What does website localisation for Europe involve? Adapting your site so buyers in a target country can understand, trust and buy without friction: translated and culturally adapted copy, local currency and payment options, region-appropriate legal and privacy pages, and a technical set-up (separate URLs and hreflang) that tells search engines which version to show. For most startups, it should be done in stages rather than all at once.

Why English-only holds you back

Many European professionals read English well, which tempts founders to skip localisation. The evidence suggests that is a costly assumption for buying decisions. In its "Can't Read, Won't Buy" consumer study, CSA Research surveyed 8,709 consumers in 29 countries and reported that:

• 76% of online shoppers prefer to buy products with information in their native language.
• 40% will never buy from websites in other languages.
• 65% prefer content in their language even if it is of poor quality.
• 75% are more likely to buy from the same brand again if customer care is in their language.
• Germany had the highest share of respondents who buy only at local-language websites, at 57%.

The study surveyed consumers, so B2B buying committees may behave differently, and it dates from 2020. Still, the direction is clear, and it matches what many teams see when they compare engagement on localised versus English pages.

Which market first?

Do not translate into five languages on day one. Choose based on evidence:

• Existing demand: traffic, sign-ups and sales enquiries by country in your analytics.
• Sales capacity: can you support customers, onboarding and invoices in that language?
• Competition: are local competitors winning because they speak the language?
• Regulatory fit: some sectors (fintech, health) have country-specific rules that affect what the site can say. Consult a compliance adviser.

For many startups, German (Germany, Austria, Switzerland) is a strong first choice given the CSA findings and market size, followed by French and Spanish. Your own data should make the final call.

What to localise first

Legal pages such as the privacy policy, terms and any German Impressum should be prepared or reviewed by a qualified lawyer for each market, not just machine-translated.

Translation versus true localisation

Good localisation changes more than words:

• Currency and pricing: show € (and CHF for Switzerland where relevant), with VAT treatment stated clearly.
• Formats: dates, decimal separators and phone numbers follow local conventions.
• Examples and proof: local integrations, regional customer stories (only real ones you have permission to use), local data-hosting options.
• Tone: formality varies. German B2B copy often uses the formal Sie; French uses vous in most business contexts. Agree this in a style guide.
• Payment methods: SEPA Direct Debit, iDEAL in the Netherlands or other local methods where your provider supports them.
• Design: German and French text often runs longer than English, so buttons and navigation need room to grow.

Machine translation followed by review from a native-speaking professional who understands your product is a practical approach for most startups. Avoid publishing unreviewed machine output on pricing, legal or security pages.

The technical set-up: URLs and hreflang

URL structure

Give each language its own URL. Subdirectories (/de/, /fr/, /es/) on your main domain are the simplest option for most startups because they share your domain's authority and are easy to maintain. Country domains (.de, .fr) can signal local presence but mean more domains to manage.

hreflang

Google's guidance on telling Google about localised versions of your page sets out the key rules:

• You can use HTML link tags, HTTP headers or an XML sitemap; Google says "the three methods are equivalent".
• Each version must list itself and every other version. Google warns: "If two pages don't both point to each other, the tags will be ignored."
• Use ISO 639-1 language codes, optionally with a region (for example de, de-AT, fr-BE). You cannot specify a country code on its own.
• Use x-default for a fallback such as a language selector page.
• Google does not use hreflang or the HTML lang attribute to detect a page's language; it relies on the content itself, so pages must genuinely be translated.

Language switching

Offer a visible language switcher that keeps visitors on the equivalent page. Be careful with forced redirects based on IP address or browser language: they can trap travellers and expats on the wrong version. Suggesting a version is kinder than forcing one.

European localisation checklist

Selling to EU consumers also brings the European Accessibility Act into scope for many digital services; our accessibility team can audit each language version.

Building and maintaining it

Most modern CMSs support multilingual sites, but the real work is keeping versions in sync as the product changes. Build a simple workflow: English changes trigger a translation task, a reviewer approves it and the pages are published together. Our outsourced web development team sets up multilingual sites and handles ongoing updates on a monthly plan, and our earlier guide to bilingual Arabic and English startup websites covers right-to-left layouts if the Gulf is also on your roadmap.
