One store per workspace
Create unlimited free workspaces under one GMCMax account. Each workspace has one Shopify store and one Google Ads advertiser, with separate connections, reports, saved views, and optional automations. There is no combined multi-store rollup.
Use the same review framework
Apply consistent date ranges, revenue definitions, and spend-reconciliation checks to each business you manage. Keep currencies and account timezones explicit when comparing results outside the app.
Discuss your setup before connecting
Use the workspace menu to create or switch workspaces. Name each workspace in Settings so the right store is easy to find. Each new workspace starts empty, with feed automation turned off.
