Multilingual website: when it's worth it and what really changes

"Should my site be in English too?" It's a question I hear often, usually right after everything else about the site has already been decided, almost as an obvious add-on. It isn't: adding a language changes the project more than it looks from the outside, not so much at the start as over the site's entire life.

Who it's actually for, and who it isn't

A multilingual website makes sense when there already is, or you genuinely want to build, an audience that doesn't speak your main language: foreign clients who arrive through referrals or trade shows, an overseas market you want to sell into, international guests if you run a hospitality business. That last case is different from every other industry: for a hotel or other accommodation, going multilingual isn't a choice, it's the baseline, and I've written about that in more detail elsewhere.

For everyone else, the right question isn't "could this help" but "are inquiries, contacts, or searches already coming in another language". If the answer is no, and there's no concrete plan to change that, a second language adds work without adding almost anyone who will read it.

An online shop that already ships abroad, a professional practice with international clients, a company that exports: these are cases where a foreign audience isn't a hypothesis, it already exists, and the website is the one place where that audience still can't find its own language, when it finds it everywhere else, from the invoice to the phone call.

A signal worth checking before deciding

Before adding a language, it's worth looking at what's already happening rather than guessing at it. Messages that arrive in another language through the contact form or by email, orders shipped outside the country, quote requests coming from a foreign phone number: these are concrete signals, and they say more than a hunch about how much it's actually worth investing. If none of these signals exist yet, the problem to solve is finding that audience, not translating a site no one abroad is looking for yet.

What really changes, and it doesn't end with translation

The cost you notice right away is translating what the site already has. What you don't notice, and what weighs more over time, is that from that point on every page exists twice, not once: a new service, an updated price, a blog post, even a simple change of hours have to be written and updated in every active language. If one language doesn't get the same update as the other, the site starts telling two different versions of the same business, and whoever notices, a customer comparing the two pages, or simply Google indexing both, reads it as a site left half finished, not as a minor detail.

The number that actually matters here

This isn't just a matter of convenience for the reader. CSA Research, a research firm specializing in language services, measured in 2020, on a sample of 8,709 consumers across 29 countries, that 76% prefer to buy when information is available in their own language, and 40% say they never buy from a website in a language other than their own. It's global data and it's six years old, not a study of any single country and not a picture of today, but the mechanism it describes, people who can't find their own language hesitate or give up, remains the underlying reason multilingual sites matter when a foreign audience genuinely exists.

How many languages, not all of them

From this follows a practical choice: the languages worth activating are the ones spoken by people who already write to you or already buy from you, not a list as long as the flags on a map. Two well-maintained languages are worth more than five left behind after the first update. If it isn't clear where inquiries in another language actually come from, it's worth checking the site's own analytics before deciding by eye.

What the cost depends on

How much it costs to make a site multilingual depends on three things: how many languages, how many pages, and whether plain translation is enough or the final text also needs professional review. There's no fixed figure, which is why it's assessed case by case: get in touch and tell me who your site speaks to today, and in which language the inquiries you can't fully answer are already arriving.
