Internationale SEO
Rank in meerdere landen en talen — hreflang, locale routing en meertalige contentstrategie.
International SEO correct uitgevoerd
International SEO is niet zomaar het vertalen van uw content. Het gaat om hreflang-implementatie, locale-specifieke URL-structuren, land-specifieke contentstrategie, en technische signalen die Google vertellen welke pagina aan gebruikers in welk land moet worden getoond. Fout gedaan, kan dit leiden tot penalties voor duplicate content. Correct gedaan, vermenigvuldigt het uw organische traffic.
Hreflang: de technische basis
hreflang-attributen vertellen Google dat deze twee pagina's dezelfde content in verschillende talen of voor verschillende regio's zijn. Elke pagina in elke locale moet verwijzen naar alle andere locale-varianten. Ik implementeer dit als een server-gegenereerde sitemap en in-page head tags — beide zijn vereist voor maximale betrouwbaarheid.
Locale routing-strategieën
Ik implementeer drie URL-strategieën, afhankelijk van uw vereisten: subdirectories (example.com/en/, example.com/de/), subdomains (en.example.com, de.example.com), of ccTLD's (example.co.uk, example.de). Subdirectories zijn voor de meeste projecten het meest praktisch — zij concentreren domain authority en geven duidelijk de locale aan.
Common questions
What is hreflang and why does it matter?
Hreflang is an HTML attribute that tells Google which version of a page to show users in which language or country. Without it, Google may show the wrong language variant to users, or treat your translated pages as duplicate content. Correct hreflang implementation is the technical foundation of international SEO.
Should I use subdirectories, subdomains, or ccTLDs?
Subdirectories (example.com/en/) for most projects — they inherit domain authority and are easiest to manage. Subdomains (en.example.com) if you need separate hosting per locale. ccTLDs (example.de) for maximum local trust signal in specific markets, but only if you can manage separate domains.
How do you handle machine translation for multilingual sites?
Machine translation (DeepL, Google Translate) is a starting point, not an endpoint. I flag content for human review and prioritise high-traffic pages for native translation. For SEO purposes, unique translated content always outperforms direct machine translation.
What is the biggest mistake in international SEO?
Not implementing hreflang correctly — specifically not including the x-default tag, and not making hreflang bidirectional (both pages must reference each other). The second biggest mistake is translating content without adapting it for the target market''s search intent.
Can you implement international SEO on an existing Next.js site?
Yes. Next.js has built-in i18n routing. I add hreflang to the head, set up locale-specific sitemaps, and configure content delivery to serve the correct locale based on the URL or Accept-Language header.
