French and English websites: what changes and what it costs

French-speaking Switzerland presents a unique case for bilingual websites. Between Geneva's large expat community and the population's high language skills, French-English often makes more sense than the traditional French-German combination.

Creating a bilingual French-English website costs between CHF 1'200 and CHF 4'500 more than a monolingual site, depending on the method chosen. Technical configuration represents half of this additional cost, translation the other half.

The Swiss French context nobody mentions

According to the Federal Statistical Office, 52% of working-age people have active English skills in Switzerland, with 69% having passive comprehension. In French-speaking Switzerland, 66% of the population regularly uses multiple languages according to federal statistics.

Geneva hosts a large international expat community, particularly in research, international organizations and banking. The bilingual French-English international schools in Geneva and Lausanne create specific demand for content in both languages.

This demographic reality explains why many French-speaking Swiss SMEs choose English as their second language rather than German, contrary to common assumptions.

Three levels of translation and their costs

For a 3,000-word website (standard size for a business site), three approaches exist:

Pure machine translation: around CHF 30 based on international rates of USD 0.001 per word. Fast but inadequate for a professional website. Quality remains insufficient to represent a business.

Machine translation with human revision: between CHF 150 and CHF 300 for 3,000 words, 50 to 70% cheaper than pure human translation according to European cost studies. This method offers a good quality-price compromise.

Professional human translation: between CHF 360 and CHF 900 for the same volume. Maximum quality comes at a price, justified for technical or legal content.

Automated solutions like Weglot charge around CHF 17 per month for a 10,000-word site, but create technical dependency and recurring costs.

Technical configuration: hreflang and architecture

The technical portion often represents half the additional cost of a bilingual site. Hreflang configuration is considered "the most complex aspect of SEO" by experts.

For Switzerland, the recommended configuration uses fr-CH for Swiss French, en-CH for English targeting the Swiss market, and x-default for other regions. A .ch domain with subdirectories (example.ch/fr, example.ch/en) remains the optimal approach for local presence.

Hreflang tags prevent Google from considering language versions as duplicate content. Poor configuration can penalize SEO instead of improving it.

Duplicating the user interface (menus, forms, error messages) represents additional development work often underestimated.

Maintenance and updates

Every content change must be translated and verified in both languages. This constraint doubles editorial maintenance time. For a site with frequent news updates, costs can quickly become prohibitive.

Synchronizing technical updates between language versions requires particular rigor to avoid inconsistencies.

When not to create a bilingual site

An exclusively local French-speaking clientele doesn't justify the investment. If your customers come only from local word-of-mouth or direct recommendations, a French site suffices.

Budgets under CHF 8'000 for the entire project would be better spent on an excellent monolingual site rather than a mediocre bilingual one.

Businesses without resources to maintain two updated language versions create more problems than they solve. An outdated English site gives a negative impression.

Impact on total budget

For a standard business website, the bilingual surcharge represents 15 to 25% of the total budget. For a CHF 12'000 project, expect CHF 2'000 to CHF 3'000 additional.

This surcharge breaks down between initial translation (40%), technical configuration (35%) and interface duplication (25%). Maintenance then represents a recurring cost often overlooked.

Frequently asked questions

Can English be added later to an existing site?

Technically possible but expensive. Restructuring the architecture to integrate hreflang and duplicating interfaces often costs more than planning bilingual from the start. Better to anticipate this need during initial planning.

Is Google Translate sufficient for a professional site?

No. Pure machine translation creates meaning errors that harm professional credibility. At minimum, human revision of main pages is essential.

Should all pages be translated?

Not necessarily. Starting with contact, services and about pages allows testing English-speaking client interest before investing in complete translation.

How to handle bilingual contact forms?

Forms must be translated but can send to the same email. Include fields to identify visitor language to facilitate request processing.

Does English really improve SEO?

Only if you target English keywords with a real content strategy. Simply duplicating French content in English without specific keyword research provides little SEO benefit.

Creating a bilingual French-English site addresses a French-speaking Swiss economic reality but requires a methodical approach. Execution quality determines return on investment more than simply having two languages.

Our web development services integrate multilingual configuration from conception to avoid restructuring surcharges.
