Previous Page Extension

The Previous Page extension is used to persist the name of the previous page for use on the subsequent page.

Prerequisites

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.

Page page_name previous_page_name
Home Page Home - Welcome (not set)
Search Page Search for iPhone Home - Welcome
Product Page iPhone 10 Product Details Search for iPhone

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.
