The verdict in three sentences
A multilingual international site is not a translated site: it is a hreflang architecture, decentralized editorial management and per-market SEO. In 2026, a multilingual rebuild in Dublin starts at EUR 15,000-40,000 for two languages, with +12 to 18 % per additional language. The translation line (EUR 0.09 to 0.16/word) and the editorial retainer determine perceived quality abroad.
What makes up a multilingual rebuild
| Line item | 2026 range (EUR) | Note |
|---|---|---|
| Multilingual base rebuild (2 languages) | 15,000 – 40,000 | Technical + design foundation |
| Additional language | +12 to 18 % | Per language beyond 2 |
| hreflang architecture + subfolders | 2,000 – 5,000 | /en/ /fr/ /de/ + tags |
| Professional translation | 0.09 – 0.16 /word | Human, not raw machine |
| Decentralized editorial management (CMS) | included in base | Roles per market |
| Editorial retainer | 300 – 900 /mo | Multi-language updates |
Typical timeline: 8 to 14 weeks. The architecture choice (subfolders vs subdomains vs ccTLD) is structural for international SEO.
Subfolders, subdomains or ccTLD?
| Structure | Example | Advantage | Drawback |
|---|---|---|---|
| Subfolders | site.com/de/ | Shared SEO authority, simple | Weaker country targeting |
| Subdomains | de.site.com | Clear separation | Diluted authority |
| ccTLD | site.de | Maximum country signal | Costly, SEO per domain |
For an exporting SME, subfolders with hreflang offer the best cost/performance ratio in 2026: they pool domain authority while targeting each language.
Mini case study
Mark, export director of a B2B equipment manufacturer in Dublin, wants to rebuild his site in 4 languages (EN, FR, DE, ES) to address Europe. He budgets a bilingual base at EUR 22,000, +2 languages at +15 % each (i.e. +EUR 6,600), a hreflang architecture at EUR 3,500, and translation of 18,000 words at EUR 0.13/word (EUR 2,340/target language, ~EUR 7,000 for 3 languages from EN). Project total: ~EUR 39,000, 12-week timeline, plus EUR 600/month editorial retainer. With a target of 3 new export clients/year at an average deal of EUR 25,000, the site self-funds on the first signature.

Human or AI translation in 2026?
AI drafts, but an SME selling internationally needs human post-editing (EUR 0.09-0.16/word) for domain terminology and credibility. Raw machine translation is spotted and damages the B2B image.
Is hreflang really necessary?
Yes as soon as you have multiple language versions. Without hreflang, Google may serve the wrong version, create perceived duplicate content and dilute ranking. Its correct implementation (EUR 2,000-5,000) is non-negotiable.
How much does an additional language cost?
Expect +12 to 18 % of the technical base per language beyond two, plus per-word translation cost. Most of the extra cost is editorial (content, local SEO), not technical, since the architecture is shared.
Do you need an SEO writer per market?
Ideally yes for priority markets: keywords do not translate literally. A word-for-word transfer misses local search intent. The editorial retainer (EUR 300-900/month) covers this steering.
Can we launch 2 languages then add the others?
Absolutely, and it is often recommended. Lay the bilingual base, validate the market, then add languages in stages at +12-18 % each. This smooths investment and risk.
