Google Drops Language Targeting in Search Campaigns

Google Ads is retiring campaign-level language targeting for Search campaigns and Search inventory within Performance Max, a shift that hands more control to automated signals. The rollout begins in late September, and it marks a notable change in how multilingual eligibility will be determined across the platform.

For advertisers, this raises practical questions about campaign structure, multilingual reach, and whether specialized uses of language settings will still hold up. Here is a breakdown of what is changing, how Google says the new system will work, and where uncertainty remains.

What Is Changing With Language Targeting

Currently, Google combines campaign settings with its own language signals to decide whether a Search ad can serve. Advertisers pick one or more languages at the campaign level, while Google separately assesses which languages a user understands, using clues like query language, user preferences, and AI-derived signals. Google also checks whether the user can comprehend the ad and landing page language.

Starting in late September, the campaign-level language setting will disappear for Search and AI Max for Search campaigns. Google will instead lean on the language of the creative and landing page, paired with its existing understanding of user languages.

Performance Max campaigns see a similar adjustment for Google Search. Campaign-level language will no longer apply there, and matching will work the same way as Search campaigns. For other channels within Performance Max, the campaign-level language setting remains in effect.

How Google Prioritizes Multiple Languages

When a user understands more than one language, things get more nuanced. If Google determines someone knows both English and Spanish, for example, ads in either language could qualify. Google’s enhanced AI-based ad group prioritization then decides which language fits the search better.

When the query itself signals a clear language, Google will favor an ad and landing page in that language, provided an eligible option exists.

Brand searches complicate this. A brand name might look identical across languages, giving Google little linguistic signal from the query alone. In those cases, Google says it will fall back on other language signals and prioritize the user’s preferred language. For someone who regularly searches in both English and Spanish, ads in either language could now become eligible.

Google also argues this change reduces setups that unintentionally block relevant traffic. A campaign targeting one language but containing ads or landing pages in another could previously exclude users even when Google believed they understood the ad. That restriction now lifts.

Advertisers using the Google Ads API need to adjust as well. Google recommends developers stop sending language criteria when creating or updating Search campaigns. Existing language criteria can stay, but they will no longer influence Search targeting.

Google insists advertisers don’t need to restructure existing campaigns. Accounts that split English, Spanish, or other languages into separate campaigns can keep that setup, with Google using creative and landing-page languages as matching signals.

That covers the common uses of language targeting. More specialized applications, however, remain less settled.

Advertisers Raise Questions About Nuanced Use Cases

Google says the update will support nearly all current language targeting use cases. During a virtual roundtable I joined ahead of the announcement, advertisers pressed Google on how the change would play out in trickier scenarios.

Several questions centered on situations where language settings serve purposes beyond matching ads to users who understand them.

Regulated Advertisers Question How To Document Delivery

In the roundtable, advertisers in regulated industries raised compliance concerns. An insurance advertiser, for instance, might need to show that ads are available equitably across English- and Spanish-speaking audiences.

Google responded that providing ads in both languages signals intent to reach both groups. Its systems then determine which users understand each language and select an eligible ad accordingly.

But the roundtable question went deeper than intent. Advertisers wanted to know how they could prove ad delivery when Google, not the campaign setting, decides language eligibility per user.

That answer remains open. Google did not announce additional language reporting that would show which languages were served or how performance differed by language. That visibility could prove critical for advertisers needing to document delivery decisions for regulatory or internal compliance.

AI Max Creates Another Multilingual Scenario

Advertisers also asked how the change interacts with AI Max and automatically generated creative.

One example involved an AI Max campaign targeting Quebec. If asset generation produces French creative based on the advertiser’s inputs and other campaign signals, could that French ad serve when a user searches in English?

Google confirmed it could. Creative generation happens first. Then Google applies its language comprehension checks to determine whether the user understands the available ad and landing page.

The query language doesn’t have to match the ad language. An English search could trigger a French ad when Google determines the user understands French and its prioritization system selects that creative.

Google’s responses clarified how its systems will handle these language decisions. The roundtable also highlighted where advertisers currently rely on the campaign setting for controls or documentation that automated matching doesn’t directly replace.

What This Means For Advertisers

For most advertisers, this update shouldn’t require major changes. Google says existing campaigns don’t need restructuring, including accounts that separate campaigns by language. There’s no reason to merge those campaigns just because the language setting is leaving Search.

The accounts that deserve closer review are those using language targeting for more than its primary purpose. Travel, international, and regulated advertisers should understand what role the setting currently plays. If it helps control audience eligibility or supports compliance requirements, its removal could have a more noticeable impact.

For everyone else, focus on the basics. Ensure ads and landing pages use the intended languages, especially in multilingual campaigns and those using AI-generated assets.

After the rollout, monitor performance before making broader adjustments. International and multilingual advertisers should pay particular attention to search terms, geographic traffic, and any shifts in who appears to be entering their campaigns.

What To Watch After The Rollout

Google emphasized during the roundtable that removing the campaign-level setting shouldn’t fundamentally change how language matching behaves today. As Google put it, “the way things are behaving now aren’t changing.”

Still, advertisers should watch whether traffic patterns shift once Google relies solely on its own language signals without the extra campaign-level setting. That includes unexpected changes in search terms, geographic traffic, or the languages associated with incoming users.

If performance and audience composition stay relatively consistent, Google’s argument that the setting was largely redundant gains credibility. The less conventional use cases may take longer to resolve, particularly where advertisers previously used the setting as an extra layer of audience control.
