NotFair Plugin
45 open SEO, GEO, content, and ads skills for coding agents, plus a hosted MCP for live ad and analytics accounts.
Free · Growth: $79 per month
- I want my coding agent to audit my site and write the fixes and content, using procedures I can read and tune
- I manage ad accounts and want an agent to find wasted spend and propose changes I approve
- Publish the content it writes
- Skills that touch live accounts need the hosted NotFair MCP: 7 days unlimited, then 300 operations per month on the free tier
- The hosted MCP is where account data flows; the open repo is the procedures, not the connector
- Vertical fit is marketing and SEO more than publishing; only the content-writer and GEO skills produce publishable material
- Renamed from TopRank after its Show HN; older references use the old name
SEOmator SEO Audit
332-rule SEO audit as a CLI, desktop app, and Claude Code skill, tuned by a seomator.toml.
Free · SEOmator hosted
- I want my agent to audit a site and hand me a prioritized fix list before I publish
- I want an SEO check in CI that fails the build when a page regresses
- Track score history over time
- Use the hosted SEOmator web audit
- Core Web Vitals need a system Chrome, Chromium, or Edge; use --no-cwv on headless boxes without one
- Desktop app needs electron-rebuild for the native SQLite module
- Vertical fit is SEO tooling rather than publishing; it audits pages, it does not publish them
