- License: MIT, core closed

- Reach: 9 of 10 jobs
- Last activity: 2026-08-29
- Effort: config-only
- Agent cannot reach: Publish the content it writes
- Use it when: I want my coding agent to audit my site and write the fixes and content, using procedures I can read and tune
- Use it when: I manage ad accounts and want an agent to find wasted spend and propose changes I approve
- Gotcha: Skills that touch live accounts need the hosted NotFair MCP: 7 days unlimited, then 300 operations per month on the free tier
- Gotcha: The hosted MCP is where account data flows; the open repo is the procedures, not the connector
- Gotcha: Vertical fit is marketing and SEO more than publishing; only the content-writer and GEO skills produce publishable material
- Gotcha: Renamed from TopRank after its Show HN; older references use the old name

## SEOmator SEO Audit

- License: MIT
- Agent interface: CLI, from the builder
- Reach: 8 of 10 jobs
- Last activity: 2026-09-02
- Effort: config-only
- Agent cannot reach: Track score history over time; Use the hosted SEOmator web audit
- Use it when: I want my agent to audit a site and hand me a prioritized fix list before I publish
- Use it when: I want an SEO check in CI that fails the build when a page regresses
- Gotcha: Core Web Vitals need a system Chrome, Chromium, or Edge; use --no-cwv on headless boxes without one
- Gotcha: Desktop app needs electron-rebuild for the native SQLite module
- Gotcha: Vertical fit is SEO tooling rather than publishing; it audits pages, it does not publish them
