Going Global: Top 10 Languages for International Business Growth
Generative AI‑driven search surfaces quick, authoritative answers. If your page isn’t the clearest result in the user’s language, you miss out on clicks and revenue. Multilingual content has shifted from nice‑to‑have to a competitive moat.

Key takeaways 

  • English, Chinese and Spanish still dominate, but Hindi and Korean growth keeps them on every strategist’s radar.

  • AI‑enabled translation + expert post‑editing can cut time‑to‑market by up to 40 % for high‑volume content.

  • Localised customer journeys lift conversion by 70 % (CSA Research); Google’s 2024‑25 Helpful Content update rewards language‑appropriate answers.

It's clear the world is becoming increasingly connected, and business today is certainly international. Most global companies have at least given thought to the many possibilities that could arise with providing their content in different languages. 

In fact, any business aspiring to sell its products and services to audiences with different cultural and linguistic backgrounds will need to take its content to the next multilingual level. 

To successfully engage audiences, you should do it in their preferred language. Whether that's through  localizing online training to better communicate with employees, translating user guides and product manuals for customer support, or localizing your website to attract visitors from across the globe. 

Defining a translation and localization strategy for your business is becoming ever more necessary, as it paves the way forward for these global interactions. Yet, with 7,000 known living languages, it can be difficult to decide which language(s) your company should invest in providing. 

Your first assessment should be looking at your macro-level business goals and core target audiences. Before diving into the language pool, look at what languages your competitors are using to distribute their content and how relevant they are to mimic or move away from. But that’s not all.

A localization strategy is key, and a huge piece of the localization puzzle is all about the efficient management of digital content. Your strategies also need to consider global connectivity and how you manage your global content as you devise a globalization strategy and use it as a competitive advantage.

We’ve compiled a handy list of the top 10 languages in high demand that you should consider to initiate global growth for business and marketing content translation. Check the facts and figures on why they are the best bet for your global growth.

 

1. English: the universal baseline

 

English is the lingua franca of business and academia—spoken in 94 countries by 339 million native speakers and the official language of the 20 most influential international organizations.

  • Primary foreign language in schools worldwide, giving it reach to one-third of the planet’s population.

  • Top online language with 1 186 451 052 internet users and present on 61 % of all websites.

  • Crucial for global success: any company aiming to thrive internationally needs a solid English-language strategy.

2. Chinese: scale where others can’t

 

Chinese refers to a group of Sino-Tibetan languages with over 955 million native speakers—that’s 14.4 % of humanity and roughly 1 billion speakers worldwide.

  • The Chinese economy has grown spectacularly, overtaking the U.S. in 2018 to become the world’s largest.

  • Its economic dominance makes Chinese a must-have business language, especially since English is not widely spoken in China.

  • It’s the second-most popular language online, and with US $2 779.31 billion in ecommerce sales (2021), China leads the global e-commerce market.

  • As Asian internet adoption keeps climbing, Chinese could soon dethrone English as the top internet language.

  • Mandarin is the main spoken dialect, but written content must use either Simplified Chinese (mainland) or Traditional Chinese (Taiwan & Hong Kong).

  • Tip: Use Simplified for mainland audiences, Traditional for Taiwan and Hong Kong—see the table below for full market variations.

Markets Spoken Written
China Mandarin Simplified Chinese
Singapore Mandarin Simplified Chinese
Taiwan Mandarin Traditional Chinese
Hong Kong Cantonese Traditional Chinese

If you need a Chinese interpreter for a business meeting or appointment, your choices are between Mandarin and Cantonese. If you have a document to translate, however, the choices are between Simplified and Traditional Chinese.

 

3. Spanish: gateway to 20+ markets

 

Spanish boasts 460 million native speakers, making it the second-most spoken language after Mandarin.

  • Opening Spanish-language channels unlocks major markets: Spain plus key Latin American economies such as Mexico, Peru, Paraguay and Ecuador.

  • In the United States, 37.6 million people speak Spanish as their first language, and the Hispanic population is projected to double by 2050—a pivotal factor in the world’s second-largest economy.

  • The British Council reports Spanish is ‘useful’ for 34 % of UK businesses, underscoring its commercial relevance in Europe.

  • Mexico’s extensive bilateral trade agreements create some of the most open trade conditions globally, while the UK has prioritized Mexico for international education partnerships.

Bottom line: If you plan to do business in the US—or virtually anywhere across the Western Hemisphere—Spanish must be a core localization language in your strategy.

 

4. Arabic: voice of a fast‑growing, mobile‑first demographic

 

Arabic counts 295 million native speakers and is the official language of 28 countries, many among the fastest-growing economies in the Middle East and Africa.

  • Six Arabic-speaking nations rank in the UK’s top-50 goods-export markets, with a combined value higher than Spain, China or Italy—hence Arabic’s spot as the #2 “language of the future” (British Council).

  • The Middle East is a high-growth, high-spending consumer region; governments heavily promote tourism and shopping, amplifying business opportunity.

  • Regional instability increases demand for Arabic-language intelligence and diplomatic content, widening the market beyond commerce.

  • Rapid internet adoption, coupled with many users speaking only Arabic, makes online-content translation essential for international competitiveness.

  • Recent tech advances have removed most website-rendering challenges, so more brands are localizing into Arabic.

  • Ensure your products and services are available in Arabic to seize growth—especially in the diplomacy, energy and defense sectors, where language alignment is mission-critical.

5. German: Europe’s R&D powerhouse

 

130 million native speakers (230 million total) and the 4ᵗʰ most-used language online.

