Google Ads localization: AI translates whole Search campaigns - but the budget does not convert

Search Engine Roundtable reported the tool on October 5, 2026. Barry Schwartz, the site's executive editor, wrote that he found a new Google Ads help document late last week. It describes an "AI campaign localization tool" for Search campaigns, labelled beta. This matters to anyone who pays for Google ads and has customers who would rather read in another language. Work that used to mean hiring a translator and rebuilding a campaign by hand is now a menu option inside the account.

Google's tool rebuilds an English campaign in another language

Google's own help document says the tool can "quickly localize entire Search campaigns for new languages and regions using generative AI." Instead of "waiting extended periods for manual translation and spreadsheet uploads," it says, advertisers can translate text, images, targeting and landing pages "with a few clicks."

According to Google, localizing a campaign creates a brand new, independent campaign, and the original campaign is never modified. The help document lists what gets translated: headlines, descriptions, sitelinks, callouts and keywords. Images are handled differently. If an image has text laid over it, the AI removes that text, which Google calls in-painting, and adds the translated words as separate text assets.

Think of it like photocopying a filing drawer into a second drawer and translating every folder on the way. The first drawer stays exactly as it was. By default, the second one stays closed until you decide to open it.

French (Canada) is on the list, and English must come first

Google's help document says the tool works on campaigns whose original source language is English (US). The target languages listed are Dutch, French, French (Canada), German, Italian, Polish, Portuguese (Brazil), Portuguese (Portugal/European), Spanish (Castilian/Spain) and Spanish (Latin American & Caribbean). The same document says more target languages will be added by the end of 2026, and that the tool will support Performance Max campaigns starting September 2026.

For a business owner in Canada with French-speaking customers, French (Canada) is the line to notice. A clinic or trades company that already runs English search ads could build a French (Canada) version without starting from a blank page. Google names this use directly. The help document says the feature can help "reach new customers who speak different languages within your existing markets," not only customers abroad.

There are conditions, according to Google. The original campaign must be active or paused. Removed, draft, experimental or shadow campaigns are not supported. The campaign must stay within entity size limits. Every asset and keyword must be in a supported source language, and a campaign that mixes in an unsupported language cannot be localized.

You can check the translation without speaking the language

Google says there are three ways in. You can tick a campaign in the Campaigns table and choose the localization option, or pick Localization from the Tools menu. You can also apply what Google calls an Optiscore localization recommendation, which appears when Google Ads sees a chance to improve performance through localization.

The review step is built for people who do not read the target language. The help document says the review table shows each original asset, the translated asset, a "translation back" into English so you can verify the meaning, and translation notes, and that you can edit any translated text directly. Before the translation runs, you can add free-form instructions. Google's examples are "Do not translate the brand name" and "Keep the tone formal."

According to the help document, a finished campaign is published in a "Paused" state by default, so it does not go live until someone switches it on. That default is your safety catch, so use it.

The budget copies over, but the currency does not

This is the detail most likely to cost someone money. Google's help document says budgets and bids are copied exactly from the original campaign, with no currency conversion or exchange rate calculation, so a $100 USD budget becomes a $100 USD budget in the localized campaign. The setup step does ask you to set the new campaign's location and budget, so you can change the number. If you leave it alone, the new campaign spends like the old one, whether or not the new audience is worth the same.

Google's documentation gives three options for landing pages. You can paste a Google code snippet on your website that translates the page text as it loads when someone clicks the ad. You can use a bulk find-and-replace rule to point ads at pages you have already translated, for example changing example.com/en to example.com/fr. Or you can leave the URLs as they are. The help document describes a review table for the ad text, but it does not describe any review step for the landing page text the snippet translates.

The same day, another Google Ads change switches on automatically

The localization tool is something you choose to use. Not every Google Ads change works that way. Search Engine Roundtable reported the same morning that Google emailed some advertisers about a change starting October 12, 2026. From that date, Google Ads will automatically find promotions such as coupons and deals on their websites and apply them to their campaigns. Schwartz wrote that Arpan Banerjee sent him the email.

According to that email, the change applies only to Search and Performance Max campaigns with linked location assets that do not already have promotion assets attached. Search Engine Roundtable reported that automated promotions is opt out, and that you turn it off in the account-level automated assets settings by setting Automated Promotions to Off.

On the organic search side, Google's message this week was a warning about volume. Google's Search Central blog says Search Central Live Deep Dive Europe ran in Barcelona from September 30 to October 2, 2026. Search Engine Roundtable quoted John Campbell's recap of the event. In it, Campbell says Gary Illyes warned that scaled content is becoming more of a problem than link spam, and he sums up: "Scaled, low-effort content is the risk." That was said about Google Search, not ads. Google's localization help document does not say how its translated landing pages relate to search rankings. The lesson still carries over, though: producing text in a new language is now fast, and fast is not the same as good.

Google has left several questions unanswered so far

The other side: Google's help document does not give a price or say whether the tool costs anything beyond normal ad spend. It offers no figures on translation accuracy or on how localized campaigns perform, and it labels the tool beta. It requires English (US) as the source language and does not say whether campaigns written with Canadian spelling qualify. The Performance Max date it gives, September 2026, has already passed, and the document does not confirm whether that support has arrived. According to Google, election-verified customers cannot use the tool at all. Finally, the landing page snippet translates your website automatically, and the document does not say who checks that wording, whether it is a clinic's aftercare instructions or a contractor's warranty terms.

Bottom line

According to its own help document, Google has turned translating a Search campaign from a project into a few clicks. For a business with customers who speak French, Spanish or Portuguese, that makes trying much cheaper. It does not make mistakes any cheaper. The budget copies over blindly, and Google's document describes no review step for the landing page translation.

If you try it, publish paused and read every translation-back line. Set the budget for the new market on purpose, and have a fluent speaker read the landing page before you switch the campaign on. Which of your customers are searching in a language your ads do not speak yet?
