SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Performs a comprehensive technical SEO audit across critical categories to identify crawl, index, security, and structure issues that block search visibility.

Core Features & Use Cases

  • Indexability and structure: canonicalization, duplicate content, parameter handling, pagination, hreflang, and index bloat.
  • Security and mobile readiness: HTTPS enforcement, security headers, HSTS, X-Frame-Options, and mobile-first considerations.
  • Core Web Vitals and performance: LCP, INP, CLS targets, and data sources for real-world measurements.
  • Structured data and JavaScript rendering: validate JSON-LD, microdata, and SSR/CSR implications; ensure critical data is available to Google.
  • IndexNow readiness: check for IndexNow support to speed up indexing on non-Google engines.
  • Use case examples: an ecommerce site needing faster product indexing and better crawl coverage.

FAQPage Schema
How do I perform a technical SEO audit to identify crawlability and indexability issues?▼

A technical SEO audit checks robots.txt validity, sitemap references, canonicalization, and hreflang tags to resolve crawl blocks and index bloat. This process evaluates URL structure and duplicate content to deliver prioritized fix recommendations.

What is the best way to check Core Web Vitals and structured data for JavaScript rendering?▼

Checking Core Web Vitals involves measuring LCP, INP, and CLS targets against real-world data sources. Structured data validation examines JSON-LD and microdata alongside SSR and CSR JavaScript rendering behavior to ensure critical page data is visible to search engines.

Can I use IndexNow protocol to speed up indexing on non-Google search engines?▼

Yes, you can check IndexNow readiness to speed up indexing on non-Google engines. An audit verifies if your site supports the IndexNow protocol, allowing you to instantly notify participating search engines about new or updated content URLs.

Does a technical SEO audit include security and mobile-first readiness checks?▼

Yes, a technical SEO audit includes security and mobile-first readiness checks. It enforces HTTPS, validates security headers like HSTS and X-Frame-Options, and evaluates mobile-first considerations to ensure compliance with modern search engine requirements.

How do I validate hreflang tags and canonicalization for a large ecommerce site?▼

Validating hreflang tags and canonicalization for large sites requires analyzing index bloat, pagination, and parameter handling. The audit detects duplicate content and incorrect canonical tags, guiding on-page optimizations to improve crawl budget and coverage.

What are the limitations of automated technical SEO audits for JavaScript rendering?▼

Automated technical SEO audits for JavaScript rendering may struggle with dynamic CSR content that requires execution to load critical data. While they validate SSR behavior and JSON-LD schema, complex JavaScript rendering needs can still block search visibility if not fixed.
