Website and App Localisation
Go beyond translation. We adapt the entire user experience (UX) to your target markets. Cultural adaptation, local formatting and multilingual SEO for SaaS, e-commerce and software editors.
In 30 seconds
Asiatis localises your websites, mobile apps and digital content to adapt them to international markets. Beyond translation, we adjust formats (dates, currencies), cultural references, colours, examples and optimise local SEO. The result: a native user experience, as if the product had been designed locally.
Localisation: the art of making your product native in every market
Localisation is often confused with translation. However, they are two distinct processes. Translation converts text from one language to another. Localisation adapts the entire user experience (UX) to a local culture, market and context.
Imagine a US e-commerce site translated into French but still displaying prices in dollars, sizes in inches, dates in MM/DD/YYYY format and references to Thanksgiving. The result: the French visitor immediately perceives that the site is "foreign", which breaks trust and reduces conversions. Proper localisation would have adapted currencies (EUR), units (cm), date formats (DD/MM/YYYY) and cultural references (Christmas instead of Thanksgiving).
Since 2000, Asiatis has supported international companies (e-commerce, SaaS, gaming, software editors) in their localisation projects. Our approach covers 4 dimensions:
- Linguistic: translation adapted to the local register (France French ≠ Canadian French).
- Cultural: adaptation of images, colours, examples, references.
- Technical: date formats, currency, telephone numbers, units of measurement.
- Local SEO: optimisation for local search engines (Google.fr, Google.de, Baidu, Yandex).
1. Linguistic adaptation: beyond word-for-word translation
A literal translation of a site or app creates sentences that are technically correct but culturally strange. For example, the American slogan "Think different" (Apple) does not work in French if translated literally ("Penser différent"). The official French version is "Pensez différemment", but even this translation loses the impact of the original.
We apply contextual translation:
- Adapted tone: formal in German, informal in US English, polite and indirect in Japanese.
- Localised idioms: "raining cats and dogs" → "il pleut des cordes" (French).
- Text length: German is 30% longer than English, Chinese 50% shorter → UX adjustments.
- Regional variants: France French vs Quebec French, Spain Spanish vs Mexican Spanish, Brazilian Portuguese vs Portugal Portuguese.
2. Cultural adaptation: images, colours, references
Certain visual or textual elements work in one culture but fail in another:
Real example: A US healthcare site used a thumbs up image (👍) to mean "approved". In Iraq and Iran, this gesture is offensive. The image was replaced with a green tick (✓) for Middle Eastern markets.
Our native translators identify these cultural sensitivities and recommend adaptations:
- Colours: white = purity in the West, mourning in Asia. Red = danger in the West, prosperity in China.
- Symbols: avoid religious references in certain markets (cross, star, etc.).
- Characters: ethnic diversity adapted to the market (Asian models for China, etc.).
- Examples: replace "Super Bowl" with "World Cup" for Europe, "Black Friday" with "Singles Day" for China.
3. Technical adaptation: formats, currencies, units
Technical details are crucial to avoid confusion:
Date formats
USA: MM/DD/YYYY (12/25/2025) • Europe: DD/MM/YYYY (25/12/2025) • China/Japan: YYYY/MM/DD
Currencies & Pricing
Conversion + local symbol (€, £, ¥, $) • Symbol position (before/after) • Decimal separator (. or ,)
Telephone numbers
International format (+33, +1, +86) • Local area codes • Local toll-free numbers
Units of measurement
Metric (km, kg, °C) vs Imperial (miles, lbs, °F) • Clothing sizes (EU vs US vs UK)
4. Multilingual SEO: local visibility on Google
Localising a site without optimising local SEO makes it invisible. Our multilingual SEO specialists apply best practices:
- Native keyword research: no literal translation of your source keywords. Our native SEO specialists identify the queries actually used by local users, with volumes and CPC, using Ahrefs, SEMrush, Google Keyword Planner and Baidu Keyword Tool.
- hreflang tags: indicate to Google which version of the site to display depending on the user's language/region (avoids duplicate content).
- Localised URLs: `/en/services` vs `/fr/services` vs `/de/dienstleistungen` (translated slug).
- Adapted meta tags: titles and descriptions transcreated (not simply translated) for local queries.
- Local backlinks: partnerships with local sites to strengthen regional authority.
Result: your site appears on the first page of Google.fr, Google.de, Google.co.jp, Baidu (China), Naver (South Korea) and Yandex (Russia), with content adapted to each market.
Formats and platforms: sites, apps, software, games
We localise all types of digital content:
- Websites: CMS (WordPress, Drupal, Joomla), static (HTML/CSS), frameworks (React, Vue, Angular).
- Mobile applications: iOS (.strings files), Android (strings.xml), React Native, Flutter.

We deliver localised files in the source format (JSON, XML, XLIFF, etc.) for direct integration into your platform.
Localisation process: from analysis to validation
- Project analysis: target languages, priority markets, technical formats, volume.
- Content extraction: source files (JSON, XML, CMS export).
- Glossary + style guide: creation of a terminology glossary and tone guide per language.
- Translation + cultural adaptation: by specialised native translators.
- Technical integration: reinsertion into source files, format testing (dates, currencies).
- Linguistic testing: display verification (text length, special characters, RTL for Arabic).
- Final validation: quality control + functional testing.
