# Free Tool Strategy

## Before Starting

**Check for context first:**
If `.claude/product-marketing-context.md` exists, read it before asking questions. Use that context and only ask for information not already covered.

Gather this context (ask if not provided):

### 1. Product & Audience
- What's your core product and who buys it?
- What problem does your ideal customer have that a free tool could solve adjacently?
- What does your audience search for that isn't your product?

### 2. Resources
- How much engineering time can you dedicate? (Hours, days, weeks)
- Do you have design resources, or is this no-code/template?
- Who maintains the tool after launch?

### 3. Goals
- Primary goal: SEO traffic, lead generation, backlinks, or brand awareness?
- What does a "win" look like? (X leads/month, Y backlinks, Z organic visitors)

## How This Skill Works

### Mode 1: Evaluate Tool Ideas
You have one or more ideas and you're not sure which to build — or whether to build any of them.

**Workflow:**
1. Score each idea against the 6-factor evaluation framework
2. Identify the highest-potential idea based on your specific goals and resources
3. Validate with keyword data before committing engineering time

### Mode 2: Design the Tool
You've decided what to build. Now design it to maximize value, lead capture, and shareability.

**Workflow:**
1. Define the core value exchange (what the user inputs → what they get back)
2. Design the UX for minimum friction
3. Plan lead capture: where, what to ask, progressive profiling
4. Design shareable output (results page, generated report, embeddable badge)
5. Plan the SEO landing page structure

### Mode 3: Launch and Measure
You've built it. Now distribute it and track whether it's working.

**Workflow:**
1. Pre-launch: SEO landing page, schema markup, submit to directories
2. Launch channels: Product Hunt, Hacker News, industry newsletters, social
3. Outreach: who links to similar tools? → build a link acquisition list
4. Measurement: set up tracking for usage, leads, organic traffic, backlinks
5. Iterate: usage data tells you what to improve

## Tool Types and When to Use Each

| Tool Type | What It Does | Build Complexity | Best For |
|-----------|-------------|-----------------|---------|
| **Calculator** | Takes inputs, outputs a number or range | Low–Medium | LTV, ROI, pricing, salary, savings |
| **Generator** | Creates text, ideas, or structured content | Low (template) – High (AI) | Headlines, bios, copy, names, reports |
| **Checker** | Analyzes a URL, text, or file and scores/audits it | Medium–High | SEO audit, readability, compliance, spelling |
| **Grader** | Scores something against a rubric | Medium | Website grade, email grade, sales page score |
| **Converter** | Transforms input from one format to another | Low–Medium | Units, formats, currencies, time zones |
| **Template** | Pre-built fillable documents | Very Low | Contracts, briefs, decks, roadmaps |
| **Interactive Visualization** | Shows data or concepts visually | High | Market maps, comparison charts, trend data |

See references/tool-types-guide.md for detailed examples, build guides, and complexity breakdowns per type.

## The 6-Factor Evaluation Framework

Score each idea 1–5 on each factor. Highest total = build first.

| Factor | What to Check | 1 (weak) | 5 (strong) |
|--------|--------------|----------|-----------|
| **Search Volume** | Monthly searches for "free [tool]" | <100/mo | >5k/mo |
| **Competition** | Quality of existing free tools | Excellent tools exist | No good free alternatives |
| **Build Effort** | Engineering time required | Months | Days |
| **Lead Capture Potential** | Can you naturally gate or capture email? | Forced gate, kills UX | Natural fit (results emailed, report downloaded) |
| **SEO Value** | Can you build topical authority + backlinks? | Thin, one-page utility | Deep use case, link magnet |
| **Viral Potential** | Will users share results or embed the tool? | Nobody shares | Results are shareable by design |

**Scoring guide:**
- 25–30: Build it, now
- 18–24: Strong candidate, validate keyword volume first
- 12–17: Maybe, if resources are low or it fits a strategic gap
- <12: Pass, or rethink the concept

## Design Principles

### Value Before Gate
Give the core value first. Gate the upgrade — the deeper report, the saved results, the email delivery. If the tool is only valuable after they give you their email, you've designed a lead form, not a tool.

**Good:** Show the score immediately → offer to email the full report
**Bad:** "Enter your email to see your results"

### Minimal Friction
- Max 3 inputs to get initial results
- No account required for the core value
- Progressive disclosure: simple first, detailed on request
- Mobile-optimized — 50%+ of tool traffic is mobile

### Shareable Results
Design results so users want to share them:
- Unique results URL that others can visit
- "Tweet your score" / "Copy your results" buttons
- Embed code for badges or widgets
- Downloadable report (PDF or CSV)
- Social-ready image generation (score card, certificate)

### Mobile-First
- Inputs work on touch screens
- Results render cleanly on mobile
- Share buttons trigger native share sheet
- No hover-dependent UI

## Lead Capture — When, What, How

### When to Gate

**Gate with email when:**
- Results are complex enough to warrant a "report" framing
- Tool produces ongoing value (track over time, re-run monthly)
- Results are personalized and users would naturally want to save them

**Don't gate when:**
- Core result is a single number or short answer
- Competition offers the same thing without a gate
- Your primary goal is SEO/backlinks (gates hurt time-on-page and links)

### What to Ask

Ask the minimum. Every field drops completion by ~10%.

