Technical SEO Checks

Technical SEO analysis icon — crawl errors, redirects, canonicals

Identify crawl errors, broken links, redirect chains, canonical tag issues, robots.txt problems, and XML sitemap coverage. Technical issues prevent search engines from properly indexing your site.

  • Crawl & Indexation — Broken links, redirect chains, noindex tags, and robots.txt directives.
  • Performance — Core Web Vitals (LCP, CLS, FID), page speed, and render-blocking resources.
  • Structured Data — Schema.org markup validation for rich results eligibility.

On-Page SEO and Content Analysis

On-page factors directly influence how search engines interpret and rank each page. Our tool checks title tags, meta descriptions, heading hierarchy, keyword placement, and image optimization.

  • Meta Tags — Title length, description uniqueness, Open Graph and Twitter Card presence.
  • Heading Structure — H1 uniqueness, H2/H3 hierarchy, keyword coverage in headings.
  • Image Alt Text — Missing or empty alt attributes on all images detected.
  • Content Quality — Thin content detection, duplicate content flags, readability scoring.

Security, Mobile and Accessibility

Google uses mobile-first indexing and considers security a ranking signal. We verify HTTPS configuration, mixed-content warnings, mobile viewport settings, and WCAG accessibility compliance.

  • Security & HTTPS — SSL certificate validity, mixed content warnings, security headers (HSTS, CSP).
  • Mobile Compatibility — Viewport meta tag, touch target sizes, responsive layout checks.
  • ARIA & Accessibility — Landmark roles, alt attributes, contrast issues, keyboard navigation.
