My Client Center, commonly known as an MCC, is an overall account used to manage multiple Google Ads accounts without constantly logging in and out of each Google Ads account. It features a linking system that allows regular accounts to be connected to this single “umbrella” account without exchanging login details.
It is a powerful tool when the management of multiple accounts is required. Ideally, it is helpful for large advertisers with more than one Google Ads account. Still, it is commonly used by third-party agencies that manage accounts for several of their clients.
Key features include the ability to view information for all managed accounts in one place, manage those accounts easily due to a single login, and run reports across all accounts at once.
If you are currently wasting time and becoming frustrated due to switching between accounts, then using MCC can make life easier. For example, an SEM company would have difficulty operating without using an MCC when multiple client accounts need to be managed.
