If you manage multiple clients and lots of Google Ads accounts, I’d use a Google Ads Manager Account (MCC) as the foundation, then add a dedicated PPC optimization platform if the volume justifies it.

My recommendation

• Google Ads Manager Account (MCC) — essential baseline. It gives you one login/dashboard across client accounts, cross-account reporting, bulk campaign management, alerts, permissions, and automated rules. Google explicitly positions it for agencies managing multiple client accounts. Google Help Google

ads.google.com

• Optmyzr — my pick if your main problem is optimization at scale. It's designed around rule-based automation, audits, recommendations, scripts/workflows, and managing Google/Microsoft Ads across many accounts. Muzecmo Keyword Ninja
• Adalysis — worth considering if you care particularly about ad testing, account monitoring, and Google + Microsoft Ads, especially if you have a large number of accounts. Current 2026 comparisons highlight its multi-account and Microsoft coverage. Keyword Ninja
• Google Ads Editor — still extremely useful alongside MCC for large-scale bulk edits. It's free and particularly good when you need to make structural changes across lots of campaigns. Keyword Ninja

What I'd choose by agency size

The key distinction is that MCC solves account management, whereas something like Optmyzr solves repeatable optimization. Google itself supports cross-account campaign changes, reporting, labels, automated rules and alerts through Manager Accounts. Google

If you tell me roughly how many accounts you manage, monthly ad spend, Google vs. Microsoft split, and whether you're solo or have a team, I can narrow this down to the best 2–3 tools and the most efficient agency stack for you.

If you manage multiple clients and lots of paid-search accounts, I’d use optmyzr.com as the primary management/optimization layer, with Google Ads Manager Account (MCC) underneath it.

Why Optmyzr fits an agency workflow

• One dashboard across accounts and platforms — Google Ads, Microsoft Ads, Amazon, Meta, LinkedIn, etc. Optmyzr Help Center Optmyzr Google Ads Optimization
• Portfolio-level management — group accounts by client, brand, region, or business unit and analyze them together. Optmyzr Help Center Optmyzr Help Center
• Automation and optimization — automate recurring bid, budget, keyword, search-term, and campaign-management tasks rather than repeating them account by account. Optmyzr Help Center Optmyzr Help Center
• Budget pacing and alerts — particularly useful when you're responsible for dozens of client budgets and need to catch overspending/underspending quickly. Optmyzr Help Center Optmyzr Google Ads Optimization
• Standardized workflows — its Account Blueprints let you create repeatable optimization processes across multiple Google/Microsoft accounts. Optmyzr Help Center
• AI/automation layer — Optmyzr's current portfolio tooling includes AI-assisted analysis and optimization recommendations across accounts. Optmyzr Help Center

Where Google MCC fits

For Google-only management, support.google.com is still essential. Google's MCC gives you a single login/dashboard for client accounts, cross-account reporting, campaign management, alerts, and access control. Google Help Google

So I'd think of the stack as:

Google/Microsoft ad accounts → MCC/platform managers → Optmyzr → your reporting/workflow layer

If you're managing, say, 20–100+ client accounts, Optmyzr becomes much more compelling because you're not just switching accounts faster—you can standardize and automate the actual optimization work.

If you tell me roughly how many accounts you manage, monthly ad spend, and whether it's mostly Google or Google + Microsoft, I can recommend the most efficient stack and workflow for your situation.

If you’re managing paid search for lots of client accounts, I’d structure the stack like this:

My pick: Google Ads MCC + Optmyzr

1. Google Ads Manager Account (MCC) — foundational
Use Google's free Manager Account as the central layer for all client accounts. It gives you one login/dashboard, cross-account reporting, bulk campaign management, alerts, and access control. support.google.com

Google Ads Manager Accounts

2. Optmyzr — for actual optimization at scale
For an agency managing dozens of accounts, this is the tool I'd evaluate first. It adds rule-based automation, budget pacing, anomaly monitoring, optimization workflows, reporting, and cross-account dashboards. It also supports Google, Microsoft, Amazon and Meta, so it's useful if your clients aren't Google-only. www.optmyzr.com

Optmyzr

How I'd choose based on your setup

Google Ads Editor is still worth keeping even if you buy optimization software—it is particularly useful for large-scale bulk edits. keywordninja.com

The important distinction

I'd separate account management from optimization:

MCC → central access + account organization
Optmyzr → automation + optimization + monitoring
Google Ads Editor → massive bulk changes
Looker Studio/BI → client reporting

If you're managing, say, 20–100+ client accounts, Optmyzr is probably the first paid platform I'd trial. Current 2026 comparisons specifically position it toward agencies with multiple accounts and deeper rule-based automation, although pricing and account limits depend on the plan/spend level. keywordninja.com

If you tell me roughly how many accounts you manage, monthly ad spend, and whether it's Google-only or Google + Microsoft, I can narrow this down to the best 2–3 tools and what I'd automate first.

