Experience Analytics Entry/Exit pages display [unknown page]

Question

Can anyone shed some light on why I am seeing numerous entries for [unknown page] in the Experience Analytics -> Behavior -> Pages -> Entry pages/Exit Pages reports?

I need to track down what is causing so many [unknown page] entries in the reports and I'm not sure where to start.

Answer 1

The [Unknown page] entries may appear due to following reasons:

1. Items may have been deleted which were already tracked.
2. Pages are opened and tracked which are not Sitecore items e.g. You created a test.aspx page in root folder and open it, This page does not have a corresponding item in Sitecore and will show as Unknown.

You can check URLs and Names of these pages in "Page URLs" section in Behavior tab.

Answer 2

Tracked pages have an ItemId field that is saved to the Collection database. During the generation of reports, all information about the page will be fetched from the corresponding Sitecore item. In case there is no associated item in the content tree, [unknown page] will be shown.

This will become a problem when you are tracking page hits that don't have a Sitecore item associated with them. If you have such a page tracked, there are two options for improving the reports:

Don't track the page

I've described the various ways to prevent a page from being tracked. See this post:

Override item information

You can track custom pages and override the item and URL information for the page hit. You can do that by including the following in the code of your page:

Tracker.Current.CurrentPage.SetItemProperties(itemId, "en", itemVersion);
Tracker.Current.CurrentPage.SetUrl("/some/url");
