Google PartnerPremier 2026A catalog is managed to margin.
The ROAS reported by Google compares revenue with spend. It says nothing about each product's margin. A category with a very strong ROAS can sell at a loss, and vice versa. Here are both views, side by side.
By ROAS, electronics and shoes come out on top and get the budget. By margin, electronics and apparel sell at a loss once advertising is paid for: the budget shifts to accessories and shoes.
Fictional categories and values. The actual ranking starts from your margins by product and your recorded sales.
One feed, several storefronts.
The same product feed powers several placements across Google. Its quality determines the delivery of every campaign that uses it.
Merchant Center
The platform where your catalog is sent to Google: titles, prices, availability, images, product identifiers. Disapproved products do not appear in any campaign.
Standard Shopping
Ads with image, price and merchant name in search results and the Shopping tab, with bids set by product group.
Performance Max
The feed served across all of Google's inventory, with your creative assets, toward a conversion goal.
Free listings
Products in the feed can also appear at no cost in Google's Shopping tab, in addition to ads.
How we launch your catalog.
The feed first, then measurement, then campaigns. Each step builds on your sales setup, whatever the platform.
Feed
Fixing disapproved products, completing titles and attributes, aligning categories with how your customers search.
Measurement
Sales values and conversions checked between your store and Google Ads.
Structure
Campaigns organized by category and by margin level, across Standard Shopping and Performance Max.
Management
Tracking sales and profitability by product, and shifting budget toward what truly pays off.
A team dedicated to the success of your campaigns.
JAAB works with more than fifty international clients, with a 97% recommendation rate. The agency was founded in 2023 by two former Google and Twitter employees, and now has seven people.
Google has awarded it Google Partner Premier status, the highest tier of its partner program, reserved each year for the top-ranked agencies in each country.
We prefer to manage a catalog to margin rather than to the ROAS reported by the platform, and our fees remain separate from the media budget.
Google Shopping, in practice.
01What does a Google Shopping agency do?
It optimizes the product feed sent to Google, builds and manages Shopping and Performance Max campaigns, and measures the sales they generate. JAAB also develops tactics by industry and by product category to increase your sales and profitability.
02What is Google Merchant Center?
It is the Google tool that receives your catalog: titles, descriptions, prices, availability, images and product identifiers. Shopping and Performance Max campaigns rely on this feed, and a product disapproved in Merchant Center cannot be served.
03Standard Shopping or Performance Max: which should you choose?
The choice is based on the margin each one actually generates, not on reported ROAS. Both use the same feed. Standard Shopping lets you set bids by product group and see the queries. Performance Max extends delivery to all of Google's inventory, with less visibility into placements.
04Do you work with Shopify and WooCommerce?
Yes. JAAB supports its clients on their own setup, including Shopify and WooCommerce, and offers its measurement tools for the most accurate view of performance.
05Why manage to margin rather than to ROAS?
Because two products with the same ROAS do not earn the same amount if their margins differ. Managing to margin lets you push the products that make a profit after advertising costs and limit those that sell at a loss.
06What budget should you plan for Google Shopping?
The media budget follows from demand for your products and the cost per sale your margin allows. JAAB's fees are separate from the media budget.
07Who owns the accounts?
Your Google Ads accounts remain your company's. JAAB accesses them from its manager account, with permissions you can revoke at any time.
