Ginny, your Google Ads agent, builds campaigns for your high-margin products only. The free plugin sends your purchase prices to Cloudginny, which turns them into margin classes for Google Shopping. Nothing goes live until you approve it.

Your margin classes can be selected in Google Ads. Here’s how I’d set up the campaign:
Shall I create it like this? Just answer Yes or No.
Done.
Campaign liveGinny can make mistakes. Nothing is carried out until you approve.
On its own, Google Ads only knows your selling prices, not how much you keep. So a product with a 50% margin competes for the same budget as one with 10%. Some products lose you money with every click, and you don’t notice until the end of the month.
Example, all prices net.
Run your high-margin products in their own campaign, with their own budget.
Products with a negative margin and products without a purchase price each get their own group. Filter by it in Merchant Center, and Ginny shows you what those products cost you in Google Ads.
Ginny breaks down cost, conversion value and ROAS by class.
When prices or purchase prices change, we recalculate that night. A product only switches class once its margin moves at least 2 points past the boundary. Time-limited sale prices don’t change it. That keeps your campaigns steady.
Install the free plugin from the JTL Extension Store and enter your Cloudginny key. From then on, it sends your products automatically. You’ll find the key in Cloudginny under Settings → API & Integrations once you’ve signed up.
A workflow in JTL-Wawi writes your purchase prices into function attributes. You only set it up once.
We calculate the margin of every product we can find in your Merchant Center and write its class into an unused custom label. Your feed file stays exactly as it is. With two JTL shops in testing, we matched 96% and 98.5% of the products in their Merchant Center to an item in the shop.
Tell Ginny which margin classes you want to advertise, as a Shopping or Performance Max campaign. She shows you the campaign first. It only goes live once you approve it.
Margin = (selling price − purchase price) ÷ selling price, both net
Fewer than 500 products found: three classes
500 products or more: five classes
Ginny first checks whether your margin classes can already be selected in Google Ads. Then she shows you the campaign, and you say “Yes, please.” Only then does it go live.
The only thing we write to your Merchant Center is each product’s margin class, for example cg_high_margin (40% margin or more). Google never sees your purchase price. Don’t want to share a product’s purchase price? Just leave the field empty. The product then goes into the “no purchase price” group.
