Auditoria, validação e geração de hreflang e SEO internacional — detecta erros comuns, valida códigos de idioma/região e gera a implementação correta. Use ao pedir 'hreflang', 'i18n SEO', 'SEO internacional', 'multi-language', 'multi-region' ou 'language tags'.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hreflang & International SEO Validate existing hreflang implementations or generate correct hreflang tags for multi-language and multi-region sites. Supports HTML, HTTP header, and XML sitemap implementations. ## Validation Checks ### 1. Self-Referencing Tags - Every page must include an hreflang tag pointing to itself - The self-referencing URL must exactly match the page's canonical URL - Missing self-referencing tags cause Google to ignore the entire hreflang set ### 2. Return Tags - If page A links to page B with hreflang, page B must link back to page A - Every hreflang relationship must be bidirectional (A→B and B→A) - Missing return tags invalidate the hreflang signal for both pages - Check all language versions reference each other (full mesh) ### 3. x-default Tag - Recommended when a selector/fallback URL exists: designates the fallback page for unmatched languages/regions - Typically points to the language selector page or English version - Only one x-default per set of alternates - Must also have return tags from all other language versions ### 4. Language Code Validation - Must use ISO 639-1 two-letter codes (e.g., `en`, `fr`, `de`, `ja`) …

How to install
mdr add joaoguirunas/team-os/seo-hreflang@sha256:c4817a33f33963e0The line at the top of this page pins the label v2.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
