Google Merchant Center Integration

Google Merchant Center integration

This integration works differently — it's not about pulling data into Shopimize, but about pushing profitability labels out to Google to improve your ad bidding.

What this does

Shopimize creates custom product labels based on your profitability data and pushes them to Google Merchant Center as custom_label_0 through custom_label_4. In Google Ads, you use these labels to split Shopping campaigns or PMax asset groups by profitability — bidding more on high-margin products and pulling back on low-margin ones.

Setting it up

Step 1: Create label rules in Settings → Product Labels. Define what "High Margin", "Top Seller", "Underperforming" means for your store.

Step 2: On the same page, click Connect Merchant Center and sign in with a Google account that has access to your Merchant Center account.

Step 3: Click Evaluate, then Push to Merchant Center.

What you'll see in Merchant Center

Shopimize doesn't edit your product feed. The first push adds a supplemental data source named Shopimize profit labels, listed on the Data sources page of Merchant Center, and links it to your product sources. Labels are applied from it within a few minutes.

If your feed already fills a custom label slot, your feed's value is kept and Shopimize's label for that slot isn't applied. Use slots your feed leaves empty.

Later pushes only send labels that changed. With a large catalog, a push can stop before the end to stay within the time limit; the result message says so, and pushing again finishes it.

In Google Ads

Push to Google Ads splits your product groups by a label for you. If you have more than one rule, choose the label first. Shopimize shows what will change and asks before changing anything. It:

• splits Shopping ad groups and Performance Max asset groups that still use a single "All products" group, and keeps groups already split by that label up to date;
• copies each group's current bid and exclusion to the new product groups, so nothing you advertise or bid changes until you adjust it per label;
• leaves groups you've split another way (brand, category, item ID…) exactly as they are.

Push to Merchant Center first: product groups match products by the label Merchant Center holds.

To do it by hand instead, open your Shopping campaign → Product groups → subdivide by Custom label, then set bids or ROAS targets per label.

Keeping labels current

Labels don't update automatically — push them manually when you want to refresh. Once a month, or after significant cost changes, is a good cadence.
