I am comparing visits referred from Page A to total visits of target Page B. There is no other way to reach Page B except via one link on Page A. I am counting the referrals from Page A by a specific link instance occurring in the visit.
Currently the number of visits with the link instance are half that of the total visits to Page B. Direct visits to Page B is not the issue. I don't expect them to match, but I also don't expect them to be so different.
I'm not looking for solutions, just possible causes. Thank you!
