Each cell is the brand’s average position in that AI model’s answers across the month's capture; indigo marks each AI model’s top answer among the brands shown. A dash means that AI model never named the brand. A model’s own list can be longer than this board, so a position can exceed the number of brands ranked here.
How this ranking is built

“What are the best email marketing software? Recommend the top brands or products that people actually use.”
Brands are then ranked by their AI Recommendation Score: how many AI models recommend them and how often they come up. Presence in real answers is the only input. Read the full methodology →
