Hi,
PageView : A page view is counted each time a browser requests a page.
Visits : A visit is one or more page views belong to one or more categories over time by a uniquely identified client (visitor) in a session over the specified time interval.
Unique Visitors: The number of unique visitors over the specified time interval. A unique visit may contain multiple visits by a user.
A pageview is a discrete event, but Visits and Unique visits are not discrete. A visit may contain multiple pageviews, these pages may belong to different categories/boards. When you aggregated visits on category/board belongs to a visit, it is counted across multiple categories/boards. The same logic applies to Unique visitors. Adding up Visits and Unique visitors after category/board level aggregation like below is not a right metric. There is an overlap of a visit on different boards.
Let's take an example, a user with user-id:1234 visits (visit-id:visit111) to the community and activities are as follows.
User Landed/login into community Home (Home does not belong any category) - 1st pageview - 1 visit - 1 Unique Visitor
viewed a page let's call it page111 in category Category-1/Boards-1 Community. - 2nd pageview - 1 visit - 1 Unique Visitor
viewed another page let's call it page222 in category Category-2/Boards-2 Community - 3rd pageview - 1 visit - 1 Unique Visitor
For this user activity in a visit here is the metrics
_______________________________________________________________________________
In summary, metric counted a - 3 pageview - 1 visit - 1 Unique Visitor. ( 1 pageview attributed to community Home Page that may not belong to any category)
_______________________________________________________________________________
When aggregated on category/board level
Category-1/Board-1 Community. - 1 pageview - 1 visit - 1 Unique Visitor
Category-2/Board-2 Community - 1 pageview - 1 visit - 1 Unique Visitor
________________________________________________________________________________
If you do add up(like you did in CSV). 2 pageview - 2 visits - 2 Unique Visitor .
Adding up Visits and Unique visitors after category/board level aggregation is not the right metric.
