What the SEO Technical skill actually is?

A nine-category deep technical inspection

The seo-technical skill audits the nine foundational technical SEO categories that determine whether Google can find, crawl, render, and index your pages. It goes deeper than the general audit on technical signals, scoring each category individually with Critical-to-Low severity tiers.

A notable 2025 addition is AI crawler management: the skill audits robots.txt for GPTBot, ClaudeBot, PerplexityBot, ByteDance, and Google-Extended. It distinguishes the critical difference: blocking Google-Extended prevents Gemini training use but does NOT affect Google Search indexing.

Output is a technical score (0-100) with category breakdowns, status ratings, and prioritized issue lists. Every finding maps to a specific implementation fix.

When it Triggers?

Triggers on /seo technical <url>, or phrases like 'technical SEO audit', 'check crawlability', 'indexing issues', 'Core Web Vitals audit', or 'technical check'. Pass a domain and it starts from the root.

For live Core Web Vitals data (CrUX field metrics), pair with /seo google crux. The technical skill assesses HTML signals; CrUX provides real-user measurement data from the Chrome dataset.

What it audits

From robots.txt to IndexNow

01

Crawl and index health

Validates robots.txt directives, sitemap presence and format, canonical accuracy, duplicate content patterns, pagination handling, and hreflang consistency across language variants.

02

Performance and security

Checks HTTPS enforcement, security headers (CSP, HSTS, X-Frame-Options), mobile responsiveness, touch target sizing, Core Web Vitals signals, and render-blocking resources.

03

JavaScript rendering

Detects CSR vs SSR, compares canonical and noindex tags between raw HTML and JavaScript-rendered output, and flags elements that may face delayed processing by Googlebot.

04

AI crawler management

Audits robots.txt for AI crawler directives across OpenAI, Anthropic, Perplexity, ByteDance, and Google. Flags the Google-Extended distinction: training block vs search block.
