The same engine that audits our portfolio
Most "free SEO checkers" run a dozen surface checks on one page. We crawl your entire site and go deep.
Broken internal & outbound links, redirect chains, broken redirects, orphan pages, links to non-indexable URLs.
Noindex pages, canonical errors, canonical-to-redirect, pages that became non-indexable, non-canonical URLs in your sitemap.
Missing / duplicate / too-long / too-short titles and meta descriptions, Open Graph & Twitter card tags.
Hreflang correctness — missing reciprocal tags, language mismatches, broken hreflang, missing self-reference, html lang.
JSON-LD schema errors and Google-style missing-field warnings that block rich results.
Thin / empty pages, low text-to-HTML ratio, missing or filename image alt text, placeholder text, deep pages.
Slow pages, uncompressed / unminified CSS & JS, mixed content, plus full PageSpeed & Core Web Vitals audits.
Missing robots.txt, blocked sitemaps, sitemap too large, missing lastmod, pages missing from the sitemap.
Enter your URL and verify ownership via DNS, a meta tag, or a file.
We crawl up to thousands of pages and run every check, then compute a health score out of 100.
Work the prioritized issue list, re-run, and watch your score climb. See exactly what you fixed and what's new.
Run a full technical SEO audit on your website.
Crawl-based checks across indexability, canonicals and more.

Validate international SEO and hreflang implementation.
An SEO audit crawls your website and checks it against technical SEO best practices — broken links, redirects, canonical tags, meta data, hreflang, structured data, sitemaps, page speed and more — then reports what's hurting your rankings so you can fix it.
You start free with 1 credit on signup. When you need more, buy a one-time credit pack — Starter (50 credits, $9), Growth (150 credits, $19), or Pro (500 credits, $49). No subscription, and credits never expire. See the pricing page.
Those are broad suites focused on keywords and backlinks at $100+/month. Kalenux SEO Audit focuses on technical site health and PageSpeed — what's actually broken and whether you fixed it.
Yes. To crawl a site you confirm ownership with a DNS TXT record, a meta tag, or an uploaded file, so the software only audits sites you control.
Checkout is handled securely by Creem, our Merchant of Record. Unused credits are fully refundable within 14 days; once you have run an audit, that purchase is final. See our refund policy and terms.
