Unique Visitors Vs Visits
I've created a free form table, my dimension is marketing channel and my metric is visits the number comes up as 111,567 . However, if I were to add in unique visitors to the same table with the same date range, my visits changes to 156,283. Is there a reasoning for this change?
I saw that @jennifer_dungan had answered a question similar to this but, I'm not sure if there was any reference to the date range.
From answered the post, it says that visit number is based on All time data, but I'm confused if that would supercede the date range I have selected. Does adding unique visitors add more users to the data pool for visits to pull from?
Thanks in advance!
