Version 2. This version replaces the first version of this study, first published August 11, 2026. It uses measured counts, so the two versions are not comparable. Version 2 asks 24 questions three times each on ChatGPT, Claude, Gemini and Perplexity (288 answers) and adds Google AI Overviews. Every rate comes with its count and a 95% interval.

How this study was measured
24 questions × 3 runs each × 4 AI engines = 288 answers + 72 Google searches · 72 AI Overviews
24 questions, each asked 3 times on each engine, measured October 26, 2026. Market: United States, English. The destination site was not mentioned to any engine. Entities count as named when they appear in the answer text or the extracted entity list; products, imprints and research arms roll up to their parent.
| Engine | Model IDs called | Asked | Returned | Grounded |
|---|---|---|---|---|
| ChatGPT | gpt-5-mini | 72 | 72 | 72 |
| Claude | claude-sonnet-5-5 | 72 | 72 | 69 |
| Gemini | gemini-3.7-flash | 72 | 72 | 72 |
| Perplexity | sonar-pro | 72 | 72 | 72 |
| Google AI Overviews | DataForSEO Google SERP (live, advanced) | 72 | 72 shown | 72 |
Own-domain citations count a domain plus all its subdomains, with the same rule in every table.
Definitions
- Appearance rate: answers naming the entity ÷ answers returned, with Wilson 95% intervals.
- First mention: average order in which the entity first appears (1 = first).
- Own-domain citation: grounded answers citing the entity's domains ÷ grounded answers.
- Citation share: citations to the entity's domains ÷ all citations.
Limits
- Measured on one day, October 26, 2026. Answers came from each engine's API (model IDs above); the consumer apps can answer differently.
- The question set has 24 questions with 12 four-engine answers each. Questions 1–12 came from the original card and questions 13–24 were added. A different question mix would produce different rates.
- Claude returned 72 answers, but only 69 were grounded in sources. Rates based on its own-domain citations use 69 as the denominator.
- Mention rate measures whether a company is named, not whether the description is accurate or favourable.
- Names are counted when they appear in an answer's text, so longer forms such as legal company names (for example "Meta Platforms, Inc." or "Ralph Lauren Corporation") count toward the brand.
- One question, "OpenAI vs Anthropic vs Google for enterprise AI?", names three companies, so those counts include up to 12 answers to it. Without it, OpenAI and Google are still the top two.
- Intervals treat each answer as independent, so they understate uncertainty for the 24 repeated questions.
