Waarom krijg ik zoveel bezoeken van 0 seconden? Hoe kan iemand mijn site bezoeken gedurende 0 seconden?
Visit length is determined by the movement of visitor from one page to another so if visitor visits just single page then visit length displayed is 0 seconds. Also if visitor visit couples of webpages and moves to a different site then we cannot record how much time he spent on last page and hence time displayed is in several hours.
