Ad Tag Viewer is the proprietary tool developed by Marfeel that allows partners on the One Ad per Page business model to examine their ad configuration for every ad position in their setup. 

Ultimately, Ad Tag Viewer allows Marfeel partners to closely review the ad tags that were implemented for their Marfeel Progressive WebApp (PWA) including the ad's position, the ad server being used, targeting, etc. and ensure they are accurate and correct.

How to use Ad Tag Viewer

  1. Enter the publication's domain with the following query parameter in the address bar:


    For example:

  2. For every ad position in the partner's Marfeel Progressive WebApp (PWA), the publisher's ad tags are displayed with the relevant information including:
    1. size
    2. slotName

    3. targeting ( position, format, ad Slot, platform, section, level)

      The information displayed depends on the type of ad and ad server used for the ad space. The above example is for DFP (DoubleClick for Publishers). The following are some other examples:

      Google AdSense




  3. For Marfeel's ad positions (the second position for One Ad per Page partners), only Marfeel is displayed.
