Covers idea evaluation with a 6-factor scoring system, tool design patterns, lead capture architecture, SEO landing page strategy, launch playbook, and ROI measurement. Applicable to calculators, generators, checkers, graders, converters, templates, and interactive visualizations.\n\n---\n\n## Table of Contents\n\n- [When to Build vs When Not To](#when-to-build-vs-when-not-to)\n- [Tool Type Selection](#tool-type-selection)\n- [6-Factor Evaluation Framework](#6-factor-evaluation-framework)\n- [Tool Design Principles](#tool-design-principles)\n- [Lead Capture Architecture](#lead-capture-architecture)\n- [SEO Landing Page Strategy](#seo-landing-page-strategy)\n- [Launch Playbook](#launch-playbook)\n- [Distribution Channels](#distribution-channels)\n- [Measurement Framework](#measurement-framework)\n- [Maintenance and Iteration](#maintenance-and-iteration)\n- [Output Artifacts](#output-artifacts)\n- [Related Skills](#related-skills)\n\n---\n\n## When to Build vs When Not To\n\n**Build a free tool when:**\n- Search volume exists for \"[topic] calculator/generator/checker\" (> 500/month)\n- No excellent free alternative exists (or you can be 10x better)\n- The tool naturally connects to your paid product\n- You have engineering resources to build AND maintain it\n- The tool produces shareable, bookmark-worthy output\n\n**Do NOT build when:**\n- A well-established free tool already exists and is sufficient\n- The tool would be a thin wrapper with no unique value\n- You cannot maintain it post-launch\n- The tool requires data you do not have or cannot access\n- Total addressable search volume is < 200/month\n\n---\n\n## Clarify First\n\nBefore designing the free tool, confirm these inputs. If any is unknown or vague, ASK — do not assume:\n\n- [ ] **Tool concept + type** — calculator, generator, checker, grader, converter, template, or visualization (drives build complexity and lead-capture fit)\n- [ ] **Target keyword + search volume** — the \"free [tool]\" search demand (a core factor in the 6-factor go/no-go score)\n- [ ] **Primary goal** — leads, SEO traffic, backlinks, or brand (selects the tool type and gate strategy)\n- [ ] **Connection to your paid product** — without it, leads won't convert (determines whether to build at all)\n\nStop rule: ask only the 2-3 that most change the output. If the user says \"just draft it,\" proceed and list your assumptions at the top of the plan.\n\n## Tool Type Selection\n\n| Tool Type | What It Does | Build Complexity | Lead Capture Fit | SEO Value | Example |\n|-----------|-------------|-----------------|-----------------|-----------|---------|\n| Calculator | Takes inputs, outputs a number/range | Low-Medium | High (email the full report) | High | ROI calculator, LTV calculator, salary calculator |\n| Generator | Creates text, ideas, or structured content | Low (template) to High (AI) | Medium (save/download results) | High | Headline generator, name generator, bio writer |\n| 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 |\n| Grader | Scores something against a rubric | Medium | High (detailed scorecard) | High | Website grader, email subject line grader |\n| Converter | Transforms input from one format to another | Low-Medium | Low (utility, quick use) | Medium | Unit converter, file converter, timezone converter |\n| Template Library | Pre-built fillable documents | Very low | Medium (download gated) | High | Contract templates, brief templates, spreadsheet templates |\n| Interactive Visualization | Shows data or concepts visually | High | Medium | Very high (link magnet) | Market maps, comparison charts, trend visualizers |\n\n### Selection Decision Tree\n\n```\nWhat do you want to generate?\n├── Leads (email capture) → Checker/Auditor or Calculator (report gating)\n├── SEO traffic → Calculator or Checker (high search volume keywords)\n├── Backlinks → Interactive Visualization or Template Library (link magnet)\n├── Brand awareness → Generator (shareable output, social virality)\n└── All of the above → Checker/Auditor (highest combined value)\n```\n\n---\n\n## 6-Factor Evaluation Framework\n\nScore each tool idea 1-5 on each factor. Maximum score: 30.