In today’s hyperconnected economy, businesses can reach customers across the globe with just a click. But if your website doesn’t speak your customer’s language, your global expansion strategy is likely to stumble. Multiple studies confirm a powerful truth: language is not only a medium of communication, but also a driver of trust, loyalty, and sales.

What the Numbers Tell Us

Let’s start with some striking statistics from respected international sources:

  • According to Think with Google, 72% of consumers spend most or all of their time on websites in their own language.
  • A study highlighted by Helsingborg Innovation District revealed that 72% of customers prefer to shop from sites in their mother tongue, and 76% are more likely to buy products when product information is in their native language.
  • Weglot (2025) reported that nearly 73% of customers prefer to purchase a product or service from a site that offers information in their own language.
  • OneSky.ai (2025) emphasized that 72% of shoppers are more likely to buy from sites written in their native language.

These converging data points paint a crystal-clear picture: multilingual content is not a luxury, it’s a business imperative.

The Landmark Study: Can’t Read, Won’t Buy

The most authoritative research on this subject comes from CSA Research (formerly Common Sense Advisory). Their survey “Can’t Read, Won’t Buy – B2C” involved 8,709 consumers in 29 countries between late 2019 and early 2020. The results are revealing:

  • 76% of consumers prefer to buy products described in their native language.
  • 40% say they would never buy from websites in other languages.
  • 73% want product reviews in their own language.
  • 75% are more likely to repurchase from the same brand if customer care is offered in their language.
  • Even among people with good English skills, 66% still prefer to buy when information is available in their mother tongue. This preference rises to 85% for those with limited English proficiency.

The conclusion is undeniable: language directly affects buying decisions. For brands, this means that cutting corners on translation can lead to losing customers—often before they even add a product to their shopping cart.
