Marketing Skills: pricing, features, alternatives

Marketing Skills is a loadable agent-skill library for conversion optimization, copywriting, SEO, analytics, and growth engineering. The site is marketing-skills.com. The GitHub repo coreyhaines31/marketingskills is MIT, created 2026-01-15, JavaScript. On 2026-09-07 GitHub listed about 47,520 stars and 7,388 forks. Homepage copy says 50 skills and install via npx skills add coreyhaines31/marketingskills for Claude Code, Codex, and Cursor. Built by Corey Haines. This is a SKILL.md pack, not a YouMind marketplace Skill.

Compare Claude SEO if you wanted a dedicated SEO audit orchestrator, OpenSEO if you needed live keyword and backlink data, or Claude Skills if you still needed how skills load.

Key Features

50 skills: Site groups include ai-seo, seo-audit, programmatic-seo, schema, site-architecture, content-strategy, and directory-submissions, plus CRO, ads, lifecycle, growth, strategy, and research.
Shared product context: README says product-marketing is the foundation. Other skills read it first for product, audience, and positioning.
Cross-agent install: Works with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that supports the Agent Skills spec.
Tool registry with disclosed partners: README lists Converly and Ploy as verified partners that fund the library. Partner rules live in tools/PARTNERS.md. Core skill recommendations are supposed to stay independent of that block.
Release cadence: Homepage pointed at v2.11.1 on 2026-09-07, including an ai-seo reference update.

Limitation: fifty skills is a lot of context. Loading the whole pack without a marketing brief still produces generic copy. Partner tools are disclosed, not secret, but they are still paid products sitting next to free skills.

Use Cases

Technical marketers and founders who already run Claude Code or Cursor and want CRO, SEO, and ads workflows in the repo.
Indie builders shipping landing pages who want product-marketing as a single source of positioning.
Agencies that will keep the MIT skills and buy implementation from Conversion Factory or Magister only if they want it done for them.
