Translation vs Localisation
Translation changes the language. Localisation changes whether the content actually works commercially in that market. Confusing the two is one of the most common and costly market entry mistakes.
In short
Translation converts text from one language to another while preserving its original meaning; localisation adapts content — language, examples, proof points, currency, units, compliance references and tone — so it functions naturally and persuasively for a specific market's buyers. Translation is necessary everywhere international content appears; localisation is what actually makes that content commercially effective, and is worth prioritising for the pages that carry the most weight in the buying decision, such as home pages, product pages and case studies.
Translation and localisation get used interchangeably in most conversations about international expansion, but they are different pieces of work with different cost, different skill requirements and, most importantly, different commercial outcomes. A translated site reads correctly in the target language. A localised site reads as though it was written for that market — its examples, proof points, pricing presentation, units, compliance references and even the questions it chooses to answer are adapted to how that market actually buys.
Most companies need some of both, and the mistake is rarely choosing translation over localisation deliberately — it is defaulting to translation because it is cheaper and faster, without recognising which parts of the site actually need the deeper work.
Two definitions, side by side
- Translation
- Converting written or spoken content from a source language into a target language while preserving its original meaning as closely as possible. Good translation is accurate and fluent, but it does not change what is being said or how it is framed for a different audience.
- Localisation
- Adapting content — language, tone, examples, proof points, currency, units of measurement, regulatory or compliance references, imagery and structure — so it reads as though it was created for that specific market, not adapted from another one. Localisation includes translation but goes well beyond it into commercial and cultural adaptation.
Why the difference matters commercially
A page that is accurately translated but not localised often still fails to convert, because it answers the home market's implicit questions rather than the target market's. A UK company's case study referencing UK regulations, UK customer names a German buyer has never heard of, and pricing in pounds, does not become effective for Germany simply by being rendered fluently in German — a German buyer still has to do the mental work of translating the relevance themselves, and most will not bother.
Direct comparison
| Factor | Translation | Localisation |
|---|---|---|
| What changes | Language only | Language, examples, proof points, currency, units, tone, compliance references |
| Cost | Lower | Higher — requires market knowledge, not just language skill |
| Who can do it | A qualified translator | A translator with genuine market and commercial knowledge, or a local reviewer |
| Effect on conversion | Makes content readable in-market | Makes content persuasive and relevant in-market |
| Where it is essential | All international content, as a baseline | High-stakes pages: home page, product pages, case studies, pricing |
Not every page needs full localisation
It is neither necessary nor affordable to fully localise every page on a site for every market. A sensible approach prioritises localisation for the pages that carry the most commercial weight in a buying decision — the home page, core product or service pages, case studies and pricing information — while accepting well-translated content for lower-stakes pages such as terms, policies or general background information, where fluent, accurate translation is sufficient.
Common signs that a site is translated but not localised
- Case studies or proof points reference customers or contexts the local market has no reason to recognise
- Currency, units of measurement or date formats are left in the source market's convention
- Compliance or standards references are specific to the home market with no local equivalent mentioned
- The tone and structure clearly mirror the source-language site rather than how local competitors present themselves
- Search terms and headings reflect how the home market phrases things rather than how the local market actually searches
Localisation and AI or traditional search performance
Localised content also tends to perform better in both traditional and AI-driven search, because it answers the specific questions that local buyers actually search for, rather than a direct rendering of home-market questions. This connects directly to the discipline covered in more detail elsewhere on market-level answerability for AI search.
A practical approach
- Translate everything that needs to exist in the local language, as a baseline
- Identify the highest-stakes pages in the buying journey and localise those properly, with market-specific examples and proof
- Convert currency, units and date formats correctly for the target market throughout
- Have a local-market reviewer, not just a translator, check tone and relevance before publishing
- Revisit localisation as the market matures, rather than treating the first pass as final
