Features — What We Analyze
SelfSeoAudit checks over 100 SEO checkpoints and delivers a prioritized action plan. Each category targets a distinct set of ranking factors. Learn more in our full documentation.
Technical SEO Checks
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.
