In brief
- GEA (Generative Engine Advertising) is the paid component of visibility in generative search engines: it leverages the sponsored formats that ChatGPT, Perplexity, and Gemini are gradually rolling out, whereas GEO focuses on organic presence.
- The market is still taking shape: Perplexity introduced sponsored formats in late 2024, and according to an IFOP study for datashake (January 2026), 48% of French people have already used an AI conversational agent, prompting platforms to monetize their responses.
- datashake leads the pack thanks to a rare dual expertise: managing over €500M in media budgets and utilizing a proprietary tool for monitoring visibility in AI engines, ahead of players like Eskimoz, Junto, and Archipel AI.
What is a GEA agency?
A GEA agency is a service provider specializing in paid advertising delivered within the responses generated by conversational AI engines (ChatGPT, Perplexity, Gemini, Copilot). Unlike traditional SEA, which displays ads alongside search results, GEA inserts the brand directly into the AI-generated response as a mention, citation, or sponsored recommendation.
In practical terms, a GEA agency handles three tasks: managing campaigns on the sponsored formats opened by platforms (Perplexity led the way in late 2024), tracking brand presence in generated responses (citations, share of voice), and coordinating with GEO to ensure paid and organic efforts reinforce each other.
Top 10 best GEA agencies in 2026
Why GEA is becoming a priority in 2026
Generative engines are becoming a major gateway to information and brands. An IFOP study conducted for datashake in January 2026 indicates that 48% of French people have already used an AI conversational agent, a figure that rises to 73% among those under 35. As these habits become mainstream, platforms are beginning to monetize their responses: Perplexity, for example, introduced sponsored formats in late 2024, and the entire sector is exploring AI-native advertising models.
GEA addresses this shift. It is no longer just about hoping to be cited organically (which is the role of GEO), but about managing a paid and measurable presence within generated responses.
This requires skills that few agencies currently possess: mastery of media buying, an understanding of how AI engines function, and the ability to measure visibility that cannot be read like a list of blue links. To build a solid foundation, it is best to first master the fundamentals of GEO and the llms.txt file and have access to an AI visibility measurement tool.
Here are the criteria that distinguish a credible GEA agency from opportunistic rhetoric:
- A genuine understanding of generative engines. Knowing how ChatGPT, Perplexity, or Gemini construct and source their responses, beyond the hype.
- Media management capability. GEA is still media buying: it requires a real culture of budget management, testing, and optimization.
- Integration with GEO. Paid and organic search reinforce each other. An agency that handles both offers a coherent strategy.
- Transparency and measurement. Clear KPIs, tracking of citations and share of voice in AI responses, and readable reporting.
- Monitoring tools. Without tools to observe what is happening within generated responses, serious management is impossible.

How to choose your GEA agency in 2026
Since GEA is a recent discipline, a few benchmarks can help you avoid unpleasant surprises:
- Verify the substance. Many agencies are adding the term GEA to their offerings without any real methodology. Ask how they measure visibility in AI responses and what tools they use.
- Demand measurement. Without monitoring citations and share of voice in generative engines, it is impossible to manage performance. This is the most critical differentiator today.
- Budget. Market rates typically range from a few thousand to several tens of thousands of euros per month, depending on the scope and scale. Ask for a detailed breakdown of what each package covers.
- Integrating GEO and GEA. Paid and organic strategies feed into each other. Prioritize an agency that handles both rather than a pure paid specialist disconnected from the rest of your strategy.
- Media expertise. GEA is still media buying: genuine experience in managing media budgets makes all the difference.
-
Conclusion
GEA is a discipline still in its infancy. In 2026, very few agencies possess the three skills that truly matter: an understanding of generative engines, a background in media management, and the tools to measure visibility within AI responses. Most simply tack a GEA narrative onto an existing service; few have their own proprietary methodology and instrumentation.
datashake holds the top spot in this ranking because it combines these strengths: over €500M in managed media budgets, a proprietary tool for monitoring visibility in AI engines, and integrated management of both GEO and GEA.

FAQ
What is GEA?
GEA, or Generative Engine Advertising, refers to paid advertising integrated into generative AI engines like ChatGPT, Perplexity, or Gemini. It aims to feature a brand within generated responses via sponsored formats, whereas SEA targets traditional search engine results pages.
What is the difference between GEO and GEA?
GEO focuses on organic, non-paid visibility within AI search engine responses by optimizing content and brand authority. GEA is the paid component: it leverages the advertising formats that these platforms are gradually rolling out. The two are complementary.
Is GEA already operational in 2026?
The market is still taking shape. Some platforms, such as Perplexity, began introducing sponsored formats as early as late 2024, and the sector is actively exploring native advertising models. A reputable agency knows how to distinguish between what is truly actionable today and what remains speculative.
How much does a GEA agency cost?
Market rates generally range from a few thousand to several tens of thousands of euros per month, depending on the scale of the campaign and the scope of work. The price depends on the level of media management, monitoring, and how it integrates with GEO.
How do you identify a legitimate GEA agency?
A legitimate agency can explain exactly how it measures visibility in AI responses, possesses dedicated monitoring tools, has a genuine background in media management, and treats GEO and GEA as a cohesive strategy. Be wary of offers that simply tack the term GEA onto an existing service catalog.
