# Prompt style changes how many brands AI answers show

> Peec's 37,804-response study (2026) — ranking/list prompts surface ~20% more brands and keyword-style prompts up to 25% more than open-ended questions; filler length has zero effect.

How a prompt is styled — not just what it means — changes which brands AI engines surface. From Peec's study of 1,754 prompts and 37,804 AI responses across ChatGPT, Gemini, Perplexity, Google AI Mode, and AI Overviews ([published study](https://www.searchenginejournal.com/ai-prompt-intent-keywords-peec-spa/576201/), 2026):

* **Format matters:** asking for a comparison, table, list, or ranking consistently surfaces more brands; a ranking prompt adds about **+20% average visibility** over open-ended questions.
* **Keywords beat conversation:** concise keyword-style prompts ("best CRM small business 2026") yield up to **+25% more brand mentions** than persona-engineered prompts ("You are an IT consultant…"), which broaden into less brand-dense educational paths.
* **Constraints split by engine:** adding budget or feature constraints reduces the brands shown in ChatGPT and Perplexity but *increases* them in Gemini and Google AI Overviews — potentially by triggering extra fan-out queries.
* **Length is irrelevant:** filler and conversational words have effectively zero impact on which brands appear.

For tracking, tag prompts by format — a list prompt and an open-ended prompt do not share a baseline, so mixing styles muddies trends. The wording-similarity thresholds behind the same study: [Prompt wording and AI visibility](/research/prompt-wording-and-ai-visibility).
