The quantity of numbers for dynamic call tracking is based on the site traffic per day (maximum number of simultaneous visitors).
Formula: (number of visitors per day) / 100 + 20%
A site with traffic of 1000 visitors/day needs 12 numbers.
1000/100 + 20% = 12 numbers
After launch, the number of numbers is adjusted based on the statistics on the occupancy of the numbers, which is available in the user’s personal account.
