SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Technical SEO issues like broken robots.txt rules, slow Core Web Vitals, missing security headers, and JavaScript rendering problems silently block search engines from indexing a site. This Skill runs a structured audit across nine categories and produces a prioritized fix list instead of a raw pile of checks. ## Core Features & Use Cases - Nine-category audit: Covers crawlability, indexability, security, URL structure, mobile, Core Web Vitals (LCP, INP, CLS), structured data, JavaScript rendering, and IndexNow, each scored pass/warn/fail. - AI crawler and agent readiness: Audits robots.txt rules for AI crawlers (GPTBot, ClaudeBot, Google-Extended) and checks agent-friendly page criteria via accessibility-tree analysis and the Lighthouse Agentic Browsing category. - Real data integration: Optionally pulls PageSpeed Insights, CrUX field data, Search Console indexation status, and DataForSEO on-page analysis through the bundled claude-seo CLI. - Use Case: A site owner notices organic traffic dropping. Run the audit against the homepage to discover that a canonical tag injected by JavaScript conflicts with the server-rendered one, then get a prioritized Critical/High/Medium/Low fix plan. ## Quick Start Run a technical SEO audit on https://example.com and report the category scores with prioritized fixes.

Frequently Asked Questions about seo-technical

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a technical SEO audit on my website?▼

Provide the target URL and the audit runs across nine categories: crawlability, indexability, security, URL structure, mobile, Core Web Vitals, structured data, JavaScript rendering, and IndexNow. Results include a 0-100 score and a prioritized fix list grouped by severity.

What Core Web Vitals thresholds does a technical SEO audit check?▼

The audit checks LCP at or below 2.5 seconds, INP at or below 200 milliseconds, and CLS at or below 0.1, evaluated at the 75th percentile of real user data. FID is no longer used; INP replaced it in March 2024.

How do I block AI crawlers like GPTBot with robots.txt?▼

Add a User-agent block for each crawler token, such as GPTBot, ClaudeBot, or Google-Extended, with Disallow: /. Blocking Google-Extended stops Gemini training use but does not affect Google Search indexing or AI Overviews.

Does the audit work with JavaScript-rendered sites like React or Vue?▼

Yes. It checks whether critical content, canonical tags, meta robots directives, and structured data appear in the initial server-rendered HTML versus being injected by JavaScript, and flags SPA rendering patterns that cause indexing issues.

Why is Core Web Vitals data unavailable for my site?▼

CrUX field data requires sufficient real-user traffic, so low-traffic sites often have no data. The audit falls back to Lighthouse lab data as a proxy and recommends re-testing after traffic grows.

Can the audit use real PageSpeed Insights or Search Console data?▼

Yes, if Google API credentials are configured, it runs pagespeed_check.py for PSI and CrUX field data, crux_history.py for 25-week trends, and gsc_inspect.py for per-URL indexation status. Without credentials it relies on lab-based checks.
