|Link multiple Ad Manager accounts||
Multiple Ad Exchange accounts can be linked to one Ad Manager account and vise versa.
When this link takes place and you want to use Ad Manager: Ad units or Ad Manager: Placements for rules targeting, you'll be able to see ALL ad units or placements within those Ad Manager accounts, which may include ad units or placements the child publisher doesn't want Ad Exchange to compete against. Therefore, you can only import all or none of the ad units or placements of all Ad Manager accounts into your Ad Exchange account.
If your client is using the ad unit or placement selector, they may be able to see the names of all your Ad Exchange tags.
|Tags per partner/domain (or app) versus Generic tags||
If you don’t have 100% control over where your child publisher is placing your Ad Exchange tag and you are NOT using Ad Manager ad units or Ad Manager placements, you may want to create a tag per partner or a tag per domain/app.
This proves helpful when you are seeing issues such as “Rejected ad requests”. If you use one single tag for all child publishers/domains (or apps) and you happen to run into an issue with rejected ad requests, you’ll be unable to determine where these requests are happening, unless you are using multiple tags.
|Enter child publisher company name||
When you add a child publisher to your account, before you click to send the invitation, we strongly recommend entering the actual name for the child publisher (the child publisher company name) rather than the domain/app.
|Duplicate child publisher registrations||
A company should only have one child publisher registered under a given channel partner with all domains/apps properly associated in the domain/app classification section of the user interface. Duplicate child publishers will be disapproved.