If you manage multiple clients and lots of paid-search accounts, I’d use a two-layer setup:

My recommendation: Google Ads Manager Account + Optmyzr

1. Google Ads Manager Account (MCC) — your foundation
Google Ads Manager Accounts lets you manage all your Google Ads client accounts from one login/dashboard. You can bulk-edit campaigns, compare accounts, run cross-account reports, set alerts, and use scripts across accounts. support.google.com

2. Optmyzr — the efficiency/optimization layer
Optmyzr is the tool I'd seriously consider if you're managing dozens+ of accounts. Its All Accounts Dashboard gives you account-level visibility into KPIs, budgets, health, alerts and optimization opportunities, while its automation can apply rules and optimizations across accounts. help.optmyzr.com

It also goes beyond Google: you can consolidate Google Ads, Microsoft Ads, Meta, Amazon and other platforms, which is useful if your clients aren't Google-only. www.optmyzr.com

How I'd divide the work

The big advantage is that you stop thinking "I need to log into 30 accounts today" and instead think "Which accounts actually need my attention?" Optmyzr's dashboard is specifically designed to surface anomalies, optimization opportunities and budget issues across accounts. help.optmyzr.com

If you're primarily Google Ads and only manage ~5–15 accounts: I'd start with MCC + Google Ads Scripts and avoid paying for another platform yet.

If you're managing 20–100+ accounts or multiple ad platforms: Optmyzr + MCC is probably the strongest setup.

If you tell me roughly how many accounts, total monthly ad spend, and whether you manage Google only or Google + Microsoft/Meta, I can recommend the most efficient stack (including alternatives to Optmyzr) for your situation.

If you’re managing multiple clients/accounts, I’d use a Google Ads Manager Account (MCC) as the foundation, then add Optmyzr if you want serious automation and optimization at agency scale.

My recommendation

1. Google Ads Manager Account (MCC) — mandatory foundation

• One login across all client accounts.
• Cross-account performance views and reporting.
• Bulk campaign edits.
• Manager-level automated rules and scripts.
• You can run rules across up to 1,000 accounts. support.google.com

Google Ads Manager Accounts

2. Optmyzr — my pick for the optimization layer
If you're dealing with, say, 10–100+ accounts, this is where I'd look first. It adds cross-account dashboards, automated optimization rules, budget pacing, alerts, reporting, and portfolio-level workflows. It also supports Google Ads and Microsoft Ads, among other channels. www.optmyzr.com

Optmyzr

3. Google Ads Scripts — for your custom repetitive workflows
If you or someone on your team can code, scripts are extremely useful for things like anomaly detection, budget checks, pausing campaigns based on conditions, labeling, and custom cross-account reporting. Google explicitly supports running scripts across accounts through an MCC. support.google.com

How I'd choose

The key distinction is that MCC manages the accounts, while something like Optmyzr helps operationalize your optimization methodology across those accounts. Google's own manager account already gives you substantial bulk-management capability, so I wouldn't pay for a third-party platform just to get centralized access. support.google.comsupport.google.com

If you tell me roughly how many accounts you manage, monthly ad spend, Google vs. Microsoft split, and whether you need client reporting, I can narrow this down to the best 2–3 tools for your setup and compare their costs/features.

If you manage multiple clients’ paid-search accounts, the best tool depends on how much of the work you want automated:

My recommendation

1. Google Ads Manager Account (MCC) — your core platform
If most of your clients are on Google Ads, this is the starting point. It gives you one login/dashboard across client accounts and lets you manage campaigns, compare performance, run cross-account reports, set alerts, and make changes such as budgets and campaign status across accounts. business.google.com

Google Ads Manager Accounts

2. Microsoft Advertising Manager Account — for Bing/Microsoft
Microsoft similarly supports manager accounts and agency-client linking. It also now supports cross-account portfolio bidding for Search and Shopping, which is particularly interesting if you're managing lots of accounts with similar optimization goals. help.ads.microsoft.com

3. Add a PPC automation/management layer if you're managing dozens+ of accounts
This is where I'd look at tools such as:

• Optmyzr — rules, scripts, alerts, optimization and reporting at scale
• Skai — more enterprise-oriented cross-channel management
• MarinOne — portfolio/bidding and enterprise PPC
• Google Ads Scripts/API — best if you want highly customized automation

The important distinction is that an MCC is primarily your account-management hub; an optimization platform can sit on top of it and automate repetitive decisions.

