The Previous Page extension is used to persist the name of the previous page for use on the subsequent page.
How it works
The Previous Page extension adds a variable to the data layer named
previous_page_name. The value of this variable is set to the value of a data layer variable from the previous page. You specify which data layer variable to use as the page name and the extension will save this value in a cookie so that it can be used on subsequent pages.
Here is a simple example where
page_name is used. It shows what value to expect in
previous_page_name as a visitor navigates through a series of pages. Notice that
previous_page_name is not set on the first page in the session.
Using the extension
Once the extension is added, the following configuration option is available:
- Page Value: Select the data layer variable that contains the page’s name.
The extension automatically saves the value of this variable and sets it to
previous_page_name on the next page view.
