How Online Shops Use the New Aggregator Units to Boost Their Reach
The Digital Markets Act (DMA) is fundamentally changing Google Search in the European Economic Area (EEA). With the new CSS aggregator units, Google now strictly separates results into two areas: on one side pure comparison shopping services (CSS), on the other direct merchant offers.

Many e-commerce operators are unsettled: direct product ads slip into the separate merchant section, while generic searches (“men's running shoes”, “bean-to-cup coffee machine”) are increasingly dominated by the prominent aggregator boxes. If you rely solely on the standard Google Merchant Center, you risk handing valuable visibility and traffic over to third-party portals.
Google Shopping strategies for more revenue, in your inbox
Every other week: what is changing in Google Shopping, what we see in our customers' accounts, and what to do about it.
From Traffic Loss to Double Presence
Changes in the Google ecosystem are not a risk but a battle over distribution. Instead of seeing comparison shopping services as pure competition, forward-thinking merchants use them as strategic traffic distributors. This is exactly where csspartner.io comes in, turning the new market rules into your competitive advantage:
- Maximum coverage through Multi-CSS: With csspartner.io you stay present in the classic merchant area and at the same time secure placements in the newly highlighted aggregator units.
- 20 % lower click costs or 25 % more bidding power: When you advertise through a CSS, Google's 20 % margin on the cost per click (CPC) no longer applies. You pay 20 % less for the same click or bid 25 % more with the same budget – that means more reach at the same cost.
- Automated feed monitoring: Product data checked daily prevents missing approvals in Merchant Center and keeps your items eligible to serve in all formats.
- Optional click fraud protection: Available as a bookable add-on, it filters out bots and invalid clicks before they drain your ad budget.
- Zero downtime when switching: Your campaigns, history and bids keep running without interruption. The connection is made simply via an invitation in Merchant Center.
Reclaiming the Customer Journey
The clear separation between merchants and aggregators calls for flexible ad sets. If you switch to a hybrid CSS strategy early, you secure the top spots in the buyer's decision process – long before the competition catches up.
