Does your website have significant US traffic, and do you want to monetize your inventory more effectively with Google demand through Google Ad Manager?
Choosing the right monetization setup and the right Google MCM partner can make a significant difference to your fill rate, CPM, RPM, yield, and overall publisher revenue.
In this guide, we'll explain the difference between Google AdSense and Google Ad Manager, how Google AdX fits into the ecosystem, how MCM works, and what publishers should consider when choosing an or MCM partner for US traffic.
Google AdSense Monetization
Google AdSense is one of Google's publisher monetization products. It allows website owners to display eligible Google ads on their websites and earn advertising revenue.
To get started with AdSense, publishers generally need to:
-
Create or use an existing Google AdSense account.
-
Add their website to AdSense.
-
Complete the required site verification process.
-
Ensure that the website complies with Google's publisher policies.
-
Place the required AdSense code or verification method on the website.
-
Submit the website for Google's review and approval.
-
Complete any required account verification, such as identity and payment-address verification.
-
Once approved and fully set up, configure eligible AdSense ad formats, including Auto ads where available.
Publishers should always review the latest Google AdSense eligibility requirements and policies before applying.
AdSense can be a straightforward solution for publishers looking for a simple way to monetize their websites with Google demand.
However, publishers with significant traffic, particularly those with a high percentage of US traffic, may want to explore a more advanced monetization setup.
If you are considering moving beyond basic AdSense monetization, you can also read our guide on how to get a Google AdX account and choose the right AdX partner for publishers.
Google Ad Manager and Google AdX Monetization
It is important to understand that Google Ad Manager (GAM) and Google Ad Exchange are not the same product.
Google Ad Manager is Google's publisher ad-management platform. It provides publishers with tools to manage, serve, and optimize advertising across their digital inventory.
Google AdX, or Google Ad Exchange, is a programmatic marketplace within Google's advertising ecosystem. Ad Exchange features can be available to eligible publishers through Google Ad Manager.
For more information, see Google's official Google Ad Exchange documentation.
With Google Ad Manager, publishers can manage different types of advertising demand and transactions, depending on their account and setup.
These can include:
-
Google AdX demand
-
Google Open Bidding
-
Prebid and header bidding
-
Direct-sold campaigns
-
Private auctions
-
House or backfill campaigns
-
Programmatic Guaranteed campaigns
-
Other eligible third-party demand
This gives publishers greater control over their inventory and monetization strategy than a basic AdSense setup.

How Can a Publisher Access Google AdX?
There are different ways for eligible publishers to access Google Ad Exchange.
One option is working with an eligible Google Certified Publishing Partner (GCPP) through Multiple Customer Management (MCM).
Google provides information about Ad Exchange eligibility and access in its official Ad Exchange documentation.
MCM, or Multiple Customer Management, allows a parent publisher to manage the account or inventory of a child publisher.
Google currently provides two primary MCM delegation types:
-
Manage Account (MA)
-
Manage Inventory (MI)
The exact setup depends on the publisher's account, the partner relationship, and the agreed monetization structure.
Publishers can learn more about Google's MCM framework in the official Google MCM documentation.
For a detailed explanation of MCM and how these delegation models work, see our Google MCM guide for publishers.
What Is MCM Manage Account (MA)?
With Manage Account (MA), the publisher's Google Ad Manager account remains the publisher's account.
The MCM parent receives permission to manage the child publisher's account and inventory.
The inventory remains in the child publisher's Google Ad Manager account, allowing the publisher to continue operating within its existing GAM environment.
According to Google's MCM documentation, the Manage Account model allows the parent publisher to manage the child publisher's account while the child remains the account owner.
This setup can be useful for publishers that already have an established Google Ad Manager account and want professional monetization and yield-management support while maintaining their existing account environment.
What Is MCM Manage Inventory (MI)?
With Manage Inventory (MI), the publisher delegates specific inventory to the MCM parent publisher.
The delegated inventory is managed through the parent publisher's Google Ad Manager account.
The parent can then manage the relevant delegated inventory and its associated monetization setup.
Google provides additional information about the Manage Inventory MCM model.
The exact implementation, responsibilities, payment structure, and commercial terms depend on the MCM relationship.

Why Choosing the Right MCM Partner Matters
Access to Google demand is only one part of successful publisher monetization.
The right MCM partner can help publishers optimize their inventory through:
-
Google AdX demand
-
Google Open Bidding
-
Prebid and header bidding
-
Multiple SSPs and demand partners
-
Floor-price optimization
-
Ad-unit optimization
-
Viewability optimization
-
Yield optimization
-
Traffic-quality monitoring
-
Revenue and performance analysis
For publishers with a high percentage of US traffic, demand quality and competition for each impression can be particularly important.
A strong monetization setup should therefore focus not only on gaining access to Google demand, but also on creating healthy competition between eligible demand sources.
Publishers interested in expanding their demand stack can learn more about Google Open Bidding and Open Auction.
How to Choose the Right AdX / MCM Partner for US Traffic
Choosing an MCM partner should not be based only on whether the partner can provide access to Google demand.
Publishers should evaluate the partner across several areas.
Google Relationship
Before signing with a partner, ask:
-
Is the company an eligible Google MCM partner?
-
What type of MCM relationship will be used?
-
Will I retain control of my existing GAM account?
-
How will the partner manage my inventory?
-
What responsibilities will remain with me as the publisher?
Google provides an official Certified Publishing Partner directory that publishers can use when researching eligible partners.
Demand and Technology
Ask the partner:
-
Does the partner provide Google AdX?
-
Does the partner support Google Open Bidding?
-
Does the partner support Prebid?
-
How many demand partners or SSPs can compete for my inventory?
-
What type of US demand can the partner provide?
-
Can the partner optimize my existing demand stack?
Performance
You should also understand how the partner approaches:
-
Floor-price optimization
-
Fill-rate optimization
-
RPM improvement
-
Viewability
-
Ad-unit optimization
-
Traffic-quality monitoring
-
Invalid-traffic prevention
-
Revenue reporting
Commercial Terms
Before moving your inventory, clarify:
-
What is the revenue share or technology fee?
-
Is the fee calculated on gross or net revenue?
-
What are the payment terms?
-
Is there a minimum traffic requirement?
-
Is there a minimum revenue requirement?
-
Is there a minimum contract period?
-
Are there any setup or integration fees?
Account and Operations
Also ask:
-
Who controls the GAM account?
-
Who receives Google's payment?
-
What reporting will the publisher receive?
-
How frequently is optimization performed?
-
What happens if the publisher decides to change partners?
-
Can existing demand partners continue operating alongside the new setup?
These questions can help publishers compare partners based on net revenue, technology, support, transparency, and long-term account management, rather than simply choosing the partner offering the highest headline revenue share.
Why US Traffic Matters
Not all website traffic has the same monetization value.
A publisher with a significant percentage of US visitors can benefit from strong advertiser demand, but US traffic alone does not guarantee higher CPMs or revenue.
Publisher monetization performance can depend on multiple factors, including:
Traffic quality + geography + device + ad format + viewability + auction competition + seasonality + demand sources + floor strategy
For this reason, publishers should evaluate their complete monetization stack rather than focusing on geography alone.
The objective is to maximize the value of each eligible impression by creating healthy competition between demand sources while maintaining a good user experience.
