Why is "All" not the average of the list of AI Search Visibility Topics?

Why is "All" not the average of the list of AI Search Visibility Topics?

The AI Search Visibility "All" percent located in the Topics box is a metric that aggregates all the questions linked to those Topics and shows how often your brand appears, compared to the total number of questions. The All percent in the Topics box is not the average of the search visibility for each individual topic.

For example, if Topic A has high visibility with many questions, and Topic B has fewer questions but lower visibility, the AI Search Visibility "All" percent in the Topics box will consider the total questions, not just the average visibility of A and B.
  1. The "All" metric located in the AI Search Visibility Topics box is a comprehensive view that reflects visibility across every question related to all Topics, not just an average of individual topic visibilities.
  2. If some Topics don't have questions, the "All" percent still reflects brand appearances across the entire set of questions.
