nFADP Quadrilingual Hreflang & Core Web Vitals
Technical SEO for Swiss Brands
Switzerland's quadrilingual requirement creates the most complex technical SEO hreflang architecture in Europe — correct language targeting requires hreflang="de-CH" for Swiss German, hreflang="fr-CH" for Swiss French, hreflang="it-CH" for Swiss Italian, and hreflang="en" for international English, all correctly implemented and verified in Google Search Console. ithouse.tech's Switzerland Technical SEO covers this quadrilingual architecture: hreflang implementation for all four Swiss linguistic variants, nFADP-compliant tracking configuration, Core Web Vitals optimisation for Zurich, Geneva and Basel audiences, Ricardo.ch structured data schema for Swiss marketplace sellers, and Google.ch crawl configuration. Combined with our Switzerland SEO services, on-page SEO, and Switzerland local SEO, technical SEO builds the multilingual foundation that Google.ch rewards.
