SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

hreflang-check identifies and corrects faulty hreflang implementation so search engines can correctly route multilingual and multi-regional users to the right language and regional page.

Core Features & Use Cases

  • Hreflang correctness audit: Detects missing self-referential tags, bidirectional reference mismatches, duplicate language-region codes, missing x-default, invalid language-region codes, non-absolute URLs, and URL consistency problems (protocol, www/non-www, trailing slash).
  • Cross-reference validation: Builds a page-to-page hreflang map and checks that alternate pages reference each other correctly for every language-region pairing.
  • Actionable fixes: Produces a prioritized issue list and copy-ready corrected hreflang code snippets grouped by page and by systemic issue type.
  • Coverage and compliance context: Compares hreflang languages to the active brand’s configured language set and flags gaps or potential stale entries.

Quick Start

Run hreflang-check for your multilingual site by providing your hreflang data (HTML <link> tags, sitemap, headers, or exported tool data) and ask it to generate a corrected hreflang audit with implementation-ready snippets.
