SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a systematic audit and optimization plan to surface technical SEO blockers, indexation problems, on-page weaknesses, and content quality gaps that prevent pages from ranking and being discovered by search engines.

Core Features & Use Cases

  • Crawlability & Indexation Checks: Validate robots.txt, sitemap.xml, canonical tags, noindex usage, and identify SPA routes that hide content from crawlers.
  • Technical Foundations: Assess Core Web Vitals, TTFB, image and font delivery, HTTPS/HSTS, and shared SSR shell issues that affect every page.
  • On-Page & Content Optimization: Review title tags, meta descriptions, heading structure, keyword targeting, internal linking, and content E-E-A-T signals.
  • Structured Data & Social Metadata: Detect missing or poorly implemented JSON-LD schemas, og/twitter meta tags, and recommend site-wide vs per-page fixes.
  • Use Case: Run a prioritized audit for a marketing site or hybrid SPA/SSR app to produce a step-by-step remediation plan and a list of quick wins for immediate impact.

Quick Start

Curl the homepage and a representative public page to confirm server-rendered HTML or SPA fallback, check robots.txt and sitemap.xml responses, and generate a prioritized remediation list for indexation and Core Web Vitals.

Frequently Asked Questions about seo-auditor

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

FAQPage Schema
How do I audit my website for technical SEO issues and Core Web Vitals?▼

To audit technical SEO and Core Web Vitals, validate robots.txt and sitemap.xml responses, check canonical tags, and assess TTFB against performance targets. The process produces a prioritized remediation list for immediate search visibility improvements.

Why does my SPA route hide content from crawlers and how do I fix indexation?▼

SPA routes hide content from crawlers when client-side rendering prevents bots from reading HTML. Fix indexation by curling rendered HTML to verify SSR fallback, checking shared shells for site-wide metadata, and validating noindex usage.

How do I check structured data and JSON-LD schema validation on my site?▼

Check structured data and JSON-LD schema validation by examining the SSR shared shell for missing or poorly implemented schemas. Detect site-wide versus per-page schema gaps and recommend targeted fixes to ensure proper rich snippet eligibility.

Can I run an on-page SEO audit for a SaaS landing page or e-commerce product page?▼

Yes, you can run an on-page SEO audit for SaaS landing pages and e-commerce product pages. The audit reviews title tags, meta descriptions, heading structure, internal linking, and content E-E-A-T signals to surface ranking weaknesses.

What is the best way to find missing open graph and social meta tags in an SSR app?▼

The best way to find missing open graph and social meta tags in an SSR app is to examine the shared server-rendered shell. This validates site-wide og/twitter meta tags and recommends fixes for consistent social sharing across all routes.

When should I not use a technical SEO audit for my marketing site?▼

You should not run a technical SEO audit if your site lacks public pages or if HTTP-level verification of robots.txt and sitemap.xml is blocked. The audit requires accessible public URLs and server-rendered HTML to evaluate crawlability effectively.
