Advertising in ChatGPT.
Your customers ask ChatGPT their buying questions. We place your ads below its answers, right when intent is highest, and run your campaigns for performance.
Be there when they decide, not just in the results
High purchase intent
Someone asking ChatGPT describes their need in detail. Conversational advertising captures that intent at the moment the decision is made, not three clicks later.
Conversational format
Your ads appear below ChatGPT's answer, clearly labeled as sponsored. Users can ask about them or message you directly. We craft the message so it genuinely answers the question asked.
A channel with little competition
Advertising in ChatGPT has been open in France since August 2026. Brands that position now capture attention before auctions get crowded.
Measured results
Impressions, clicks, cost per acquisition, conversions: we tie every euro invested to a concrete result, with clear, actionable reporting.
A setup that adapts to your market
From eligibility audit to daily management, we build your ChatGPT Ads campaigns as a full acquisition channel.
We analyse your market, your personas and the buying questions your customers ask AI assistants. We define goals, budget and the messages that convert.

A call with one of our experts to see whether advertising in ChatGPT can become a profitable acquisition channel for your business.
Contact usThe questions we get asked most.
ChatGPT Ads refers to advertising served in ChatGPT: ads displayed below the assistant's answer, labeled as sponsored and selected from the context of the conversation. They do not influence the answer itself. It's a conversational acquisition channel, open in France since August 2026, that complements your organic search and your other campaigns.
SEO and GEO work on your organic visibility: being found and cited for free by Google and AI engines, right inside their answers. ChatGPT Ads is a paid lever: you buy a placement below the answer, with no influence on what ChatGPT writes. The two reinforce each other: a brand already cited organically gains credibility on its ads.
OpenAI publishes no rate card: you pay per thousand impressions or per click, through auctions, with a minimum budget of €15 per day. Actual cost depends on your industry and competition. We work on a media budget you set, plus management fees, framed from the strategic audit to aim for profitability. See also our pricing.
We start with an audit of your market and the buying questions your customers ask AI assistants, then define targeting, messages and budget. The simplest step is to contact us for a first conversation: we'll quickly tell you whether the channel fits your business.
Not all of them. In France, OpenAI mainly opens consumer goods, local services, travel and entertainment, digital products and education. Legal, health and financial services, alcohol, gambling and politics are prohibited, and business services are reviewed case by case. The eligibility audit settles the question before any investment.
A test runs on a controlled media budget, at least the €15 per day OpenAI requires, enough to gather usable data without committing large sums. We set a starting amount together, then scale only what proves profitable.
We connect click and conversion tracking before launch, with the OpenAI pixel or its Conversions API, and check that a real request comes through. You get reporting that ties impressions, clicks, cost per acquisition and conversions to your goals, not just volume metrics.
No, ChatGPT Ads works on its own. But the two complement each other: a brand that's visible organically converts its ads better. The ideal is to combine SEO and GEO with advertising to cover the whole buying conversation.
