This document outlines the functionality of the Master JS Tag. If you are a publisher using ZEDO for ad serving, please contact Support for the Publisher Guide to access ZEDO’s Master JS Tag.

How it works

The Master JS Tag allows you to generate and add a single JS Ad Tag to multiple ad calls. You can create up to 20 placements of Channels and Ad Dimensions. The Master JS Tag feature is available under the Ad Tag Generator tab.

Generate Master JS Tag

  1. Go to the Ad Tag Generator tab and click on the Master JS Tag button.
  2. From the Ad Slot drop-down list select the desired Channel and Ad Dimension.
    (Note: You can create up to 20 Channel and Ad Dimension combinations)
  3. The Publisher’s name automatically displays once you furnish details in the Ad Slot.
  4. You can click on the More Options button for
    • Research Vendor Tag
    • Demographic Targeting
    • Enable Keyword Targeting
  5. The Master JS Tag gets generated in the box.
  6. Now, simply click on the Email Tags button to send the tags to your publishers.
    Note: While implementing Master tag on your pages ensure you implement the same number of tags in the head and body section.
    Example:
    If you have generated Master Tag for 5 slots then you need to place 5 Ad Tags in the head and body section.
    If you generate Master Tag for 5 slots and place only 1 or 2 corresponding tags in the body section, then you might face discrepancy in the numbers between two Ad Servers, if the ads are created ads using 3rd Party ad code.

Sending Tags

  • Always send tags through the ZEDO interface, or as a .txt file attachment in an email.
  • It is not a good practice to copy tags from the body of an email.

Note

  • Two or more sets of Master JS Tags are not supported on the same webpage.
