Аудит и валидация hreflang-тегов

★ 8.1 · seo

seo-hreflang is a Claude Code skill that audits, validates, and generates hreflang tags for international SEO. It checks for self-referencing tags, bidirectional return tags across all language versions, ISO 639-1 language codes, ISO 3166-1 Alpha-2 region codes, canonical URL alignment, and HTTP/HTTPS consistency. All three implementation methods are supported — HTML link tags, HTTP headers, and XML sitemaps — including cross-domain setups across different TLDs. The skill catches common mistakes such as `eng` instead of `en`, `en-uk` instead of `en-GB`, missing x-default, or hreflang placed on non-canonical URLs, and rates each issue by severity. It's built for teams managing multi-language or multi-region sites who need to ensure Google correctly maps each page variant to the right audience.
