What is a marketing skill?

A marketing skill is a reusable instruction file that teaches an AI assistant like Claude or ChatGPT to do one marketing job well — write a positioning statement, build an SEO brief, plan a launch, read your attribution. Unlike a one-off prompt, a skill defines the inputs it needs, the method to follow, the exact output format and the quality checks to pass, so the whole team gets consistent work instead of generic copy.

The difference that matters most in marketing is what a skill refuses to make up. Assistants confidently invent search volumes, benchmarks and customer proof: in one public test, ChatGPT put the monthly searches for "seo" at 6,600 when Ahrefs measured 191,000. Every skill here works only from what you paste — your data, your proof, your customers' words — and flags what's missing instead of filling the gap.

Skills use an open format — a single SKILL.md file — that Claude, ChatGPT, OpenAI's Codex, Gemini CLI, Cursor and 20+ other tools now run natively, and every skill also ships as a paste-once ChatGPT Project version under the 8,000-character limit. No integrations required: if your assistant has web search or connectors it will use them, but no skill depends on them.

How to install these skills

In Claude

  1. 1Download the skill's .zip from its page — it contains the SKILL.md file.
  2. 2On claude.ai, open Settings → Features (Capabilities on some plans), make sure code execution is on, and upload the zip under Skills.
  3. 3In Claude Code, unzip it into ~/.claude/skills/ instead — or .claude/skills/ inside a repo to share it with your team.
  4. 4Then just describe the task. Claude loads the matching skill automatically; you never invoke it by name.

In ChatGPT

  1. 1Copy the skill's ChatGPT version — every one fits ChatGPT's 8,000-character Project instructions limit.
  2. 2Create a Project named after the skill, paste it into the Project's instructions, and run every task of that type inside that Project.
  3. 3On plans with ChatGPT Skills, you can instead paste the SKILL.md body under Plugins → Skills and invoke it with @skill-name.

The same files work in Gemini, Copilot and any assistant that accepts long instructions — SKILL.md is an open standard. One thing not to do: don't wrap these as custom GPTs, which OpenAI retires in December 2026.

Get the whole library as one pack

All 20 skills in both formats — SKILL.md files ready for Claude plus every ChatGPT version — in one zip, with a README that maps each skill to the moment in your quarter you'd reach for it.

Instant download. We'll email you only when new skills land — no sequences, no surprise SDR follow-up.

What is a marketing skill?

A marketing skill is a reusable instruction file that teaches an AI assistant like Claude or ChatGPT how to do one marketing job well — positioning, an SEO brief, a launch plan, an attribution readout. Unlike a one-off prompt, it defines the inputs, the method and the exact output format, so results stay consistent across the team.

Do these skills work with ChatGPT or only with Claude?

Both. Every skill ships in two formats: a SKILL.md file you upload to Claude (claude.ai, Claude Code or the API) and a version sized for a ChatGPT Project's 8,000-character instructions field. SKILL.md itself is an open standard that ChatGPT's Skills feature, OpenAI's Codex, Gemini CLI and 20+ other tools also read, so one download covers most of your stack.

How do I install a Claude skill?

Download the skill's zip and upload it on claude.ai under Settings → Features → Skills (code execution must be enabled). In Claude Code, unzip it into ~/.claude/skills/ instead. Claude then loads the skill automatically whenever your request matches its description — you don't call it by name.

Are the skills really free?

Yes. Every skill on this page is free to read, copy, download and adapt — no sign-up. The optional all-in-one pack asks for a work email so we can tell you when new skills are added; that is the only gate anywhere in the library.

How is a skill different from a prompt?

A prompt is a one-off instruction; a skill is a packaged workflow. A skill carries a when-to-use description, required inputs, a step-by-step method, an output template and quality rules (like "never invent facts that aren't in the transcript"), so anyone on the team gets the same result without prompt-crafting. Assistants also load skills automatically when the task matches, which a pasted prompt can't do.

Can I use these as a custom GPT?

We don't recommend it. OpenAI announced that custom GPTs retire on December 11, 2026, with their instructions migrating into plugin skills. Use a ChatGPT Project (works on every plan) or ChatGPT Skills (business plans) instead — both paths are covered on every skill page here.

Will these skills invent statistics or search volumes?

No — that's the rule they're built around. Search volumes, benchmarks, conversion rates and customer proof come only from what you paste or what a connected tool returns. Anything missing is marked as a gap with a [NEED: …] flag, because a brief or board report built on invented numbers is worse than one with an honest blank.