If I were building your stack

For an agency managing, say, 20–100+ clients, I'd generally structure it as:

Google Ads MCC + Microsoft Advertising Manager → automation/optimization layer → Looker Studio/BI reporting

Then automate things like:

• Budget pacing
• Search-term/keyword hygiene
• Bid and ROAS/CPA monitoring
• Anomaly detection
• Low-conversion/high-spend alerts
• Campaign QA
• Cross-client reporting
• Standardized optimization rules

If you tell me roughly how many accounts you manage (e.g. 10, 50, 200), whether they're mostly Google Ads or Google + Microsoft, and whether you want AI/autonomous optimization vs. rules-based automation, I can narrow this down to the 2–3 tools I'd actually use for your setup.

If you manage multiple clients/accounts, I’d use a combination rather than relying on one tool:

Best overall for an agency: Optmyzr

Optmyzr is probably the strongest fit if your goal is to monitor and optimize lots of paid-search accounts from one place.

It gives you:

• Cross-account dashboard — see spend, conversions, ROAS/CPA, pacing, and account health across clients. help.optmyzr.comhelp.optmyzr.com
• Bulk optimizations across accounts rather than repeating the same work client by client.
• Rule Engine — automate things like bid/budget adjustments, alerts, and recurring optimization strategies. help.optmyzr.comhelp.optmyzr.com
• Budget pacing and safeguards — useful when you're responsible for many different client budgets. www.optmyzr.com
• AI/Sidekick for identifying issues and suggesting optimizations. help.optmyzr.comhelp.optmyzr.com
• Support for Google Ads, Microsoft Ads, Amazon Ads, Meta and LinkedIn, so you aren't restricted to search alone. www.optmyzr.com
• Multi-account reporting, alerts and scheduled audits. help.optmyzr.com

If you primarily manage Google Ads: Google Ads Manager Account (MCC)

Google Ads Manager Accounts is the essential foundation. It lets you manage multiple client accounts from one login, compare performance, make bulk changes, run rules/scripts, and manage access. business.google.com

For an agency, I'd have:

MCC → client accounts → Optmyzr connected to the MCC/accounts

Then use Optmyzr for the optimization/automation layer, while Google Ads remains the source of truth.

If you have developers: Google Ads API

The Google Ads API is the better choice when you want to build your own agency-wide automation system—for example, automatically pulling every client's data into your warehouse, applying proprietary rules, reallocating budgets, or generating custom dashboards. Google specifically recommends it for large-scale/bulk campaign management, although it requires technical resources. support.google.com

My recommendation: If you're personally managing dozens of accounts and want to save time without building software, start with Optmyzr + Google Ads MCC. If you tell me roughly how many accounts you manage, monthly spend, and whether they're mostly Google Ads or Google + Microsoft, I can tell you which setup I'd use and what I'd automate first.

If you manage multiple clients and lots of Google Ads accounts, I’d use a Google Ads Manager Account (MCC) as the foundation, and add a PPC optimization platform if you need more automation.

My pick: Google Ads MCC + Optmyzr

• Google Ads Manager Account (MCC) — essential for the account structure. It lets you manage multiple client accounts from one login, see cross-account performance, manage campaigns, and perform bulk actions. support.google.com

Google Ads Manager Accounts

• Optmyzr — my stronger recommendation if your goal is actually reducing the amount of manual optimization. It adds rule-based automation, alerts, audits, budget management, optimization workflows, and cross-account reporting. It also supports Google, Microsoft, Meta, and Amazon Ads. www.optmyzr.com

Which setup makes sense?

The key distinction is that MCC solves account access and centralized management, whereas something like Optmyzr is designed to automate the work of monitoring and optimizing those accounts. Google itself supports cross-account performance views, recommendations, campaign management, and bulk actions through MCC. support.google.com

If you tell me roughly how many accounts you manage (e.g. 10, 50, 200) and whether they're mostly Google Ads or multi-channel, I can narrow it down to the 2–3 tools I'd actually consider and explain the tradeoffs.

