# Multilingual Launch

## Use this when

multilingual blog, write in multiple languages, international blog, multiple languages.

## Process

One topic, one source language (default the user's working language), and a comma-separated list of Google-compatible hreflang target codes. If 10 or more target languages are requested, stop before writing anything and ask for a reviewed batch of at most 9 — this is a scaled-content-abuse guardrail, not a technical limit.

Sequence: write the original post first (through the normal blog-write playbook, so template selection, sourced statistics, and schema priorities all still apply); translate it into every target language (can run in parallel per language); unless the user opted out, run cultural localization on every translation (also parallelizable); then generate the international SEO assets.

Assets to generate: hreflang `<link>` tags for every language including a self-reference and an `x-default` fallback (every href a fully-qualified absolute HTTPS URL, every relationship reciprocal); an equivalent hreflang sitemap fragment; a machine-readable hreflang map (JSON) for CMS integration listing every version's language, slug, URL, canonical, and whether it's the `x-default`; and localized Article/BlogPosting schema per version with `inLanguage` and a `translationOfWork` reference back to the source.

Report a delivery summary: the source file, a table of every translated/localized file with keyword-adaptation counts, the generated SEO assets, and explicit next steps — the placeholder URLs in the hreflang assets need real absolute URLs before publishing, and the sitemap fragment needs merging into the real sitemap.
