Merchant Center for Agencies now links up to 1,000 client accounts under a single agency login. Google recently documented that limit for the first time. If your agency runs Google Shopping feeds for dozens or hundreds of retailers, that number sets the ceiling for how far one account scales. The platform gives you a central hub to manage every client’s product data, diagnostics, and user access in one place. This guide explains what Merchant Center for Agencies does, what the new 1,000 account limit means, the roles and dashboards inside it, and how to structure your agency account so it grows without breaking.
Key takeaways
- Merchant Center for Agencies links up to 1,000 client Merchant Center accounts under one agency account.
- Google released the platform globally in May 2026 after testing in the US and Canada.
- A central hub shows every client’s status, diagnostics, and optimization opportunities in one view.
- Two roles, Admin and standard user, control access, and labels scope which clients each person sees.
- Only agencies that manage Merchant Center accounts for other businesses qualify to use it.
What is Merchant Center for Agencies?
Merchant Center for Agencies is Google’s control panel for shops you do not own. It lets an agency manage many client Merchant Center accounts from one login instead of juggling separate credentials for each retailer. Google built it for agencies that run Shopping and product feeds on behalf of other businesses, so a solo merchant managing a single store does not need it.
The agency account acts as a hub. So from there you organize client accounts, star the ones you touch daily, hide inactive accounts from the main list, and finally see who holds access to what. It is the layer above the individual Merchant Center, much like the account structures agencies build to run AI Max for Shopping campaigns at scale.
What does the 1,000 linked account limit mean?
Until recently, Google never published a hard cap, which left agencies guessing how far the platform would stretch. However, the updated documentation settles it: one agency account can link up to 1,000 client Merchant Center accounts. As a result, that clarity matters for planning. You now know when a single agency account will run out of room, so you can design onboarding and account structure around a real number rather than a rumor.
For most agencies, 1,000 is plenty of headroom. Still, very large portfolios that pass it will need more than one agency account, so it pays to plan the split early. For example, group clients by brand, region, or team from the start, and you avoid a painful reshuffle later.
What can you do from the agency hub?
Still, the platform is more than a login shortcut. In addition, it surfaces problems and opportunities across your whole book of business through a set of purpose-built pages.
- Agency Overview: a portfolio snapshot with account status, issue tracking, and metrics on your top starred accounts.
- Diagnostics: problem identification across clients, filterable by client, country, or marketing method, with click potential estimates to help you triage.
- Client Optimization: promotion management, out-of-stock monitoring, store quality scores, and shipping or return checks.
- Ads Opportunities: low-traffic product spotting and aggregated stats across merchants, with labels that feed campaign work.
Those diagnostics matter because feed and inventory issues quietly drain performance, the same way dead SKUs sit unsold inside Performance Max until something surfaces them.
User roles and account access
Merchant Center for Agencies uses two roles. Therefore, get them right and access stays clean as your team grows.
- Admin: full control. Admins create and manage roles, link and unlink client accounts, reach every linked client by default, and set what standard users can touch.
- Standard user: scoped access. Admins grant these users specific clients, often through labels, so a strategist sees only the accounts they run.
Also, labels do the heavy lifting here. First you tag client accounts, then you grant a user access to a label instead of naming accounts one by one. That keeps permissions tidy across a large roster and speeds up onboarding when a new hire joins a pod.
How do you link a client account?
Google supports three linking methods, and the direct path is the common one. First, an Admin opens the All client accounts page, chooses Add an account, enters the client’s Merchant Center ID, and confirms. Then the same steps link a client’s existing multi-client account. Because the process needs the client’s Merchant Center ID, build a simple intake step that collects it during onboarding so linking never stalls.
How should agencies structure Merchant Center for Agencies?
So treat the account like infrastructure, not a quick setup. In short, a few habits keep it healthy as you scale:
- Design a labeling scheme before you add clients, so tags stay consistent.
- Reserve Admin rights for a small group, and give everyone else scoped standard access.
- Star active accounts so the overview shows the work that matters today.
- Review the Diagnostics page on a schedule, not just when a client complains.
- Plan for the 1,000 account ceiling if you run a large or fast-growing portfolio.
Strong internal structure is part of running a profitable agency, a theme we cover in our agency growth guide for niche industries. It also feeds the wider shift toward Google’s universal commerce protocol and its SEO implications, where clean product data increasingly drives visibility.
