Path is a set of your landing pages, offers and redirect rules which traffic has to meet in order to be redirected to these offers and landing pages. You can add several redirect rules for each path, but pay attention: to be redirected to a certain path traffic must fit all the redirect rules you have specified for this path. Therefore for each set of redirect rules you have to create a new path. If the traffic fits the redirect rules of a few paths simultaneously, it will be redirected to the path with a higher priority(higher in the list).
