hreflang-check

Audit hreflang implementation from supplied HTML, sitemap XML, or SEO-tool exports (it does not crawl sites) — running seven checks: self-referential tags, bidirectional pairs, valid ISO 639-1/3166-1 codes, x-default, duplicates, absolute URLs, and URL consistency — producing a 0-100 score, a language coverage matrix, and corrected code snippets per issue. Triggers on "/digital-marketing-pro:hreflang-check", "audit our hreflang tags", "why is Google serving the wrong language version", "check x-default configuration", "validate our international SEO tags". Compares findings against the brand's configured languages in profile.json to flag markets with no hreflang coverage.
