A suite of technical SEO tools — each runs an instant check on your page, no signup. Try one below, then crawl your whole site against 80+ checks for free.
Instant, free, no account needed — homepage checked on the spot.
Make sure search engines can find, crawl and index your pages.
The full crawl-based audit: indexability, canonicals, hreflang, schema, sitemaps and redirects across every page.
Find pages Google can't index: noindex tags, robots.txt blocks, canonical conflicts and crawl issues.
Locate and validate your XML sitemap — structure, URL count, HTTPS consistency and live status.
Check rel=canonical tags: self-referencing, resolving to live 200 URLs, no canonical-to-redirect.
The page-level signals that control how you appear in search and on social.
Title, meta description, canonical, viewport and Open Graph tags — present, sized right, correct.
Find broken internal and outbound links, redirect chains and broken redirects, with their source pages.
Validate reciprocal hreflang, self-references and language codes for international sites.
Speed is a ranking factor and what users feel first.
Each instant check looks at one page. The full Kalenux SEO Audit crawls your entire site against 80+ technical checks plus PageSpeed, tracks your health score over time, and exports everything — built by a team that runs 10+ production sites in 15+ languages on the exact same engine.
