GEO and AI: Google and ChatGPT Redefine Online Visibility

The Impact of Generative Engines on Online Visibility

The rise of generative engines, such as ChatGPT and Perplexity AI, along with the increasing integration of artificial intelligence into Google's search engine, is disrupting the established rules of online visibility. In this context, Generative Engine Optimization (GEO) emerges as a new analytical framework for marketing professionals. This evolution raises crucial questions: should we fundamentally revise visibility strategies, rethink content, reallocate budgets, or simply rename transformations already underway? To provide clarity, we spoke with Alban Renard, an expert in SEO and GEO, and head of expertise and innovation at CyberCité.

From Page to Chunk: A New Unit of Visibility

The current transformation is not limited to interfaces; it touches the very unit of online visibility. Traditionally, SEO revolved around the web page: content creation, optimization, and positioning. In a generative environment, this logic remains relevant but becomes insufficient. Now, the importance lies in "chunks," those fragments of information that can be extracted, recomposed, and cited in a response. A well-structured paragraph, a comparative table, or a clear definition can exist independently of their original page. Thus, performance no longer relies solely on the ability to generate clicks but on the capacity to provide actionable information for large language models (LLMs).

GEO: An Extension of SEO, Not a Replacement

In this context, a common mistake is to view GEO as an independent lever. Ranking in generative engines does not operate in isolation. Without crawlability, reliable indexing, a solid content architecture, and authority built over time, there is no sustainable visibility. Therefore, GEO does not replace SEO but extends its requirements in a more complex environment, where visibility depends on a set of converging signals: content, brand, dissemination, and proof. The real change is not so much technical as it is organizational, where SEO ceases to be a silo and becomes a component of a larger system.

From Keyword to Intent: A Strategic Evolution

Historically, SEO was guided by keywords, with volumes, clusters, and semantic arbitrations structuring content strategies. However, in a conversational environment, this approach reaches its limits. The user no longer simply formulates a query but expresses a need, which they specify and contextualize. This change in usage necessitates rethinking the strategy upstream. The question is no longer just "which keywords to rank for," but "which decision scenarios to respond to." Understanding intentions, objections, and moments of friction becomes essential, as GEO values not the most optimized content but that which precisely addresses a real situation.

The Brand as a Signal of Credibility

In this new environment, the brand regains a structuring role. Generative engines do not merely aggregate content; they arbitrate between different levels of credibility and mobilize sources deemed reliable. Thus, a brand strongly associated with a topic is more likely to be cited. Conversely, isolated content, lacking external validation or presence in the ecosystem, will struggle to emerge. Visibility, therefore, relies on a set of signals: expert statements, media mentions, third-party content, customer reviews, and semantic relationships between the brand and its areas of expertise.

Producing Actionable and Citable Content

In this framework, the question is no longer about producing more content but about producing actionable content. Emerging formats, such as FAQs, tables, or structured responses, are not inherently high-performing but become so because they reduce ambiguity and facilitate extraction. Citable content is that which clearly formulates a question, provides a precise answer, and can be isolated without losing its meaning. The difference lies in the clarity, density, and uniqueness of the information. In a context of massive production of generated content, the level of demand mechanically increases. Average content does not disappear; it becomes invisible.

An Increasingly Indirect Measure of Visibility

GEO does not challenge traffic measurement but reveals its limitations. Traffic has long served as a central KPI, but it is no longer sufficient. A brand can now be visible and recommended without immediately generating clicks. Value shifts towards less directly observable signals: presence in responses, frequency of citation, persistence over time, influence on decision-making. This necessitates rethinking indicators. The question is no longer just "how much traffic," but "on which critical needs is the brand present, and with what business impact."

GEO as a Revealer of Organizational Challenges

Beyond technical issues, GEO highlights a deeper problem: organizational fragmentation. SEO, social media, content, public relations, product, and CRM have often been managed in parallel. In a generated response environment, this logic reaches its limits. Visibility now depends on the overall coherence of the signals emitted by the company. Organizations that adapt are those that align their teams around a shared understanding of priorities and customer needs. Search becomes a coordination topic.

Towards an Economy of Extraction

GEO is part of a broader transformation of the web. Until now, value rested on the ability to attract a user to a site. Now, an increasing portion of that value is consumed outside the site, through generated responses. The web is entering an extraction logic where content is recomposed. For media as well as brands, this raises a structuring question: how to produce value without seeing it entirely captured by intermediaries? The answer will not be solely technical. It will involve editorial, economic, and strategic choices.

GEO: A Reconfiguration of Search

GEO does not constitute a break from search but exposes its internal reconfiguration. The historical model, based on indexing, ranking, and clicks, relied on a relatively stable value chain. The introduction of generative engines disintermediates a critical part: access to the answer. The consequence is not the disappearance of SEO but a mutation of its function. It is no longer just about optimizing a presence in an index but about making units of information mobilizable in probabilistic synthesis processes. This shift requalifies the criteria for visibility: content granularity, semantic coherence, informational density, and distribution of authority signals.

Performance can no longer be understood at the level of a channel. It becomes an emergent property of a system: interactions between proprietary content, third-party mentions, social proof, and structuring of entities. The point of tension lies here: GEO does not destroy the previous model, but it reduces its readability. The correlation between visibility, traffic, and value diminishes, in favor of a more diffuse exposure, less measurable, but more structuring upstream of decision-making.

Thus, it is not so much a change of tool as a change of regime. Search does not disappear. It ceases to be a navigation space to become an arbitration space.
