Google Ads Merchant Center for Agencies: What It Is and How to Set It Up

If you manage Shopping campaigns for more than a handful of ecommerce clients, you already know the pain. Logging in and out of individual Merchant Center accounts. Checking feed health one client at a time. Discovering a product disapproval only after a client asks why their ROAS dropped. For years, Google gave agencies an MCC-like experience on the ads side but left them navigating Merchant Center the hard way - account by account, tab by tab.

On March 11, 2026, Google officially launched Merchant Center for Agencies as a generally available product in the United States and Canada.

This is a dedicated, agency-first command center built specifically for teams managing multiple Google Merchant Center accounts at scale. And it changes how agency teams handle the entire feed management layer of Shopping and Performance Max campaigns.

Google reports that agencies using the platform can save up to 12 hours per week through the simplified single-view interface.

Socium Media, which piloted the product ahead of the 2025 holiday season, reported 50% faster resolution on monitoring tasks. Those are not theoretical projections - they're measured results from a real agency running real campaigns during peak retail.

What Merchant Center for Agencies Actually Is

Let's be precise about what this product does, because the name alone creates confusion. You get an agency account that overlays all of your clients' individual Merchant Center accounts in one interface. It replaces the old Multi-Client Account (MCA) system, which offered basic multi-account access but no portfolio-level tools.

Think of it this way: performance marketer Benedek Viniczai described it as "Merchant Center getting an MCC-like brain." If you've used the Google Ads MCC (My Client Center) to manage multiple ad accounts from a single dashboard, the analogy is exact. It's an MCC account, but for product feeds instead of ad campaigns.

The platform is available to agencies managing Merchant Center accounts for other businesses. It's not available to merchants managing their own store. That distinction matters. This isn't a rebranded MCA that anyone can request. It's built for a specific workflow: agencies overseeing client portfolios.

Who Can Access It Right Now

As of March 2026, Merchant Center for Agencies is generally available in the United States and Canada and available as a pilot globally.

Google has not announced a specific timeline for expanding general availability beyond the US and Canada, but the global pilot structure suggests broader availability is the intended direction.

Agencies outside the US and Canada can request pilot access through the official Contact Us form on Google Merchant Center support.

There's no self-serve activation. Every agency - whether in the US or applying to the global pilot - must submit a request and be approved.

How It Differs from the Old Multi-Client Account (MCA)

This comparison trips up experienced PPC practitioners who managed client feeds through the MCA structure for years. Merchant Center for Agencies is not simply a renamed MCA. While the structures share some similarities - both provide a parent-level view over child accounts - the new platform adds agency-specific workflow tools that the MCA never offered.

The MCA was designed for account structure management. Merchant Center for Agencies is designed for agency workflow management - a meaningful distinction for teams whose daily operations involve monitoring, diagnosing, and optimizing across many client accounts simultaneously.

Here are the practical differences:

• Cross-account diagnostics with prioritization.

The diagnostics page lets you prioritize fixes based on "click potential," which estimates how many more clicks you could get by resolving an issue. The old MCA showed you account-level metrics but never helped you triage issues by business impact. - Client optimization tools. You can create and monitor promotions by filtering for specific merchants and organizing schedules by status, and address inventory gaps by monitoring out-of-stock products across your merchant portfolio using the "Share report" feature to notify clients of restocking needs.

• Ads Opportunities with labeling.

Agencies can label identified low-traffic products directly within Merchant Center and export those labels into a supplemental data source, which then flows through to Google Ads.

• Team-level workflow.

User permissions for each client account can be managed from the central All Client Accounts page. Account managers can be assigned specific clients, issues can be delegated to team members, and leadership can monitor portfolio-level status from the Agency Overview page.

The old MCA also carried real operational risk for agencies. Having all accounts linked to one MCA created a higher chance of multiple account suspensions due to all being linked. Having multiple similar niches in one MCA could also cause suspensions. Experienced feed management specialist Emmanuel Flossie of FeedArmy, who manages over 200 linked accounts, has long recommended that clients should always own their own accounts - never the agency. Merchant Center for Agencies does not directly address the super admin vulnerability but does offer agencies a structured operational environment that is separate from the administrative chaos that can emerge in shared-access MCA setups.

The Five Core Sections of the Interface

The platform has five primary sections: All Client Accounts, Agency Overview, Diagnostics, Client Optimization, and Ads Opportunities. Each serves a distinct operational purpose.

All Client Accounts

Your agency account serves as a central hub for managing all your client accounts and user permissions from one place. The all client accounts page provides a centralized view to help you organize and monitor your client accounts.

From this page, you can star important accounts for quick access and customize which accounts are visible in your list.

This is your home base. If you manage 30 ecommerce clients, you'll see all 30 listed with status indicators, and you can star the five biggest accounts for immediate access every morning.

