SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Websites lose organic traffic due to hidden crawlability, indexation, speed, and content issues that are hard to diagnose without a structured framework. This Skill turns vague concerns like "why am I not ranking" or "my traffic dropped" into a systematic SEO audit with prioritized, actionable fixes. ## Core Features & Use Cases - Full Audit Framework: Covers crawlability, indexation, Core Web Vitals, mobile-friendliness, HTTPS, URL structure, title tags, meta descriptions, headings, internal linking, and E-E-A-T content quality in a strict priority order. - Site-Type Playbooks: Includes tailored diagnostic checklists for SaaS, e-commerce, blogs, multilingual sites, and local businesses, plus a dedicated international SEO reference covering hreflang, canonicalization, and locale sitemaps. - Structured Reporting: Produces an executive summary, findings with impact/evidence/fix/priority, and a prioritized action plan. - Use Case: After a WordPress-to-Next.js migration causes a 40% traffic drop, use this Skill to check redirect mappings, canonicals, sitemaps, and indexation, then get a recovery plan ordered by criticality. ## Quick Start Ask the assistant to run an SEO audit on your website URL and explain why your organic traffic dropped.

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?

Run a structured SEO audit covering crawlability, indexation, site speed, on-page elements, and content quality in that priority order. This Skill checks robots.txt, XML sitemaps, canonicals, title tags, headings, and internal links, then outputs a prioritized action plan.

Why did my organic traffic drop after a site migration?

Traffic drops after migration usually come from missing 301 redirects, broken canonical tags, blocked crawlers, or outdated sitemaps. The audit checks redirect chains, soft 404s, and Search Console coverage, then provides a prioritized recovery plan.

What are good Core Web Vitals scores for SEO?

Good Core Web Vitals thresholds are LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1. Page speed is a ranking factor, so pages loading in 5-6 seconds need fixes to server response, images, JavaScript, caching, and CDN usage.

Can web_fetch detect schema markup on my pages?

No, web_fetch and curl cannot reliably detect schema markup because CMS plugins often inject JSON-LD via client-side JavaScript. Use a browser rendering tool, Google Rich Results Test, or a Screaming Frog export to accurately verify structured data.

How do I fix hreflang errors on a multilingual site?

Fix hreflang by ensuring every page has a self-referencing entry, reciprocal return links, valid ISO codes, and an x-default fallback. Each locale must self-canonical, and the canonical URL must appear in the hreflang set or all annotations are ignored.

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

Use a dedicated schema skill when the task is implementing structured data such as FAQ or product markup. The SEO audit skill diagnoses issues and flags schema gaps but defers actual structured data implementation to the schema skill.
