One of the core Data layer variables required every page is the page_type variable.In order to determine the correct page_type value for a given page please follow the flowchart below to understand the logic on how these are defined.As per the previous step, the development of the Tagging specification (SDR) for your product/journey the Tag management team would have already gone through this with you, and it will help define the values needed within the Tagging specification, so the flowchart below is just for context. However again, when there are additional changes made post the Tagging specification being completed, and if the XFT have resources that have the competency to modify the Tagging specification themselves then this can help them to define the values for any new/modified pages.
