Plan a free tool (calculator, checker, generator) that earns links, rankings and leads. Use when the user says things like "should we build a free tool"; "ideas for a free calculator for our site"; "engineering as marketing"; "which free tool should we build first"; "our free tool gets traffic but no leads"; "how do we promote a free tool".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Free tools as marketing Plans a small, genuinely useful free tool (a calculator, checker, grader, generator, template or converter) that people search for, link to and come back to, and that leads naturally to the paid product. The winners are usually tiny and focused; the losers are over-built, unrelated to what the company sells, or gated so hard they become a disguised form. The result is a scored idea list, a buildable spec, the landing page plan, and a launch and measurement plan. ## When to use - "Should we build a free tool?", "calculator ideas", "which tool first?", "our tool gets traffic but no leads". - Looking for a link-earning asset for SEO, or a lead source that is not another PDF. - Not for: downloadable lead magnets such as guides and templates only (`cmo-lead-magnets`), many template-driven SEO pages (`cmo-programmatic-seo`), or the tool's page conversion (`cmo-page-cro`). ## Before you start - Ask, one at a time: what you sell and to whom; the main goal; who can build and maintain it; deadline; any keyword data or tools competitors already offer. …

How to install
mdr add ai-marketing-os-ltd/cmo-so-skills/cmo-free-tools@sha256:c1d5bd95eb8c8318The line at the top of this page pins the label v0.15.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
