A second-level MCC account is a type of advertising account used in Google Ads to link multiple client accounts to a single manager account. The acronym MCC stands for My Client Center, the historical name of the interface Google provides for centralized management of multiple advertising accounts. In English, the term is often referred to as “client center,” but in professional jargon the English acronym remains the most common form.
In Google Ads’ hierarchical model, the second-level account occupies an intermediate position: it sits below a first-level manager account and above individual client accounts. This structure allows agencies, consultants, and large advertisers to manage many accounts in an orderly way, keeping each client’s billing data, access permissions, and operational settings separate.
A container that organizes multiple accounts without serving ads
A second-level MCC account is a manager account that does not serve ads directly but acts as an organizational container for other accounts. It can be linked to a higher-level manager account or operate as an intermediate node in a more complex hierarchy. In practice, it allows you to group multiple client accounts under a single management entity, simplifying repetitive operations and overall monitoring.
The distinction between first and second level mainly concerns the position in the access chain and the ability to delegate permissions. A second-level account can receive access from a first-level account and, in turn, grant access to end clients or other collaborators without those parties seeing the entire structure above.
The levels of the structure and how they connect
The Google Ads hierarchy typically includes at least three levels: the main manager account, any second-level accounts, and individual client accounts. Each level can contain other manager accounts, creating branched structures useful for corporate groups, agency networks, or international projects.
First-level manager account
This is the highest node in the structure. It manages general permissions, can link second-level accounts and client accounts, and usually corresponds to the agency’s or central marketing department’s account.
Second-level account
It functions as a sub-manager. It can be linked to a first-level account, contain client accounts and, in some cases, other manager accounts. It serves to separate business units, geographic areas, or different client portfolios.
Client account
This is the operational account where campaigns are created, budgets managed, and performance data collected. It cannot contain other accounts but can be linked to multiple manager accounts simultaneously.
Why separating accounts pays off
Adopting a second-level MCC account offers several organizational benefits. Among the most relevant are the separation of contexts, the ability to apply granular permissions, and the simplification of operations at scale.
Multi-client and multi-brand management
Agencies that handle many clients can create a second-level account for each business area, avoiding mixing data and settings. The same applies to companies with multiple brands or branches, which thus maintain a distinct view for each entity.
Access control
Permissions can be assigned at the manager account level, reducing the risk of unwanted access to client accounts. A collaborator can receive access only to the relevant second-level account without seeing the rest of the structure.
First and second level: what changes in operations
The following table summarizes the main operational differences between a first-level manager account and a second-level MCC account.
| Feature | First-level account | Second-level MCC account |
|---|---|---|
| Position in hierarchy | Highest node | Intermediate node |
| Link to other managers | Not required | Possible upward |
| Contains client accounts | Yes | Yes |
| Contains other managers | Yes | Yes, in some cases |
| Direct ad serving | No | No |
| Billing management | Centralized or delegated | Generally delegated |
The creation and linking sequence
Creating and linking a second-level account requires a sequence of operations that depend on the Google Ads interface and available permissions. The typical steps are listed below.
- Access the first-level manager account with a profile that has administrator permissions.
- Create a new manager account or use an existing one to designate as the second level.
- Link the new manager account to the first-level account via the manager-to-manager linking function.
- Verify that the link is active and permissions are correct.
- Link existing client accounts to the second level or create new ones.
- Assign permissions to users, distinguishing between read-only and full access.
- Configure billing and currency settings for each client account, if necessary.
- Check the overall hierarchy and document the structure for future reference.
Frequently asked questions
What is the difference between MCC and second-level account?
MCC is the historical name for the manager account in Google Ads. A second-level account is an MCC that sits under another manager account, so it represents a particular case within the same category.
Can a second-level account serve ads?
No. Manager accounts, regardless of level, do not serve ads. Campaigns are created and managed exclusively in linked client accounts.
How many client accounts can be linked to a second-level account?
Google Ads does not publish a fixed limit that applies universally to all cases. The actual number depends on current policies and account characteristics, so it is advisable to check the updated conditions in the official documentation.
Who can see the data of linked accounts?
Only users who have been assigned specific permissions. Permissions can be limited to a single account or extended to the entire structure, based on the administrator’s choices.
Can a second-level account be linked to multiple first-level accounts?
Generally, a manager account can be linked to multiple manager accounts, but operational rules may vary. It is advisable to consult the available settings in the interface at the time of configuration.
Is billing managed at the second level?
Not necessarily. Billing can be centralized at a higher level or delegated to individual client accounts, depending on the contract and chosen settings.
