In Google Analytics benchmarking, percentiles (median, 25th, and 75th) represent the distribution of performance metrics within your peer group.
The median is the middle value, while the 25th percentile and 75th percentile represent the lower and upper bounds of the benchmark range.
This range helps you understand where your business stands compared to others, with the goal of identifying areas for improvement. The benchmark range is between the 25th and 75th percentile, giving a clear picture of typical performance within your industry.
