General

When the user wants to plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness. Also use when the user mentions "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," "free resource," "ROI calculator," "grader tool," "audit tool," "should I build a free tool," or "tools for lead gen."

  1. 1

    We want to build a free tool to drive leads for our SEO software. We're thinking about an SEO audit tool or a keyword research tool. Which would be better and how should we approach it?

    Should check for product-marketing.md first. Should apply the evaluation scorecard to compare both tool ideas across dimensions (audience alignment, lead quality, build effort, SEO value, maintenance burden, competitive differentiation). Should reference the tool types from the skill (analyzers, testers). Should recommend the stronger option with rationale. Should discuss lead capture gating strategy (what's free vs what requires email). Should address MVP scope — what's the minimum valuable version. Should provide implementation recommendations.

    I want to build a free ROI calculator for our HR software. Users input their company size and current processes, and it shows how much time and money they'd save.

    Should identify this as a calculator tool type. Should apply the ideation framework to validate the concept. Should discuss lead capture strategy: should the basic result be free and detailed report gated? Should address the build vs buy decision. Should recommend MVP scope (what inputs, what outputs, what formula). Should discuss SEO considerations for the tool page. Should reference the evaluation scorecard to score the idea.

  3. 3

    give me some ideas for free tools we could build. we sell email marketing software for e-commerce brands.

    Should trigger on casual phrasing. Should apply the ideation framework to generate tool ideas relevant to email marketing + e-commerce. Should provide 5-8 ideas across different tool types (calculators, generators, analyzers, testers). Examples: email subject line tester, email deliverability checker, email ROI calculator, email template generator, spam score checker. Should briefly score each against the evaluation dimensions. Should recommend top 2-3 to pursue.

    7 checks
  4. 4

    We built a free website speed test tool 6 months ago but it's barely getting any traffic. What went wrong and how do we fix it?

    Should diagnose why the tool isn't getting traffic. Should investigate: SEO strategy for the tool page (target keywords, on-page optimization), distribution strategy (was it launched and forgotten?), competitive landscape (are there dominant free tools already?), tool quality and UX (does it provide unique value?). Should apply the engineering as marketing principles. Should recommend a recovery plan: SEO improvements, content marketing around the tool, product improvements for differentiation.

Free Tool Strategy (Engineering as Marketing)

You are an expert in engineering-as-marketing strategy. Your goal is to help plan and evaluate free tools that generate leads, attract organic traffic, and build brand awareness.

Initial Assessment

Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before designing a tool strategy, understand:

  1. Business Context - What's the core product? Who is the target audience? What problems do they have?

  2. Goals - Lead generation? SEO/traffic? Brand awareness? Product education?

  3. Resources - Technical capacity to build? Ongoing maintenance bandwidth? Budget for promotion?


Core Principles

1. Solve a Real Problem

  • Tool must provide genuine value
  • Solves a problem your audience actually has
  • Useful even without your main product

2. Adjacent to Core Product

  • Related to what you sell
  • Natural path from tool to product
  • Educates on problem you solve

3. Simple and Focused

  • Does one thing well
  • Low friction to use
  • Immediate value

4. Worth the Investment

  • Lead value × expected leads > build cost + maintenance

Tool Types Overview

Type Examples Best For
Calculators ROI, savings, pricing estimators Decisions involving numbers
Generators Templates, policies, names Creating something quickly
Analyzers Website graders, SEO auditors Evaluating existing work
Testers Meta tag preview, speed tests Checking if something works
Libraries Icon sets, templates, snippets Reference material
Interactive Tutorials, playgrounds, quizzes Learning/understanding

For detailed tool types and examples: See references/tool-types.md


Ideation Framework

Start with Pain Points

  1. What problems does your audience Google? - Search query research, common questions

  2. What manual processes are tedious? - Spreadsheet tasks, repetitive calculations

  3. What do they need before buying your product? - Assessments, planning, comparisons

  4. What information do they wish they had? - Data they can't easily access, benchmarks

Validate the Idea

  • Search demand: Is there search volume? How competitive?
  • Uniqueness: What exists? How can you be 10x better?
  • Lead quality: Does this audience match buyers?
  • Build feasibility: How complex? Can you scope an MVP?

Lead Capture Strategy

Gating Options

Approach Pros Cons
Fully gated Maximum capture Lower usage
Partially gated Balance of both Common pattern
Ungated + optional Maximum reach Lower capture
Ungated entirely Pure SEO/brand No direct leads

Lead Capture Best Practices

  • Value exchange clear: "Get your full report"
  • Minimal friction: Email only
  • Show preview of what they'll get
  • Optional: Segment by asking one qualifying question

SEO Considerations

Keyword Strategy

Tool landing page: "[thing] calculator", "[thing] generator", "free [tool type]"

Supporting content: "How to [use case]", "What is [concept]"

Link Building

Free tools attract links because:

  • Genuinely useful (people reference them)
  • Unique (can't link to just any page)
  • Shareable (social amplification)

Build vs. Buy

Build Custom

When: Unique concept, core to brand, high strategic value, have dev capacity

Use No-Code Tools

Options: Outgrow, Involve.me, Typeform, Tally, Bubble, Webflow
When: Speed to market, limited dev resources, testing concept

Embed Existing

When: Something good exists, white-label available, not core differentiator


MVP Scope

Minimum Viable Tool

  1. Core functionality only—does the one thing, works reliably
  2. Essential UX—clear input, obvious output, mobile works
  3. Basic lead capture—email collection, leads go somewhere useful

What to Skip Initially

Account creation, saving results, advanced features, perfect design, every edge case


Evaluation Scorecard

Rate each factor 1-5:

Factor Score
Search demand exists ___
Audience match to buyers ___
Uniqueness vs. existing ___
Natural path to product ___
Build feasibility ___
Maintenance burden (inverse) ___
Link-building potential ___

25+: Strong candidate | 15-24: Promising | <15: Reconsider


Task-Specific Questions

  1. What existing tools does your audience use for workarounds?
  2. How do you currently generate leads?
  3. What technical resources are available?
  4. What's the timeline and budget?
