How we measure
- These three questions are fixed and asked every day:
- “What are the best SEO tools for a small business? Name specific products.”
- “Which SEO tool would you recommend for a content marketing team in 2026, and why?”
- “Compare the leading SEO platforms. Which would you pick?”
- ChatGPT through Cloro's monitoring API, with web search off, so it answers from model knowledge.
- Claude (claude-haiku-4-5) through Anthropic's API, answering from model knowledge without web search.
- Gemini through Cloro's monitoring API, which returns the consumer Gemini answer.
- Claude answers all three questions daily. ChatGPT and Gemini answer the first question for as many categories as their rate limit allows each day.
- A language model lists the brands named in each answer, and only names that literally appear in the answer are kept.
- These are our own fixed questions. No customer data is used on this page.
