  Effortless Validation: ✅ With a single click, scan any page for complete hreflang tag information, including language codes, region codes, return links, canonical consistency, and self-referencing tags.
  
  Error-Proof Targeting: 🌏 Identify missing, incorrect, or mismatched hreflang tags that could harm your global search ranking. Catches invalid language codes like "eng" instead of "en" and suggests the correct ISO 639-1 code.

  Canonical Consistency: 🔗 Flags pages where the canonical URL conflicts with hreflang tags, a common issue that sends mixed signals to search engines.
  
  SPA Compatible: ⚡ Works with JavaScript-rendered hreflang tags on single-page applications, not just static HTML.

  Supercharge your international SEO with instant hreflang checks. Built by SEO experts who fix hreflang for a living.
  
  Hreflang Checker analyzes any webpage's hreflang tags in one click, so you catch the errors that cost you global rankings before Google does.
  
  ✅ Complete Validation in One Click
  Scan any page for language codes, region codes, return links, canonical consistency, self-referencing tags, and x-default coverage.
  
  🔁 Duplicate & Conflict Detection
  Spots duplicate hreflang values and conflicting tags that point the same language at different URLs. Search engines pick one arbitrarily; you should pick it on purpose.
  
  🌏 Error-Proof Targeting
  Catches invalid language and region codes with smart suggestions: "eng" becomes "en", "en-UK" becomes "en-GB". Validates against ISO 639-1 and ISO 3166-1, including script codes like zh-Hans.
  
  🔀 Smart Redirect Detection
  Distinguishes harmless redirects (http to https, www normalization) from geo-IP redirects that skew results. You get warnings, not false failures.
  
  🔗 Canonical Consistency
  Flags pages where the canonical URL conflicts with hreflang tags, a common issue that sends mixed signals to search engines.
  
  ⚙️ SPA Compatible
  Works with JavaScript-rendered hreflang tags on single-page applications, not just static HTML.
  
  ⚡ Blazing Fast
  Checks each unique URL only once, even on pages with 40+ regional variants. Tests show validation over 450% faster than other online tools.
  
  🔒 Private & Lightweight
  No account, no tracking, no data collection. Everything runs in your browser.
  
  Whether you manage one multilingual site or a portfolio of international clients, install Hreflang Checker now and fix hreflang issues before they cost you rankings.
