Desarrollo de Plataforma de Localización Multilingüe

We generate hreflang annotations programmatically from the content graph—every page knows its locale variants at build time. Our CI/CD pipeline runs automated validation on every deploy, checking for orphaned tags, missing reciprocals, and conflicting canonicals. This catches errors before they reach production, which matters because a single hreflang mistake can cause Google to ignore the entire tag set for a page.

First-pass AI accuracy varies by language pair—European languages hit 80-85% immediately, CJK languages around 70-75%. After three months of translation memory accumulation and model fine-tuning on your brand voice, accuracy typically reaches 85-90% for most content types. Human review then becomes a spot-check rather than a full rewrite, cutting review time by 40-60%.

We use a multi-signal detection stack: GeoIP identifies the country, the Accept-Language header reveals browser preference, and a cookie stores explicit user choice. For Switzerland, GeoIP returns CH, then we check the browser language to distinguish de-CH, fr-CH, or it-CH. Users can always override via a language selector, and that preference persists across sessions via cookie and optional database storage.

Yes—that's the core advantage of our architecture. Adding a new locale means creating the locale configuration in the CMS, activating the translation pipeline for that language pair, and deploying. Hreflang generation, URL routing, and sitemap creation all adapt automatically. We've designed for 30 languages from day one, but the system handles 50+ without architectural changes. A new language typically takes 2-3 days of configuration work.

Our frontend architecture uses logical CSS properties (`margin-inline-start` instead of `margin-left`) and `dir` attributes at the HTML level. The CMS content model flags RTL locales, and the rendering layer adapts layout direction, text alignment, and navigation order automatically. We test every component in both directions during development—RTL isn't a post-launch patch, it's baked into the design system.

A full 30-language platform with translation pipelines, hreflang infrastructure, and edge routing typically takes 10-14 weeks and falls in the $80,000-$200,000 range depending on content volume, CMS complexity, and custom editorial workflow requirements. Ongoing translation pipeline management and locale expansion support runs $3,000-$8,000/month on a retainer basis.
