Because a number is worth a thousand words, here is where ChatGPT Ads stands as you read this page. Figures are dated, sources from OpenAI.
This is the annualized revenue level reached by ChatGPT Ads in less than 200 days, as announced by OpenAI on August 31, 2026. This channel is no longer an experiment.
This is the number of European markets opened on August 24, 2026, including France. The self-service Ads Manager followed on August 31.
That is the satisfaction score out of 10 that our clients give us after 3 months.
We promise, we aim for 10/10
ChatGPT Ads is OpenAI's advertising platform, integrated directly into ChatGPT. In practical terms, it works like this:

The ad takes the form of a sponsored card displayed below the ChatGPT response when a product or service is relevant to the ongoing conversation. It contains your name, your favicon, a headline of about 16 characters, a description of about 32 characters, an image, and a link. It is visually separated from the response and labeled "Sponsored." Only users of the Free and Go plans see it.

No keywords, no behavioral profiles. You describe to OpenAI Ads Manager the types of conversations where your offer fits in (the "context hints"), and the system decides on delivery itself. Since July 2026, you can also import your customer lists to include or exclude audiences. This is exactly the work we already do in GEO: identifying the prompts where your prospects make their decisions.

Purchased via CPM or CPC in Ads Manager, available in self-service in Europe since August 31, 2026, with a minimum daily budget of €25 imposed by OpenAI, or approximately €750 per month. Costs per click remain low as long as competition is weak, but that won't last. To effectively cover the conversations to test and obtain enough data to make decisions, we recommend a media budget of at least €2,500 per month, in line with our Google Ads and LinkedIn Ads recommendations.

ChatGPT's responses remain independent of advertisers: this is OpenAI's principle of "Answer Independence." An ad will never make ChatGPT say that you are the best. For that, there is GEO (Generative Engine Optimization), and as it happens: that is also our specialty.

Through countless tests, successes, failures, and adjustments on Google, Meta, and LinkedIn, our Growth Ads team knows exactly how to approach a new platform without burning through your budget. We apply that same discipline to ChatGPT Ads from the very first week.
We are experts in ChatGPT Ads, but also in tracking. We install the OpenAI pixel and Conversions API from day one, and we link conversions to your HubSpot CRM and dashboards. We care about the cost per qualified lead and the revenue generated, not the number of impressions under a response.

We build your context hints just like we build your target prompts in SEO: by mapping the questions your prospects ask ChatGPT at each stage of their decision-making process, then testing multiple targeting hypotheses in parallel. The right context accounts for 80% of performance on this platform.

E-commerce, B2B SaaS, healthcare, services: the right mix of context, landing page, and campaign objective (traffic or conversions) varies. We work with you to determine the role of ChatGPT Ads in your funnel before you spend a single euro.

The goal: quickly determine if ChatGPT Ads is a profitable channel for you. Based on numbers, not gut feelings.
We aren't magicians. We simply use the power of data multiplied by our expertise in Growth Marketing. Here is what sets us apart:
For every campaign, it is essential to measure and analyze everything we do. Our COO & Partner was a team leader at Fifty Five. We therefore train every consultant in tracking and data processing so they are autonomous in setting up your Ads tracking and highly effective at analyzing your data. On a platform that has only been active in France for a few weeks, that is exactly where the difference is made.
The essence of an Ads strategy agency is, of course, expertise. Our team was built with the best senior profiles on the market for intent-based platforms, and we have trained them in the best advertising techniques and tools. Our consultants are trained in OpenAI Ads Manager and conversational targeting, and we test the channel on our own campaigns before offering it to you.
"It’s better to be a big fish in a small pond than a small fish in a big one." Growth Room is currently in the sweet spot: experienced enough to have the expertise and deliver excellent service (communication, processes, project management, meeting deadlines), yet still small enough to be agile. Every company we work with is treated as the lifeblood of our agency. You’ll see—the team’s responsiveness and flexibility in managing advertising campaigns are second to none.

While we wait for the first ChatGPT Ads case studies (initial campaigns are currently underway), here is what our Ads methodology produces on other platforms.
No fake testimonials, nothing more authentic than a view in our inbox to know what our companies think of the Growth Room team.

Advertising on ChatGPT is managed through OpenAI Ads Manager (ads.openai.com), which has been available for self-service in Europe since August 31, 2026, or through an agency that manages the account for you. Growth Room sets up the account, installs the pixel and Conversions API, builds context hints, produces creative assets, and manages CPC or CPM bids. You retain ownership of the account and full visibility into your spending.
Yes. OpenAI launched ChatGPT Ads in France and 31 other European markets on August 24, 2026, followed by self-service access to Ads Manager on August 31, 2026. Growth Room has been supporting companies with ChatGPT Ads since its launch in France.
OpenAI requires a minimum daily budget of €25 in Ads Manager, which comes to about €750 per month. This is the technical floor, not a testing budget. Just like with Google Ads or LinkedIn Ads, a budget that is too low won't generate enough data to make informed decisions. Growth Room recommends a monthly media budget of at least €2,500 to properly cover the conversations you want to test and obtain a significant sample size, to be adjusted based on your industry and average order value.
Cost-per-click varies significantly depending on the targeted context and competition, which is still low as of September 2026. We prefer not to publish a range until we have enough consolidated campaigns: Growth Room will share observed figures as soon as our first campaigns allow. One thing is certain: advertisers who position themselves early benefit from low bids that will not last.
Only users of the Free and Go plans. Plus, Pro, and Enterprise subscribers do not see any ads. This is a point that Growth Room integrates into the audience estimation for every campaign, especially in B2B where a portion of decision-makers uses a paid version.
No. OpenAI applies a principle of response independence: the ad is separate from the response and does not alter its content. To be cited within the response itself, you need GEO (Generative Engine Optimization), which Growth Room offers as a complement on our dedicated page.
Yes. OpenAI has offered a conversion pixel and a Conversions API since May-June 2026, as well as a "Conversions" campaign objective. Growth Room installs them from the start and links conversions to HubSpot and GA4 to manage campaigns based on cost per qualified lead rather than impressions.
Both respond to intent, but one to the typed keyword, the other to the context of a conversation. Google Ads remains the most mature and measurable intent channel; ChatGPT Ads reaches your prospects earlier, while they are comparing and reflecting. Growth Room manages both together and allocates budget based on a single criterion: cost per conversion. You can learn more on our Google Ads agency page.
Yes, if your buyers use ChatGPT to compare providers, tools, or approaches. This is the case in SaaS, services, and consulting. With one caveat: only free users see the ads. To reach decision-makers on a paid version, GEO and LinkedIn Ads take over.
Four criteria matter for such a new channel: genuine tracking expertise (pixel, Conversions API, CRM), solid experience with intent-based platforms like Google Ads, a practice of GEO to understand how AIs interpret a conversation, and transparency about what is known and what is still being learned. Growth Room, a Growth Marketing agency in Paris, combines Google Ads, Meta Ads, LinkedIn Ads, and GEO, and has been supporting companies with ChatGPT Ads since its launch in France in August 2026.
