MCC (My Client Center) is the legacy, yet still industry-standard acronym for what is officially known today as a Google Ads Manager Account.
It is a master “umbrella” account that allows marketing agencies, corporations, and large e-commerce businesses to manage multiple individual Google Ads accounts (child accounts) from a single dashboard using a single login.
Why use an MCC account?
For a large organization or an agency, operating without a manager account would be a logistical nightmare (requiring constant logging in and out across dozens of email addresses). An MCC introduces three key operational conveniences:
- Centralized Access: One login allows navigation across dozens of accounts. There is no need to share passwords with individual specialists.
- Consolidated Billing: The ability to pay for multiple accounts from a single collective invoice, which drastically simplifies the work for accounting departments (monthly invoicing with a credit line).
- Resource Sharing: The ability to create remarketing lists and automation scripts that run across all linked accounts simultaneously (e.g., a script that pauses ads for the weekend across 15 different brands in a holding company).
MCC and the Client-Agency Relationship (The Ownership Question)
This is the most critical aspect for a Marketing Manager deciding to partner with an agency (like Delante).
When an agency asks to “link you to their MCC,” it merely means sending a request to connect your account to their master dashboard. It does not mean transferring ownership rights.
- Market best practices dictate that the Client is always the Administrator (Owner) of their individual Google Ads account.
- The agency, via its MCC, only gains access to edit campaigns.
- If the contract is terminated, a single click (removing access) strips the agency of their view of your data, and the entire campaign history remains with you.
🚨 Red Flag: If an agency proposes creating your ad account inside their MCC and refuses to grant you Administrator rights, it is a warning sign. It means that if you end the partnership, you will lose all history and algorithmic optimization data.
The Security Risk (Single Point of Failure)
The MCC account architecture is a double-edged sword. It provides immense convenience but creates a Single Point of Failure. As shown by the rising wave of Infostealer malware attacks, compromising an agency employee who has admin rights to the MCC gives hackers immediate access to all client accounts linked to that structure.
This is why modern organizations use Sub-MCCs (lower-level manager accounts) to segment access (e.g., a separate MCC for B2B, a separate one for B2C) and minimize the blast radius in the event of a cyberattack.
