Campaign translation tool in Google Ads: advantages, limits and care with European Portuguese

What was reported

PPC News Feed reported that Google Ads now includes a campaign translation tool, with a help page published in early October 2026. According to the report, it translates ad texts (headlines and descriptions), targeting keywords, images (AI replaces the text in the image and adds translated versions) and landing pages. For pages, the advertiser can upload URLs manually or install a JavaScript snippet.

The report cites Jyll Saskin Gales, who highlighted public availability of a tool that before existed only on request.

What the report doesn't say

It doesn’t state supported languages, campaign types, detailed usage steps or limitations. A related article from the same publication links to an AI localisation tool for Search campaigns, but the report itself doesn’t clarify.

So, if your company sells or wants to sell outside Portugal, the first task is to check in your account whether the tool is available, which languages it offers and whether it distinguishes European Portuguese from Brazilian Portuguese.

Who gains from the tool

Portuguese companies that export (tourism, e-commerce, software, industry), that sell in Spain, France or the UK, or that have foreign customers in Portugal (expats, tourists, digital nomads). Automatic campaign translation reduces start-up time and lets you test markets at lower cost.

For the purely domestic market, the gain is smaller, but there may be cases: a clinic or local accommodation that wants to attract English-speaking customers.

Translation is not localisation

Translating an ad word for word is rarely enough. Localisation adjusts tone, examples, currencies, date and address formats, cultural references and the search expressions people use in that country. A correct translation can be a terrible search: nobody searches those words.

Translated targeting keywords should be validated with target-market data (volume, intent) and, preferably, by a native speaker.

A correct translation can be a terrible search: nobody searches those words.

European Portuguese versus Brazilian Portuguese

If you advertise from a source language into Portuguese, or use the tool to create a Portuguese version, confirm the result is European Portuguese: “telemóvel” not “celular”, “autocarro” not “ônibus”, “casa de banho” not “banheiro”, “equipa” not “time”, “pequeno-almoço” not “café da manhã”. A Brazilian variant in an ad for Portugal sounds foreign and reduces trust.

Ask for review by someone who writes European Portuguese before activating. It’s a check of minutes.

Images with AI-translated text

The report says the AI replaces text in images and adds translated versions. This requires review: typography, line breaks, currency symbols, prices, legal notices and references to promotions. In an ad with a price, a format error can mislead the consumer.

In sectors with mandatory notices (health, finance, credit, gambling), legal text has to be exact and complete in the ad’s language. Don’t leave that text to automatic translation without legal validation.

Translated landing pages: SEO and conversion

A JavaScript snippet that translates the page on the fly may work for testing, but may affect speed, indexing and experience. For a serious market, a page translated and reviewed by humans, with the language indicated (hreflang), local prices, payment methods and local contacts, converts better.

If you want to test a new market, use automatic translation to start, but plan the professional version if there are signs of demand.

A test plan for a new market

Step 1: choose a market and an offer. Step 2: translate a small campaign and validate keywords and ads with a native speaker. Step 3: define budget and metric (cost per qualified lead). Step 4: run for 4 to 6 weeks. Step 5: decide to expand, adjust or stop.

If budget is small, focus on one market. Spreading across several only generates insufficient data in all.

Questions for your manager

Is the tool available in our account? Which languages does it offer? Does it distinguish European from Brazilian Portuguese? Who reviews the translations? How do we validate keywords per market? And what metric decides whether the new market pays off?
