ChatGPT ads are open in the UK and Europe. Should you buy them, and how do you get found for free?

  • By Dr Josh
  • September 23, 2026

The read. ChatGPT Ads launched in the UK on 11 August 2026 and across 31 European markets from 18 August, with self-serve buying through OpenAI's Ads Manager by the end of the month. Ads show only to Free and Go users, sit apart from the answer, and can be measured with a pixel and a Conversions API. Our view: open the account, run a small test if your customers ask ChatGPT intent questions before they buy, and put the bigger effort into being the source the answer cites, which costs nothing but discipline.

What is actually available

OpenAI started testing ads in the US on 9 February 2026 and expanded through the year: Canada, Australia and New Zealand from March; the UK, Mexico, Brazil, Japan and South Korea from 11 August; 31 European markets including Spain, Germany, France and Italy from 18 August, with self-service through Ads Manager following by 31 August.

The rules are worth reading before the pricing. Ads appear only for logged-in adult users on the Free and Go tiers; Plus, Pro, Business, Enterprise and Education stay ad-free. OpenAI's stated principles include answer independence (ads do not shape the answer) and conversation privacy (advertisers never see the chat). Campaigns support conversion optimisation, geo-targeting and custom audiences, and measurement runs through the OpenAI Pixel, a Conversions API and third-party integrations. OpenAI is also testing placements that show several relevant advertisers together, priced by second-price auction.

The audience is not small. ChatGPT reported 900 million weekly users in February 2026, up from 400 million a year earlier, and passed a billion monthly users in June.

Google is doing the same thing, faster

Ads inside Google's AI Overviews have been live for UK English queries since late 2025, and Performance Max, broad-match Search and Shopping campaigns are eligible without opting in. At Google Marketing Live in May, Google added conversational discovery ads and highlighted answers inside AI Mode, Direct Offers with native checkout, and an Ask Advisor assistant across Ads, Analytics and Merchant Center. Add the AI Max upgrade to Search campaigns through September and the direction is clear: the answer is the new results page, and the ad sits inside it.

Should you buy ChatGPT ads?

Yes, a small test, if two things are true. Your customers ask questions before they buy ("best contrast therapy studio in Canary Wharf", "which builder gel lasts longest", "private dining for 20 in Soho"), and you can measure the result with the pixel and a holdout rather than trusting a platform report. Budget it from the test line, not the Meta line, and give it four weeks.

Not yet, if you sell impulse or purely visual products. ChatGPT is where people go to decide, not to browse. A £12 lip oil does not need an answer; a £1,200 treatment course does.

Never on the strength of the platform's own attribution. This is a new auction with thin reporting. Treat the first quarter as a measurement exercise, and compare it with what the same money buys on Meta and Search.

The bigger prize: being the answer

Most of the value of AI search is free. When someone asks ChatGPT or Google's AI Mode for a restaurant, a studio or a product, the answer cites a handful of sources, and those sources were chosen for reasons you can influence.

  1. Answer first. Every page opens with the answer in two or three sentences that stand alone when quoted. Then the evidence.
  2. Make the entity unmistakable. One name, one address, one phone number everywhere: website, Google Business Profile, Instagram, booking platform. Organisation and LocalBusiness schema on the site. For venues, the menu as text, not a PDF or an image.
  3. Give evidence with dates. AI answers favour claims that carry a number, a period and a source. So do careful customers.
  4. Answer the questions people ask. A three-question FAQ on every service page, written in the customer's words, marked up as FAQ schema.
  5. Earn third-party corroboration. Reviews, press, listings and creators saying the same thing you say. An answer engine trusts agreement.
  6. Stay fresh and fast. A visible updated date, pages that load quickly on a phone, and no content hidden behind scripts.

This is why the Insights section you are reading is built the way it is: an answer at the top, figures with periods and sources, a FAQ at the bottom, and a date on every piece. It is written for a person in a hurry and for the model that will summarise it.

What we would do this quarter

  1. Create the ChatGPT Ads Manager account in the business's own name and invite the agency; install the pixel.
  2. Rewrite the five most-visited pages answer-first, with FAQ schema.
  3. Fix the entity: consistent name, address and phone number across every listing; complete the Google Business Profile.
  4. Run one four-week ChatGPT ads test with a holdout, only if the two conditions above hold.
  5. Track citations: once a month, ask ChatGPT and AI Mode the ten questions your customers ask, and record who gets cited.

Frequently asked questions

Can UK businesses buy ChatGPT ads now? Yes. ChatGPT Ads launched in the UK on 11 August 2026, and self-serve access through Ads Manager opened across the UK and Europe by the end of August. Ads show to Free and Go users only.

How do I get my business mentioned in ChatGPT answers? Be the clearest, most consistent and best-evidenced source for the questions your customers ask: answer-first pages, one consistent business identity across the web, dated evidence, FAQs in the customer's words and third-party corroboration.

Do ads in ChatGPT change the answer? OpenAI's stated principle is answer independence: ads are labelled, sit apart from the response and do not influence it, and advertisers cannot see the conversation.
