Technical SEO Site Audit

seo

Technical SEO Site Audit is a Claude Code skill that checks a website across nine groups: crawlability, indexability, security, URL structure, mobile, Core Web Vitals, structured data, JavaScript rendering and the IndexNow protocol (used by Bing and Yandex). Use it before a launch, when pages do not get indexed, or when the site loads slowly. It reviews robots.txt, the sitemap, noindex, canonical tags, duplicates, redirects, crawl budget, HTTPS and security headers, LCP, INP and CLS, mobile and desktop content parity, and how much content depends on JavaScript in React, Vue or Angular sites. It covers AI crawler rules in robots.txt (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) and whether pages work for AI agents, including the accessibility tree. With Google API credentials configured it pulls real PageSpeed, CrUX and Search Console data. Output is a technical score out of 100, a category table and issues ranked by urgency.
