The score accumulated in the Lead score of the visitor will recalculate based on the interval to reduce the lead score upon the period of inactivity.
You can set the recalculating period of the lead score in the Advanced Configuration section of the “Lead Scoring”. In the “When would you like to recalculate the Lead Score?” choose an option from the drop down. By default, it is set to Weekly.
The score will be reduced by 25% from the current value for the interval specified.
For example:
The set condition is Add 25 points to the visitor, if the number of visit is more than 10, and also weekly option is chosen in the “When would you like to recalculate the Lead Score?” Assume that the visitor has a Lead score of 100, and he didn’t turn-up for a week, then the score of 100 will reduce by 25% from the current value. So, now the Lead score will become 75.
