SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you identify technical SEO failures that prevent pages from being crawled and indexed, such as broken canonical signals, incorrect robots directives, missing sitemap references, and problematic URL patterns.

Core Features & Use Cases

  • Canonical and duplication control: Detects missing, invalid, duplicate, or cross-domain canonical tags to reduce duplicate-content risks.
  • Robots and indexability checks: Flags noindex/nofollow configurations and verifies whether pages appear indexable based on meta directives.
  • Sitemap and URL structure auditing: Checks for sitemap references and evaluates URL formatting for crawl-friendly consistency.
  • Operational use cases: Use during SEO troubleshooting for staging vs production, Next.js rendered HTML verification, and fixing crawl/index issues before publishing.

Quick Start

Ask an AI coding agent to run a technical SEO audit of the provided page HTML and report each check as PASS, WARN, or FAIL with specific fix guidance.

FAQPage Schema
How do I check if a page has crawlability and indexability issues?

To check crawlability and indexability issues, audit canonical tags, robots directives, sitemap references, and URL structure to identify blocked pages, incorrect noindex configurations, and duplicate-content risks using deterministic PASS, WARN, or FAIL outcomes.

What does a canonical tag do for duplicate content risk?

Canonical tags control duplicate content risk by specifying the preferred URL version. Auditing canonical correctness detects missing, invalid, duplicate, or cross-domain canonical tags, reducing duplicate-content issues during troubleshooting and pre-launch reviews.

How do I audit robots directives and noindex configurations?

Audit robots directives by flagging noindex and nofollow configurations in the HTML meta tags. This verifies whether pages are indexable based on meta patterns, identifying pages blocked from indexing or difficult to crawl before publishing.

Can I use a technical SEO audit for Next.js rendered HTML?

Yes, technical SEO audits work for Next.js rendered HTML by verifying crawlability and indexability signals in the rendered output. This supports troubleshooting staging versus production environments and fixing crawl or index issues before publishing.

Why is my page not showing up in search results despite being live?

Your page may not appear due to technical SEO failures like incorrect robots directives, broken canonical signals, or missing sitemap references. Auditing these crawlability and indexability signals identifies whether pages are blocked or difficult to index.

What is the best way to verify URL structure for crawl-friendly consistency?

The best way to verify URL structure for crawl-friendly consistency is to audit URL formatting against indexability checklist criteria. This evaluates URL patterns for crawl-friendly consistency and identifies problematic URL structures that hinder search engine crawling.
