Hreflang and international SEO audit, validation, and generation
by agricidanielFree
Description
seo-hreflang is a Claude SEO skill for international SEO. It audits existing hreflang implementations on multi-language and multi-region sites, validates language and region codes, and generates correct hreflang tags where a site needs them. It works with the three ways hreflang can be delivered: in HTML, in HTTP headers, and in XML sitemaps. The audit centers on two checks. The first is self-referencing tags: every page must include an hreflang tag that points to itself, and that URL must exactly match the page's canonical URL, because a missing self-reference can make Google ignore the whole set. The second is return tags: if page A points to page B, page B must point back to A. Every relationship has to be bidirectional, and every language version should reference all the others in a full mesh. A missing return tag invalidates the signal for both pages. The skill is installed with npx skills from the claude-seo repository, and its security audits show Gen Agent Trust Hub, Socket and Snyk all passing.…
