# Technical SEO Checker This skill performs comprehensive technical SEO audits to identify issues that may prevent search engines from properly crawling, indexing, and ranking your site. ## What This Skill Does Audits crawlability, indexability, Core Web Vitals, mobile-friendliness, HTTPS/security, structured data, URL structure, and international SEO with scored results and a prioritized fix roadmap. ## Quick Start Start with one of these prompts, then finish with the standard handoff summary from [Skill Contract](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/references/skill-contract.md). ### Full Technical Audit ``` Perform a technical SEO audit for [URL/domain] ``` ### Specific Issue Check ``` Check Core Web Vitals for [URL] ``` ``` Audit crawlability and indexability for [domain] ``` ### Pre-Migration Audit ``` Technical SEO checklist for migrating [old domain] to [new domain] ``` ``` Pre-migration audit: WordPress to Next.js headless ``` The migration flow has 6 stages (baseline snapshot, risk map, redirect map, staging QA, cutover checklist, T+1/T+7/T+30 diff). See [references/pre-migration-playbook.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/optimize/technical-seo-checker/references/pre-migration-playbook.md) for the full workflow and red-flag patterns. ### LLM Crawler Handling (GPTBot / ClaudeBot / PerplexityBot) ``` Audit how my site handles AI crawlers — I want to allow retrieval but block training ``` As of 2026, robots.txt must make explicit decisions about AI engines. See [references/llm-crawler-handling.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/optimize/technical-seo-checker/references/llm-crawler-handling.md) for the bot inventory, three stance patterns (default-open, default-closed, split), robots.txt templates, and the Cloudflare edge-override gotcha. ### Site-Wide / Bulk Audit (5+ URLs) For e-commerce and large sites (e.g., "40 of 50 products not indexed"), switch to bulk mode — sample per URL pattern, report pattern-level findings, deliver portfolio priority instead of per-URL output: ``` Bulk audit: 50 product pages on example.com, 40 not indexed ``` ``` Audit all URLs in https://example.com/sitemap.xml ``` See [references/bulk-audit-playbook.md](https://github.com/aaron-he-zhu/s
