IF Hit depth is incremented on every during a Visit and Visit depth only incremented for a Page View hit AND Pagename is not the same as previous, shouldn't the Hit Depth always be either equal or greater than Visit Depth ?
Take the following example with Segment applied ..
Surely if Visit depth was 2 it should have taken at least 2 hits to register so why would Hit depth be at 1 for a (large) percentage of Visit depth = 2 ?
Page A > Link 1 > Link 2 > Link 3 > Page B In this case, Hit Depth would be 1,2,3,4,5 respectively. Visit depth would be 2 pages per visit.
Notice: Hit depth calculates the depth of individual step, whereas visit depth shows the aggregate in a particulat visit. Which is why if you'd breakdown MCID by hit depth, you would see: VisitorID >Hit Depth 1 >Hit Depth 2 >Hit Depth 3 >Hit Depth 4 >Hit Depth 5 But if you break MCID by Visit depth, you would see: VisitorID >Pages per visit:2 and NOT something like: VisitorID >Pages per visit:1 >Pages per visit:2
Since Visit Depth show you aggregate of pages visited during a visit, hence if you break any visit with more than 1 page views, no matter if you break hit depth 1, 2, 3...so on, you will always see aggreagated visit depth.
In above example: If you breakdown Hit depth 1 (or any hit depth) by visit depth, you would see 2 pages per visit.
