Google is removing the campaign level language setting from Search campaigns and from AI Max for Search campaigns starting in late September 2026. Search Engine Land reported the change on 13 August 2026, and once it lands, Google decides who sees an ad from the language of the ad creative and the landing page, plus what Google already understands about which languages a user knows.
Nothing replaces the setting. There is no new field to fill in and no migrated equivalent. The list of languages an advertiser used to pick in campaign settings simply stops feeding the matching system, and the words in the ad and the words on the page take over the job.
What Google is changing in late September 2026
Starting in late September 2026, Search campaigns and AI Max for Search campaigns lose the campaign level language setting, according to the Search Engine Land report by Anu Adegbola published on 13 August 2026. Search Engine Journal, in reporting by Brooke Osmundson, covered the same change on the same day, which is worth noting because two independent write-ups of a Google Ads settings removal on the same date usually means the information came from Google rather than from a single account observation.
The framing matters. This is not a redesign of language targeting and it is not a new control with a different name. It is a removal. The panel loses a field, and the logic that field used to drive moves inside Google's automated matching.
You can read the original report from Search Engine Land in its coverage of the language targeting removal, which is where the late September 2026 date comes from.
How Google will decide language once the setting is gone
After the removal, Google matches ads to users using three inputs named in the Search Engine Land report: the language of the ad creative, the language of the landing page, and Google's existing understanding of which languages a given user knows. That third input is not new. Google has always layered its own read of a user's language onto whatever the advertiser declared. What changes is that the advertiser's declaration is no longer part of the equation.
Read plainly, the mechanism inverts where the control sits. Under the old model, an advertiser could run an English ad group and tell Google to serve it only to people whose interface language was English, even if the ad copy itself was ambiguous. Under the new model, the ad copy is the declaration. If the creative is written in Thai and the landing page is Thai, that is a Thai ad. If the creative is written in English and points at an English page, that is an English ad. A campaign that mixes English headlines with a Thai landing page is sending Google two different answers, and Google resolves the conflict on its own terms.
This also means the quality of your language separation now depends on assets you may not have treated as targeting levers before. Ad copy has always been judged on click through rate and relevance. From late September 2026 it also carries the language routing.
Performance Max is affected, but only on Search inventory
Performance Max gets a partial version of the same change. According to the same 13 August 2026 report, campaign level language will no longer be used for Google Search inventory inside Performance Max campaigns, and language matching on that inventory will work the same way it works in Search campaigns. The setting is not removed from the Performance Max campaign as a whole. It stops applying to one slice of where that campaign serves.
The practical effect is that a single Performance Max campaign will run under two different language rules at once. On Search inventory, the creative and the landing page decide. On the rest of the Performance Max surface area, the campaign setting still holds. Advertisers who treat Performance Max as one undifferentiated bucket will not see this split in the interface, because there is no per-channel language column to inspect.
Which campaign types keep the setting
For all other channels the campaign level language setting still applies. Search Engine Land lists Display, YouTube and Demand Gen among them. If your account leans on those channels for language separation, nothing about your setup breaks in late September 2026.
This is the part most easily lost in a headline. The change is specific to Search and Search style inventory. It is not an account wide removal of language as a concept, and a Display campaign that targets Thai speakers keeps doing what it does today.
This is a confirmed rollout, not a fresh announcement
Google first signalled that language targeting would be removed with a timeframe of "by end of 2025". That earlier signal came and went without the removal happening, and Relevant Audience wrote about it when it was first flagged. What the 13 August 2026 reporting adds is three things that the earlier signal did not contain: a firm date of late September 2026, the explicit inclusion of AI Max for Search campaigns, and the carve-out that applies the Search behaviour to Google Search inventory inside Performance Max.
Treating this as a brand new announcement would misread it. The correct reading is that a long signalled change now has a date attached, and the scope has been drawn wider than the original signal implied, because AI Max for Search did not exist as a named product when the first notice went out.
What changes where
The change does not hit every campaign type the same way. This table sets out what the 13 August 2026 report describes for each one.
| Campaign type | Campaign level language setting after late September 2026 |
|---|---|
| Search campaigns | Removed. Matching uses ad creative language, landing page language, and Google's understanding of the user's languages |
| AI Max for Search campaigns | Removed, on the same basis as Search campaigns |
| Performance Max, Google Search inventory | No longer used. Language matching works the same way as in Search campaigns |
| Performance Max, other inventory | Campaign level language setting still applies |
| Display, YouTube, Demand Gen and other channels | Campaign level language setting still applies |
What to check in your account before late September 2026
The window between 13 August 2026 and the rollout is the time to find the campaigns where the setting was doing real work. A few checks are worth running now.