Agency Overview

The agency overview page provides a portfolio-level snapshot. It surfaces summary statistics on account statuses, issues, and diagnostics, alongside a quick view of up to five "starred" accounts. Starred accounts can be flagged for priority access.

The overview also flags accounts showing significant changes in key metrics, including clicks and disapprovals, allowing teams to identify movement without opening each account individually.

For agency leadership, this page matters most. It answers the daily question: "Is anything on fire across our portfolio right now?"

Diagnostics

You can discover specific problems across all your client accounts with detailed data, filter data and issues by client, country, or marketing method, and prioritize fixes based on "click potential."

The click potential metric deserves special attention. The diagnostics page's click potential metric makes feed issues explicit: each unresolved issue carries an estimated traffic cost. Instead of treating all feed errors equally - which is what most agency teams do when they're triaging 20 accounts at once - this metric puts a dollar-adjacent value on every disapproval. A missing GTIN on a best-selling product with high search volume is not the same as a missing GTIN on a product that gets zero impressions. Click potential quantifies that difference.

Client Optimization

Client Optimization surfaces out-of-stock products across your entire portfolio with a "Share report" feature that lets you send restocking alerts directly to clients. It also tracks promotions by status - approved, under review, not approved - across all merchants.

You can also monitor store quality score and analyze areas needing improvement, as well as review key areas including shipping and return settings.

The promotion tracking is particularly useful during Q4 or any major sale event. When you're managing seasonal promotions for 15 clients simultaneously, knowing which promotions are stuck "under review" before Black Friday is the difference between revenue generated and revenue lost.

Ads Opportunities

Ads Opportunities identifies low-traffic products - items in the catalog getting zero or near-zero ad clicks. You can filter by criteria like "Low price" or "Trending brand," then apply custom labels directly from this view. Those labels flow into a supplemental data source in Merchant Center, which you can then use in Google Ads to target those specific products in campaigns.

This is the section that moves Merchant Center for Agencies beyond monitoring and into performance optimization. The labeling workflow bridges the gap between Merchant Center diagnostics and Google Ads campaign execution - a connection that previously required manual work across two separate platforms.

Here's how it works in practice: From the Ads Opportunities page, select "View" for the client row you want to edit. A "Low traffic products" page opens. Select "Label all" or select specific products and then "Label." Choose "Create a new supplemental source." A spreadsheet-based supplemental source will be automatically created and linked to your selected primary source.

This process applies the necessary custom labels to the targeted offers, which then appear in Merchant Center and Google Ads. You can filter for these targeted offers in Google Ads when setting up or modifying Shopping campaigns.

How to Set Up Merchant Center for Agencies: Step by Step

Setup is straightforward but not instant. There is a request-and-approval process that makes it essential to plan ahead. Step 1: Determine your eligibility. Merchant Center for Agencies is available exclusively to agencies that manage Google Merchant Center accounts for other businesses. Individual merchants or in-house ecommerce teams do not qualify.

Step 2: Submit your access request. Eligible agencies should submit an access request through Google's official support channel. Once approved, the agency dashboard becomes the default interface when logging into merchants.google.com.

If you are a new agency user, you need to complete the official Contact Us form on Google Merchant Center support to request an agency account.

Step 3: Access your agency dashboard. Existing users who already have an agency account go to merchants.google.com. Your agency account will be the default view.

Step 4: Link your client accounts. The tool requires accounts to be set up at the agency level rather than individual client level. The product is separate from the standard Merchant Center interface. Agencies that currently manage client accounts through individual logins will need to set up agency-level access to use the consolidated dashboard.

Step 5: Configure your starred accounts. Star your highest-priority clients to surface them in the Agency Overview page for quick daily access. Step 6: Set up user permissions. Assign team members to specific client accounts from the All Client Accounts page. This is where you build your team's daily operating rhythm - not in individual Merchant Center accounts. One critical note: Given that access requires a request and approval process, agencies should initiate setup well in advance of any upcoming retail peaks. Do not wait until September to request access if you want the platform operational for holiday season.

Practical Workflows That Change Once You're Set Up

Understanding the features is one thing. Knowing how they change your daily work is another.

Morning Portfolio Check (10 Minutes Instead of 60)

Before Merchant Center for Agencies, a morning feed audit across 20 clients meant opening each account individually, checking the "Needs Attention" tab, then context-switching to the next account. With the agency dashboard, you open the Agency Overview page once. Any account with suspensions, warnings, or significant metric changes surfaces immediately. The diagnostics page shows every issue across all 20 accounts, sorted by click potential.

The bottleneck in multi-account monitoring is usually finding the problem, not fixing it. That's exactly what this interface compresses.

Pre-Holiday Promotion Management

Socium Media used Merchant Center for Agencies to establish a central dashboard to monitor and validate promotions, inventory, and feed diagnostics for multiple clients in one interface for peak holidays.

