MA vs MI: Which Google MCM Access Model Is Right for You?
Google's Multiple Customer Management (MCM) program is designed to give publishers a structured path to access Google Ad Exchange (AdX) through certified partners. However, one of the most common questions publishers ask is this:
What is the difference between MA (Managed Account) and MI (Managed Inventory), and which one is right for me?
At PubShine, we've helped hundreds of publishers across different regions get approved under both models. This blog will explain how they differ, what each offers, and how to choose the model that fits your goals and current stage.
Understanding Google's MCM Models
Before diving into the comparison, let's define both models:
Managed Account (MA)
In this model, the MCM partner creates a new Ad Manager account for the publisher under their network and maintains full administrative access. The publisher is linked to the MCM partner for all monetization activities.
Managed Inventory (MI)
In this setup, the publisher uses their own Ad Manager account but gives the MCM partner access to specific inventory (ad units or mapped sections). The publisher retains ownership of the GAM account while the partner helps manage monetization.
Key Differences: MA vs MI
| Feature | Managed Account (MA) | Managed Inventory (MI) |
|---|---|---|
| GAM Account Ownership | Partner owns the account | Publisher owns the account |
| Setup Process | New account created and fully managed by partner | Existing GAM account connected via mapping |
| Control Level | Limited publisher control | Full publisher control over account |
| Ease of Approval | Easier for new publishers | Requires a policy-compliant GAM account |
| Transparency | Partner handles reports and performance | Full transparency in your GAM interface |
| Ideal For | Beginners or non-technical publishers | Experienced publishers with GAM setup |
| Flexibility to Switch Partner | Limited (new GAM needed) | High (just unmap inventory) |
Which One Should You Choose?
Let's help you make the decision based on your current situation.
Choose MA If:
- You do not yet have a Google Ad Manager account
- You are new to programmatic advertising or Google AdX
- You want hands-on assistance and a quick start
- You are looking for a low-barrier entry into premium demand
Perfect for: Publishers who want to test monetization performance first before investing time into managing a GAM account.
Choose MI If:
- You already have a Google Ad Manager account
- You have experience managing ad units, reports, and policies
- You want to retain full ownership of your GAM
- You may work with multiple MCM partners over time
Perfect for: MI offers greater independence, transparency, and long-term flexibility. However, your account must be policy-compliant and meet eligibility criteria.
