How are occurrences calculated in the navigation module?

In the Navigation Explorer tool, when you select "All pages", the navigation analyses will show you all the pages that follow the chosen page, regardless of where it occurred within the visits.

As there may be more than one occurrence of a page in a given visit, the metric displayed is "occurrences" and not "visits".

A page occurrence corresponds to the number of sequences that may have occurred after this page.

How are occurrences calculated?

In order to understand the counting method, we use the following visit as an example:

The visitor entered the site at page "A" and navigated between pages A, B and C before leaving the site at page B:

In the "All pages" analysis of page A, the above visit will be separated into 3 sequences. Each sequence corresponds to a possible path after page A:

Sequence 1 : A -> B -> C  -> B -> C -> A -> C -> A -> B

Sequence 2 : A -> C  -> A -> B

Sequence 3 : A -> B

It will be displayed as follows in the navigation tool:

There are 3 occurrences of Page A for a single visit.

The method of calculating occurrences look similar to the page views metric, but ignores duplicate page views. If a visit loads a page twice in a row, there will be 2 page views, whereas we will only count one occurrence.

Let's take the example of this visit: Page A > Page B > Page B > Page C > Page C:

The value per page is therefore not exactly the same.
