AI Visibility Score
A single number summarising how often and how prominently a brand appears across AI answers. Every vendor computes it differently and none publishes the formula, so two tools can report very different scores for the same brand on the same day and both be internally consistent. Treat it as a trend line for your own account rather than a figure to compare across tools or quote externally. The question that decides whether any such score means anything is how many runs sit behind it: at a mention rate near 30%, a hundred runs still gives a confidence interval of 21% to 39%.
