Somewhere in Munich this week, a person typed "best accounting software for a small consultancy" into ChatGPT — and next to the answer, for the first time, sat a paid ad. In the week of August 18, OpenAI expanded ChatGPT Ads to 31 European markets, including Germany, France, Spain, Italy, the Netherlands, Belgium, Austria, Poland and the Nordics. For European small businesses, a genuinely new advertising channel just opened, and it sits at an unusual spot: the exact moment a customer is asking who to buy from.
What OpenAI actually launched
The mechanics, from OpenAI's own announcement: ads appear only for users on ChatGPT's Free and Go plans — Plus, Pro and Enterprise stay ad-free — and they are, in OpenAI's words, clearly labeled and separate from ChatGPT's answers, not woven into them. Advertisers get CPM and CPC bidding plus conversion optimization, geo-targeting and custom audiences, and measurement through an OpenAI Pixel, a Conversions API and third-party integrations. Access is initially gated through OpenAI's Ads Solutions team and agency partners, with a self-serve Ads Manager promised later in the summer; businesses can register interest at OpenAI's ads site.
This is not an experiment anymore. OpenAI piloted ads in the US in February 2026, then rolled them out to eight more markets — including the UK, Canada, Japan and Brazil — over six months before touching the EU. According to The Next Web, ChatGPT now counts around one billion weekly active users, roughly 20 percent of whom show commercial intent in their conversations, and OpenAI's enterprise marketing chief Colin Fleming says ad revenue has grown more than 25 percent since the start of August alone.
Why this channel is different from Google or Meta
On Google, you bid on what someone types. On Meta, you interrupt what someone scrolls. In ChatGPT, you appear next to a synthesised recommendation — often at the tail end of a genuine decision process: "compare these two CRMs for a five-person team", "find me a physiotherapist in Lille who takes evening appointments". That 20 percent commercial-intent figure is the whole pitch. These are not impressions; they are moments of asking.
Early data suggests the shelf is also remarkably empty. Analysis by search intelligence firm Adthena of the markets that launched earlier found ads appearing on only about 4.5 percent of eligible queries, with an average of 1.06 ad items per response — against 3.53 on a comparable Google results page. Retail and fashion took an outsized 39 percent of early ad slots, but less obvious categories such as logistics (about 12 percent), home and garden (12 percent) and beauty (10 percent) performed well, which hints that quieter B2B and service niches are still wide open. Thin competition usually means soft prices; Adthena's read is that early CPCs are gentler than in mature channels, though nobody has published reliable European CPM benchmarks yet.
How it fits with your organic AI visibility
If you read our April piece on answer engine optimization — whether your business comes up when customers ask ChatGPT for recommendations — this is the paid counterpart to that organic work, and the two compound. An ad can put you into the consideration moment, but the model's organic answer still frames the conversation around it. A business that is both cited in the answer and present in the ad slot occupies the whole moment; a business that buys the ad while its organic presence says nothing risks paying for a stage it hasn't dressed. Keep doing the unpaid work: accurate structured information on your site, consistent listings, reviews, the pages that answer real questions. Ads rent the moment; organic visibility owns it.
Testing it without betting the budget
A sensible small-business test does not need five figures. Weeks 1–2: baseline. Before spending anything, ask ChatGPT the ten questions your customers would ask — in your language, your city, your category — and record who gets mentioned and whether ads appear. Adthena's advice to baseline competitor activity while the market is thin applies doubly to SMBs. Weeks 3–6: one campaign, one goal. Register via OpenAI's ads site or your agency, and run a single geo-targeted campaign on your highest-intent service with a few hundred euros. Install the OpenAI Pixel or wire up the Conversions API from day one — without it you will only ever see clicks, not customers. Weeks 7–8: judge like an accountant. Compare cost per enquiry against your existing Google and Meta numbers, not against hope. Keep what beats them; kill what doesn't.
The honest caveats
Nobody knows what this costs at scale. Early softness in CPCs is a snapshot of an empty auction. As self-serve Ads Manager opens later this summer, prices will find their level, and it may not be SMB-friendly in every category.
Measurement is young. The Pixel and Conversions API shipped with this expansion; attribution norms, view-through rules and third-party verification are all still settling. Treat early dashboards as directional.
GDPR questions are real. Custom audiences and pixel-based conversion tracking mean personal data processing, which in the EU means a lawful basis, updated privacy notices and consent banners that actually cover it. OpenAI says conversations stay private from advertisers and data is never sold, but the compliance duty for your pixel sits with you, not with OpenAI. The Next Web notes this rollout lands in one of the world's strictest markets for data and advertising — expect regulator attention, and expect the rules to move.
Access is still gated. Until self-serve arrives, small budgets go through agencies or OpenAI's sales team, which favours bigger spenders. There is no shame in preparing now and spending later.
And your customers on paid plans will never see the ads. If your buyers skew professional, a chunk of them sit on ad-free tiers. Factor that into expectations.
A channel worth watching, not worshipping
The pattern from every new ad platform — Google in 2002, Facebook in 2009, TikTok in 2020 — is that early movers in thin auctions got cheap attention, and disciplined testers beat enthusiastic spenders. ChatGPT Ads in Europe looks like the same movie: a real opportunity, a lot of unknowns, and a short window where a modest budget buys disproportionate visibility because your competitors haven't arrived yet.
Whether that budget is better spent here, on your organic AI visibility, or on something else entirely depends on where your customers actually decide — and that is a question about your business, not about OpenAI. Cresly's AI Readiness Scan helps you map exactly that: where AI, paid or organic, genuinely fits your marketing and operations, and what to try first.
