Many company leaders still believe an English-first approach is enough for global operations. That perspective overlooks a fundamental reality: native English speakers are a minority of the global population, and an English-only strategy quietly excludes the majority of potential customers.
The conversation needs to shift from viewing translation as a cost center to recognizing it as a strategic investment in market expansion. The question is no longer whether to invest in translation, but how to build the data-driven case for it.
The English-is-enough myth in numbers
The perception that English is the universal language of business is a persistent myth, and the data reveals a sharp disconnect between online content and consumer reality. While English dominates the largest share of top websites, that figure reflects the language of content producers, not the preferences of the global consumer base.
The vast majority of the world’s online population does not speak English as a first language. CSA Research’s widely-cited “Can’t Read, Won’t Buy” findings show that consumers are significantly more likely to purchase when product information appears in their native language, and a majority actively avoid English-only websites altogether. More than half of your potential international audience may never even consider your products if you don’t speak their language.
An English-only website doesn’t just create a hurdle. It builds a wall. For any company serious about international expansion, these patterns signal that translation is not an add-on but a fundamental requirement for market entry.
Revenue and market data that make the case
Beyond user preference, the financial argument for localization is what resonates with leadership. Strategic investment in localization correlates with measurable revenue growth and stronger market penetration.
Companies that localize professionally consistently report meaningful lifts in conversion and new-market sales. The logic is straightforward: customers who understand what they are buying are more confident, and more likely to complete the purchase. The financial risk of not localizing is equally clear. A large share of online shoppers in non-English-speaking countries rarely or never buy from English-only sites, representing a self-imposed cap on total addressable market.
The Airbnb expansion is a documented example of how deep localization unlocks growth. In partnership with Translated, Airbnb scaled its multilingual content program across dozens of markets and languages, supporting one of the fastest international expansions in the travel industry. The full story, including the specific languages and outcomes, is captured in the Airbnb language expansion case study.
This is the pattern that defines effective localization programs: it isn’t translation alone, it’s a strategic decision that unlocks markets. Forward-thinking businesses scale this work through Language AI solutions that combine machine speed with human expertise: the Human-AI Symbiosis principle that AI should empower professional translators rather than replace them.
Customer experience metrics by language
While revenue figures are compelling, the longer-term value of translation shows up in customer experience and loyalty. Language is a tool for building trust, and customers who feel understood become repeat buyers.
Industry research consistently shows that customers feel more loyal to brands offering native-language support and localized content. The reverse is also true: a meaningful share of consumers will switch to a competitor that supports them in their language, and contact-center leaders consistently report higher satisfaction scores when interpretation is available. Lost customers are a direct, documented cost of language gaps. (Source: CSA Research.)
Investing in language accessibility is therefore a direct investment in retention. It demonstrates respect for the customer and an understanding of their needs, which is what separates global brands from companies that merely operate internationally.
Framing translation as growth investment, not cost
To secure executive buy-in, reframe the entire conversation. Translation is not a tactical expense to be minimized; it is a strategic investment that generates measurable returns. The focus must shift from the upfront cost of translation to the opportunity cost of not translating.
An effective business case connects every dollar spent on localization to a clear business objective: entering a new market, increasing conversions, or improving retention. The data above provides the foundation. Localization is a prerequisite for capturing the global majority who don’t transact in English.
This is where the right technology stack matters. Underpinned by Language AI, your localization program can be measured against Time to Edit (TTE), our metric for machine translation quality, defined as the average time a professional translator spends bringing a machine-translated segment to human quality. Overarching that, TranslationOS acts as the centralized hub for global content, synchronizing assets across markets to prevent brand drift and giving leadership the visibility and control they expect from any other strategic operation.
The most persuasive question for any CEO is not “What will it cost to translate?” but “What revenue are we leaving on the table by choosing not to?”

The evidence is clear: limiting a business to a single language is a significant barrier to growth. Translation is the key to unlocking global markets, building meaningful customer relationships, and establishing a brand that resonates internationally. A multilingual strategy isn’t just about reaching new audiences. It’s the foundation for long-term, sustainable success.
