SYSTEM DOCUMENTATION & REQUIREMENTS

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, and finding them manually across an entire site is slow and error-prone. ## Core Features & Use Cases - Nine-Category Audit: Evaluates crawlability, indexability, security, URL structure, mobile optimization, Core Web Vitals, structured data, JavaScript rendering, and IndexNow support. - AI Crawler Management: Checks robots.txt rules for AI crawlers such as GPTBot, ClaudeBot, PerplexityBot, and Google-Extended, with guidance on selective blocking. - Prioritized Output: Produces a scored report (0-100) with a category breakdown table and issues grouped into critical, high, medium, and low priority fix windows. - Use Case: Run an audit on a newly launched Next.js site to confirm robots.txt allows Googlebot, canonical tags match between server HTML and JS-rendered output, and LCP stays under 2.5 seconds before submitting to search engines. ## Quick Start Run a technical SEO audit on https://example.com and report the score 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 checks nine categories: robots.txt, sitemaps, canonical tags, HTTPS and security headers, URL structure, mobile readiness, Core Web Vitals, structured data, and JavaScript rendering. Results include a score out of 100 and prioritized fixes.

What are good Core Web Vitals scores for SEO?▼

Target LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1, measured at the 75th percentile of real user data. INP replaced FID in March 2024, so FID should no longer be referenced.

Does blocking GPTBot in robots.txt stop ChatGPT from citing my site?▼

No. Blocking GPTBot prevents OpenAI model training, but ChatGPT can still cite your content through real-time browsing via the ChatGPT-User crawler. Similarly, blocking Google-Extended affects Gemini training but not Google Search indexing.

Can Google index content rendered only by JavaScript?▼

Google can render JavaScript, but with caveats: it does not render JS on non-200 status pages, may honor a noindex from raw HTML even if JS removes it, and may pick either canonical if server and JS versions differ. Serve critical SEO elements in the initial HTML.

What happens if the audited site has no robots.txt file?▼

The audit notes that no robots.txt was detected at the root domain and recommends creating one with appropriate directives, then continues evaluating the remaining eight categories.
