Run an SEO audit of your blog with Claude Code and a browser

Developer Alexander Opalic tested Claude Code as an SEO auditor on NuxtPapier, a Nuxt blog starter he maintains. He connected the Puppeteer MCP server so the agent could open the running site in a real browser. His prompt asked it to act as an SEO expert and check the pages. The agent wrote its own task list, visited pages, read meta tags and page source, and returned a report. It caught serious problems: a noindex, nofollow meta tag, a robots.txt that turned away every crawler, and repeated H1 headings. It also noted what was fine, like structured data, mobile layout and loads around 200ms. The report named which files to fix. He shared no traffic or ranking change after the fixes.
