SEO agencies charge $400 to $2,500 a month, and most of what they do is a public checklist. This free Claude skill, nearly 1,000 GitHub stars, runs that checklist on your site: it reads your pages the way a search crawler does, grades them on five tests, fixes what you approve, and measures again two weeks later. Its maker used the same playbook on their own site and got 1.54 million search impressions in 30 days with zero ad spend.
Here's what it checks, how to run it on your site in Claude Code, and the honest catch.
The five tests it grades your site on
- SEO: can Google and Bing read and index your pages at all? (sitemap, titles, descriptions, structured data)
- AEO: does the AI answer box above Google's results quote you?
- GEO: when ChatGPT, Perplexity or Claude browse, are you the source they cite? (llms.txt, citation-ready paragraphs)
- LLMO: does the AI model know your brand, and spell it the same way everywhere?
- NEO: Naver, Korea's search engine (skip it if you don't sell in Korea).
It checks the worst mistake first: a leftover "noindex" setting that tells Google to skip your whole site. One line like that cancels every other fix.
Run it on your site (10 minutes)
- Open your website's project folder in Claude Code (it needs a paid Claude plan).
- Install the skill: type /plugin marketplace add leopard627/fire-your-seo-agency, then /plugin install fire-your-seo-agency@fire-your-seo-agency.
- Type /fire-your-seo-agency audit my site, with your web address.
- Read the scorecard and the fix list it proposes, and say yes to the ones you want.
- Put the re-check date it gives you in your calendar, and run it again then.
