After transforming the way we search for information, ChatGPT is now set to reshape another part of the digital ecosystem: online advertising.
OpenAI is gradually rolling out ChatGPT Ads, a system that allows advertisers to appear within ChatGPT’s conversational environment.
Initial tests began in the United States in February 2026 before expanding to several markets, including the United Kingdom, Mexico, Brazil, Japan and South Korea. France officially joined the rollout on August 24, 2026.
One important clarification: not all ChatGPT users will see advertising.
OpenAI currently limits ads to adult users on the Free and Go plans. ChatGPT Go is its lower-cost subscription plan. Plus, Pro, Business, Enterprise and Edu subscriptions remain ad-free.
The system is still new and its rollout is gradual. But one thing is now clear: ChatGPT is becoming a new advertising environment.
And given the growing role of AI assistants in search behavior, the arrival of ChatGPT Ads deserves close attention.
ChatGPT Ads: What Exactly Are We Talking About?
Ads are clearly identified as sponsored content and are separated from the response generated by ChatGPT.
This distinction is essential: advertisers pay to appear in an advertising space, not to influence the AI’s response.
OpenAI also states that its advertising systems are separate from the conversational model and that advertisers cannot steer, rank or modify ChatGPT’s responses.
On paper, the boundary is therefore clear.
From the user’s perspective, however, it may be much less so.
The Major Difference with Google Ads: Conversation
On Google, user intent is primarily expressed through a search query.
For example:
“Accounting software for SMBs”
The advertiser then tries to determine which keywords match its products or services and position its ads against those searches.
On ChatGPT, the user can go much further:
“I run a 40-person SMB. We currently use several tools to manage our accounting and invoicing, but they don’t communicate well with each other. I’m looking for a simpler solution that can be used by several employees and integrated with our CRM. What would you recommend?”
The difference is considerable.
This conversation potentially contains the user’s needs, company profile, current challenges, constraints and decision-making criteria.
Intent is no longer expressed in just a few words: it develops throughout the conversation.
From Keyword Targeting to Intent Targeting?
For years, Search Marketing has largely been structured around keywords.
What terms are our prospects searching for? What search volume do they represent? How competitive are they? How much are we willing to pay to appear for these queries?
With conversational advertising, this way of thinking could gradually evolve.
The question could become: in which conversations, and in response to which intentions, do we want our brand to appear?
The change may seem subtle. It is not.
Two users using different words can express exactly the same need. Conversely, the same query can hide very different intentions.
Understanding context could therefore become a central factor in advertising performance.
The Real Risk: Can ChatGPT Introduce Advertising Without Losing Its Credibility?
ChatGPT’s value is largely built on a particular relationship with its users: they ask it a question expecting an answer they perceive as independent of commercial interests.
Introducing advertising inevitably disrupts that perception.
Even if OpenAI clearly separates ads from its responses and states that advertisers cannot influence them in any way, one question remains: will users make the same distinction?
Imagine that a user asks:
“What is the best car insurance for me?”
ChatGPT suggests several options and, immediately alongside them, an advertisement appears for one of those companies.
Even if clearly identified as sponsored content, this proximity can create ambiguity: is the brand there because ChatGPT considers it relevant, or because it paid to appear?
Google has faced this issue for years. But the situation is different with a conversational AI.
Google is perceived as a search engine providing results.
ChatGPT acts more like an assistant that analyzes a situation, forms an opinion and can even recommend a solution.
Trust therefore plays a much more central role in the experience.
OpenAI is clearly aware of this. In its communication around ChatGPT Ads, the company strongly emphasizes the independence of its responses, the separation between advertising and generated content, and conversation privacy.
But this technical separation will also need to become a separation that is perfectly clear to users.
If users start wondering whether a recommendation is genuinely the best answer or whether it has been influenced, even indirectly, by an advertiser, OpenAI could undermine one of ChatGPT’s most important assets: its credibility.
The challenge of ChatGPT Ads will therefore not be purely an advertising challenge.
It will also, and perhaps above all, be a challenge of trust.
What About Conversion Measurement?
With Google Ads, we are used to analyzing a relatively straightforward journey :
Query → Ad → Click → Landing Page → Conversion
On ChatGPT, the journey could be much less direct.
A user might discuss a problem with ChatGPT, discover several solutions, see a brand appear, continue the conversation and then return to that company several days later through a Google search or direct visit.
The journey could therefore look more like this:
Conversation → Exposure → Consideration → Branded Search → Visit → Conversion
How much of that conversion should be attributed to ChatGPT Ads?
Clicks and conversions will obviously remain essential metrics, but they may capture only part of the real impact of certain campaigns.
Attribution and incrementality will therefore be particularly important issues to monitor.
Will ChatGPT Ads Compete with Google Ads?
Google retains considerable power over transactional searches and explicit purchase intent.
But ChatGPT is opening up a different territory.
Google excels when users already have a relatively clear idea of what they are looking for.
ChatGPT can intervene earlier, when users are still trying to understand their problem, identify possible solutions or compare their options.
The two environments could therefore become more complementary than competitive.
Acquisition strategies will likely need to learn how to combine traditional SEA with conversational advertising.
From SEO to GEO… and Now to AI Ads
- With SEO, brands work on their organic visibility in Google.
- With SEA, they purchase visibility around specific search intents.
- With GEO (Generative Engine Optimization), they are now seeking to be understood, cited and recommended in answers generated by artificial intelligence.
ChatGPT Ads now adds the paid counterpart to this new form of visibility.
The evolution could be summarized as follows:
SEO → SEA
GEO → AI Ads
At Firstcom, we are already working on SEO and GEO-related challenges. The arrival of advertising on ChatGPT therefore naturally opens up a new area of observation for our acquisition teams.
It is still too early to know what role ChatGPT Ads will play in companies’ advertising strategies.
But two key challenges are already becoming clear.
For advertisers, the challenge will be learning how to capture intent within a conversation.
For OpenAI, the challenge will be considerably more delicate: monetizing that intent without undermining the trust that gives ChatGPT its value.
That may ultimately be where the success of ChatGPT Ads is decided.
Key Takeaways
ChatGPT Ads, OpenAI’s advertising system, has been rolled out in France since August 24, 2026, following tests launched in the United States in February 2026. It displays sponsored ads, clearly separated from generated responses, exclusively to adult users on the free and ChatGPT Go plans. This system breaks with the keyword-based logic of Google Ads: advertisers no longer target a specific query, but rather an intent that develops throughout an entire conversation, along with its context and constraints. For brands, the challenge is therefore no longer simply to determine which keywords to bid on, but which conversations they want to appear in.
Two risks accompany this shift: the potential for confusion between neutral recommendations and paid advertising, and a less linear conversion measurement model than the traditional query-click-purchase journey. Google and ChatGPT are likely to remain complementary rather than direct competitors, with Google capturing explicit purchase intent, while ChatGPT enters the journey earlier, during the consideration phase.