**First gate:** Email only
**Second gate (on re-use or report download):** Name + Company size + Role

### Progressive Profiling
Don't ask everything at once. Build the profile over multiple sessions:
- Session 1: Email to save results
- Session 2: Role, use case (asked contextually, not in a form)
- Session 3: Company, team size (if they request team features)

## SEO Strategy for Free Tools

### Landing Page Structure

```
H1: [Free Tool Name] — [What It Does] [one phrase]
Subhead: [Who it's for] + [what problem it solves]
[The Tool — above the fold]
H2: How [Tool Name] works
H2: Why [audience] use [tool name]
H2: [Related Question 1]
H2: [Related Question 2]
H2: Frequently Asked Questions
```

Target keyword in: H1, URL slug, meta title, first 100 words, at least 2 subheadings.

### Schema Markup
Add `SoftwareApplication` schema to tell Google what the page is:
```json
{
  "@type": "SoftwareApplication",
  "name": "Tool Name",
  "applicationCategory": "BusinessApplication",
  "offers": {"@type": "Offer", "price": "0"},
  "description": "..."
}
```

### Link Magnet Potential
Tools attract links from:
- Resource pages ("best free tools for X")
- Blog posts ("the tools I use for X")
- Subreddits, Slack communities, Facebook groups
- Weekly newsletters in your niche

Plan your outreach list before launch. Who writes about tools in your category? Find their existing "best tools" posts and reach out post-launch.

## Measurement

Track these from day one:

| Metric | What It Tells You | Tool |
|--------|------------------|------|
| Tool usage (sessions, completions) | Is anyone using it? | GA4 / Plausible |
| Lead conversion rate | Is it generating leads? | CRM + GA4 events |
| Organic traffic | Is it ranking? | Google Search Console |
| Referring domains | Is it earning links? | Ahrefs / Google GSC |
| Email to paid conversion | Is it generating pipeline? | CRM attribution |
| Bounce rate / time on page | Is the tool actually used? | GA4 |

**Targets at 90 days post-launch:**
- Organic traffic: 500+ sessions/month
- Lead conversion: 5–15% of completions
- Referring domains: 10+ organic backlinks

Run `scripts/tool_roi_estimator.py` to model break-even timeline based on your traffic and conversion assumptions.

## Proactive Triggers

Surface these without being asked:

- **Tool requires account before use** → Flag and redesign the gate. This kills SEO, kills virality, and tells users you're harvesting data, not providing value.
- **No shareable output** → If results exist only in the session and can't be shared or saved, you've built half a tool. Flag the missed virality opportunity.
- **No keyword validation** → If the tool concept hasn't been validated against search volume before build, flag — 3 hours of research beats 3 weeks of building a tool nobody searches for.
- **Competitors with the same free tool** → If an existing tool is well-established and free, the bar is "10x better or don't build it." Flag the competitive risk.
- **Single input → single output** → Ultra-simple tools lose SEO value quickly and attract no links. Flag if the tool needs more depth to be link-worthy.
- **No maintenance plan** → Free tools die when the API they call changes or the logic gets stale. Flag the need for a maintenance owner before launch.

## Output Artifacts

| When you ask for... | You get... |
|---------------------|------------|
| "Evaluate my tool ideas" | Scored comparison matrix (6 factors × ideas), ranked recommendation with rationale |
| "Design this tool" | UX spec: inputs, outputs, lead capture flow, share mechanics, landing page outline |
| "Write the landing page" | Full landing page copy: H1, subhead, how it works section, FAQ, meta title + description |
| "Plan the launch" | Pre-launch checklist, launch channel list with specific actions, outreach target list |
| "Set up measurement" | GA4 event tracking plan, GSC setup checklist, KPI targets at 30/60/90 days |
| "Is this tool worth building?" | ROI model (using tool_roi_estimator.py): break-even month, required traffic, lead value threshold |

---

## Communication

All output follows the structured communication standard:
- **Bottom line first** — recommendation before reasoning
- **Numbers-grounded** — traffic targets, conversion rates, ROI projections tied to your inputs
- **Confidence tagging** — 🟢 validated / 🟡 estimated / 🔴 assumed
- **Build decisions are binary** — "build it" or "don't build it" with a clear reason, not "it depends"

## Operating boundary

Apply the workflow to information supplied by the user or obtained through approved Aident connections. Do not install packages, run copied scripts, or assume local project files mentioned by the upstream workflow exist. Present drafts and plans for review before any externally visible, paid, account-changing, or destructive action.
