Give this a URL and it runs a structured SEO audit across five weighted categories: crawlability, technical foundations, on-page optimization, content quality, and authority signals. It fetches the page HTML, checks robots.txt and sitemaps, hits the PageSpeed API for Core Web Vitals, then scores each category using a severity-based system (critical issues cost 25 points, high 15, and so on). The output is a scored report with issues prioritized by impact and effort, plus a quick wins section. Honest take: the scoring rubric is thorough and the categorization makes sense, though you'll need web fetch capabilities and API access to get real value from it.
