How to Translate Google Ads: A Step-by-Step Guide for Multilingual Campaigns

To translate Google Ads well, you need more than a translated copy of your English ad. You need keywords people in each market actually search for, headlines that fit Google’s character limits in the new language, an offer that makes sense locally, and a landing page in the same language as the ad.

It’s worth the effort. In a survey of 8,709 consumers in 29 countries by CSA Research, 65% said they prefer content in their own language, even if the quality is poor, and 40% said they won’t buy from websites in other languages. A Search Engine Journal experiment also found higher click-through rates on ads written in the searcher’s language.

Google Ads won’t translate your search ads for you. It shows the ad you wrote to people who understand its language. This guide walks through the seven steps, with examples in Spanish, French, and German.

Step 1: Choose languages, not just countries

Start with who you want to reach and what language they search in. Canada needs English and French; Belgium needs French and Dutch; the US often needs Spanish as well as English.

Google decides who sees your ad by language signals: the language of the search, the user’s language settings and, on the Display Network, the language of the pages they visit. From September 2026, Google removes the campaign language setting for Search and matches Search ads by the language of the ad text and the landing page instead. In practice, a Spanish ad that sends people to an English page now sends Google a mixed signal, so translate both.

Step 2: Research keywords in each language

Don’t translate your English keyword list. People in another market often use different words for the same thing, and the literal translation can have far fewer searches, or none at all.

Ask a native speaker to brainstorm how locals would search, then check each term in Google Keyword Planner with the right location and language. Google also matches close variants, including common misspellings, so a native speaker should review the search terms report and add negatives for matches that don’t fit.

Step 3: Build one campaign or ad group per language

Keep each language in its own campaign, or at least its own ad group, with its own keywords, ads and budget. Mixing languages makes it impossible to see which market is working and lets a weak language drain the budget of a strong one.

Step 4: Write to Google’s character limits

Responsive search ads take up to 15 headlines and 4 descriptions. Google’s limits are the same in every language:

Field	Limit
Headline	30 characters
Description	90 characters
Display URL path (each of 2)	15 characters

Two things make translated ads harder to fit:

• Many languages run longer than English. Spanish, French, and German often need more words for the same idea, and Arabic spells out phrases that English shortens with a hyphen, such as “three-book series”.
• Double-width characters count twice. Every Chinese, Japanese, or Korean character uses two of the 30 slots, so a headline has room for about 15 characters.

The fix is to rewrite, not cut. Here’s one English headline translated literally and then adapted to fit:

Language	Literal translation	Characters	Adapted headline	Characters
English	Free Shipping on All Orders	27	—	—
Spanish	Envío gratuito en todos los pedidos	35	Envío gratis en cada pedido	27
French	Livraison gratuite sur toutes les commandes	43	Livraison offerte sur tout	26
German	Kostenloser Versand für alle Bestellungen	41	Versandkostenfrei bestellen	27

Each adapted version is what a local shopper would expect to read, not just a shorter one.

Step 5: Adapt the offer, not just the words

A translated ad still has to make sense to a local buyer. Prices go in local currency, free-shipping thresholds match local order sizes, and seasonal hooks follow the local calendar: a November sale in Mexico is promoted around El Buen Fin, not only Black Friday.

The same language also changes by country. “Spanish in Spain will differ from Spanish in Mexico,” as Search Engine Journal notes, so write separate ads when you target both. This is where translation becomes transcreation: the ad keeps its goal, but the words are rewritten for the market.

Step 6: Send clicks to a page in the same language

A French ad that opens an English page loses most of the people you just paid for. In the CSA Research survey above, 40% of consumers said they won’t buy from websites in other languages. And on Search, Google now uses the landing page language to match your ads, too.

At minimum, translate the landing page each campaign points to. For a store, that means product pages, prices, shipping and returns; e-commerce translation and website translation cover the rest.

Step 7: Add negative keywords and test each language

Check the search terms report for each language every week in the first month. Native speakers spot irrelevant matches that a non-speaker would miss, and each one becomes a negative keyword.

Then judge each language on its own numbers: click-through rate, conversion rate, and cost per conversion. Give each ad group several headline options so Google can test them, and replace the weakest after a few weeks of data.

Can you use Google Translate or AI to translate your ads?

You can use it for a first draft of a long description, but not for the ad you publish. Machine translation doesn’t know your character limits, picks the most literal word rather than the one people search for, and can’t judge tone. A native speaker should rewrite every headline and check every keyword before the ad goes live.

When to use a Google Ads translation service

If you run ads in more than one or two languages, or the budget is large enough that a weak ad is expensive, a professional Google Ads translation service pays for itself. At TranslationPartner, native linguists research keywords in each market, write headlines and descriptions to Google’s limits, and return your ad export ready to upload. The same approach works for social media ads.

Checklist: before you launch a translated campaign

• Keywords researched in the target language, not translated
• One campaign or ad group per language
• Every headline 30 characters or less, every description 90 or less (double-width characters count twice)
• Offer, currency, and dates adapted to the market
• Landing page in the same language as the ad
• Negative keywords reviewed by a native speaker
• Results tracked per language

FAQ

Does Google Ads translate ads automatically?

Not your search ads. Google shows the ad you wrote to people who understand its language, so to reach people in another language, you need ads written in that language.

Should I use one campaign for several languages?

It’s better not to. Separate campaigns or ad groups per language let you set budgets, keywords, and bids for each market and see which one performs.

Do I need to translate the landing page too?

Yes. People are far less likely to buy on a page they can’t read, and on Search, Google uses the landing page language to match your ads.
