You can build the campaign to receive X visitors each Y time.
For example, you want to have 100 Visits every 24 hours for 7 days,
The formula will be:
Runs ( Total orders to be sent): 7
Interval (Break between each run, In minutes): 1440
As result, an Order of 100 Quantity, will be sent every 1440 minutes (24 hours), 7 times total.
This means You will get a total of 700 Visits in 7 Days. 100 Visits per day.
