A lot depends on the number of prepaid visits and on the area in which the KeyPosition Visits service is active: websites which deal with eroticism, tourism and travelling, telephony and other popular areas will surely reach the number of purchased visits in shorter lengths of time compared to niche areas or to sites clearly b2b.
In the form to be filled in for the purchase of the service there is however section where you can state if the activity must reach the number of purchased visits within a certain date (e.g. in case of promotion of events or initiatives which have a precise date of beginning and end). If you wish to promote an event, you need to activate the keyposition at least 60 days before the beginning, in order to structure the advertising activity in the best possible way and to cover in an effective way the period previous to the event.
