just placeholders) - Help text: Only when needed, placed close to 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 - Immedi
