SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? It identifies why a website is not ranking or losing organic traffic by systematically auditing crawlability, indexation, site speed, on-page optimization, and content quality, then delivering a prioritized action plan. ## Core Features & Use Cases - Technical SEO Audit: Checks robots.txt, XML sitemaps, canonicalization, Core Web Vitals, HTTPS, mobile-friendliness, and international SEO (hreflang, locale sitemaps, multilingual canonicals). - On-Page & Content Review: Evaluates title tags, meta descriptions, heading structure, internal linking, keyword targeting, and E-E-A-T signals, with site-type-specific frameworks for SaaS, e-commerce, blogs, multilingual, and local businesses. - Use Case: After a WordPress-to-Next.js migration causes a 40% traffic drop, run an audit to check redirect mappings, canonical tags, and sitemap updates, then receive a prioritized recovery plan. ## Quick Start Audit the SEO of my website at https://example.com and tell me why my organic traffic dropped after our recent site migration.

Frequently Asked Questions about seo-audit

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

FAQPage Schema
How do I audit my website for SEO issues?▼

Follow a priority order: crawlability and indexation first, then technical foundations like Core Web Vitals, then on-page optimization, content quality, and authority. Check robots.txt, XML sitemaps, canonical tags, title tags, and heading structure, then compile findings into a prioritized action plan.

Why did my organic traffic drop after a site migration?▼

Migration traffic drops usually stem from missing 301 redirect mappings, incorrect canonical tags, robots.txt blocking crawlers, or outdated XML sitemaps. Check Search Console coverage reports for indexation errors and verify redirect chains are clean.

Can web_fetch or curl detect schema markup on a page?▼

No. Many CMS plugins inject JSON-LD via client-side JavaScript, which static fetch tools strip out. Use a browser rendering tool, Google Rich Results Test, or a Screaming Frog crawl export to accurately detect structured data.

What are common hreflang mistakes on multilingual sites?▼

Common errors include missing self-referencing entries, non-reciprocal return tags, invalid codes like en-UK instead of en-GB, and canonical URLs conflicting with the hreflang set. Any of these can cause Google to ignore the annotations entirely.

Does page speed affect SEO rankings?▼

Yes. Core Web Vitals are ranking signals: LCP should be under 2.5 seconds, INP under 200ms, and CLS under 0.1. Diagnose issues with PageSpeed Insights, WebPageTest, and the Search Console Core Web Vitals report.

When should I use a different skill instead of an SEO audit?▼

Use schema-markup for implementing structured data like FAQ schema, programmatic-seo for building keyword-targeted pages at scale, and ai-seo for optimizing content for AI search engines. The audit skill is for diagnosis, not implementation.
