What problem does it solve? Technical SEO issues like blocked crawlers, missing canonical tags, slow Core Web Vitals, and misconfigured security headers silently hurt search rankings, but finding them requires checking dozens of signals across a site. This Skill runs a structured audit across nine categories and produces a prioritized, scored report. ## Core Features & Use Cases - Nine-Category Audit: Covers crawlability, indexability, security, URL structure, mobile, Core Web Vitals, structured data, JavaScript rendering, and IndexNow, each scored out of 100. - AI Crawler Management: Evaluates robots.txt rules for AI crawlers like GPTBot, ClaudeBot, and Google-Extended, with guidance on blocking training versus preserving AI search visibility. - Agent-Friendly Page Analysis: Uses Playwright-based scripts to capture the accessibility tree and score how well AI agents can interpret and interact with pages. - Use Case: Run an audit on a Next.js e-commerce site to discover that canonical tags differ between server HTML and JS-rendered output, LCP exceeds 2.5s on mobile, and robots.txt accidentally blocks the XML sitemap. ## Quick Start Run a technical SEO audit on https://example.com and give me the category scores and prioritized fix list.
