We have performed an external campaign which drove traffic to a series of 9 separate pan-European countries ... I am looking to find out how many of those visits during that period of time were new visitors (ie. first time visitors to those pages) ... AND.. I also would like to know how many of those new visitors then went on to repeat visit those pages - again, in the same period.
Sequential segments are to help you. The repeated visitors can be defined as "Visited pages A, B, C and then after a visit visited pages A, B, C". The first time visitors are those who visited pages A, B, C minus repeated visitors.
