Check your homepage instantly below — no signup. Then crawl every page for indexability, canonicals, hreflang, structured data, sitemaps and more. Find the technical issues holding your rankings back.
Instant, free, no account needed — homepage checked on the spot.
We separate indexable from non-indexable pages and check each correctly — so your report reflects what Google actually sees.
Noindex pages, canonical-to-redirect, canonical changes over time, and pages that became non-indexable.
Missing reciprocal hreflang, language mismatches, broken hreflang, missing self-reference, html lang.
JSON-LD schema errors plus Google-style missing-field warnings that block rich results.
Non-canonical URLs in your sitemap, pages missing from it, deep pages, too many links, orphan pages.
Redirect chains, broken redirects, HTTP→HTTPS issues, redirected pages with no incoming links.
Missing HSTS, mixed content, broken images and broken JavaScript references.

These are the issues that quietly cost rankings. Here's what each one means and how to fix it.
A stray noindex on a shared template, or a Disallow in robots.txt, can deindex a whole section silently. Grep your built output for noindex and make sure it only appears where you intend (thank-you pages, internal search). In Search Console, the Pages report tells you exactly what is indexed and why the rest isn't.
Every page should self-reference its canonical unless you deliberately point elsewhere. The common bug: a canonical that targets a redirect or a 404 — Google ignores those and picks its own URL. After any HTTP→HTTPS or trailing-slash change, re-check that every canonical resolves to a live 200 page.
Your sitemap is a list of "please index these." If it contains redirected, non-canonical, or 404 URLs, you send mixed signals and waste crawl budget. It should contain only canonical, indexable, 200-status URLs — and be declared in robots.txt.
Collapse redirect chains (A→B→C should be A→C) and fix redirects that land on a 404. Broken internal links waste crawl budget and leak authority. Watch for orphan pages — pages with zero internal links — which Google struggles to find and value.
Invalid JSON-LD doesn't just fail to help — it can throw errors in Search Console and block rich results. A frequent one is putting aggregateRating on an object type that doesn't support it. Validate every schema block.
Every hreflang annotation needs a reciprocal return tag and a self-reference, must not point at redirected URLs, and the html lang attribute should match. Hreflang is the single most error-prone area of technical SEO — we built a dedicated hreflang checker for it.
A technical SEO checker crawls your website and tests it against the technical best practices search engines rely on: indexability, canonical tags, hreflang, structured data, sitemaps, redirects, broken links and page speed. It reports what is broken so you can fix the issues that quietly hold rankings back.
Run a full crawl after any deploy that touches templates, redirects, canonicals or the sitemap, and at least monthly otherwise. Technical issues are usually introduced by a change, so auditing right after a release catches regressions early.
No. Search Console and PageSpeed Insights are free, and Screaming Frog's free tier crawls up to 500 URLs. For whole-site crawls without a monthly bill, Kalenux SEO Audit runs the full checklist plus PageSpeed for one-time credits ($9–49) that never expire.
It removes what stops pages from ranking — deindexed pages, broken canonicals, slow load, invalid schema. It doesn't invent demand, but it ensures the content you have can be crawled, indexed and ranked. It's the foundation the rest of SEO sits on.