\n\n| Factor | What to Check | 1 (Weak) | 3 (Moderate) | 5 (Strong) |\n|--------|--------------|----------|-------------|-----------|\n| Search Volume | Monthly searches for \"free [tool]\" | < 100/mo | 500-2,000/mo | > 5,000/mo |\n| Competition | Quality of existing free tools | Excellent tools exist | Decent tools, room to improve | No good free alternatives |\n| Build Effort | Engineering time required | Months of work | 1-2 weeks | Days |\n| Lead Capture Potential | Natural email gate opportunity | Forced gate kills UX | Reasonable gate | Natural fit (report, saved results) |\n| SEO Value | Topical authority and backlink potential | Thin, one-page utility | Moderate content depth | Deep use case, link magnet |\n| Viral Potential | Will users share results or embed? | Nobody would share | Some sharing potential | Results are inherently shareable |\n\n### Scoring Thresholds\n\n| Score | Decision |\n|-------|----------|\n| 25-30 | Build immediately -- strong across all factors |\n| 20-24 | Strong candidate -- validate search volume before committing |\n| 15-19 | Conditional -- only if resources are available and strategic fit is strong |\n| < 15 | Do not build -- rethink the concept or find a different angle |\n\n---\n\n## Tool Design Principles\n\n### Value Before Gate\n\n**The cardinal rule:** Give the core value first. Gate the upgrade.\n\n| Good | Bad |\n|------|-----|\n| Show the score immediately, offer to email the full report | \"Enter your email to see your results\" |\n| Display the generated content, gate the save/export | Block all output behind email wall |\n| Free basic analysis, premium detailed breakdown | Nothing visible without signup |\n\n### Minimal Friction Input\n\n- Maximum 3 inputs to get initial results\n- No account required for core value\n- Progressive disclosure: simple first, detailed on request\n- Smart defaults where possible (auto-detect, pre-fill)\n\n### Shareable Output\n\nDesign results so users want to share them:\n\n| Mechanism | Implementation |\n|-----------|---------------|\n| Unique results URL | Each run gets a shareable permalink |\n| Social share buttons | \"Tweet your score\" with pre-filled text |\n| Downloadable report | PDF or CSV export |\n| Embeddable badge/widget | \"Scored 92/100 by [Your Tool]\" badge |\n| Visual score card | Social-media-ready image with result |\n\n### Mobile-First Design\n\n- All inputs work on touch screens\n- Results render cleanly on mobile\n- Share buttons trigger native share sheet\n- No hover-dependent UI elements\n\n---\n\n## Lead Capture Architecture\n\n### When to Gate\n\n| Gate Decision | Criteria |\n|--------------|---------|\n| Gate with email | Results are complex (report format), ongoing value (re-run monthly), personalized output |\n| Do NOT gate | Core result is a single number, competition offers the same ungated, primary goal is SEO/backlinks |\n\n### Progressive Capture\n\nDo not ask for everything at once. Build the profile over multiple interactions.\n\n| Interaction | What to Capture | How |\n|------------|----------------|-----|\n| First use | Email (to save or email results) | Inline form after results display |\n| Return use | Name + Role | Contextual prompt, not a blocking form |\n| Repeated use | Company + Team size | If they request team features or saved history |\n\n### Capture Form Design\n\n- Email-only first gate (single field + submit button)\n- Position the form AFTER results are shown (not before)\n- Explain the value: \"Email me a detailed breakdown\" not \"Sign up\"\n- Privacy text: \"We'll send your report. No spam.\"\n- Never require account creation for the free tool\n\n---\n\n## SEO Landing Page Strategy\n\n### Page Structure\n\n```\nH1: Free [Tool Name] -- [What It Does in One Phrase]\nSubhead: [Who it is for] + [what problem it solves]\n\n[THE TOOL -- above the fold, interactive]\n\nH2: How [Tool Name] Works\n  (3-4 steps with screenshots)\n\nH2: Why [Audience] Use [Tool Name]\n  (Benefits, use cases, 3-5 paragraphs)\n\nH2: [Related Question 1] (FAQ-style, keyword-targeted)\nH2: [Related Question 2]\nH2: [Related Question 3]\n\nH2: Frequently Asked Questions\n  (5-7 FAQs with FAQPage schema)\n```\n\n### SEO Requirements\n\n- Target keyword in: H1, URL slug, meta title, first 100 words, 2+ subheadings\n- Meta title: \"Free [Tool Name]: [Action Verb] Your [Outcome] | [Brand]\"\n- Meta description: Include the keyword + what the tool does + \"Free, no signup required\"\n- URL: `/tools/[tool-name]` or `/free-[tool-name]`\n\n### Schema Markup\n\nAdd `SoftwareApplication` schema:\n\n```json\n{\n  \"@context\": \"https://schema.org\",\n  \"@type\": \"SoftwareApplication\",\n  \"name\": \"Free [Tool Name]\",\n  \"applicationCategory\": \"BusinessApplication\",\n  \"offers\": {\n    \"@type\": \"Offer\",\n    \"price\": \"0\",\n    \"priceCurrency\": \"USD\"\n  },\n  \"description\": \"[What the tool does]\",\n  \"operatingSystem\": \"Web\"\n}\n```\n\nAlso add FAQPage schema for the FAQ section.