Visibility Rate is intensity: citations divided by checks. Ten prompts across five assistants makes 50 checks. If you're cited in 12 of them, that's 24%.
Keyword Coverage is breadth: the share of your prompts where at least one assistant cited you. Those same 12 citations can come from 3 prompts or from 9. Coverage is 30% in the first case and 90% in the second.
We put the same questions about Dubai developers and hotels to six AI systems. Emaar came up in 79% of relevant answers, Aldar in 13%. Meraas showed up in 70% of Grok's answers and 5% of Gemini's. Being a big brand predicted none of it.
