Why is ChatGPT Ads becoming a topic for brands?

ChatGPT Ads is arriving as generative AI becomes a staple in the search and purchasing habits of French consumers.

In May 2026, 66% of French people reported using generative AI tools, compared to 59% in 2025 according to The Media Leader – Havas Market study.

This shift is also impacting the customer journey. 55% of users reported making a purchase after consulting an AI, compared to 47% in 2025.

Among 18-34 year olds, 52.5% reported using a conversational AI first to search for information, recommendations, or advice.

The search journey is evolving. Users no longer just browse a list of results; they can now directly request an answer, a comparison, or a recommendation.

It is against this backdrop that OpenAI is rolling out ChatGPT Ads in France and 31 other European markets in August 2026.

ChatGPT Ads: what is it and how does it work?

ChatGPT Ads is an advertising solution that allows companies to display **ads within the ChatGPT conversational environment.

In practical terms, ads can appear below ChatGPT responses, featuring the advertiser's name, logo or favicon, a headline, body text, an image, and a landing page. They are clearly identified as advertisements and remain separate from the response generated by ChatGPT.

For the advertiser, the goal is to be present at the moment a conversation aligns with a need that their offer can address.

How does ChatGPT Ads target users?

ChatGPT Ads takes into account the context and intent of the conversation.

The system also analyzes the landing page, the ad copy, and the contextual cues provided by the advertiser.

These cues are not exact-match keywords. Instead, they describe the needs, situations, or use cases that an offer addresses.

Example: a footwear brand can target the need for "cushioned running shoes to start a 5K."

This logic distinguishes ChatGPT Ads from traditional search engine advertising (SEA).

How much does ChatGPT Ads cost and how do you launch it?

ChatGPT Ads currently offers three objectives : views, clicks, and conversions. The minimum daily budget is €15 for accounts billed in euros.

How do you create a ChatGPT Ads campaign?

A campaign is built in several steps:

2. Set the budget : daily or total.
3. Choose the target countries and platforms .
4. Create ad groups around specific needs.
5. Write several ad variations.
6. Add UTM parameters to track traffic.

ChatGPT Ads marks the beginning of the GEA

The GEA, or Generative Engine Advertising, refers to advertising within generative search environments. ChatGPT Ads is a concrete application of this today.

Academic research also uses the broader term Generative Engine Marketing (GEM) to describe the marketing ecosystem of generative engines. It notably encompasses advertisements and sponsored responses.

The difference from SEA lies primarily in the environment (Google vs. LLMs) and the user journey:

SEA: query → results → click → website

GEA: question → conversational answer → advertisement → click

GEA, GEO, and SEA: what are the differences?

These three approaches follow different logics, but are becoming complementary.

The GEO therefore becomes complementary to ChatGPT Ads. A strategy can work on both organic and paid visibility within generative environments simultaneously.

To learn more about this difference, check out our article GEO vs. SEO: what is it and why should you integrate it into your strategy?.

GEO prepares the ground, while GEA buys visibility.

The GEO (Generative Engine Optimization) seeks to improve a brand's ability to be naturally understood, cited, or recommended by generative engines.

GEA follows a different logic: buying visibility within those same environments.

The two can therefore work together.

A GEO strategy can build a brand's organic presence in AI responses, while a GEA campaign allows for the rapid testing of specific messages, offers, or segments with users showing relevant intent.

And SEA retains its role on traditional search engines.

The challenge is not to replace Google Ads with ChatGPT Ads, but to gradually build an acquisition mix adapted to the fragmentation of search journeys.

What are the limitations of ChatGPT Ads?

ChatGPT Ads is still a new channel. Advertisers therefore have less historical data to rely on compared to established advertising platforms.

Several limitations must be taken into account:

• historical performance remains limited;
• conversational targeting does not guarantee placement on a specific query;
• results are not directly comparable to those of Google Ads;
• availability and features are still evolving;
• the acceptability of advertising within AI responses remains an open question.

According to a study by The Trade Desk, 87% of consumers do not fully trust AI tools.

The Havas Market study also shows that 26% of users state that ads within responses would reduce their trust in the neutrality of AI. Only 24% would accept relevant sponsored content without issue.

Ad relevance and transparency will therefore be decisive for this new format.
