An industrial website should have as many languages as it has markets where a local-language route measurably changes how buyers evaluate and act, and no more than the business can keep reviewed. For most European manufacturers that lands between two and six.
The count is a capacity decision as much as a market one. Every language multiplies the technical review workload permanently, because specifications, standards references, safety wording and product availability all have to be checked again in each version every time they change. Start from where you hold commercial presence and a reviewer who knows the local terminology, and sequence the rest.
Translation is a one-off cost per page and it is rarely the reason a language programme fails. The recurring cost is technical review: someone who knows both the product and the local terminology has to confirm that a tolerance, a standard reference, a certification claim or an availability statement is correct in that market, every time it changes.
A language with no resourced reviewer will drift out of date, and an outdated specification in a buyer’s own language does more damage than an accurate page in English.
Local language matters most where the buyer is not an English-speaking specialist: maintenance engineers, installers, plant operators, procurement staff at smaller firms, and distributors selling into local tenders. It matters less where you sell to engineering departments at multinationals who already specify in English.
Test the assumption before committing. Search demand in the local language, the language your distributors quote in, and the language of incoming enquiries are three concrete signals that a market is asking for its own version.
An exporter shipping through distributors in eight countries usually needs fewer languages than its market count suggests, because the distributor carries the local conversation and may want its own material. A manufacturer selling direct into those same markets needs more.
Catalogue size raises the stakes further: translating a fifty-page corporate site is a project, translating four thousand product records with attribute values and datasheet references is a data programme, and the two should not be scoped as though they were the same thing.
Full parity across every language is seldom the right target. A common and defensible model translates navigation, corporate and capability pages, key application content and product summaries, while leaving deep technical documentation, certificates and datasheets in the language they are issued and controlled in.
Decide that boundary deliberately and state it on the site, so a visitor understands what to expect rather than meeting an untranslated page without warning.
Launching every language at once compresses translation, review and quality assurance into the same window and puts the whole date at risk. Releasing the primary language first gives local reviewers a finished reference to work against and shortens each subsequent wave.
Where markets have different search behaviour and terminology, the ordering should follow commercial priority. How the versions are targeted and kept distinct is covered on our international SEO page.
Languages can be added after launch without a rebuild where the content model was structured for it: translatable fields separated from layout, product attributes held once and rendered per language, media and documents referenced rather than duplicated, and URL and hreflang patterns defined up front.
Retrofitting translation onto a site built as a single-language brochure is disruptive and usually costs more than the original build. The structural side is set out on our multilingual industrial websites page.
As many as there are markets where a local-language route changes how buyers evaluate and act, limited by the review capacity you can sustain. Two to six is the common range for European manufacturers. The useful test is whether a named person can keep each version technically accurate indefinitely, not whether the market appears on a sales forecast.
Rarely. Every additional language at launch multiplies translation, technical review and quality assurance inside the same window, and the review step is the one that slips. Launching the primary language first gives local reviewers a finished reference and makes each subsequent wave faster. Sequence by commercial priority rather than by which translations arrive first.
Yes, where the content model was structured for multilingual support from the start: translatable fields separated from layout, product attributes stored once, and URL and hreflang patterns defined at build time. Retrofitting translation onto a site that was not designed for it is disruptive and frequently costs more than the original project.
Only where each version is maintained and correctly targeted, including local terminology and the standards a market recognises. Machine-translated pages left unreviewed, or a language that goes stale after launch, can weaken how the whole site is assessed. A smaller set of well-maintained versions outperforms a wide set that goes unmaintained.
Seldom in full. A common model translates navigation, corporate content, application pages and product summaries, while datasheets, certificates and controlled technical documents stay in the language they are issued in. Decide that boundary explicitly, signal it on the site, and make sure attribute values and units are handled consistently across every version.
The decision usually sits with marketing leadership together with the commercial owner for each region, informed by search demand, enquiry language and distributor feedback. Local sales or distribution teams matter because they see whether buyers are asking in their own language. The technical reviewer for each language should be named as part of the same decision.
