What happened
Extensive research conducted by Kevin Indig, analyzing 1,094 product and service categories, has revealed a startling reality: only 15.2% of these categories have a clear "owner" within ChatGPT-generated responses. This implies that for approximately 89% of AI search demand, no single brand has yet established itself as the undisputed authority. Furthermore, the study indicates that being featured in the sources cited by the AI does not accurately predict whether a brand will be explicitly named in the output text, challenging traditional SEO assumptions.
Technology context
AI-based search, represented by tools like OpenAI's ChatGPT, Perplexity, or Google Gemini, operates fundamentally differently from traditional search engines. While Google displays a list of links based on ranking algorithms, Large Language Models (LLMs) synthesize information to provide a narrative answer. The process by which an AI chooses which brands to mention is known as "Generative Engine Optimization" (GEO). This relies not just on domain authority, but on how an entity is represented within training datasets and real-time browsing data.
Why it matters
For digital marketers and business owners, this window of opportunity is narrow. Currently, the "market share" of AI mentions is fragmented and not yet dominated by rigid advertising algorithms. If a brand manages to become the default answer for a specific category (e.g., "best project management tool"), it stands to gain massive market share without traditional PPC costs. However, the fact that citations do not guarantee mentions means that digital PR and backlinking strategies must shift focus toward semantic association and contextual relevance rather than just volume.
Key terms explained
- LLM (Large Language Model): An AI trained on massive text datasets to understand and generate human-like contextual language.
- GEO (Generative Engine Optimization): The practice of optimizing web content to increase the likelihood of being used and cited by generative search engines.
- Share of Model (SoM): A metric emerging to measure how often a brand is mentioned by AI models compared to its competitors.
- Zero-Click Search: A search result where the user's query is answered directly on the results page (or chat interface), requiring no further clicks to a website.
Impact
In the short term, we will see an intense race among brands to "educate" AI models through high-authority content and niche publication mentions. In the medium term, it is highly likely that OpenAI and Google will introduce clearer advertising formats within these chat responses, effectively closing the current window of "free organic visibility." Companies that fail to adjust their SEO strategies now risk becoming invisible to a generation of users who exclusively use AI assistants for purchasing decisions.
What's next
We expect SEO monitoring tools to launch dedicated features for tracking "AI Visibility." The battleground is shifting from "Page 1 of Google" to "First Mention in ChatGPT." Brands will likely invest heavily in structured knowledge bases and data partnerships to ensure that AI models recognize them as thought leaders in their respective fields.
