01. Create your GMCMax account
Use your name, email, and a strong password to create a private workspace. Review the Terms of Service and Privacy Policy before continuing. Account creation does not collect payment information or activate any automation.
02. Connect your Shopify store
The setup guide helps you create a merchant-owned Shopify app, install it, set the required API scopes, and securely enter the app credentials. You only type your store subdomain; GMCMax adds .myshopify.com.
03. Select your Google Ads account
Authorize through Google, then verify the advertiser customer ID you want to report on. If you access that advertiser through a manager account, enter the optional manager ID too.
04. Sync and review your products
After syncing, open the dashboard and compare the same reporting dates. Product-protection automation is optional and off by default. If you want automatic Google & YouTube unpublishing, choose a spend-to-retail-price percentage and explicitly activate it in Automations.
Build a repeatable review
Start with spend reconciliation, then sort products by spend or ROAS. Expand variants, compare dates, and check Google & YouTube publishing. Numbers update when synchronization finishes, subject to delays at Shopify and Google.
