How this was measured

We sent two shopping-intent prompts (“what are the best brands for plant-based protein” and “I’m shopping for plant-based protein — which brands should I consider”) to Perplexity, OpenAI GPT-4o mini and Anthropic Claude. Each answer was parsed for the brands it recommended. A brand’s count is the number of the 6 answers in which it appeared. Answers vary by model, prompt and week; treat this as a snapshot, not a quality ranking.
