Invite a child publisher

Publishers can request access to another publisher's inventory. The publisher requesting access is known as a "parent publisher." The publisher who shares their inventory is a "child publisher."

Parent publishers can send invites to one or more child publishers. 

Note that the MCM child network approval process usually takes a few days, but in some cases it can take 2-4 weeks.

Invite one child publisher

1. Sign in to Google Ad Manager.

Add the remaining details:

   This company name must be unique, and not shared by other child publishers.
7. Enter the email address of the child publisher to whom the invitation will be sent.
   This email address must be unique among active child publishers.

      The box is checked by default.

Ad Manager provides a preview of the email invitation that will be sent to the other network to request access to the network's inventory. Your network name and ID are included.

9. Click Send invitation.

Invite multiple child publishers

You can invite up to 1000 child publishers at once. To get started, we suggest inviting a smaller number and gradually increasing it until you’re familiar with the process. 

To invite multiple child publishers, you use a CSV file. You can upload a single file for Manage Inventory and Manage Account children. For Manage Inventory entries, don’t include revenue share data or you’ll get an upload error.

1. Click Admin  MCM Child publishers.
2. (Optional) To review the required format, click Download sample CSV file.
3. Choose an upload option:
   • Click Browse and select your CSV file.
   • Drop your CSV file into the box.
4. After your file uploads, click Confirm.

If any error messages appear after your upload, correct the file and upload it again.   

Follow up on an invitation

A child publisher’s status affects how parents can follow up on an invitation.

• If the child’s status is “Inactive,” the parent can send a new invitation.
• If the child’s status is “Expired,” the parent can resend an invitation.

Send a new invitation

If a child publisher’s status is “Inactive,” you can send a new invitation to resume an MCM relationship. You can update the invitation with a new proposal. 

Sending a new invitation applies when a parent publisher has withdrawn from a child publisher, or a child publisher has rejected a parent publisher.

1. Sign in to Google Ad Manager.
2. Click Admin  Multiple Customer Management  the Child publishers tab.
3. Next to the child publisher’s name, check that the “Status” column shows “Inactive.”
   Note: If their status is “Invited,” an invitation is pending.
4. Click the child publisher’s name  Send new invitation.
5. In the new invitation, make any changes  click Send new invitation.

Resend an invitation

If the child publisher’s status is “Expired,” you can resend an invitation. The invitation is valid for 90 days. If the child doesn’t accept the invitation within 90 days, you can resend the invitation again. 

If you need to change the proposal, withdraw the invitation so the child’s status becomes inactive, and send a new invitation instead.

Resending an invitation applies when the child publisher does not have an associated network.

1. Click Admin  Multiple Customer Management  the Child publishers tab.
2. Next to the child publisher’s name, check that the “Status” column shows “Expired.”
   Note: If their status is “Invited,” an invitation is pending.
3. Click the child publisher’s name.
4. Make any changes  click Resend invitation.

See how your child publisher is performing

After the other network approves your request, you can view performance and revenue information for your new child publisher under "Payments."

1. Sign in to Google Ad Manager.
2. Click Admin Multiple Customer Management. 
   The "Payments" tab is selected by default.

End the agreement

After an agreement is accepted, the parent or child publisher can end the agreement at any time. This helps publishers ensure their users’ data is processed securely by trusted partners.