  • Dominant in Europe’s economic heavyweights: Germany, Austria, Belgium, Switzerland, Luxembourg and Liechtenstein—Germany itself is the EU’s largest economy.

  • #3 global spender on R&D, making German critical for scientific research in health, social sciences, psychology, arts & humanities.

  • German companies are famed for quality, craftsmanship and innovation—to earn their business, you need their language.

Key takeaway: German markets show high acceptance of machine-translation + human review for technical documentation, enabling efficient, scalable localization.

 

6. Portuguese: Brazil drives cross‑continental growth

 

Portuguese boasts ~232 million native speakers across Portugal, Brazil and several African nations, making it the second-most spoken language in Latin America.

  • It ranks 5ᵗʰ for internet usage with 171 million users, and CSA Research notes a 6.1 % share jump in the latest language benchmark.

  • Brazil is the focal market—Latin America’s largest economy and a rapidly expanding hub for business opportunities.

  • Brazil is also the most cited science base outside the G8, offering collaboration potential in pharma and energy.

  • The British Council lists Portuguese among the top-ten “languages for the UK’s future”, citing trade, science, education and diplomacy prospects.

  • Demand is rising in the US, and the language is gaining traction in Asia due to strong ties with Portugal and other Lusophone countries.

  • According to UNESCO, Portuguese is the fastest-growing European language after English and carries the highest growth potential in southern Africa and South America.

Key takeaway: Use Portuguese to unlock multi-continent growth—pair AI interpreting with localized e-learning to onboard LATAM teams efficiently.

 

7. French: link to Europe, Africa & Canada

 

French counts 79.9 million native speakers in 29 countries, with an additional 194.2 million second-language speakers—a figure projected to reach 750 million by 2050, potentially overtaking English and Mandarin.

  • Around 102 million Francophone internet users keep French a valuable digital market.

  • Official language of major international organizations (UN, WTO) and likely to see increased use within the European Union.

  • Francophone Africa is booming—three of the five fastest-growing African economies (Rwanda, Tanzania, Mozambique, Côte d’Ivoire, DRC, Ethiopia) include French as an official language.

  • In regions where English proficiency is low—Algeria, Morocco, Vietnam, Cambodia—French serves as a critical lingua franca.

Key takeaway: Localizing into French opens doors across Europe, Africa and parts of Asia—making it a strategic language for long-term global growth.

 

8. Japanese: tech‑savvy and detail‑oriented

 

125 million native speakers concentrated in Japan—the world’s third-largest economy.

  • 6ᵗʰ-largest language online, with US $128.3 billion in ecommerce sales (2021).

  • The British Council calls Japan a “significant contributor to UK prosperity,” highlighting science and technology opportunities.

  • 2ᵈ-largest global investor in R&D; Japanese firms are renowned for innovation and engineering excellence.

  • Key partner in climate policy, energy and financial-system reform, according to the UK Foreign & Commonwealth Office.

  • Robotics powerhouse: ≈250 000 industrial robots today, projected to exceed 1 million, with robotics revenue near US $70 billion by 2025.

 

9. Hindi: India’s digital explosion

 

Hindi is the fourth most-spoken language worldwide with 343.9 million native speakers.

  • India ranks 7ᵗʰ in land area, 2ⁿᵈ in population and is arguably the fastest-growing major economy.

  • India’s huge consumer base and rich cultural diversity make Hindi a prime future localization market across text, audio, video and advertising.

  • While India has 128 million English speakers, about 85 % of the population doesn’t speak English, so local-language content is essential.

  • Hindi’s online presence grew 66 % in CSA Research’s Top-100 Online Languages, fuelled by mobile penetration and government initiatives.

  • Proposals to make Hindi an official UN language would require all UN documents to be provided in Hindi—underlining its rising global status.

Bottom line: India’s demographics and economic momentum drive surging demand for Hindi-localized content, making the language a strategic investment for global businesses.

 

10. Korean: small population, high spend

 

Korean is the world’s 13ᵗʰ most-spoken language, official in both North and South Korea and recognised as a minority language in China and parts of Japan.

  • With ≈ 81 million native speakers, South Korea ranked as the 6ᵗʰ-largest ecommerce market last year, generating US $92 billion in online sales.

  • This market is projected to grow 5 % over the next three years, hitting about US $140 billion.

  • Korea is home to powerhouse brands Samsung, Kia, Hyundai, Fila and LG, proving its global industrial clout.

  • Duolingo lists Korean as the 7ᵗʰ most-studied language worldwide, signalling rising international interest.

Bottom line: As the Korean-speaking audience expands, localising into Korean taps a high-spend, tech-savvy market for sustained business growth.

  • KR ecommerce reached US $92 bn in 2024 and keeps rising

  • Localize microcopy within super‑apps (Coupang, KakaoTalk) for true immersion

 

Keep an Eye on the Fast-Rising

  • Language needs will evolve as your global customer base grows—expect to add new locales over time.

  • Top-10 lists are indicative only: for specialised markets, other languages may outrank our picks (e.g. Italian currently outpaces Arabic in EU-mandated translations).

  • Emerging mobile markets matter: Malaysia’s near-universal smartphone use could make Malay a priority for app and website localisation.

  • Rising stars online: Thai, Indonesian and Persian are surging in CSA Research metrics thanks to government-driven internet expansion.

  • Ukrainian demand has exploded—45 million native speakers plus diaspora needs have driven a 500 % spike in Duolingo learners and soaring T&I requests.

Action point: Monitor community demographics; if sizeable Ukrainian (or other emerging-language) audiences appear in your target regions, add those languages to your localisation roadmap.
