This audits technical SEO across nine categories including crawlability, indexability, Core Web Vitals, and JavaScript rendering. It checks robots.txt (including AI crawler management for GPTBot, ClaudeBot, and Google-Extended), validates canonical tags, tests security headers, and scores mobile optimization. The skill incorporates December 2025 JavaScript SEO guidance on canonical conflicts and recent updates like INP replacing FID. Output is a scored breakdown with prioritized fix lists. It's current with real-world crawler tokens and protocol changes, though you'll get the most from it if you have DataForSEO or Google API access for live PageSpeed and CrUX data rather than just static checks.
