Quick Summary

• The short answer: Translation usually improves AI search visibility, especially for languages your site doesn't cover yet. It isn't a ranking shortcut.
• The evidence: Five studies, including Weglot's 1.3 million citations and Profound's 3.25 billion, show AI engines tend to cite content in the language of the question.
• Platforms differ: Google AI uses Google's index, ChatGPT search queries Bing, and Copilot rewarded sites with a second language most clearly.
• If you don't translate: Google may machine-translate your titles and snippets itself, and clicks can run through its translation proxy.
• Hreflang: Keep it for Google Search, but there's no public evidence it raises AI citations on its own.

Yes, translating your website usually improves AI search visibility, especially for searches in languages your site doesn't cover yet. But translation isn't a ranking shortcut. AI engines treat languages differently, and translated pages still need to be indexed, localized, and useful before they get cited.

There's also a side most guides skip. If you don't translate, Google may translate your pages for you, on its own terms.

This guide covers what the research actually shows, how each AI engine handles language, and what to translate first. It ends with how to set it up in Webflow.

At Flowtrix, our SEO and AEO team works on AI search visibility for B2B websites, including multilingual sites our Webflow development team builds.

What does the research show?

Five recent studies looked at how language affects AI citations. Each one measured something different, and each has limits worth knowing.

Finding 1, translated sites earn more AI citations:

Weglot, a website translation company, analyzed 1.3 million citations across Google AI Overviews and ChatGPT.

Translated websites saw up to 327% more visibility in AI Overviews than untranslated ones. Translated sites also earned more citations per query in both languages: 33% more in English and 16% more in Spanish.

The limit: The study only covered Spanish-language websites in Spain and Mexico. Weglot also sells translation, so treat this as one strong data point, not proof.

Finding 2, query language changes what AI engines cite:

Profound analyzed 3.25 billion AI citations across 7 AI models and 14 countries in March 2026.

Its main finding: the language of the question reshapes which sources get cited. ChatGPT's rate of citing social content dropped from about 10% in English to 3% to 5% in every non-English market studied.

Profound's own conclusion is that English-only tracking is a proxy at best and a blind spot at worst.

The limit: The study focused on content types, like social and earned media, not on translated websites specifically.

Finding 3, adding a second language helps in Copilot:

Search Engine Land compared multilingual websites with and without an English folder.

In Microsoft Copilot, sites with an English folder received 892 citations per 10,000 impressions. Sites without one received 585. That's a 52% difference.

The limit: The data comes from one analytics panel, and results differed by AI engine.

Finding 4, the same page performs differently by engine:

In a data study by WP SEO AI, a German page earned 776 Bing AI citations and just 2 Google AI impressions. Its English equivalent earned 0 Bing citations and 1,151 Google AI impressions.

Same topic, same structure, different language, opposite results.

The limit: This is one website's data, so it shows a pattern, not a rule.

Finding 5, asking in the local language changes the sources:

Academic research points the same way. One study of AI Overviews found that asking the same question in a country's official language, instead of English, raised the share of locally sourced citations by about 3.5 to 13.5 times.

Another multilingual audit found many AI citations pointed to translated pages on international websites. For Spanish queries, counting native-language pages raised the share of language-appropriate citations from 11.3% to 46.2%.

The limit: Both studies looked at health queries, not B2B software. They support the direction of the finding, not exact B2B numbers.

What the findings add up to:

AI engines tend to cite content in the language of the question. Translated pages give them that content. But the size of the effect depends on the engine, the language, and the market.

‍

What happens if you don't translate your website?

Google may translate it for you. That sounds helpful, but you lose control of the result.

Google's translated results feature kicks in when its systems find no high-quality local-language content for a query. Google then machine-translates the title and snippet of a page in another language and shows it to the searcher.

Why that's a problem for your brand:

• Your message is machine-translated. You don't review the title, the snippet, or the page.
• The visit may not reach your site. Clicks can be served through Google's translation proxy, so the searcher may never land on your actual website.
• It shows up in AI search too. Search Engine Land found translated versions appearing in AI search results, sometimes labelled "Translated by Google."
• It covers your target markets. Google added Arabic, Korean, Persian, Thai, Turkish, Urdu, Vietnamese, and Gujarati to translated results in 2024.

We've seen this on our own site. flowtrix.co is English-only. In one quarter, Google showed translated versions of our pages 3,655 times, mostly for Indian-language searches. They earned 5 clicks.

How to check if it's happening to you:

Search Console reports translated results, and you can export them by query and country through the API.

If you'd rather Google didn't translate your pages, you can opt out with a notranslate meta robots tag. A better fix for priority markets is publishing your own translated pages.

Pro Tip

Export your translated results by country before you pick your next language. The countries where Google already translates your pages most often are the markets showing demand you aren't serving yet.

‍

Do ChatGPT, Google AI Overviews, and Copilot treat translated pages the same way?

No. Each engine retrieves content differently, so translation pays off differently in each one.

