seo-hreflang

The seo-hreflang skill is designed to assist webmasters, SEO specialists, and digital marketers in managing international SEO through proper hreflang implementation. Hreflang tags are essential for multi-language and multi-region websites to indicate to search engines the linguistic and regional targeting of each page. Misconfigured hreflang tags can lead to indexing issues, duplicate content problems, and lost traffic due to search engines not correctly serving the intended language version to users. This skill automates the auditing, validation, and generation of hreflang tags to ensure compliance with standards and best practices.

Key features of seo-hreflang include comprehensive validation checks such as verifying self-referencing tags, bidirectional return tags between pages, x-default fallback tags, language and region code correctness, canonical URL alignment, protocol consistency, and cross-domain support. It also identifies common mistakes, ranks them by severity, and provides guidance for fixing them. The skill supports multiple implementation methods including HTML link tags, HTTP headers, and XML sitemaps, making it flexible for different website architectures. Users can detect errors like missing self-references, invalid ISO language codes, incorrect region codes, or HTTPS/HTTP mismatches, ensuring that all language versions are properly interconnected and recognized by search engines.

This skill is particularly useful for global websites managing content in multiple languages or targeting multiple regions, as well as agencies performing international SEO audits. It helps teams maintain correct hreflang implementation during website launches, migrations, or expansions into new markets. By using seo-hreflang, users can enhance search engine visibility for localized content, reduce indexing issues, and improve user experience for international audiences.
