Hreflang International

description: >
  International / multilingual SEO audit focused on hreflang correctness. Detects
  and diagnoses the most common (and ranking-damaging) hreflang mistakes: missing
  or broken return tags, wrong language/region codes, missing x-default,
  self-referencing errors, conflicts between hreflang and canonical, and
  inconsistent signals across HTML head / HTTP headers / XML sitemap. Also reviews
  the broader international setup — URL structure (ccTLD vs subdirectory vs
  subdomain), language targeting, and geo signals. Use this skill whenever the
  user runs a multi-language or multi-region site and asks about hreflang,
  international SEO, multilingual SEO, the wrong-language page showing in search,
  duplicate-content across country versions, or "th/en page ranking in the wrong
  country". Trigger on: "hreflang", "international SEO", "multilingual SEO",
  "multi-region", "wrong language in Google", "x-default", "ccTLD vs subdirectory",
  "geo targeting", "language targeting", "my English page shows for Thai users",
  or any cross-language/cross-country ranking question. For full-site audits use
  /seo-analysis; for a single URL use /seo-page.
