I had actually had what sounds like the exact same question and submitted a case to understand further. Here is the explanation Khoros provided: " The data for the number of visits is the same data. However, the three areas you highlighted in your screenshots that are labelled "Visits" are actually all measuring slightly different scenarios using the same master dataset. The discrepancy between the Content total Visits at the top vs. the sum of the individual content categories is due to those numbers actually measuring different things. One of my colleagues had a great analogy to help explain this: If you think of the community as a mall, then each visit to the mall would count as a visit in the Visits listed at the top of the page. Once you are in the mall, you may go to different stores. Each visit to a store (category) is marked in the visits column under the categories. You may go to multiple stores, but it would only count as one visit to the mall. The best option for the total number of visits to your community will be the Visits number listed on the traffic overview page. This number will include visits to the community including the community landing page (extending the analogy, this could be seen as the sidewalk or front doors of the mall)."
