Reach rate
The share of a creator’s followers a post actually reaches — increasingly low on algorithmic feeds, which is why follower counts overstate distribution.
How INFLU measures it
Estimated from observed reach patterns across the tracked index; a high reach rate signals content the algorithm actively distributes.
