## What it does

This skill provides a structured framework for reviewing registration funnels. It weighs step counts against completion benchmarks, showing 65–80% completion for single-page forms alongside a 10–20% user drop per extra step. It also models conversion losses from additional fields and details typical lifts from Google, Apple, or GitHub logins.

The skill details operational checklists: real-time inline error handling, retaining form data upon errors, and mobile touch targets of at least 44px. It also supplies industry conversion baselines for SaaS, FinTech, EdTech, and DevTools, plus 14 step-by-step A/B test hypotheses.

It functions well as a UI design review guide. Because the suggestions draw on industry baselines, your team will still need to confirm these friction points against live funnel data.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add OpenClaudia/openclaudia-skills --skill signup-flow-cro -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/signup-flow-cro/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/signup-flow-cro/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add OpenClaudia/openclaudia-skills --skill signup-flow-cro -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/signup-flow-cro/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add OpenClaudia/openclaudia-skills --skill signup-flow-cro -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/signup-flow-cro/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install OpenClaudia/openclaudia-skills signup-flow-cro
```

2. **Manually: put the files in place**
- File: `.github/skills/signup-flow-cro/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add OpenClaudia/openclaudia-skills --skill signup-flow-cro -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/OpenClaudia/openclaudia-skills --path skills/signup-flow-cro
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/signup-flow-cro/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add OpenClaudia/openclaudia-skills --skill signup-flow-cro -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/OpenClaudia/openclaudia-skills/tree/HEAD/skills/signup-flow-cro/SKILL.md

## When to use it
- audit multi-step signup funnels against drop-off benchmarks
- generate A/B test hypotheses for registration forms
- review mobile form layout against touch target standards
- evaluate conversion impact of social login providers

## Example prompts
- Audit our B2B SaaS registration flow and suggest A/B test hypotheses.
- Review this 4-step signup funnel and show where to reduce fields.
- Run a mobile CRO check on our signup page error handling.

# Signup Flow CRO

Audit and optimize signup conversion funnels to maximize registration completions.

---

## 1. Signup Flow Audit Framework

When auditing a signup flow, evaluate each of these dimensions:

### Number of Steps

| Steps | Benchmark Completion Rate | Notes |
|-------|--------------------------|-------|
| 1 (single page) | 65-80% | Best for simple products |
| 2 | 50-65% | Good balance of data collection and UX |
| 3 | 35-50% | Acceptable for complex products |
| 4+ | 20-35% | Only if justified by product complexity |

**Rule of thumb:** Every additional step loses 10-20% of users.

**Audit questions:**
- Can any steps be combined?
- Can any steps be deferred to post-signup?
- Is every step necessary for the user to start getting value?

### Form Fields

| Fields | Impact on Conversion |
|--------|---------------------|
| Email only | Highest conversion (baseline) |
| Email + password | -10-15% vs email only |
| Email + password + name | -15-25% vs email only |
| 5+ fields | -30-50% vs email only |

**Audit questions:**
- Which fields are truly required at signup? (vs. collected later)
- Can you use progressive profiling instead of upfront collection?
- Are field labels clear and unambiguous?
- Do fields use appropriate input types (email, tel, etc.)?
- Are there unnecessary fields (phone, company size, "how did you hear about us")?

### Social Login Options

| Provider | Typical Lift | Best For |
|----------|-------------|----------|
| Google | +15-25% | B2B, SaaS, productivity tools |
| Apple | +5-15% | iOS-first products, privacy-conscious users |
| GitHub | +10-20% | Developer tools |
| Microsoft | +5-15% | Enterprise, Office-adjacent tools |
| Facebook | +5-10% | B2C, social products (declining trust) |

**Audit questions:**
- Are social login buttons prominent or buried?
- Do social logins request minimal permissions?
- Is there a fallback if social auth fails?

### Progress Indicators

For multi-step flows, progress indicators reduce abandonment.

**Types:**
- Step counter ("Step 2 of 3")
- Progress bar (visual fill)
- Checklist (shows completed and upcoming steps)
- Breadcrumb ("Account > Profile > Preferences")

**Best practice:** Show remaining steps, not total steps. "Just 1 more step" is more motivating than "Step 3 of 4."

### Error Handling

**Audit checklist:**
- [ ] Inline validation (errors appear next to the field, not at top of form)
```
