Google Ads’ AI campaign localization beta creates a separate campaign for another language or region by translating campaign assets and targeting, while offering options for handling landing-page content. Its review table lets you compare source text, localized text and an English back-translation, and edit the translation. The new campaign is published paused by default, giving you a chance to check the copy, destination, targeting, budget, bids and compliance before activation.
What the localization tool changes
Google describes AI campaign localization as a way to adapt an eligible Search campaign for another language or region. It creates a new, independent campaign; Google Ads Help says, “The original campaign is never modified.”

The tool translates campaign text and targeting, including headlines, descriptions, sitelinks, callouts and keywords. For images containing text overlays, it can remove the existing text and provide translated messaging as supplemental text assets. These changes do not establish that the offer, product availability or destination page is appropriate for the new market; those need separate review.
Choose how to handle the landing page
Google documents two approaches for landing-page localization. They solve different implementation needs, and neither should be assumed to make the destination accurate or suitable automatically.
#1 Best Overall
| Approach | How it works | What to verify |
|---|---|---|
| Dynamic translation | A Google-provided JavaScript snippet dynamically translates landing-page text when someone clicks the ad. | Check that important content is translated and remains consistent with the ad, including product details, prices and offer terms. |
| Localized URLs | Update URLs manually or use a bulk find-and-replace rule to point to localized destinations. | Test the resulting URLs and confirm each leads to the intended localized page and offer. |
Both options are part of the workflow described in Google’s localization-tool guidance. The ad translation itself does not confirm that a landing page is localized correctly.
Review translations before launch
The review table shows the original asset, its translation, a translation back into English and translation notes. You can edit translated text directly in the table. A back-translation helps you spot shifts in meaning, but Google’s documentation does not say it replaces review by someone familiar with the target language and market.
Rank #2
- Compare meaning and claims. Check product names, prices, promotions, qualifications and calls to action against the actual offer. Make sure a translation has not changed the strength or scope of a claim.
- Check market fit. Review terminology, tone and any image treatment for the intended audience. Seek appropriate local review when wording has legal or cultural consequences.
- Inspect destinations. Test each URL and any bulk replacement rule. If using dynamic translation, check that important page content is translated and does not conflict with the ad.
- Verify targeting. Check translated keywords and other targeting elements, as well as the campaign’s language and location settings.
- Review budget and bids. The tool copies these values exactly from the source campaign and does not convert currencies or calculate exchange rates. Confirm that the copied amounts make sense in the destination market and currency context.
- Check policy and legal requirements. Google warns that generated assets may not be approved. Its guidance says to check accuracy, misleading content, Google Ads policies and applicable laws before publishing. Google’s Performance Max policy guidance groups relevant requirements under prohibited content, prohibited practices, restricted content and features, and editorial and technical requirements.
- Confirm campaign and status. Ensure you are reviewing the intended new campaign, that the original remains as intended, and that the localized campaign is paused or otherwise configured as intended before launch.
Understand language coverage and eligibility
Google’s localization article describes English (US) as the supported source language. Its listed target languages are Dutch, French, French (Canada), German, Italian, Polish, Portuguese (Brazil), Portuguese (Portugal/European), Spanish (Castilian/Spain), and Spanish (Latin American and Caribbean). Google says additional target languages are planned by the end of 2026; that is a plan, not confirmation that any particular language is available now.
Recommended Free Tools
The article describes support for Search campaigns and says Performance Max support starts in September 2026. Because the feature is a beta and access can depend on eligibility and rollout, check whether it appears in your account rather than assuming availability.
The source campaign must be active or paused. Removed, draft, experimental and shadow campaigns are not supported. Campaigns must stay within entity-size limits, and their assets and keywords must use supported source language or languages. Election-verified customers are not eligible, and localization cannot proceed if a campaign contains unsupported languages. See Google’s current beta documentation for the stated eligibility conditions.

Performance Max asset generation
Performance Max generative asset creation can use a website and a product or service summary to suggest or generate headlines, descriptions, images, logos, business-name assets and video assets. It is optional: advertisers can select, edit or discard assets. Google says generated text follows the language of the entered landing page, so changing that page to one in the desired language is currently required to change the generated assets’ language in this workflow. Google cautions that generative-AI assets may be inaccurate or offensive and are not guaranteed to be approved by Ads Policy. See Google’s Performance Max asset-generation guidance.
Text customization and Final URL expansion
Performance Max text customization and Final URL expansion are campaign settings, not the separate localization flow. With Final URL expansion, Google may choose a more relevant page on the site based on a user’s search and generate matching text. Advertisers remain responsible for checking the accuracy and compliance of landing-page content and dynamically generated assets. Google documents controls for viewing or removing customized text assets and turning the feature off in its text-customization guidance and Performance Max overview.
Text guidelines
Google also documents text guidelines in beta for Performance Max and Search campaigns with AI Max. These campaign-level controls refine automatically created text; they are not a substitute for reviewing the assets that appear. Details are in Google’s text-guidelines documentation.