- List every Search campaign whose language setting is anything other than "All languages", and note what that setting was compensating for. A campaign set to a single language with generic, language neutral ad copy is the one most exposed.
- Open the ad copy in each of those campaigns and ask whether a reader could tell the intended language from the headlines and descriptions alone. If a headline is a brand name and a phone number, it declares nothing.
- Check the landing page for each ad group. A campaign pointing every language variant at one bilingual page loses its clearest signal, because the page cannot declare two languages at once.
- Find the pairs of campaigns that exist only because of the language split. Two campaigns with identical keywords, identical budgets and different language settings were built to separate audiences that Google will now separate for itself.
- Look at Performance Max campaigns with a non-default language setting and accept that their Search inventory will stop honouring it while the rest of the campaign continues to.
None of this needs to be executed today. The value of doing it in August is knowing which campaigns will behave differently in late September, rather than discovering it from a traffic shift afterwards. Accounts that run tightly written copy against language specific pages will barely notice. Accounts leaning on the setting to do work the creative was not doing will notice a lot. If you want that review handled alongside the rest of your account structure, our Google Ads management work covers exactly this kind of settings migration.
What this means for Thai marketers
Thai advertisers are more exposed to this than most, for a structural reason. Running parallel English and Thai campaigns off one keyword set, separated by the language setting, is a normal build in this market. That separation stops working in late September 2026, and the campaigns will start competing for the same auctions on the strength of their creative instead.
Bilingual Bangkok audiences make the effect sharper. A Thai speaker with an English language phone, an English browser and an English Google account is exactly the profile that Google's automated matching now decides for. Under the old setting an advertiser could force that user into the English campaign or the Thai campaign. From late September 2026, Google reads the ad and the page and makes the call.
The practical controls that remain are the ones you write. Ad copy in one language, top to bottom, with no half English headline sitting in a Thai ad group. Landing pages at separate URLs per language rather than one page with a toggle, so the page itself declares which language it serves. Keyword sets that match the language of the copy around them. These are content decisions, not settings decisions, which pushes the work from the campaign panel to the page. Teams already running proper Thai and English page pairs are in good shape. Teams pointing both languages at one URL should fix that first, and our content team handles that kind of split when the pages do not exist yet.
One more Thai specific note. Because the setting disappears rather than being replaced, there is no equivalent lever to rebuild in a different place. Anyone waiting for a migration path to appear in the interface will be waiting for something the report does not describe.
What the source did not say
Three things are genuinely unknown from the Search Engine Land report of 13 August 2026, and it is worth stating them rather than guessing.
The report did not say whether existing campaigns keep their language setting visible in a read only state after the rollout, or whether the field vanishes entirely from the settings panel. It did not say what happens to historical language reporting, so whether past performance data segmented by language remains queryable is unknown. And it did not say whether any opt-out exists for advertisers who want to keep the setting, which on the face of a removal seems unlikely, but the report does not address it either way.
Anyone telling you the answer to those three questions is going beyond what has been published.
Frequently asked questions
When exactly does the campaign level language setting disappear?
Late September 2026, according to the Search Engine Land report published on 13 August 2026. No more precise date has been published, so plan against the end of September rather than a specific day.
Does this affect Performance Max campaigns?
Partly. Campaign level language will no longer be used for Google Search inventory inside Performance Max, and language matching on that inventory will work the same way as in Search campaigns. On all other Performance Max inventory the campaign setting continues to apply.
Do I need to rebuild my English and Thai campaigns before then?
Not rebuild, but check. The campaigns that need attention are the ones where the language setting was separating audiences that the ad copy and landing page do not already separate on their own. If your Thai ads point at Thai pages and your English ads point at English pages, the signals Google will use are already in place.
Will my existing language setting stay visible after the change?
The source did not say. Search Engine Land did not state whether the setting remains visible in a read only form on existing campaigns or is removed from the interface, and Google has not published that detail as of 13 August 2026.
Is there a way to opt out and keep manual language targeting?
The source did not say. No opt-out was mentioned in the 13 August 2026 report, and no alternative control was described as replacing the setting for Search or AI Max for Search campaigns.
Does this change apply to Display and YouTube campaigns?
No. For all other channels, including Display, YouTube and Demand Gen, the campaign level language setting still applies after late September 2026.
If you run Search or Performance Max campaigns in more than one language and you are not sure which of yours were relying on the setting, that audit is a short piece of work now and a messier one in October. Talk to us about a pre-rollout review of your Google Ads account.
