Which Language Should You Choose First to Sell Internationally?

Choosing a first language for selling internationally may seem simple. Many companies instinctively think of English. English remains a bridge language for negotiating, prospecting and presenting an offering to international customers.

But starting with English is not always the best strategy. If your first target market is Germany, Spain, Italy, Japan or Brazil, the language that builds trust and drives sales is not necessarily the one your teams speak best. It is often the language of the target market.

The right question, therefore, is not simply: “Which language is most widely spoken?” Instead, you should be asking: “Which language will help me sell faster, with fewer barriers, in the market with the greatest potential?”

Is English always the best first choice?

English is often a sensible first choice when a company has not yet decided which country to prioritise. It serves as a common language at trade fairs, in tender processes, B2B communications and meetings with distributors.

English is therefore an excellent starting point if you are targeting several markets at once, if your offering is B2B, technical or SaaS-based, or if your prospects already buy in English. However, English alone may not be enough when purchasing decisions rely heavily on trust, detailed product information, after-sales support, regulatory compliance or the online shopping experience.

This approach also ties in with the concept of a pivot language. As we explain in our article on the translation chain, English can serve as an intermediate base for organising a multilingual project, provided that this version is checked, approved and then adapted to the target languages.

This is also evident in cross-border e-commerce. According to Unbabel's Global Multilingual CX Report, 57% of consumers surveyed would consider a lack of customer support in their native language a form of bias. This highlights how providing customer support in local languages remains an important consideration for businesses looking to sell internationally.

Why using the local language often leads to higher conversion rates

Language directly influences credibility. A prospect may understand English but prefer to buy in German, Spanish or Italian when comparing prices, checking warranty details or making a payment. Making a purchase also requires a sense of familiarity and security.

This is even more true in sectors where perceived risk is high, such as technical products, medical devices, professional software, machinery, finance, legal services and luxury tourism. In these cases, simply translating a homepage into English is not always enough. Product pages, trust-building pages, FAQs, automated emails and, in some cases, instructions for use also need to be localised. For this type of project, website translation designed with international SEO in mind is often more effective than a partial translation carried out in a hurry.

Which language to choose first to sell internationally: a 5-criteria approach

The choice depends on your products or services, your budget and the market you are best placed to serve. The first criterion is the country’s commercial potential. A language should not be prioritised solely because it seems important. Choose it because it gives you access to a market where there is demand, your margins are viable, logistics are manageable and you can compete effectively. The UK government's business.gov.uk portal similarly recommends analysing the potential of target markets, including market size, purchasing power, competition, barriers to entry and local consumer behaviour, before developing an international SEO strategy.

The second criterion is how closely the market aligns with your existing sales. If you are already receiving enquiries from Germany, Spain or the Netherlands, your data may already point to the language you should prioritise, whether in your CRM, website analytics or incoming enquiries.

The third criterion is the level of trust required. The more complex, expensive or heavily regulated your product is, the more important the local language becomes. A buyer may be able to read a presentation in English but will often prefer to receive instructions for use, technical documentation or a contract in their own language. Research published in International Studies of Economics highlights how the ability to communicate in a common language directly influences international trade, particularly when products are complex and require more detailed exchanges between buyers and sellers.

The fourth criterion is the cost of implementation. Some languages may be strategically important but require more work in terms of cultural adaptation, customer service, local regulations, tailored SEO, currencies, payment methods, address formats and regulatory documentation. The OECD highlights how differences in platforms, currencies, languages, payment systems and regulatory requirements can create significant barriers to international growth.

The fifth criterion is your ability to deliver on your promises after translation. Translating a sales page into Italian only makes sense if you can respond to Italian prospects, process orders, handle returns and maintain the customer experience. Your language choice therefore has implications for the entire company.

English, German, Spanish, Italian: which should you choose for the European market?

In Europe, the choice is more complex than it may first appear. The European Union has 24 official languages and upholds multilingualism as an institutional principle.

For a company, English may make communication easier, but it is no substitute for speaking to customers in their own languages. The recent debate over the growing dominance of English in EU trade negotiations, reported by Euronews, illustrates this tension: while English can speed up technical discussions, multilingualism remains essential to ensuring transparency, precision and acceptance across the EU.

In practice, German is often a priority for industrial, technical and B2B companies targeting Germany, Austria or German-speaking Switzerland. Spanish is highly relevant for Spain, but also serves as a gateway to Latin America. Italian can be a strategic choice in sectors such as design, manufacturing, tourism, luxury goods, healthcare and specialist retail.

The key principle to remember is this: do not choose a language simply because it is prestigious. Choose it because it gives you access to an opportunity you can turn into sales.

Translate, localise or create directly in the target language?

Translation is necessary, but it is not always enough. Translation involves conveying the meaning of a text in another language. Localisation involves adapting the message to the target market, taking into account cultural references, tone of voice, units of measurement, currency, purchasing habits, formats, trust signals, keywords and social proof.

This is why effective marketing translation must go beyond the words themselves. It must preserve the commercial intent. The message should feel as though it was written specifically for local customers, not simply translated from a French brochure.

The right way to roll out a multilingual strategy

To avoid spreading your budget too thinly, start with a phased rollout. You do not need to translate your entire website into eight languages from the outset. A more effective approach is to test, measure and then expand.

The first step is to translate or localise the pages that actually drive sales. This includes your international homepage, priority product or service pages, forms, customer testimonials, contact pages and trust-building content. The aim is to create a complete customer journey in the chosen language.

The second step is to adapt your SEO strategy. Keywords cannot simply be translated word for word. A French keyword may have low search volume in one language, while a more natural equivalent is used in another.

The third step is to expand. Once the first language has been validated, you can add a second one on a much stronger foundation, with a glossary, translation memory, editorial style guide, page templates, validation process and SEO monitoring in place. This is where a translation company can help structure the project rather than treating each translation as a standalone task.

The common errors to avoid

• Choosing a language simply because a member of your team speaks it, rather than based on the market’s actual potential.
• Translating only the visible pages of your website while leaving forms, delivery terms and confirmation emails in the original language.
• Overlooking customer support in the target language, even though the post-purchase experience also plays an important role in building trust.
• Using machine translation without proofreading for sensitive commercial content, risking a loss of accuracy, tone and credibility.

Conclusion: start with the language that removes the greatest barriers to doing business

So, which language should you choose first when selling internationally? If you have not identified a priority market, English is often a sensible starting point. But if your data points to clear potential in a specific country, prioritise the local language over a purely global approach.

The best decision combines sales potential, customer trust and your operational capacity to serve that market. A successful multilingual strategy is not about being present everywhere. It is about being credible, clear and convincing in the markets where your sales potential is greatest.

Start with one language, but choose it as a business investment.
