Quickly check hreflang tags on webpages for SEO. Validate return links, language codes, canonical URLs, and detect geo-IP redirects.

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.
