In addition to what everyone else has answered, it is very important for
you to remember that Marketing Channels per hit. NOT per visit. That is
a very common misunderstanding about Marketing Channels.Also, remember
that AA's definition of visit is primarily time-based, i.e. where there
are continuous hits without a break of more than 30 minutes.So the
following is an entirely valid visit in AA, yet notice that the
Marketing Channels will change mid-visit:12:00pm: Arrive at website from
campaign...
