Google Is Removing Language Targeting From Search Ads

Google’s language targeting help page now carries a dated note: “Starting in September 2026, the way that language targeting works is changing for Search campaigns and the Search Network portion of Performance Max campaigns.” For Search campaigns the campaign-level language setting is removed and ads match on the language of the ads themselves. For Performance Max the setting stops applying to the Search Network but still governs YouTube, Display, Discover and Gmail.

Google says no action is required. That is true in the sense that nothing breaks. It is not true for an account that used the campaign setting to keep languages apart, because that job now falls to the ads and landing pages, and an account that wrote ads in one language for a landing page in another will behave differently. This post records what the page says, how matching works without the setting, and what to check in a multilingual account this month.

The note is short and the table below is its whole content, campaign type by campaign type. Everything else on the page describes how Google detects language on each network, which was true before the change and remains the mechanism after it.

One consequence follows directly. A single Performance Max campaign can now behave two ways at once: constrained by its language setting on YouTube and Display, unconstrained on Search. Anyone reading channel-level reports for a multilingual Performance Max campaign should expect the Search rows to widen and the other rows to stay put.

The same page explains what Google looks at on the Search Network: the language of the search term and the user’s language settings and preferences, to work out which languages the person knows, and then tries to serve the best ad it has in one of them. Google’s own example is a user whose browser is set to Spanish but who searches in English too, and who may see ads in either language, or a Spanish query answered by an English ad.

The page adds that AI-based ad group prioritisation will make sure ad candidates in the most relevant language for the user come first. That prioritisation is Google’s existing system for choosing which ad group enters the auction when several could match a search term; its help page describes relevance as a function of the search term’s meaning, the keywords in the ad group, and the ad group’s landing pages. Read together, the two pages say the language decision now happens at ad-group level, using the ad and the landing page as evidence.

An account that runs one language in one market will notice nothing. The change matters where the campaign setting was doing work that the creative did not, and three account shapes fit that description.

The first is a multilingual market with one campaign per language, where the setting stopped an English campaign serving to a French-preferring user even when the keywords matched. That separation now depends on the ads being unmistakably in one language and the landing pages agreeing. The second is an account whose ads are written in one language while the landing page is in another, common where a local team writes copy for a global site; Google’s prioritisation reads the landing page, so the two now pull in different directions. The third is a Performance Max campaign built for one language that will, on Search, be judged on its assets rather than its setting.

Each check follows from what the help page says the new mechanism reads. None of them predicts a performance effect, because Google has published no data on one and neither has anyone else.

The same discipline applies to the site behind the ads. If landing pages are the evidence of language, then language-specific pages with correct language tags matter more than they did, which is the subject of our international SEO and hreflang guide. For the campaign type itself, our Performance Max guide covers asset-group structure.

The page gives no day within September, no rollout order by account or region, and no statement of whether the setting disappears from the interface at once or stops applying first. It gives no before-and-after data and no expected effect on impressions, clicks or cost. It does not say what happens to a campaign whose ads are in two languages. Anything more specific than the table in section one is an inference or a report, and this post has tried to keep the two apart.

Our paid media practice runs the creative and landing-page audit above as a fixed-scope piece of work for multilingual accounts, and will update this page if Google adds a date or a detail.