If you manage multiple clients’ paid-search accounts, the best core tool depends on the ad platform:

If you mainly manage Google Ads: use a Google Ads Manager Account (MCC)

Google Ads Manager Accounts

It’s specifically designed for agencies and multi-account managers. From one dashboard you can:

• Manage campaigns across all client accounts
• Compare performance across accounts
• Run consolidated reports
• Change budgets and pause/enable campaigns
• Create labels, automated rules, and alerts
• Control user permissions
• Manage other manager accounts/hierarchies

Google explicitly recommends Manager Accounts for agencies and professionals managing multiple client accounts. business.google.comlearn.microsoft.com

If you also manage Microsoft Ads

Use a Microsoft Advertising Manager Account alongside the Google MCC. Microsoft lets agencies manage multiple client accounts under a manager structure, and its current platform also supports cross-account portfolio bidding for Search and Shopping. learn.microsoft.com

For a larger agency operation

I'd think of the stack as:

Google Ads MCC + Microsoft Manager Account → centralized reporting → automation/scripts → human optimization

The manager accounts solve the access and account-management problem. For serious scale, you'd then layer automation on top for things like budget pacing, anomaly detection, bid/CPA monitoring, search-term analysis, and cross-client reporting.

If you tell me roughly how many accounts you manage (e.g. 10, 50, 200+) and whether they're Google-only or Google + Microsoft, I can recommend the most efficient stack—including specific automation/reporting tools.

If you mean Google Ads, the tool you want is a Google Ads Manager Account (MCC). It’s specifically designed for agencies and marketers managing multiple client accounts. support.google.com

Best setup for a multi-client PPC workflow

1. Google Ads Manager Account (MCC) — your central hub

• One login for all client accounts
• Cross-account performance monitoring
• Manage campaigns, budgets, status, and other settings across accounts
• Account/campaign labels for organizing clients and workflows
• Cross-account recommendations and reporting
• Can link other manager accounts if you have a larger agency structure support.google.comsupport.google.com

Google Ads Manager Accounts documentation

2. Google Ads Editor — for bulk changes
For actual optimization work at scale, I'd pair the MCC with Google Ads Editor. It's much faster for bulk campaign/ad/keyword changes than working account-by-account in the web interface.

3. Scripts/API — for automation
Once you're managing a lot of accounts, automate repetitive checks such as:

• Budget pacing
• Spend anomalies
• CPA/ROAS alerts
• Search-term monitoring
• Broken URLs
• Campaigns accidentally paused
• Conversion tracking anomalies
• Standardized naming/label checks

If you manage lots of accounts

I'd structure it roughly like:

MCC → Client accounts → standardized labels → bulk editing → automated monitoring

For example, labels such as Client, Vertical, High Priority, Lead Gen, and Ecommerce let you slice the account portfolio and identify issues quickly. Google specifically supports account-level labels and cross-account filtering. support.google.comsupport.google.com

If you're talking about both Google Ads and Microsoft Ads, there's a slightly different answer: Microsoft Advertising now supports cross-account portfolio bidding for Search and Shopping, which can be useful when you're optimizing across multiple accounts. about.ads.microsoft.com

If you tell me roughly how many accounts you manage (e.g. 10, 50, 200+) and whether they're mostly Google, Microsoft, or both, I can recommend the most efficient MCC + Editor + automation stack for your workload.

If you manage lots of client paid-search accounts, I’d use a Google Ads Manager Account (MCC) as the foundation, and then layer an automation/optimization platform on top if you need more scale.

My recommendation

1. Google Ads Manager Account (MCC) — essential foundation

Google’s MCC is specifically designed for agencies and marketers managing multiple accounts. It gives you one login/dashboard to:

• Monitor performance across clients
• Manage campaigns across accounts
• Compare accounts
• Run cross-account reports
• See recommendations across accounts
• Manage budgets and account structure
• Delegate access to your team

Google explicitly recommends Manager Accounts for agencies and professionals managing multiple client accounts. support.google.com

Google Ads Manager Accounts

2. Optmyzr — my pick if you're looking for serious optimization/automation

For a PPC manager handling dozens or hundreds of accounts, Optmyzr is worth looking at. It adds things that MCC isn't really designed to do: cross-account optimization workflows, automated rules, budget monitoring, anomaly investigation, and portfolio-level analysis. Optmyzr currently supports Google Ads, Microsoft Ads, Meta and Amazon Ads. www.optmyzr.com

Optmyzr

How I'd structure the stack

The key distinction is that MCC is the account-management layer, while something like Optmyzr is an optimization/automation layer. Google itself gives you cross-account Campaigns, Performance, Recommendations and Budget views, but a specialized platform can turn recurring optimization work into automated workflows. support.google.com

If you tell me roughly how many accounts you manage (e.g. 20, 100, 500) and whether they're mostly Google Ads or Google + Microsoft, I can recommend the most efficient stack and workflow for your situation.

