Shopify+Google Ads
A clear view. An honest one.
Ad-attributed conversions and total Shopify sales are different measurements. We keep the distinction visible. A missing match stays unmatched. A delayed number is not described as real-time.

Permission, not assumption
Your accounts stay yours.
Understand the access before you connect.
Google Ads
Google’s authorization flow connects your account without sharing your Google password. Reporting reads spend and performance. Product removal is requested through the Shopify feed, not an instant campaign pause.
Shopify
You own the custom app. Setup shows the requested read and write scopes. Google & YouTube publishing is controlled through product switches and optional Automations.
Your data
Integration credentials are encrypted before database storage. Your workspace keeps your records separate from other merchants.
Your control
Disconnect either source to remove its stored credentials. Workspace owners can delete their workspace and active data from Account settings.
What does GMCMax show me?
Connect Shopify and Google Ads to compare product-level ad spend, Shopify sales, refunds, units sold, and ROAS. Expand variants, choose dates, and see the portion of campaign spend that cannot be matched to a product.
Is product ROAS the same as Google Ads ROAS?
No. Product ROAS divides net Shopify sales by matched Shopping spend. Shopify sales include all channels. Google Ads conversion metrics follow Google’s attribution rules. GMCMax labels these separately so you can compare like with like.
Does GMCMax change my products or campaigns?
Automatic Google & YouTube unpublishing is optional and off by default. If you activate it in Automations, it unpublishes qualifying products from that channel after sync. Shopify product status and all other channels stay unchanged. You can adjust the percentage or deactivate it at any time. It does not directly pause campaigns or change bids or budgets; feed changes are not instant.
How does the Shopify connection work?
You create a merchant-owned custom app in Shopify, install it on your store, and enter its credentials in GMCMax. The guided setup supplies the app URL and exact permission list. Your Shopify password is never requested.
How current are the numbers?
You can select Today, a preset, or a custom date range and refresh supported dates. Freshness depends on the last successful sync and the source platforms’ reporting delays. Today is a partial day, and conversions can be revised later.
Can I compare countries and date ranges?
Yes. Compare date ranges and filter Google Shopping spend by country. Country-level Shopify revenue is not currently attributed, so GMCMax does not invent country-specific Shopify ROAS.
What happens when I disconnect?
GMCMax removes stored integration credentials and stops future collection for that source. Historical reports can remain in your workspace. Workspace owners can delete the workspace and its active data from Settings.
Does GMCMax include Meta advertising?
No. GMCMax currently focuses on Shopify and Google Ads. There is no Meta account connection or Meta ad spend in the dashboard.
