Hreflang (multilingual SEO tag)

Related service Websites, web apps & online shops

DEFINITION

An HTML tag that tells Google 'this is the Hungarian version, that is the English version' of the same page. Both versions can rank, but Google serves the right one to the right visitor. Mandatory for Hungarian e-commerce sites with English content — without it Google sees duplicate content and demotes both. Configured via `<link rel="alternate" hreflang="hu" href="...">` tags in `<head>` or in the XML sitemap. Misconfiguration can cut Google traffic 30-70%.

RELATED TERMS06
  • SSR (Server-Side Rendering)→

    HTML rendered by the server per-request, fresh for every user. Ideal for dynamic content (dashboards), but slower than SSG.

  • SSG (Static Site Generation)→

    Pages are produced at build time as HTML and served from a CDN. Near-zero TTFB. DField's own site runs this way across 111+ pages.

  • ISR (Incremental Static Regeneration)→

    SSG + timed regeneration: the HTML is static but regenerates on a schedule. Ideal for blog content · freshness with CDN speed.

  • Edge rendering→

    Code runs at the CDN edge closest to the user (Cloudflare Workers, Vercel Edge). Dynamic responses with ~10–50 ms TTFB.

  • RSC (React Server Components)→

    React components that run exclusively on the server and never ship to the browser. Result: less client-side JS and faster hydration.

  • LCP (Largest Contentful Paint)→

    Time until the largest visible element paints. Google Core Web Vitals passes under 2.5s · we usually land marketing pages under 1s.