Per Google, the agency achieved 50% faster resolution on tasks, and freed up time for additional client support.

When you're managing 12 clients running Black Friday promotions, knowing that three promotions are stuck "under review" across three different accounts - without logging into each one - is an operational advantage that directly protects client revenue.

Low-Traffic Product Recovery

The Ads Opportunities workflow is the most tactically valuable feature for PPC specialists. Many agencies discover that clients have entire product categories in their feed that generate zero Shopping impressions. Sometimes this is a bidding issue. Often, it's a feed issue - missing attributes, incorrect categories, or simply products that never got included in campaign targeting. By filtering low-traffic products by "Trending brand" or "Low price" and applying custom labels that flow into Google Ads, you create a bridge between feed data and campaign structure that previously required exporting spreadsheets, manually creating supplemental sources, and then building campaign segments in Google Ads.

The Bigger Platform Context: What Else Is Changing

Merchant Center for Agencies does not exist in isolation. Several parallel changes affect how agencies manage Shopping campaigns, and understanding them prevents blind spots.

The Content API for Shopping Sunset

In August 2025, Google officially announced the deprecation of the Content API for Shopping, setting August 18, 2026 as the final shutdown date. This change represents a fundamental shift in how merchants and advertisers manage product data within Google's advertising ecosystem.

Google is migrating from the Content API for Shopping to the new Merchant API, with both running in parallel until August 2026. If your agency relies on automated feed tools or third-party connectors, that migration affects you separately from Merchant Center for Agencies.

This is critical for agencies using custom feed management scripts or third-party tools that rely on the Content API. The migration involves more than a simple backend switch - feed labels do not automatically transfer, and failing to properly reconnect product feeds could cause campaigns to stop serving entirely. Confirm with every tool vendor in your stack that they've already migrated or have a clear plan.

Merchant Center Next as the Foundation

The Merchant Center Next rollout, completed in August 2024, set the technical foundation on which this agency layer is built. The transition replaced "Feeds" with "Data Sources," renamed "Diagnostics" to "Needs Attention," and consolidated analytics into a single Performance tab. Merchant Center for Agencies sits on top of that infrastructure.

If your team hasn't fully adapted to the Merchant Center Next terminology and navigation, doing so before requesting agency access will significantly reduce the onboarding learning curve.

The Competitive Angle

Amazon's advertising console already supports multi-account management for agencies, and Meta Business Suite has offered agency-level account management for years.

Google's addition of proactive diagnostics and merchandising tools that connect directly to Ads campaigns is designed to keep agencies operating within its commerce ecosystem as competition for retail ad budgets intensifies.

Google is filling a gap that competitors addressed earlier. For agencies juggling Amazon Ads, Meta, and Google Shopping, having equivalent multi-account tooling across all three platforms standardizes workflow in a way that reduces platform-switching overhead.

What Merchant Center for Agencies Does Not Do

Accuracy requires acknowledging limits. The main thing to keep in mind is that it's an operational tool, not a reporting one.

You won't find ROAS, CPA, or revenue-by-product data inside Merchant Center for Agencies. Merchant Center for Agencies gives you operational visibility. For campaign performance, ROAS, CPA, and revenue by product, you need Merchant Center data connected to Google Ads. Your reporting stack - whether it's Looker Studio, Google Sheets via connectors, or BigQuery - still handles the performance measurement layer. The platform also doesn't solve account ownership issues. If a client's Merchant Center account is set up as a sub-account under an agency's MCA and the agency relationship ends, disentangling that account remains painful. You cannot transfer sub-accounts under an MCA. This means once you create a sub-account, your client is locked in, which would cause issues when your client wants to move on. Best practice remains: let clients own their own Merchant Center accounts and grant your agency admin or standard access.

Google has not announced specific features planned for future updates to the platform.

However, the platform was developed through an iterative pilot process with agency feedback incorporated throughout, which suggests continued development based on user input.

--- Merchant Center for Agencies represents something agencies have asked Google for since the original MCC launched for ads accounts: the ability to treat product feed management with the same portfolio-level rigor that campaign management has received for over a decade. The broader rollout replaced complexities of the previous Multi-Client Account system with an interface that offers "MCC-like" oversight for product feeds.

Time spent on account monitoring and diagnostics is time not spent on strategy. Tools that compress that operational overhead - especially during high-stakes periods like Q4 - directly translate into capacity for higher-value client work. Agencies managing large retail portfolios should prioritize getting set up before the next peak season.

The path forward is clear. Request access now. Get your team onboarded during a low-pressure month. Build the diagnostics-first morning check into your daily operations. And use the Ads Opportunities labeling workflow to connect feed health directly to campaign performance - the exact connection that separates agencies running Shopping campaigns from agencies running them well.
