Chance score
A composite metric combining keyword volume, competition, and your current rank.
Chance score (also called 'opportunity score' in some tools) is a composite metric that ranks keywords by how much potential install lift you could capture by improving your rank for that keyword. It typically combines search volume, keyword difficulty, your current rank, and your competitor's average rank. Higher chance score = better target. Rank Sonar exposes chance score in the Keyword Optimization view to help prioritize which keywords to target with metadata changes.
