Manage Inventory

Update your tags to MCM

The instructions are only applicable if you are presently using Google Publisher Tag on the inventory you are representing. This tag change won't affect your current ad serving.

Once Multiple Customer Management is enabled, the existing Google Publisher Tag should be updated to add the child network code to the ad unit definition on the page in order to use inventory management. The ad unit remains configured in the parent's Ad Manager network. Use the tag generator or manually update the JavaScript.

As part of the MCM migration, child sites with Ad Exchange tags will have to be re-tagged with GPT tags that include a child publisher number. 

GPT code sample

<head>
  <script async src="https://securepubads.g.doubleclick.net/tag/js/gpt.js"></script>
  <script>
    window.googletag = window.googletag || {cmd: []};
    googletag.cmd.push(function() {
      googletag
         .defineSlot('/1234567,1234/Travel', [300, 250], 'div-gpt-ad-1568729559138-0');
         [...]
    }
  </script> 
 </head>

The highlighted parameter, 1234, represents the network code for the child publisher. 1234567 represents the parent network code.

In the code on the page, you must add the highlighted parameter to the .defineSlot() function. This will allow the child publisher network to be recognized and help creatives serve correctly when “Manage Inventory” is enabled. No changes to the line items or targeting are necessary.

Child publishers can remain on SPM until you invite them to use MCM. After you invite a child publisher to use MCM, make sure your child site is approved and marked "Ready." You should update the GPT tag at least 2 hours after your child publisher's site is approved.

App tag sample

For MCM Manage Inventory, the app ad unit code needs to be updated with the parent and child network similar to display GPT tag. The following segment must be placed within the code block; '/1234567,1234/parent_ad_unit'.

1234567 represents the parent network code, while 'parent_ad_unit' represents the name of the ad unit in the MCM MI parent network.

Refer to the corresponding SDK documentation (Android, iOS) for specific methods to set the ad unit ID within your app.
