ChatGPT Mentions Start With Better Topic Evidence

Introduction

Across 90 prompts we tested in ChatGPT, commercial prompts triggered web searches 78.3% of the time. Informational prompts did so just 3.1%. That gap changes what you should write if you want to appear in a ChatGPT answer. ChatGPT doesn't pull every response from the same place. Some answers come from training data; others use live web search, a behavior called query fan out. The model expands your prompt into multiple. This connects with structured data when the same signal needs a clearer operating decision.

Why this question matters now and how query fan outs come into play

Query fan outs change the content game because the system isn't limited to the literal prompt. It expands the request into multiple background searches, then retrieves and synthesizes across those subtopics. Fan outs trigger parallel web searches tied to the initial prompt, creating opportunities for retrieval, mention, and link citation. Multi query expansion is a core design pattern in modern generative search systems.

The setup: what we tested

The core sample includes 90 numbered prompts, heavily weighted toward informational intent. The sample skews heavily toward informational prompts, with some commercial ones and minimal branded and transactional queries. We structured the experiment around the sectors in the brief: beauty/personal care, legaltech/regtech, and IT/tech.

The result: commercial prompts triggered almost everything

Out of 90 prompts, 20 triggered fan out. Of those, 18 were commercial and 2 informational. Informational prompts made up about 10% of fan out triggers (2 of 20). When they did trigger expansion, they were rewritten into more evaluative, solution seeking subqueries. In other words, 90% of fan out triggering prompts in the core sample came from commercial intent. The contrast is stronger than the raw totals suggest. Commercial.

Methodology: how we performed the analysis

The experiment used 90 prompts across three industries, mostly informational, with a smaller set of commercial prompts and minimal branded and transactional queries. Selected a representative battery of prompts. Observed distribution by prompt metadata. The analysis then followed three steps: Each prompt was classified according to prompt intent labels. We counted the prompts triggering fan out (at least one). We inspected.

Interpreting the results: fan out tends to move down funnel

The cleanest interpretation is that, in this sample, fan outs behave less like open ended topic expansion and more like assisted decision support. Commercial prompts almost always opened the door. Once they did, fan outs usually stayed commercial. The system expanded into comparisons, feature based filtering, product lists, pricing adjacent queries, and brand specific evaluations.

What this means for content strategy

The takeaway isn't to stop writing informational content. It's this: informational content alone is unlikely to align consistently with fan out expansion, at least in this dataset. If your goal is visibility in AI answers tied to product selection, vendor discovery, or option narrowing, you need stronger coverage of pages and passages that match those downstream commercial branches. " which tool should I choose " pages.

Limitations

This result is directional, not universal. 90 prompts reveal a pattern, but not a stable law of AI retrieval behavior. The prompt mix is uneven. Informational prompts dominate the sample, while branded and transactional prompts are barely represented. That means those findings aren't proof of absence. The dataset spans industries but isn't normalized by brand, wording style, or use case. Some sectors may be easier to express. A useful companion note is Visibility Now Starts Before the Search Result, because it looks at a nearby part of the same system. The same pattern also shows up in search visibility, where the practical question is how the signal becomes visible.

What to test next

The next version of this experiment should isolate the question more aggressively and expand the dataset. A follow up should map triggered fan outs back to specific content formats. The goal isn't just to confirm that commercial intent wins. It's to identify which page templates and passage structures best cover the fan out branches AI systems prefer.
