Make your translated site read as local

Your translated site is live and visitors from the new market arrive; the next step is turning them into buyers. Usually the site works fine technically. What it needs is to read as local: a tone that fits, prices in the format buyers expect and a form that takes a local address, so the visitor stays with you.

Below are ten website localization fixes that get you there, grouped by where they apply.

Language and culture

Adapt to cultural differences

Each country reads content through its own culture, so check what sells in one for anything that could feel off, or offend, before it runs in the next. Culture shapes tone, colours, imagery, humour and buying behaviour. Cultural adaptation services fit the content to each audience's expectations before it goes live.

Culture Tone Colours Imagery Humour
Each of these reads differently from one country to the next, so each one gets a check before content moves to a new market.

Transcreate the message

A literal translation is grammatically correct; transcreation adapts voice, style and message to the local culture, carrying the tone, intent and local relevance that sell, and keeping the brand at full strength.

In a 2020 survey, 76% of online shoppers preferred to buy products with information in their native language, and 40% would never buy from websites in other languages.

Adjust the imagery

The right photo tells a visitor the page was made for them. Icons, gestures, dress codes and family representations vary widely between cultures.

Keep the brand voice consistent

Localize the message and keep the personality. A style guide every translator follows keeps your positioning intact in every language, the backbone of a global brand strategy.

Search and technical

Research local SEO and keywords in each language

A translated page ranks once it is built for local search. Each market has its own search behaviour, phrasing and sometimes its own preferred search engine. Multilingual SEO starts with keyword research done in the target language.

A translated page ranks once its keywords come from research in the target language, matched to how local buyers search.

Build for mobile

Some markets are mobile-first, others still lean to desktop, and a fast, uncluttered page keeps visitors in both. Make every language version responsive and fast.

Test every version

Testing finds each defect before a customer does. Test every localized version before launch: translation quality, navigation, form fields, payment gateways and speed, across browsers and devices.

Law, payments and user experience

Follow local laws

Compliance keeps you clear of fines and keeps buyers' trust. Each market has its own rules on data protection, cookie consent and ecommerce, so make sure the privacy policy, terms and checkout follow local requirements.

In 2025 the CNIL, France's data protection authority, issued 83 sanctions totalling €486,839,500 in fines, with cookies among its three main subjects alongside employee monitoring and data security.

Adapt payment methods and formats

People complete the purchase when they can pay the way they prefer, and the same goes for dates, numbers and currency shown in the format they know.

Buyers finish the purchase when the price looks familiar and they can pay the way they prefer.

Localize the user experience

Each region has its own habits, and friction shows up in the bounce rate, so watch it as closely as complaints. Localize navigation, calls to action and form fields (postcode and address formats differ too), the core of UI localization.

Start with the website localization tips closest to the sale

Website localization is a strategic investment. Start with the fixes closest to the sale (payments, forms and trust), then work outwards to search and culture.
