ChatGPT Ads Goes Self-Serve in Europe and the Middle East: What to Test First

If you plan media for clients in Cyprus, the UK or the Gulf, ChatGPT has so far been a visibility question: how to get a brand cited in the answer. Since August 31 it is also a buying decision. OpenAI has started opening self-serve Ads Manager, in beta, to advertisers outside the US, so an agency in a covered market can open an account and bid on clicks without going through OpenAI's sales team or a partner.

What happened between August 31 and September 10

On August 31 OpenAI said advertisers could buy ChatGPT ads directly through Ads Manager "across India, Europe, the Middle East, and North Africa", according to PYMNTS. Digiday reports that ads launched in 31 European markets earlier in August through select agency partners, with beta self-serve access there from August 31. PYMNTS adds that OpenAI put the ads business at a $1 billion annualized run rate after about 200 days, with tens of thousands of advertisers.

A run rate describes pace, not a total. Digiday puts it at roughly $83 million a month and estimates that OpenAI booked around $330 million in ad revenue over the first eight months of 2026.

On September 4, Search Engine Roundtable listed a batch of ChatGPT Ads changes:

• Shopping results in ChatGPT now come only from brands that send product feeds, according to analyst Juozas Kaziukėnas.
• An Ads Manager plugin to create, manage and analyze campaigns from inside ChatGPT or Codex.
• Custom audiences that can be edited without rebuilding, used for exclusions below 25,000 matched users and grown beyond 5 million.
• New conversion-matching fields: hashed phone, first name, last name, region and postal code for the Pixel, and Android GAID for the Conversions API.

On September 10, Search Engine Land reported, citing The Information via Investing.com, that OpenAI will no longer approve ads for standalone image- and audio-generation products, while video-generation tools can still advertise. Adobe, which promoted Acrobat Studio and Firefly during the pilot, is among those affected. The change was reportedly communicated to partners rather than announced publicly.

What changes mechanically

Self-serve changes who can run a test. For an agency, a ChatGPT test no longer starts with a sales conversation. It needs a budget, a landing page and conversion tracking that works.

It also separates two jobs that were easy to blur. OpenAI says ads are clearly labeled, sit apart from ChatGPT's responses and do not influence the answers, according to PYMNTS. If that holds, buying ads does not buy citations. Your generative engine optimization work still decides whether the brand appears in the answer; the ad buys a labeled slot beside it. Plan and measure the two separately.

Bidding sets the measurement requirement. According to AI News, CPC and outcome-optimized bidding account for the majority of campaigns, and Pixel and Conversions API integrations are the main way advertisers pass conversion events back. An outcome-optimized campaign learns only from the events you send it, which is why the new matching fields matter: each extra identifier is another way to connect a click to a sale.

What to test first

Start narrow. Before promising a client a launch date, confirm that their country is live in Ads Manager. Search Engine Roundtable quotes OpenAI describing the rollout as select countries, and WinBuzzer notes that user availability in India and MENA remained unknown. Then test in this order.

In the EU and the UK, treat the Pixel like any other advertising tag, behind the consent banner, and give hashed identifiers the same privacy review as customer matching elsewhere; the client's privacy counsel decides.

The DSA ad repository: write every ad as if it were public

On August 31 the European Commission designated ChatGPT a Very Large Online Search Engine under the Digital Services Act, which Euronews calls a first for an AI chatbot. Search Engine Journal reports OpenAI's figure of approximately 159.1 million average monthly active recipients of ChatGPT search in the EU over the six months ending March 31, 2026. The Commission says the obligations apply by January 2027; Euronews reported the end of November.

Search Engine Journal lists the duties: an annual independent audit, data access for vetted researchers and, where applicable, a public ad repository. Fines can reach 6% of global annual turnover. Article 39 of the DSA, which covers very large search engines that show ads, requires the repository to show each ad's content and brand, who it ran for and who paid, when it ran, whether it targeted particular groups and the main parameters used, including exclusions, and its reach, by member state where applicable. Each ad stays searchable until a year after it last runs.

One caveat: ChatGPT was designated because it can search the web, and no report we have seen explains how the repository will treat ads shown in ChatGPT. Plan as if every ChatGPT ad served in the EU will be in the repository:

• Every claim needs a substantiation file you would show a regulator a year after the flight ends.
• The main targeting and exclusion parameters become public, so use only parameters you would defend on the record.
• In regulated categories such as forex, gaming or real estate, today's risk warnings become searchable evidence of what you said and when.

What the category block says about the platform

The reported block is narrow, but it shows how eligibility works here. Search Engine Land notes that the restriction reportedly comes as OpenAI expands its own competing image and voice capabilities in ChatGPT. The platform owner competes in some categories and, if the report holds, can close one to advertisers without a public announcement.

Three things follow. If a client sells something ChatGPT already does natively, treat its eligibility as revocable and keep ChatGPT a test line in the paid media plan, not a core channel. Keep creative, audiences and tracking portable so budget can move quickly. And reread the advertising policies at every launch, not once at account setup.
