## When to Build vs When Not To

**Build a free tool when:**
- Search volume exists for "[topic] calculator/generator/checker" (> 500/month)
- No excellent free alternative exists (or you can be 10x better)
- The tool naturally connects to your paid product
- You have engineering resources to build AND maintain it
- The tool produces shareable, bookmark-worthy output

**Do NOT build when:**
- A well-established free tool already exists and is sufficient
- The tool would be a thin wrapper with no unique value
- You cannot maintain it post-launch
- The tool requires data you do not have or cannot access
- Total addressable search volume is < 200/month

## Tool Type Selection

| Tool Type | What It Does | Build Complexity | Lead Capture Fit | SEO Value | Example |
|-----------|-------------|-----------------|-----------------|-----------|---------|
| Calculator | Takes inputs, outputs a number/range | Low-Medium | High (email the full report) | High | ROI calculator, LTV calculator, salary calculator |
| Generator | Creates text, ideas, or structured content | Low (template) to High (AI) | Medium (save/download results) | High | Headline generator, name generator, bio writer |
| Checker/Auditor | Analyzes a URL, text, or file and scores it | Medium-High | Very high (full report via email) | Very high | SEO audit, readability checker, accessibility checker |
| Grader | Scores something against a rubric | Medium | High (detailed scorecard) | High | Website grader, email subject line grader |
| Converter | Transforms input from one format to another | Low-Medium | Low (utility, quick use) | Medium | Unit converter, file converter, timezone converter |
| Template Library | Pre-built fillable documents | Very low | Medium (download gated) | High | Contract templates, brief templates, spreadsheet templates |
| Interactive Visualization | Shows data or concepts visually | High | Medium | Very high (link magnet) | Market maps, comparison charts, trend visualizers |

### Selection Decision Tree

```
What do you want to generate?
├── Leads (email capture) → Checker/Auditor or Calculator (report gating)
├── SEO traffic → Calculator or Checker (high search volume keywords)
├── Backlinks → Interactive Visualization or Template Library (link magnet)
├── Brand awareness → Generator (shareable output, social virality)
└── All of the above → Checker/Auditor (highest combined value)
```

## 6-Factor Evaluation Framework

Score each tool idea 1-5 on each factor. Maximum score: 30.

| Factor | What to Check | 1 (Weak) | 3 (Moderate) | 5 (Strong) |
|--------|--------------|----------|-------------|-----------|
| Search Volume | Monthly searches for "free [tool]" | < 100/mo | 500-2,000/mo | > 5,000/mo |
| Competition | Quality of existing free tools | Excellent tools exist | Decent tools, room to improve | No good free alternatives |
| Build Effort | Engineering time required | Months of work | 1-2 weeks | Days |
| Lead Capture Potential | Natural email gate opportunity | Forced gate kills UX | Reasonable gate | Natural fit (report, saved results) |
| SEO Value | Topical authority and backlink potential | Thin, one-page utility | Moderate content depth | Deep use case, link magnet |
| Viral Potential | Will users share results or embed? | Nobody would share | Some sharing potential | Results are inherently shareable |

### Scoring Thresholds

| Score | Decision |
|-------|----------|
| 25-30 | Build immediately -- strong across all factors |
| 20-24 | Strong candidate -- validate search volume before committing |
| 15-19 | Conditional -- only if resources are available and strategic fit is strong |
| < 15 | Do not build -- rethink the concept or find a different angle |

## Tool Design Principles

### Value Before Gate

**The cardinal rule:** Give the core value first. Gate the upgrade.

| Good | Bad |
|------|-----|
| Show the score immediately, offer to email the full report | "Enter your email to see your results" |
| Display the generated content, gate the save/export | Block all output behind email wall |
| Free basic analysis, premium detailed breakdown | Nothing visible without signup |

### Minimal Friction Input

- Maximum 3 inputs to get initial results
- No account required for core value
- Progressive disclosure: simple first, detailed on request
- Smart defaults where possible (auto-detect, pre-fill)

### Shareable Output

Design results so users want to share them:

| Mechanism | Implementation |
|-----------|---------------|
| Unique results URL | Each run gets a shareable permalink |
| Social share buttons | "Tweet your score" with pre-filled text |
| Downloadable report | PDF or CSV export |
| Embeddable badge/widget | "Scored 92/100 by [Your Tool]" badge |
| Visual score card | Social-media-ready image with result |

### Mobile-First Design

- All inputs work on touch screens
- Results render cleanly on mobile
- Share buttons trigger native share she
