DeinDeal doubles ROAS and hits record revenue with GO campaigns

4x Increase in revenue
Nearly 2x ROAS from 14x to 24x
+100% Investment with higher profitability

Challenge

Overcoming limits to profitable scale

DeinDeal is a leading Swiss online marketplace and the top supplier of flash sales, offering heavily discounted products across fashion, electronics, travel, and lifestyle.

For years, Criteo had been one of DeinDeal’s strongest performance channels, delivering consistent scale and strong ROAS. However, scaling profitably became more difficult as they approached the limits of their existing setup. This changed when they launched GO campaigns.

After receiving an email from Criteo introducing GO, the DeinDeal team decided to test it with a small daily budget. Performance quickly exceeded expectations, revealing a clear opportunity to unlock new scale.

Solution

Activating GO to simplify and scale performance

In April 2025, DeinDeal activated its first GO Campaign with the objective of maximizing conversions.

What started as a small experiment quickly became the marketplace’s default Criteo setup. As performance continued to improve, DeinDeal expanded its use of GO to support key initiatives such as Black Week promotions and scaling activity across social inventory. Today, about 90% of their total Criteo spend runs through GO campaigns.

GO not only matched but surpassed the results of other retargeting platforms. As a result, the DeinDeal team moved budgets back to Criteo and established GO campaigns as a core component of their marketing mix. GO campaigns fit seamlessly into their broader automation strategy across all channels.

Results

Achieving record revenue and doubled ROAS

Since adopting GO, DeinDeal has significantly scaled its Criteo investment while improving efficiency. Year over year, the company increased its Criteo investment fourfold while maintaining strong profitability, with ROAS nearly doubling from 14x to 24x.

Even in January, typically one of the slowest months of the year, performance remained strong, with ROAS increasing by 113% YoY. The impact translated into the highest year-over-year revenue growth DeinDeal has seen from Criteo.

The team has since been recommending the GO approach to peers, highlighting its simplicity, strong automation, and significant performance impact.
