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 |
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 |
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 sheet
- No hover-dependent UI elements
Lead Capture Architecture
When to Gate
| Gate Decision | Criteria |
|---|
| Gate with email | Results are complex (report format), ongoing value (re-run monthly), personalized output |
| Do NOT gate | Core result is a single number, competition offers the same ungated, primary goal is SEO/backlinks |
Progressive Capture
Do not ask for everything at once. Build the profile over multiple interactions.
| Interaction | What to Capture | How |
|---|
| First use | Email (to save or email results) | Inline form after results display |
| Return use | Name + Role | Contextual prompt, not a blocking form |
| Repeated use | Company + Team size | If they request team features or saved history |
Capture Form Design
- Email-only first gate (single field + submit button)
- Position the form AFTER results are shown (not before)
- Explain the value: "Email me a detailed breakdown" not "Sign up"
- Privacy text: "We'll send your report. No spam."
- Never require account creation for the free tool
SEO Landing Page Strategy
Page Structure
H1: Free [Tool Name] -- [What It Does in One Phrase]
Subhead: [Who it is for] + [what problem it solves]
[THE TOOL -- above the fold, interactive]
H2: How [Tool Name] Works
(3-4 steps with screenshots)
H2: Why [Audience] Use [Tool Name]
(Benefits, use cases, 3-5 paragraphs)
H2: [Related Question 1] (FAQ-style, keyword-targeted)
H2: [Related Question 2]
H2: [Related Question 3]
H2: Frequently Asked Questions
(5-7 FAQs with FAQPage schema)
SEO Requirements
- Target keyword in: H1, URL slug, meta title, first 100 words, 2+ subheadings

"offers": {
"@type": "Offer",
"price": "0",

Measurement Framework
Key Metrics
| Metric | What It Tells You | Target (90 days) |
|---|
| Tool usage (sessions) | Is anyone using it? | 500+ sessions/month |
| Completion rate | Do users finish using it? | > 60% |
| Lead conversion rate | Is it generating leads? | 5-15% of completions |
| Organic traffic | Is it ranking? | 500+ sessions/month from organic |
| Referring domains | Is it earning backlinks? | 10+ organic backlinks |
| Email to pipeline rate | Is it generating qualified leads? | Track in CRM |
| Bounce rate | Is the tool engaging? | < 50% |
ROI Calculation
Monthly Cost = Engineering hours x Hourly rate + Hosting cost
Monthly Value = (Leads x Lead-to-Customer Rate x ACV) + (Backlink value estimate)
Break-even month = Total build cost / Monthly value
Target: Break-even within 6 months
Maintenance and Iteration
Ongoing Maintenance Requirements
| Task | Frequency | Why |
|---|
| Check for broken APIs/data sources | Monthly | External dependencies change |
| Update calculations/logic if standards change | As needed | Accuracy maintains trust |
| Review and fix UX issues from user feedback | Quarterly | Continuous improvement |
| Update SEO landing page content | Semi-annually | Content freshness |
| Check analytics for usage trends | Monthly | Identify optimization opportunities |
Iteration Based on Data
| Signal | Action |
|---|
| High usage, low lead capture | Improve gate positioning or offer |
| Low usage, high search ranking | Improve tool UX and value |
| High leads, low quality | Add qualifying questions to capture form |
| High bounce rate | Improve above-fold messaging and tool visibility |
| Low search ranking | Improve page content depth and backlink acquisition |
Output Artifacts
| Artifact | Format | Description |
