Google Ads has expanded the regions where advertisers must disclose whether AI was used in their ads, adding California, South Korea, and Vietnam to a list that already included the European Union, India, and New York. The expansion was reported by Search Engine Roundtable on November 5, 2026. The change is small on paper, just three more names on a list, but it points to a bigger shift, as disclosure of AI use in advertising spreads from place to place.
The new additions cover a wide range of markets. California is the largest state economy in the United States and a bellwether for regulation, so its inclusion matters far beyond its own borders, since rules adopted in California often spread to other states. South Korea and Vietnam are significant advertising markets in Asia with their own regulatory traditions, and their addition shows that Google is not treating AI disclosure as a purely Western concern. Together, the three new regions turn a list that was already international into something much closer to a global requirement.
The existing list already included the European Union, India, and New York, which means the disclosure rule was already operating across three continents before this expansion. The European Union has been the most active regulator of AI, India is one of the largest advertising markets in the world, and New York is a major commercial centre whose rules carry weight beyond the state. Adding California, South Korea, and Vietnam to that group fills in important gaps, and it suggests that Google is responding to regulatory pressure region by region rather than waiting for a single global standard to emerge.
The reason disclosure rules spread is that the underlying concern is the same everywhere. When an advertiser uses AI to create an ad, the audience may not realise that what they are seeing was generated rather than photographed, filmed, or written by a person. Regulators worry that this gap in understanding can mislead people, especially when an ad shows a product, a place, or a person that does not quite exist in the form presented. Disclosure is meant to close that gap by telling the audience that AI was involved, so they can judge the ad with full information.
Google's approach of expanding region by region reflects how regulation actually works. There is no single global AI law, so companies face a patchwork of rules that arrive at different times in different places. A platform the size of Google Ads has to comply with each jurisdiction as its rules come into force, which is why the list grows in steps rather than all at once. For advertisers, the practical effect is that a campaign that is compliant in one market may not be compliant in another, and the list of markets requiring disclosure will probably keep growing. The direction is clear even if the destination is not yet fixed.
The first step for advertisers is to know where disclosure is required and to build it into the campaign process rather than treating it as an afterthought. With California, South Korea, and Vietnam now on the list alongside the European Union, India, and New York, a large share of the world's advertising markets is covered, and any campaign with international reach is likely to touch at least one of them. Creative teams should know before they start work whether AI will be used in an ad, because that decision now has a compliance consequence that follows the ad wherever it runs.
The second step is to think about disclosure as a trust issue, not just a legal one. Audiences are becoming more aware of AI-generated content, and an advertiser that is open about its use of AI is likely to be trusted more than one that hides it. For marketers and SEOs, the lesson is that transparency about AI is becoming part of the craft, whether the rules require it or not. The advertisers who adapt early, building disclosure into their workflow and being straightforward with their audiences, will be better placed as the list of regions keeps growing and the expectation of honesty becomes the norm everywhere.
