How are line items set up in Google Ad Manager (GAM)?

How do I get started with UAM?

  1. Create an account using the invitation code and the approved site in the invitation email. If you haven’t received an invitation email, see if you qualify here.
  2. Set up your GAM account with a UAM order and line items so GAM can receive UAM bids. We have automated this step with a one-click push.
  3. Integrate the JavaScript on your website’s page header so ads on your page can request bids from UAM.
  4. Set up your payment information so you can start receiving payments.

Reporting includes bid requests, impressions and earnings with filters for sites, ad slots, sizes, price points, and devices.

What are the fees for using UAM?

UAM charges a 10% transaction fee from SSP and Amazon bid prices prior to conducting a first price auction.

I received an invitation which mentions one approved site but I own more sites. Can I use UAM on all my sites?
