Building a 16-Language Next.js Static Site with Full SEO Alternates

Reaching global players requires multi-language support. We chose Next.js App Router and next-intl to build a static generated site supporting 16 languages, complete with hreflang alternate links in the sitemap.

Static Exports and Alternates

Our site compiles fully statically to run on Cloudflare CDN. By defining generateStaticParams for every language page, Next.js generates static HTML folders. Our custom sitemap script dynamically adds language alternate nodes for every page to maximize international SEO coverage.
