What problem does it solve? Deciding whether to build a free tool (calculator, generator, analyzer) as a marketing channel is risky without a framework. This Skill provides a structured strategy for ideating, validating, scoping, and evaluating free tools that generate leads, organic traffic, and backlinks. ## Core Features & Use Cases - Ideation & Validation Framework: Start from audience pain points, search demand, and competitive uniqueness to pick tool ideas worth building. - Tool Type Taxonomy: Covers calculators, generators, analyzers, testers, libraries, and interactive tools, with a detailed reference file of examples by industry. - Lead Capture & SEO Strategy: Compares gating options (fully gated, partially gated, ungated) and outlines keyword and link-building approaches. - Evaluation Scorecard: Rates ideas across eight factors (search demand, audience match, feasibility, link potential) with a 25+ scoring threshold. - Use Case: A SaaS founder asks whether to build an ROI calculator. The Skill walks through demand validation, MVP scoping, lead capture design, and scores the idea against the scorecard before any code is written. ## Quick Start Help me evaluate whether building a free ROI calculator is a good lead generation strategy for my SaaS product.
