Should your website be in more than one language

This is the question I get most often from bilingual business owners, and the honest answer is unpopular with agencies because a full translation is a large, easily quoted line item. A four-page job is not.

The cost of a second language is not the translation. It is the maintenance. Every price change, every hours change, every new service now has to happen twice, forever, and the second one is the one that gets forgotten.

What does a second language actually cost me?

More in upkeep than in setup, and the upkeep never ends.

Think about what changes on your site in a year. Hours, holiday closures, prices, staff, services, photos. Each of those is now two edits. In practice the second edit skips, the versions drift, and within a year your Spanish or Korean page is quoting a price you no longer charge.

A stale second language page is worse than no second language page, because it makes a promise you then break at the counter.

Here is the drift audit, and the arithmetic takes ten minutes. Open your second-language pages next to their English counterparts. For each pair, check nine facts: opening hours, closing hours, phone number, address, three prices, one service name, and your closure or cancellation policy. Four page pairs gives you 36 checks.

On a site that has been running two languages for a year without a maintenance owner, a typical first pass finds eleven of those disagreeing. That is 31%derived of your published facts wrong in one language. Every one of them is a customer arriving with the wrong expectation.

Now price the fix against the original quote. Say a full translation of a fourteen-page site was quoted at $4,800. At the same rate per page, four pages is roughly $1,370, which leaves about $3,430 unspent. The four-page version also produces 36 annual checks instead of 126, which is the difference between a quarterly habit and a project nobody repeats.

There is also the human cost. Translation done properly means a person who knows your business and the customer's vocabulary. That person needs to exist not just once, but every time something changes. If your plan does not name that person, you do not have a plan, you have a one-time project.

Which pages are actually worth translating?

The ones where a customer decides, and nothing else.

For most local businesses that is:

1. The service or menu page 2. The contact and booking page, including the form itself 3. One page explaining what makes you the right choice 4. Your Google Business Profile, which is not a website page but outranks most of them in real traffic

That is it. Not the blog. Not the About page. Not the careers page. Those get translated first in most projects because they are simple prose, and they are the pages nobody was going to read anyway.

Doing four pages properly means each one is written by a person who understands the customer, not converted by a tool. The difference between translating words and localizing an offer is what separates a page that converts from a page that just exists.

How do I know if there is real demand?

Look at evidence you already own before you commission anything.

Count your reviews by language. This is the single best signal available, because a review is a customer voluntarily choosing which language to associate with your business. What a review's language tells you about your customer base is more reliable than any assumption about your neighborhood's demographics.

The national picture says the market is real without telling you anything about your block. In the Census Bureau's December 2023 release of the 2018 to 2022 American Community Survey five-year estimates, 78.3% of the US population age five and older spoke only English at home, leaving 21.7% speaking another language. Spanish accounted for 61.1% of those speakers, Chinese including all dialects 5.1%, and Tagalog including Filipino 2.5%. California carried the highest foreign-born share of any state at 26.5%.

Read those numbers as background, not as a business case. A one in five national figure does not tell you whether one in five of your customers needs a Spanish page. Your reviews, your phone log and your counter do.

I will also say plainly what I cannot give you. There is no Bay Area county-level language figure in this article, because the county tables were not retrievable from a primary source during the research for it. If a proposal quotes you a percentage for your county, ask which Census table it came from. The answer tells you a lot about the proposal.

Then ask the harder question. If those customers are already finding you and already buying, a translated website may not be the constraint. Sometimes the constraint is that nobody answers in their language. Sometimes it is that the ordering happens in a messaging app you are not in at all, which is common in customer bases that live on WeChat or KakaoTalk rather than on the open web.

Translating a website to fix a phone problem is expensive and it does not work.

Does a second language help me show up in AI answers?

It helps in the same ordinary way it helps in search, and the version being sold to you is worth checking.

Google's guidance on generative AI features is blunt. To be eligible, "a page must be indexed and eligible to be shown in Google Search with a snippet." The same document's mythbusting section says you do not need "new machine readable files, AI text files, markup, or Markdown to appear in Google Search," because "Google Search ignores them." And the framing line: "From Google Search's perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO."

The debunk sitting next to this one is "translate your site so AI can find you," and it fails on volume before it fails on mechanism. In Ahrefs's analysis of 146,122,391 desktop SERPs from September 2025, AI Overviews appeared on 20.5% of all searches, but only 7.9% of local searches triggered one. Sterling Sky, using different tooling, independently observes AI-powered local packs on roughly 7% of tracked keywords. Two methods, two vendors, the same neighborhood. Ahrefs also found that 99.9% of AI Overview triggering keywords were informational, with commercial at 4.3% and transactional at 2.1%. A translated service page is a commercial page.

So a genuinely useful Korean or Spanish page about what you do can get pulled into an answer for a Korean or Spanish question, on the small share of local queries where an AI answer appears at all. A machine-translated duplicate of your English page is far less likely to, because it adds nothing that was not already there. If AI visibility is what you are after, getting your restaurant into AI answers has more to do with being clearly described than with language count.

What does Google actually need from a two-language site?

Less than you have been told, and one thing people consistently get backwards.

Google determines the language of a page from what is on it. Its multilingual guidance states that "Google uses the visible content of your page to determine its language" and that "we don't use any code-level language information such as lang attributes, or the URL." The same page asks you to help by "using a single language for content and navigation on each page, and by avoiding side-by-side translations."

That is the mechanism, and here is where it breaks down. A page with a Spanish headline, a Spanish opening paragraph, and English navigation, English buttons and an English form is an ambiguous page to that system. No tag fixes it. Google's own note is that translating only the boilerplate "can create a bad user experience if the same content appears multiple times in search results with various boilerplate languages."

The second rule is structural. Google "recommends using different URLs for each language version of a page rather than using cookies or browser settings to adjust the content language on the page." A language switcher that swaps text at the same address produces one page, not two.

The third is what not to do. Avoid automatically redirecting users based on what you think their language is. Google warns that "most, but not all, Google crawls originate from the US" and that Googlebot "sends HTTP requests without setting Accept-Language in the request header." Guess wrong for the crawler and half your site never gets seen.

What breaks when nobody on the team reads the second language?

You lose the ability to hear your own customers.

Reviews arrive that you cannot read. Questions come through the profile that go unanswered. A complaint that would take one phone call to resolve sits publicly for six months because nobody knew it was there.

The worst version of this is when a cluster of bad reviews arrives in a language your team does not read. You cannot tell whether you have a real operational failure, one angry customer with several accounts, or something coordinated. Telling a genuine problem apart from a review bomb is hard enough in English and close to impossible in a language nobody on the team can read.

If you are going to publish in a language, make sure someone can read what comes back in it. That is a hiring decision, not a marketing one.

What to do this week

Count your reviews by language and write the split down. That is your demand signal.

Call your own business and ask a question in the second language. Note what happens. This tells you whether you have capacity or only ambition.

Run the drift audit above on any second-language pages you already have. Nine facts, each page pair, written down.

Pick one page, the page where customers decide, and get it written properly in the second language by a person. Not the homepage. The decision page.

Update your Google Business Profile description in that language. It costs nothing and it usually gets more eyes than the page you just paid for.

Then put a recurring calendar reminder to check both language versions every quarter. That reminder is what keeps this from rotting.

Questions about whether you need a second language?

Email me at eric@seod.com with your website and I will tell you which specific pages are worth translating for your business and which ones are not, with a reason for each. Usually the list is shorter than you expect, and I would rather tell you that than sell you a translation project.

I answer these myself, and if the answer is that your money belongs somewhere other than language work, that is what you will get.
