What problem does it solve? Deciding whether to build a free marketing tool (calculator, generator, checker, grader) is risky without data — teams waste engineering time on tools nobody searches for, gate them too early, or launch without distribution. This Skill provides a structured framework to evaluate ideas, design for lead capture and shareability, and execute a launch that earns traffic and backlinks. ## Core Features & Use Cases - 6-Factor Idea Evaluation: Score tool ideas on search volume, competition, build effort, lead capture potential, SEO value, and viral potential to decide what to build first. - Tool Design Guidance: Covers 7 tool types (calculators, generators, checkers, graders, converters, templates, visualizations) with UX, lead gating, and shareable-output principles. - Launch & Measurement Playbook: Pre-launch SEO checklist, Product Hunt/Hacker News sequencing, backlink outreach templates, and 90-day KPI targets. - ROI Modeling: Run the included Python estimator to project break-even month, cost per lead, and minimum traffic needed. - Use Case: A SaaS team wants to build a free ROI calculator to generate leads. Use this Skill to validate the keyword opportunity, design the lead capture flow, write the landing page, and model whether the build cost pays back within 12 months. ## Quick Start Ask the assistant to evaluate your free tool ideas against the 6-factor framework and recommend which one to build first.