Google AI Overviews and AI Mode:

Google's AI features draw on Google's own search index. To appear as a supporting link, a page must be indexed and eligible to show in Google Search with a snippet. Google says there are no additional technical requirements.

So translated pages help in Google's AI features only if they're properly indexed.

ChatGPT:

ChatGPT's web search queries the Bing index when browsing. Search Engine Land found ChatGPT leans more toward English than Google AI or Copilot, likely because it retrieves content live through an English-centered model.

That makes Bing indexing a precondition for ChatGPT citations, in every language you publish.

Microsoft Copilot:

Copilot uses Bing's multilingual index. In Search Engine Land's data, it rewarded sites with a second language the most clearly.

What this means for you:

Check your translated pages in both Google Search Console and Bing Webmaster Tools. Being indexed in one doesn't mean you're indexed in the other.

‍

Is translation enough, or do you need localization?

Translation gets your pages into the right language. Localization makes them worth citing.

AI engines look for the most useful answer, not just the right language. A word-for-word translation of a US landing page often misses what a buyer in Germany or the UAE actually needs.

Translation covers:

• The words on the page
• Page titles and meta descriptions
• Navigation and buttons

Localization adds:

• Local search terms, researched in that language
• Local proof, like customer logos and case studies from that region
• Local pricing, currency, and compliance details
• Local formality and tone

We've seen this on client work. For ZingHR, we built region and industry-specific layouts for India, MEA, and SEA.

Three myths about translation and AI search

Myth 1, translation is a ranking factor:

Fact: No AI engine has said translation itself is a ranking factor. Translated pages help because they match the language of the question. The page still has to be the best answer.

Myth 2, hreflang makes AI engines cite the right language:

Fact: Hreflang still matters for Google Search. But Google says it doesn't use hreflang or the HTML lang attribute to detect a page's language. It uses its own algorithms.

Beyond Google, there's no public evidence that AI search engines use hreflang when choosing which page to cite. Keep hreflang for Google. Don't expect it to raise AI citations on its own.

Myth 3, more translated pages means more AI visibility:

Fact: Thin, low-quality pages don't earn citations in any language. Translating 500 pages because your CMS allows it spreads your effort thin. Translating your 20 most important pages well does more.

The same rule applies to AI-written content in general. More in Is AI Content Bad for SEO?

Which pages should you translate first?

Start with the pages a buyer in that market needs to make a decision. Then expand.

1. Homepage and core product pages. These define what you do in every market. See what should be on an enterprise marketing website.
2. Pricing. Local currency and tax details matter to B2B buyers.
3. Industry or use-case pages for the sectors you sell to in that market, like our own SaaS website page.
4. Your most-cited content. Check which pages AI engines already cite in English, and translate those.
5. Demo and contact pages. A translated journey shouldn't end in an English form. For layout ideas, see these B2B landing page examples.

Leave legal pages, careers, and older blog posts until the core journey is done. Legal pages also need a qualified translator, not just AI.

‍

How do you measure AI search visibility by language?

Track each language separately. A site-wide total hides whether a new locale is working.

• Search Console by locale. Filter by your locale folder, like /de/, to see impressions and clicks per language.
• Translated results in Search Console. See where Google is still translating your English pages. Those are your content gaps.
• Bing Webmaster Tools. Confirm each locale is indexed in Bing, since ChatGPT search relies on it.
• AI referrals by landing page. In GA4, filter traffic from chatgpt.com, perplexity.ai, and other AI sources by locale folder.
• Prompt tracking per language. Ask the same buyer questions in each language every month. Record whether your brand is mentioned and which page is cited.

‍

How do you set up a multilingual site for AI search in Webflow?

Webflow Localize handles most of the technical setup. Your team handles the content quality.

Locales and URLs:

Each locale gets its own subdirectory, like /de/, and Webflow generates HTML lang tags and hreflang automatically. Localization Essential supports up to 3 locales, and Advanced supports up to 10. For full plan costs, see our Webflow pricing guide for 2026.

Translation:

Webflow's Agentic Translation, launched September 29, 2026, has two modes:

• One-time translation translates a whole language, including page content and metadata, for your team to review before it goes live.
• Continuous translation keeps a locale in sync as your primary content changes.

Keeping every locale current matters for AI search. An outdated translated page gives AI engines an outdated answer. More in What Is Webflow Agentic Translation and How Does It Work?

Consistency:

• Glossary. Keep brand and product names identical in every language, so AI engines connect them to the same company.
• Exclusion rules. Keep code, SKUs, and legal text out of AI translation.
• Localized metadata. Write SEO titles and descriptions for each locale, not just the primary one.

The bottom line

Translation expands the languages your site can answer in. Localization makes those answers useful. Technical SEO makes them discoverable. Strong content makes them citable.

If your buyers search in more than one language, publish your own translated pages for your priority markets. Otherwise, Google may translate them for you, and you won't control the result.
