Why an MCC changes what you need from a tool
A manager account (MCC) gives one login to many client accounts. That is convenient for you and awkward for negative keyword work, because the search terms and the damage are different in every account. Lists you maintain by hand drift apart. Every new client means rebuilding the same junk-term list from memory, and the clients you reviewed last month quietly fall behind.
The question is not whether a tool can find wasted queries. Any tool can sort a report. The question is whether it fits how an agency actually works: many accounts, one reviewer, and clients who ask what changed. That is where the five requirements below come from.
Five requirements for MCC based work
1. Access through the manager login. You should connect the accounts you already manage, with the permission level you already hold, instead of asking each client for new credentials. Check that you can disconnect one client without touching the rest.
2. A shared layer and a client layer. Some exclusions are wrong for every client in a vertical, such as job seekers and DIY. Others are client specific, such as a competitor name that converts for one client. The tool needs shared lists across accounts for the first group and per-account review for the second. The multi-location page uses the same two layers.
3. A conflict check per client. A negative that is safe in one account can block the best converting query in another. The tool must test every proposed exclusion against that account's own converting terms and show the hit before you approve it.
4. Approval and a log you can show a client. When a client asks why leads dropped, you need the date, the term, the reason and a one click undo. Silent auto-apply fails this test. The scripts versus software comparison covers why.
5. Flat pricing by account count, not by ad spend per client. Agencies grow by adding small accounts. A tool priced by percentage of spend punishes that. A plan that states connected accounts and a spend ceiling in advance lets you price your own service without surprises.
What it costs by account count
These are the published plans. Compare them with what you charge for the same work.
| Client accounts | Plan | Price per month | Cost per account | Shared lists |
|---|---|---|---|---|
| 1 | Starter | 49 USD | 49 USD | No |
| 5 | Growth | 149 USD | about 30 USD | Yes |
| 20 | Agency | 499 USD | about 25 USD | Yes |
| 50 | Agency | 499 USD | about 10 USD | Yes |
Starter covers one account with up to 10,000 USD of monthly spend, Growth covers 5 accounts up to 75,000 USD, and Agency covers 50 accounts up to 500,000 USD and adds Microsoft Advertising and Amazon Ads. Annual billing lowers each price, and the pricing page lists all of it. For the cost of the same work done by people, see negative keyword management service versus software.
A worked example with an agency of 12 clients
An agency manages 12 local service clients under one MCC. A junior spends 25 minutes per client per week on search terms, so 12 x 25 = 300 minutes, or 5 hours a week. At an internal cost of 40 USD an hour that is about 200 USD a week, 800 USD a month, and the quality depends on who is rushed that Friday. This is an illustrative setup, so substitute your own times.
On the Agency plan at 499 USD a month, the review shrinks to confirming ranked proposals. Even if that only halves the time, the saving of roughly 400 USD a month is close to the plan price, and the real gain is that all 12 accounts get the same checks on the same day with a log per client. If the waste found in the first export is already larger than a month of the plan, the answer is clear before you pay. Run that export through the demo.
The same routine appears in the client onboarding guide, which describes the first-week list build for a new account. If your agency also sources creators for client social campaigns, directories such as Ugcagencies help you compare partners, a separate job from search term control.
Three mistakes agencies make with MCC tools
Copying one client's list to all. It saves ten minutes and blocks real demand. Share only families that cost money in several accounts with no conversions.
Reviewing everything at the same depth. A 500 USD a month account and a 20,000 USD account should not get equal time. Sort by cost and start at the top, which is what a ranked queue does.
Skipping the audit trail. Clients accept an exclusion they were told about. They do not accept one they discover. Keep the log and mention it in the monthly report. Google documents the underlying features in its negative keywords help and its manager account guide.
Questions agencies ask
Can a negative keyword tool work under a manager account? Yes, when it connects the accounts you manage. NegativeKeywords connects client accounts through authorization you control, and you can disconnect any single client without affecting the others.
Can I share one negative list across client accounts? On Growth and above, yes. Shared lists hold terms that are junk across clients. Client specific terms stay in each account and pass a conflict check against that client's converting queries first.
How many accounts can one subscription cover? Starter covers 1, Growth 5, Agency 50, and Enterprise is unlimited. If you manage more than 50, Enterprise removes the account limit and adds team access controls.
Will clients see what changed? Every approved exclusion is logged with date, reason and account, and can be undone. Agencies use the log in monthly reports, and the white label reports page shows how it is presented.
