Challenge

Streamlining platforms to boost efficiency and performance

A leading US mattress retailer was managing campaigns across five DSPs—including Criteo and several top industry players. With limited internal resources and growing pressure to streamline operations, they launched an audit to simplify their tech stack and reduce platform fragmentation.

The retailer’s goal was to consolidate partners—choosing one for lower funnel performance, and another for upper funnel reach.

As part of this evaluation, they narrowed the field and ran a three-way lower funnel head-to-head test, including Criteo. The DSP partner with the strongest attributed omnichannel ROAS results would win the business.

Solution

Optimizing structure, strategy, and scale

In collaboration with the client, the Criteo team—including Account Strategy, Analytics, Design, and Engineering—rolled out a series of focused optimizations to align with the retailer’s goals:

  • The creative strategy was refreshed with expanded ad sizes and dynamic creative optimization features to enable further personalization.
  • Criteo AI bidding was tailored to optimize toward the client’s source of truth reporting.
  • Audience and device targeting was revised to expand unique reach and improve CPM efficiency.
  • The catalog strategy was optimized to reflect real-time shopper intent and increase ad relevance.
  • A new frequency cap was implemented to limit user saturation and further maximize audience exposure.
Results

Delivering best-in-test performance and earning full budget consolidation

By the end of the competitive test, Criteo’s Commerce Growth more than doubled ROAS from 4x to 8x. Compared to the other two DSPs, Criteo outperformed by 30% and 50%.

As a result, the retailer moved their entire lower funnel budgets to Criteo and is now planning a test with Criteo’s mid and upper funnel solutions as the next phase of growth.

“We love working with Criteo, so we were honestly relieved to see the performance speak for itself here.”
