Summary
DescriptionClickpath Analysis.png
English: A visual Clickpath Analysis showing the Referers (pages where the visitors come from) on the left and the evaluated objects as rectangles. A greater width than height means a higher percentage of visitors passing to another page; a greater height means a higher bounce rate (visitors leaving). The expanse of the rectangles as well as the thickness of the arrows symbolize the amount of visitors passing this way. On top additional information about one arrow over a time period is shown.
