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.
What does the data show?

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.
- Each engine answered 72 prompts covering 24 questions, which gives 12 answers per question across the four engines. Intervals are wide at this sample size.
- 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.
- Name extraction also picked up phrases that are not brands, such as 'Short answer' (19) and 'Bottom line' (15).
- Google AI Overviews are scored only on the 60 lookups where an overview appeared, not on all 72.
- One question, "ServiceTitan vs Housecall Pro: which is better for a small plumbing business?", names two software brands, so their counts include up to 12 answers to it. The equipment-maker results are the same without it.
- Intervals treat each answer as independent, so they understate uncertainty for the 24 repeated questions.
