Diagnose Seo
The diagnose-seo skill provides a structured diagnostic framework for identifying and troubleshooting technical SEO problems, organized across four sequential layers: crawlability, indexability, renderability, and signals. It's designed for SEO professionals, developers, and site owners who need to systematically diagnose why pages aren't being indexed, fix crawl issues, resolve canonicalization errors, or troubleshoot robots.txt and sitemap problems. The skill solves the problem of scattered, non-systematic SEO troubleshooting by offering a layered approach that checks each dependency in order, starting with whether search engines can access pages before diagnosing indexation and rendering issues.

Diagnose SEO
Structured diagnostic framework for crawl issues, canonicalization errors, indexation problems, and rendering failures.
Diagnostic Approach
Technical SEO problems fall into four categories. Diagnose in this order — each layer depends on the previous one working correctly:
- Crawlability — Can search engines find and access the pages?
- Indexability — Are the pages allowed to be indexed?
- Renderability — Can search engines see the full content?
- Signals — Are the right signals (titles, structured data, links) in place?
Layer 1: Crawlability
Check these in order:
robots.txt
- Fetch
[domain]/robots.txtand review the rules - Look for overly broad
Disallowrules blocking important paths - Verify
Sitemap:directive points to the correct sitemap URL - Check for different rules per user-agent (Googlebot vs others)
Common mistakes:
Disallow: /blocking the entire site (often left from staging)- Blocking CSS/JS files that Googlebot needs for rendering
- Blocking API or AJAX endpoints that load dynamic content
- Staging robots.txt accidentally deployed to production
