About this free hreflang checker

Hreflang tells Google which language or regional version to show. Missing reciprocals or x-default causes wrong country rankings.

This tool lists hreflang alternates on a page so you can validate international SEO setup quickly.

What it checks

  • link rel=alternate hreflang entries in HTML
  • Presence of x-default where applicable
  • Count and targets of language/region pairs

Why it matters for SEO

  • Prevents cross-country cannibalization between .com, .co.uk, and translated paths.
  • Required for multi-language sites to avoid duplicate content confusion.
  • Supports correct SERP language badges.

How to use this tool

  1. Audit a representative page from each locale version.
  2. Ensure each URL references all alternates including itself (reciprocal).
  3. Add or fix x-default for global fallback where needed.

Common issues we help you catch

  • One-way hreflang (A points to B but B does not point to A)
  • Missing x-default on global sites
  • Hreflang pointing to redirects or 404s

Frequently asked questions

HTML hreflang vs sitemap hreflang?
Both are valid; many enterprise sites use sitemap for scale. HTML is fine for smaller multilingual setups if kept consistent.
