- Each question went to Claude (Sonnet) as a fresh chat, with web search on, the way a homeowner would ask it.
- A company counts when an answer recommends it. Mentions as a company to avoid are not counted and not shown.
- We ran all 40 questions twice. The top 10 was the same both times, and shares moved 3 points on average.
- This is one AI on one night. ChatGPT, Gemini and Google's AI Overviews can answer differently. It is not an endorsement, and nobody paid to be listed.