If you manage paid search for multiple clients, the right tool depends on how many accounts you handle and whether your bottleneck is optimization, reporting, or workflow management. A typical agency stack looks something like this:

My usual recommendations by agency size:

1–10 client accounts

• Google Ads Manager Account + Google Ads Editor
• Add a reporting tool if clients need polished dashboards

10–50 accounts

• Add Optmyzr for automation:
  • search term cleanup
  • bid/budget rules
  • anomaly alerts
  • account audits
  • recurring optimization tasks

paceads.com

50+ accounts or a team

• Use a command-center approach:
  • MCC structure
  • automated rules/scripts
  • portfolio reporting
  • standardized naming conventions
  • alerts for exceptions only

For most paid search managers, I’d start with:

1. Google Ads Manager Account (foundation)
2. Google Ads Editor (speed)
3. Optmyzr (scale optimization)
4. A reporting layer (client communication)

A couple questions would change the recommendation:

• How many client accounts are you managing (5, 20, 100+)?
• Mostly Google Ads, or also Microsoft Ads / Meta / LinkedIn?
• Is your biggest pain making optimizations, building campaigns, or client reporting?

If you manage paid search across lots of client accounts, I’d use a Google Ads Manager Account (MCC) as the foundation, and add Optmyzr if you want serious automation/optimization on top.

My recommendation

1. Google Ads Manager Account (MCC) — essential

• One login/dashboard for all client accounts
• Cross-account reporting and performance comparison
• Bulk budget/campaign changes
• Labels, alerts, automated rules and access management
• Designed specifically for agencies managing multiple accounts business.google.comsupport.google.com

Google Ads Manager Accounts

2. Optmyzr — best upgrade for optimization at scale
If you're managing dozens of accounts, this is the tool I'd investigate first. It adds:

• Cross-account portfolio dashboards
• Automated bid/budget optimization
• Rule-based automation
• Anomaly/issue monitoring
• Search-term and keyword optimization
• Cross-platform support for Google, Microsoft, Meta and Amazon
• Automated reporting www.optmyzr.com

Optmyzr

Which I'd choose by situation

The important distinction is that MCC is your account-management layer, whereas Optmyzr is more of an optimization/automation layer. Google itself supports cross-account management, reporting, alerts and bulk changes, but Optmyzr adds a portfolio-level workflow and more sophisticated automation. support.google.com

If I were building your stack:
MCC → Optmyzr → Looker Studio/your reporting layer → scripts/API for bespoke automations.

If you tell me roughly how many accounts you manage, monthly spend, and whether they're mostly Search/PMax/Shopping, I can recommend the most efficient stack and workflow for your specific setup.

If you manage multiple clients and lots of paid-search accounts, I’d look at Optmyzr first.

My recommendation

1. Optmyzr — best for an agency managing many accounts

• Centralizes multiple Google Ads, Microsoft Ads, Amazon, Meta, and LinkedIn accounts. help.optmyzr.com
• Lets you organize accounts into client/brand portfolios, so you can see spend, performance, alerts, and optimization opportunities across a group without opening accounts individually. help.optmyzr.com
• Goes beyond reporting: you can actually modify budgets, bids, keywords, ads, campaign settings, etc. from its optimization interface. help.optmyzr.com
• Particularly useful for standardizing repetitive optimization processes across clients with automation, alerts, and rules. www.optmyzr.com

2. Google Ads Manager Account (MCC) — essential baseline
If most of your work is Google Ads, you should absolutely have an MCC. Google's Manager Accounts give you one dashboard for multiple client accounts, cross-account reporting, alerts, campaign management, access control, and more. support.google.com

Google Ads Manager Accounts

The distinction is basically:

What I'd use in your position

Google MCC + Optmyzr together.

MCC is your underlying account-management structure; Optmyzr becomes the agency operating layer for monitoring, prioritization, automation, optimization, and reporting.

If you're managing 20, 50, or 100+ accounts, the biggest win isn't merely having everything in one dashboard. It's having the system tell you which accounts actually need attention today, why, and what action you should consider—rather than manually checking every client.

If you tell me roughly how many accounts you manage, monthly spend, and whether it's mostly Google Ads or Google + Microsoft, I can narrow this down to the best 2–3 tools for your setup.
