In short: an MCC (manager account) is a level above the accounts, for managing several without sharing passwords. The rule that avoids heartbreak: account ownership is never handed over. The client owns the account and grants access; the agency works from its MCC. An MCC does not merge data or share budget: it only manages access and billing.
So far we have talked about one account. But as soon as you manage more than one — several companies, several countries with separate billing, or you are an agency — you need a level above: the manager account, which everybody still calls by its old initials, MCC (My Client Center). And with the MCC comes the subject that causes the most grief in this industry: who has access to what.
What is a Google Ads MCC (manager account)?
A manager account is a Google Ads account with no campaigns: its only job is to group other accounts and let you get into them without switching user. From the MCC you see a dashboard with every linked account, its spend and its results, you can jump into any of them with one click and apply things in bulk.
It is created free in a matter of minutes, with a Google email different from the one used by the accounts it will manage. An MCC can contain ordinary accounts and also other MCCs (sub-managers), forming a hierarchy.
When do you need an MCC?
- You manage two or more accounts (even if they belong to the same company).
- You are an agency or freelancer: one MCC per agency, with the clients' accounts linked to it.
- You want lists shared across accounts: negatives, site exclusions, audiences.
- You want consolidated reports across several accounts.
- You want to run scripts across several accounts at once (an MCC script walks through every linked account in a single run).
If you have a single account and nobody else touches it, you do not need one. Yet.
What access levels exist and which should you grant?
Two different planes that are constantly confused:
User access to ONE account
Every Google Ads account has users with a level:
| Level | Can |
|---|---|
| Admin | Everything, including adding and removing users and linking MCCs |
| Standard | View and edit campaigns; does not manage users |
| Read only | View reports, change nothing |
| Email only | Receive notifications |
| Billing | View and edit the payment details |
Linking an MCC to an account
An MCC does not "log in" as a user: it is linked to the account (the account accepts the request) and from then on the MCC's users access it with the level they hold within the MCC (admin, standard, read only, email only, billing). One account can be linked to several MCCs at once: yours and your agency's, for example.
Who should own the account, the client or the agency?
The most expensive mistake made with agencies and freelancers is letting them create the account. If the account is born inside the agency's MCC, with its email and its payment method, the account belongs to the agency: the history, the accumulated Quality Score, the remarketing lists, the conversions. When the relationship ends, either they hand it over (if they feel like it) or you start from scratch.
How to do it properly, whichever side you are on:
- The advertiser creates and pays for the account, using a company Google email (not an employee's personal one) and with two people as admins (if one leaves, the other is still in).
- The agency works by linking its MCC to the account. Never with the client's password.
- When you change agency: unlink the old MCC and link the new one. Two clicks, nothing lost.
- Review the list of users and linked MCCs every few months: access left behind by people who are no longer around is the most common door to trouble.
- Two-step verification made compulsory for every user with write access. Google lets you require it from the account's security settings.
What does an MCC NOT do?
- It does not share the budget across accounts: each account pays its own way.
- It does not merge conversion data across accounts (cross-account conversion tracking from the MCC does exist, but you have to switch it on deliberately).
- It does not replace each account's own structure: an MCC full of messy accounts is mess at scale.
💡 Ninja trick: the MCC is the natural habitat of scripts. The whole Ninja Scripts Suite can run from an MCC and walk through the linked accounts on every run: one script watches the budget of 30 accounts, another reviews their search terms, another their Display placements. It is the difference between managing accounts one at a time and managing a fleet. And the code never leaves the MCC: the client sees the results in their spreadsheet, not the script.
What you should remember
- The MCC groups accounts: for multiple accounts, agencies, shared lists, consolidated reports and scripts run in bulk.
- Two planes of access: users on an account and linked MCCs.
- The advertiser creates and pays for the account; the agency links to it. Never the other way round.
- Two admins, two-step verification and a periodic review of who has access.
