The international expansion of a digital business requires a solid multilingual infrastructure to gain the trust of buyers all across the world. In a highly competitive global market, brands needs to adapt their content to ensure the user experience feels natural and flows easily in each target country. (1)
For online stores seeking to export, translating and localizing catalogs isn’t a minor expense, but an initial strategic investment to maximize conversion rates. (2)
Below, we analyze how the translation and cultural adaptation of your online store have a direct impact on global sales, backed by empirical and market research on the digital era. (1, 6)
How does the quality of the translation impact the conversion rate of your ecommerce?
The quality of the translation has a direct impact on purchasing decisions, as 76% of consumers worldwide prefer to buy products when the information is available in their native language. (1) A literal or sloppy translation loses users’ confidence in the payment process, increasing the rate of cart abandonment. (1, 3)
With global sales projected to exceed 8.1 trillion dollars in 2026, ignoring language localization drastically limits your market share. (6) Studies confirm that 40% of users would never buy from a website that wasn’t translated into their native language. (1)
By contrast, product pages that have been accurately adapted to the language of the target market see an increase of up to 70% in conversion rates. (2) Natural-sounding language removes cognitive friction and creates that safe setting that buyers need to complete their transaction. (1, 2)
“Translating an online store isn’t just about replacing words, but transferring the reliability and values of your brand to each customer’s culture. In a demanding international market, linguistic rigor is what turns casual visits into recurring, loyal customers.”
— Carmelo Gayubo, CEO of blarlo.
What return on investment (ROI) does localizing an online store offer?
The return on investment of website localization is extraordinarily high and sustainable, returning up to 25 dollars in export revenue for every dollar invested in professionally adapting content. (2) Companies that localize their platforms in full see a significant average increase in their international turnover. (2)
This return on investment is calculated using a direct profitability ratio:
ROI = (Export revenue − Investment in localization) / Investment in localization x 100
Studies by Forrester consultancy services indicate that adopting the optimized workflows of translation and localization can generate a return on investment of 345% over three years. (4) This is because a localized website reduces the customer acquisition cost, increases repeat purchases by 53%, and drastically reduces the bounce rate on landing pages. (2, 3)
What are the best ways to successfully implement a multilingual ecommerce?
In order to ensure a multilingual ecommerce is visible on search engines and to offer a fluid purchasing experience, both the technical aspect and visual elements of the store must be adapted to the local market. (5) Correctly routing content helps search engines to index each version of the store and display these to the corresponding target audience. (5)
To ensure successful website localization, brands needs to follow these four technical and operational guidelines (5):
- Use exclusive URLs for each country or language: To ensure indexing is correct, the website needs to be structured with local domains or specific subdirectories, not by dynamically changing the language of the site using session cookies. (5)
- Adapt the currency and preferential payment methods: Consumers feel much more comfortable shopping if they see prices in their own currency and are offered payment methods that are common in their region. (5)
- Pay attention to formatting and text expansion: Depending on the target language, the translated text may expand by 20 to 30% compared to the original version, which requires a flexible website design to prevent the store interface from breaking. (5)
- Establish localized customer services: Offering a native-language shopping experience and then responding to incidents or emails in a foreign language destroys the trust you have built up during the sales process. (5)
