Visibility can include a linked citation, an unlinked mention, a recommendation, or another identifiable appearance. These events are not equivalent and should not be blended without showing their weights.
A useful measurement frame
Start with a documented query set, named platforms, a sampling schedule, and clear status definitions. Report presence and absence together so the denominator remains visible.
Why scores differ
Scores vary because providers use different prompts, engines, locations, weights, and sampling windows. A score is most useful when its inputs and changes can be inspected, not when it is presented as a universal truth.
