This Skill prevents international SEO failures by detecting incorrect hreflang implementations, including invalid language/region codes, broken bidirectional return relationships, missing x-default, and canonical/protocol mismatches that cause search engines to ignore hreflang sets.
Use the hreflang skill to audit a site’s international language versions at https://example.com and produce a corrected hreflang implementation plan.

Hreflang code correctness requires validating language codes against ISO 639-1 and region qualifiers against ISO 3166-1 Alpha-2 formatting rules. This ensures search engines properly interpret multi-language and multi-region page targeting without ignoring your hreflang sets.
Hreflang implementation supports XML sitemap xhtml:link entries, HTML link tags, and HTTP header Link alternates. Generating implementation-ready output across these three formats ensures comprehensive international SEO coverage for multi-language websites.
Search engines ignore hreflang tags when implementations contain invalid language/region codes, broken bidirectional return relationships, missing x-default, or canonical/protocol mismatches. Auditing these specific errors ensures search engines properly process your multi-region hreflang sets.
Generating hreflang annotations requires producing implementation-ready output for HTML link tags, HTTP header Link values, and XML sitemap xhtml:link structures. This guarantees protocol consistency and ISO-compliant language/region codes across all page versions.
X-default hreflang and canonical alignment are required to prevent international SEO failures. Scanning for x-default requirements and canonical URL alignment ensures search engines correctly route users to appropriate language and regional page versions.
