Thirty checks in six groups: indexability (canonical, meta robots, X-Robots-Tag), head and metadata (title, meta description, hreflang, lang, viewport, charset, Open Graph), content (H1, heading hierarchy, word count, image alt text, image formats, internal vs external links), network and security (HTTPS, HTTP to HTTPS redirect, status code, response time, security headers, mixed content), site-wide files (robots.txt presence, crawl blocking, sitemap declaration, AI crawler access) and detected technology (analytics, structured data). ### Does it use AI to analyze my site? No. Every check is deterministic HTML parsing, which is why a full audit comes back in under a second and why two runs over the same page always agree. There is nothing generative here — the tool measures your markup and reports what it measured. ### How is the score calculated? A pass counts fully, a warning counts as half, a failure counts as zero, and informational checks are excluded so extra context can never move your number. The result is a 0-100 score and a letter grade: S for 90 and above, then A, B, C and D. ### Which page does it audit? Your homepage, plus your robots.txt and a quick check of whether the http:// version of your site redirects to https://. If you enter a full URL we use its domain, so the audit always reflects your site's front door. ### Is my data stored? Audit results are cached for a day so a repeat check is instant, and nothing else is kept. There is no sign-up, no email required, and we never store page content beyond that cache. ### Will this catch everything wrong with my SEO? No — it catches on-page technical issues on the page it fetches. It does not crawl your whole site, judge your content quality, or analyze your backlinks. Treat it as the fast first pass that tells you whether anything is badly broken. ## Related tools - [Sitemap Validator](https://skribra.com/tools/sitemap-validator): Validate your XML sitemap, count URLs and follow nested sitemap indexes. - [CMS Detector](https://skribra.com/tools/cms-detector): Find out which CMS, builder or framework any website is running on. - [Meta Description Checker](https://skribra.com/tools/meta-description-checker): Check meta description length and preview how it appears in search. - [Heading Structure Checker](https://skribra.com/tools/heading-structure-checker): Analyze your H1-H6 hierarchy and find structural problems. ## Machine-readable index - HTML version of this page: https://skribra.com/tools/technical-seo-audit - Site index for agents: https://skribra.com/llms.txt - Sitemap: https://skribra.com/sitemap.xml - Public REST API: https://skribra.com/api/v1 - OpenAPI specification: https://skribra.com/openapi.json
