Hreflang Checker

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.