\n\n---\n\n## Launch Playbook\n\n### Pre-Launch (1-2 Weeks Before)\n\n- [ ] SEO landing page published and indexed\n- [ ] Schema markup validated\n- [ ] Outreach target list built (who links to similar tools?)\n- [ ] Product Hunt draft prepared (if applicable)\n- [ ] Social media teaser content created\n- [ ] Email announcement drafted for existing audience\n\n### Launch Week\n\n| Day | Channel | Action |\n|-----|---------|--------|\n| Day 1 | Email list | Announcement to existing subscribers |\n| Day 1 | Social media | Launch post on Twitter/X, LinkedIn |\n| Day 1 | Product Hunt | Submit (if applicable, aim for Tuesday-Thursday) |\n| Day 2 | Community | Share in relevant Slack groups, Discord, Reddit |\n| Day 3 | Outreach | Email bloggers, newsletter editors who cover tools |\n| Day 5 | Content | Publish blog post about the tool with use cases |\n| Day 7 | Social media | Results round-up, engagement post |\n\n### Post-Launch (Weeks 2-8)\n\n- [ ] Monitor search rankings for target keywords\n- [ ] Track backlinks with GSC or Ahrefs\n- [ ] Reach out to \"best [category] tools\" listicle authors\n- [ ] Submit to tool directories (Free Tools, AlternativeTo, etc.)\n- [ ] Iterate based on usage data (most-used features, drop-off points)\n\n---\n\n## Distribution Channels\n\n### Organic Channels\n\n| Channel | Approach | Expected Impact |\n|---------|----------|----------------|\n| SEO | Target \"[type] calculator/checker\" keywords | Long-term, compounding traffic |\n| Product Hunt | Launch listing | Spike traffic + backlinks |\n| Hacker News | \"Show HN\" post if technically interesting | Spike traffic + developer backlinks |\n| Reddit | Share in relevant subreddits (genuinely helpful, not spammy) | Moderate traffic + community feedback |\n| Twitter/X | Launch thread with tool demo | Engagement + social proof |\n| LinkedIn | Professional use case post | B2B lead generation |\n| Industry newsletters | Pitch to curators | Targeted audience + backlinks |\n\n### Link Acquisition\n\n| Source | Approach |\n|--------|---------|\n| \"Best [category] tools\" listicles | Find existing lists, pitch for inclusion |\n| Resource pages | Find industry resource compilations, suggest your tool |\n| Blog posts mentioning the problem your tool solves | Reach out with \"we built a free tool for this\" |\n| Comparison sites | Submit to tool comparison platforms |\n| Educational content | Pitch to courses, tutorials, guides that cover related topics |\n\n---\n\n## Measurement Framework\n\n### Key Metrics\n\n| Metric | What It Tells You | Target (90 days) |\n|--------|------------------|-----------------|\n| Tool usage (sessions) | Is anyone using it?

Not for tool-based content assets.\n- **schema-markup** -- Use for implementing SoftwareApplication and FAQPage schema on the tool landing page.\n- **form-cro** -- Use for optimizing the lead capture form within the tool.\n- **page-cro** -- Use for optimizing the landing page conversion rate.\n- **content-creator** -- Use for writing the blog post and social content supporting the tool launch.\n\n---\n\n## Tool Reference\n\n### 1. tool_idea_scorer.py\n\n**Purpose:** Score free tool ideas against the 6-factor evaluation framework and rank candidates.\n\n```bash\npython scripts/tool_idea_scorer.py tool_ideas.json\npython scripts/tool_idea_scorer.py tool_ideas.json --json\n```\n\n| Flag | Required | Description |\n|------|----------|-------------|\n| `tool_ideas.json` | Yes | JSON file with tool idea names and 6-factor scores |\n| `--json` | No | Output results as JSON |\n\n### 2. tool_roi_calculator.py\n\n**Purpose:** Calculate the ROI and break-even timeline for a free tool based on traffic, conversion, and cost assumptions.\n\n```bash\npython scripts/tool_roi_calculator.py --build-cost 5000 --monthly-traffic 2000 --conversion-rate 8 --lead-value 50\npython scripts/tool_roi_calculator.py --build-cost 5000 --monthly-traffic 2000 --conversion-rate 8 --lead-value 50 --json\n```\n\n| Flag | Required | Description |\n|------|----------|-------------|\n| `--build-cost` | Yes | Total build cost in dollars (engineering time + design) |\n| `--monthly-traffic` | Yes | Expected monthly sessions after 90 days |\n| `--conversion-rate` | Yes | Expected lead conversion rate as percentage |\n| `--lead-value` | Yes | Dollar value per captured lead |\n| `--monthly-hosting` | No | Monthly hosting/maintenance cost (default: 50) |\n| `--json` | No | Output results as JSON |\n\n### 3. launch_checklist_generator.py\n\n**Purpose:** Generate a phased launch checklist (pre-launch, launch week, post-launch) customized to the tool type and distribution channels.