The verdict in three sentences
A multilingual website is not a translated website: it is an architecture designed around hreflang, international indexing and two distinct customer journeys. In Dakar in 2026, expect a premium of 25 to 45 % per additional language versus an equivalent monolingual site. The real lever is not machine translation but SEO consistency between versions, which decides whether the diaspora finds you on Google.fr as well as Google.com.
How much multilingual costs in 2026
The budget depends on page count, translation type (post-edited machine vs professional) and the technical handling of international SEO. Here are the 2026 orders of magnitude for a Dakar corporate website.
| Service | Monolingual FR | Bilingual FR/EN | Premium |
|---|---|---|---|
| 8-page showcase site | 1,500,000 FCFA | 2,000,000 FCFA | +33 % |
| 20-page corporate site | 3,500,000 FCFA | 4,800,000 FCFA | +37 % |
| Site + blog + careers | 4,500,000 FCFA | 6,000,000 FCFA | +33 % |
| Professional translation (word) | — | 90 FCFA/word | — |
| Post-edited machine translation | — | 35 FCFA/word | — |
Professional translation remains essential for commercial and legal pages; post-edited machine translation suits high-volume blog articles.
hreflang, latency and the diaspora journey
The technical detail that separates an amateur site from a professional one is the hreflang tag. It tells Google which version to serve based on the visitor's language and country, preventing the English version from cannibalizing the French one. A poor implementation drops international organic traffic by 20 to 40 %.
| Technical element | Impact | Effort |
|---|---|---|
| FR/EN hreflang tags | +15-30 % diaspora traffic | Low |
| Low-latency CDN (Europe/US) | -300 ms load time | Medium |
| Localized /fr /en URLs | Better indexing | Low |
| Multilingual sitemap | Full indexing | Low |
| Translated SEO metadata | +10-20 % clicks | Medium |
For the Senegalese diaspora in France and the United States, a CDN with points of presence in Europe and North America cuts load time by several hundred milliseconds, directly improving conversion rate.
Mini case study
Aminata runs a consulting firm in Dakar serving Senegalese SMEs and diaspora investors. Her monolingual FR site drew 1,200 visitors/month, 15 % of them from France with no conversion. Moving to a bilingual FR/EN site at 4,800,000 FCFA, with hreflang and a European CDN, international traffic rises to 380 qualified visitors/month. With a 4 % conversion rate and an average deal of 2,500,000 FCFA per consulting engagement, she wins 2 new contracts in the first year, delivering a return above the multilingual investment in under six months.

FAQ
Should I translate the whole site or only key pages?
Start with commercial-intent pages (home, services, contact) and the 5 to 8 best-performing articles. Translating a full 40-article blog can add 1,400,000 FCFA with no guaranteed immediate return.
Is Google's automatic translation enough?
No for your commercial pages: it harms credibility and SEO. For blog volume, post-edited machine translation at 35 FCFA/word is a good quality/price compromise.
How long to deliver a bilingual site?
Expect 4 to 7 weeks for a 20-page corporate site, versus 3 to 5 weeks monolingual. Translation and proofreading add 1 to 2 weeks.
Is hreflang really necessary if I mainly target Dakar?
Yes as soon as you target the diaspora: without hreflang, Google may serve the wrong language and drop your international traffic by 20 to 40 %.
Can I add a 3rd language later?
Yes if the architecture is planned from the start. Adding Arabic or Wolof afterward costs 20 to 30 % of the initial budget, versus 50 % if the site was not built for multilingual.
