Why a multilingual website changes everything for the diaspora
The Senegalese and African diaspora is multilingual by nature. A Senegalese in Paris searches in French, a Senegalese in Toronto or New York often searches in English, a Senegalese in Milan mixes both. If your site exists only in French, you are invisible to a significant part of your most profitable market.
Building a well-made bilingual FR EN site is not just a matter of translation. It is a technical architecture, an editorial effort, a currency strategy and SEO discipline. Done badly, multilingual can hurt ranking with poorly tagged duplicate content. Done well, it doubles the addressable audience and credibility.
The technical foundations
A clear URL structure
Three main approaches exist to handle languages:
- Subdirectories: example.com/fr and example.com/en, the most common and simplest to manage
- Subdomains: fr.example.com and en.example.com
- Separate domains per country, heavier, reserved for large players
For a Senegalese business targeting the diaspora, subdirectories are almost always the right choice: simple, robust and easy to get indexed.
Hreflang, the decisive element
Hreflang is the tag that tells Google which version to show to which user based on their language and country. Without correct hreflang, Google may show the French version to an English-speaking user, or treat your two versions as duplicate content.
The rules to follow:
- Each page must declare all its language variants, including itself
- Use the right codes: fr, en, and possibly fr-FR, en-US, en-CA to target countries
- Add an x-default tag for the default version
- Declarations must be reciprocal: if the FR page points to the EN page, the reverse must be true
This is exactly the mechanism Kolonell uses via the translationSlug field that links each article to its version in the other language.
Performance on 3G and 4G
The diaspora has good connectivity, but it often shares links with family back home, who are on 3G. A fast, lightweight site, with images optimised in WebP and AVIF, serves both audiences. Performance remains a conversion and SEO criterion.
Content: translating is not enough
Localise, not just translate
A word-for-word translation rings false. Good EN content for the diaspora in the United States uses the right terms, the right examples and the right tone. Cultural references, city examples and amounts must be adapted to the target audience.
Answer search intent by language
A French-speaking user types "send gift to family Senegal", an English speaker types "send gift to family in Senegal". These are not the same keywords. A real multilingual strategy does distinct keyword research per language, not a simple translation of the titles.
Reassurance content in each language
Proof, guarantees and testimonials must exist in both languages. A testimonial in French does not reassure an English-speaking customer, and vice versa.
Currencies: speaking the language of money
Display FCFA, EUR and USD
A price only in FCFA forces the customer in Paris to pull out a calculator and kills the buying impulse. Showing the price in the customer's currency is a powerful conversion lever.
Smart detection
Detecting the visitor's country allows showing the right language and currency by default, while keeping a visible selector to switch manually. You must never force or trap the user in a language they do not want.
The UX of the language selector

Visible but not intrusive
The language selector must be easy to find, at the top of the page, with clear labels. Avoid flags alone as language indicators, since a flag represents a country, not a language. Prefer the labels FR and EN.
Keep the context
When the user switches language from a page, they must land on the equivalent version of that page, not on the homepage. This is exactly the role of the per-page translation link. Always sending to the homepage frustrates the user and loses the sale.
International SEO
Avoiding duplicate content
The number one risk of badly done multilingual is duplicate content. Reciprocal hreflang, distinct URLs and genuinely localised content solve this problem. Google then understands these are two language versions, not two competing pages.
Build authority in each language
Earning links and mentions from French and English sites strengthens each version. Bilingual blog content, like Kolonell's, feeds SEO in both languages and captures the search intent of the whole diaspora.
Sitemap and indexing
A clean sitemap that lists all language versions, submitted to Google Search Console, speeds up indexing. Checking in Search Console that the right versions show for the right countries is an ongoing discipline.
Mini case study: Maison Teranga, a craft brand
Maison Teranga, a Senegalese craft products brand, sold only via a French-language site and mainly reached France. Kolonell built a complete EN version with reciprocal hreflang, English-language keyword research, prices displayed in EUR and USD, and a language selector that keeps the page context. Within a few months, traffic from English-speaking Canada and the United States grew clearly, and a new share of orders came from customers searching in English for Senegalese homeland products. Simply existing in English opened an entire market that had been invisible until then.
The checklist of a good multilingual diaspora site
- Subdirectory structure fr and en
- Reciprocal hreflang and x-default on each page
- Localised content, not just translated, with keywords per language
- Currencies FCFA, EUR and USD with smart detection
- Visible language selector that keeps the page context
- Performance optimised for 3G and 4G
- Multilingual sitemap submitted to Search Console
- Reassurance content in both languages
FAQ
Why is a bilingual site important for the diaspora?
Because a significant part of the diaspora in the United States and Canada searches in English. A French-only site is invisible to them. A bilingual FR EN site doubles the addressable audience and credibility with a high-value market.
What is hreflang and why is it decisive?
Hreflang is the tag that tells Google which language version to show to which user. Without correct reciprocal hreflang, Google may show the wrong language or treat your versions as duplicate content, which hurts ranking.
Should I display prices in multiple currencies?
Yes. Showing FCFA, EUR and USD spares the customer from calculating and lifts conversion. Country detection lets you show the right default currency, while keeping a selector to switch manually.
Is translating my site enough for international SEO?
No. A word-for-word translation does not capture the right search intent. You need distinct keyword research per language, genuinely localised content and reassurance content in each language to perform in both markets.
How do I avoid hurting my ranking with multilingual?
By using distinct URLs, reciprocal hreflang with x-default, genuinely localised content and a multilingual sitemap submitted to Search Console. These elements avoid duplicate content and let each version rank well.
