How to Manage Multiple Google Ads Accounts
The short answer
To manage multiple Google Ads accounts, keep each business or client in its own account and reach them all through one Google Ads manager account (often called an MCC), so one sign-in opens every account and you can compare them side by side. Then work through a short daily routine that looks at every account but only acts on the few that need attention.
Separate logins work for two or three accounts. Beyond that, switching between them costs more time than the work itself, and problems in a quiet account go unnoticed. This guide compares the options, lists Google's limits and gives you a routine that holds up at ten or fifty accounts.

What are your options?
| Option | How it works | Good for | Weak spot |
|---|---|---|---|
| Separate logins | Each account has its own users; you switch accounts in Google Ads | Two or three accounts you own | One email address can be associated with at most 20 Google Ads accounts; no cross-account view |
| Manager account (MCC) | A Google Ads account that links to other accounts and manages them | Agencies, in-house teams with several brands, anyone over a handful of accounts | Still one account at a time for most work; reports across accounts take setup |
| A tool on top of Google Ads | Reads every account through the Google Ads API and shows them together | Daily triage across many accounts | One more tool; check what it can change and how it records changes |
Most people who run many accounts use both of the last two: a manager account for access and billing, and a cross-account view for the daily check.
What is a Google Ads manager account?
A manager account is a Google Ads account that lets you view and manage multiple Google Ads accounts, including other manager accounts, with one sign-in. You do not run ads in it directly; you use it to reach the accounts below it. According to Google's help, a manager account lets you:
- compare performance across all linked accounts and run reports for several accounts at a time,
- create and manage campaigns in the linked accounts,
- give people access to many accounts at once, at different access levels,
- set up consolidated billing or monthly invoicing for linked accounts (monthly invoicing requires a manager account).
A manager account is a new account you create, not an upgrade of an existing one. Linking an account does not change it: its history stays intact, its existing users keep their access and its billing stays with them unless you set up consolidated billing. The manager does not get administrative ownership of the client account unless the client turns it on.
What are Google's limits?
| Limit | Value | Source |
|---|---|---|
| Google Ads accounts per email address | 20, manager accounts included | Google Ads Help: About manager accounts |
| Non-manager accounts linked to one manager | 85,000, active and inactive | Google Ads Help: Account limits for manager accounts |
| Active accounts, top-level manager, highest monthly spend under $10,000 in the last 12 months | 50 | Same |
| Active accounts, highest monthly spend $10,000 to under $500,000 | 2,500 | Same |
| Active accounts, highest monthly spend over $500,000 | No active-account limit | Same |
| Manager accounts that can manage one account | 5 | Google Ads API: System limits |
| Levels in a hierarchy, top manager to bottom account | 6 | Same |
As of October 2026. The active-account limit is the one small agencies hit first: canceled accounts do not count toward it, so cancel accounts you no longer use instead of leaving them linked and idle.
How do you link existing accounts to a manager account?
- Create the manager account. Use a shared work address that will outlive any one employee, not a personal one.
- Find the client's Customer ID. It is the ten-digit number at the top of their Google Ads account (format 123-456-7890).
- Send the link request. In the manager account, select the Accounts icon, then Sub-account settings. Click the plus button, choose Link existing account, enter the Customer ID (one per line for several accounts), select Preview, then Send request.
- The account accepts. Someone with access to the client account goes to Admin › Access and security, opens the Managers tab and, under the link request, chooses Accept. The invitation email has an accept link too.
- Check access levels. Decide who on your side needs Admin and who needs Standard or Read-only access.
Google Ads has five access levels for users:
| Access level | Can do |
|---|---|
| Admin | Everything, including managing users, manager links and product links |
| Standard | View and edit campaigns; no user management |
| Read-only | View campaigns and run reports, no changes |
| Billing | Manage billing and payments only |
| Email-only | Receive notification emails and reports |
For agencies: let the client own their account and link it to your manager account, rather than creating the account inside your manager. If you part ways, the link is removed and the client keeps everything.
How do you keep track of many accounts every day?
The problem with many accounts is not the work in each one. It is noticing which account needs work today. A routine that scales looks at every account and acts on few:
- Spend against budget. For each account, is month-to-date spend in line with the monthly target? An account far ahead will run out early; one far behind is probably limited somewhere.
- Anything that stopped. Disapproved ads, campaigns not serving, a payment problem, or conversions that fell to zero overnight, which usually means broken tracking rather than a bad day.
- Big moves in cost per result. Compare the last 7 days with the 7 before. A jump in cost per conversion or cost per click is worth a look; small movements are noise.
- Only then, the details. Open the few accounts that failed one of the checks above. Leave the rest alone today.
- Once a week, search terms. Waste builds up slowly. How to find wasted spend in Google Ads covers the weekly check.
Keep the same order every day and you will see the exceptions faster. Two habits help:
- Name things the same way in every account, for example Brand – Search, Service – Search, so a list of campaigns from twenty accounts is readable at a glance.
- Write down every change with the reason. With several people and many accounts, "who changed this budget and why" comes up every week. Google Ads keeps a change history per account; a shared note of the reason saves the conversation.
When are separate logins still fine?
A manager account is not always worth it. Keep it simple if:
- you run two or three accounts you own and look at them together anyway,
- each account is managed by a different person who never needs the others,
- the client insists on adding you as a user directly. That works; you just lose the cross-account view.
Move to a manager account when you start forgetting to check an account, or when people join and leave your team often enough that adding and removing users account by account becomes a job of its own.