\n\n```bash\npython scripts/launch_checklist_generator.py --tool-type calculator --channels seo,producthunt,social\npython scripts/launch_checklist_generator.py --tool-type checker --channels seo,email --json\n```\n\n| Flag | Required | Description |\n|------|----------|-------------|\n| `--tool-type` | Yes | Tool type: calculator, generator, checker, grader, converter, template, visualization |\n| `--channels` | No | Comma-separated launch channels (default: seo,social,email) |\n| `--json` | No | Output results as JSON |\n\n---\n\n## Troubleshooting\n\n| Problem | Likely Cause | Solution |\n|---------|-------------|----------|\n| High traffic to tool but low lead capture | Gate is too aggressive or positioned before value delivery | Show core results first, then gate the detailed report or export; use email-only capture form |\n| Tool built but no organic traffic after 3 months | SEO landing page is thin or keywords are too competitive | Add 1500+ words of supporting content (how it works, use cases, FAQ); target long-tail keywords |\n| Tool is used once but users do not return | No recurring value or no save/bookmark mechanism | Add saved results, email reports, or periodic re-run reminders; consider a \"monitor\" mode |\n| Build cost exceeded estimate | Scope creep during development | Use tool_roi_calculator.py upfront to set budget ceiling; define MVP scope and ship in 2 weeks max |\n| Product Hunt launch got minimal traction | Poor timing or weak positioning | Launch Tuesday-Thursday; lead with the user benefit, not the technology; get 5+ early upvotes from network |\n| Tool generates leads but low conversion to paid | Tool attracts wrong audience or no connection to paid product | Ensure the tool solves a problem your paid product also addresses; add contextual upgrade prompts |\n\n---\n\n## Success Criteria\n\n- Tool scores 20+ on the 6-factor evaluation framework before committing to build\n- Tool achieves 500+ monthly sessions within 90 days of launch\n- Lead conversion rate of 5-15% of tool completions\n- Tool earns 10+ organic backlinks within 6 months\n- Break-even achieved within 6 months (verified by tool_roi_calculator.py)\n- Completion rate above 60% (users who start using the tool finish the workflow)\n- At least 1 supporting blog post and social launch content published at launch\n\n---\n\n## Scope & Limitations\n\n- **In scope:** Tool idea evaluation, ROI modeling, launch planning, distribution strategy, lead capture architecture, SEO landing page strategy, measurement framework\n- **Out of scope:** Engineering implementation, design/UI work, paid advertising strategy, AI/ML-powered tool features\n- **Build constraint:** All tools should be buildable in 1-4 weeks; if longer, the scope is too large for a free marketing tool\n- **Maintenance cost:** Every tool requires ongoing maintenance (monthly checks, quarterly content updates); budget for this before building\n- **No API dependencies:** Free tools should use client-side logic where possible to avoid ongoing API costs and reliability issues\n\n---\n\n## Integration Points\n\n- **form-cro** -- Use for optimizing the lead capture form embedded within the free tool\n- **page-cro** -- Use for optimizing the SEO landing page that hosts the tool for conversion\n- **seo-audit** -- Use for validating the tool landing page meets technical SEO requirements\n- **content-creator** -- Use for writing the launch blog post, social content, and outreach emails\n- **schema-markup** -- Use for implementing SoftwareApplication and FAQPage schema on the tool page","author":"@borghei","ownerProfile":null,"authorContacts":null,"sourceUrl":"https://github.com/borghei/Claude-Skills/tree/main/business-growth/free-tool-strategy","license":"MIT","category":"design","lang":"en","tokens":4442,"stars":0,"calls30d":2,"claimed":false,"visibility":"public","origin":"crawler","version":"0.1.0","createdAt":"2026-08-22","updatedAt":"2026-08-22","files":[{"path":"scripts/launch_checklist_generator.py","size":10327,"sha256":"e00405971bff5c646c35bb3faadb4921aa8bf86f223c107071097b52b529b4b6"},{"path":"scripts/tool_idea_scorer.py","size":6787,"sha256":"aef85f51dd02fff819a2659ca8958ff6ba42cd1610c0c16f02ed0377fb1db0ec"},{"path":"scripts/tool_roi_calculator.py","size":9229,"sha256":"0a5f1fc765f20f5356c6749116aa3e7bf0b0cdb5b6276122ded3feb13a11c002"}],"requires":{"mcp":[],"tools":[]},"safety":{"flags":[],"scannedAt":"2026-08-22","hasScripts":true,"networkEndpoints":[]}}
