Criteo’s Approach:
Criteo places itself at the center of the ecosystem, hence has the most power of all the stakeholders involved. The working model is such that advertisers use Criteo’s dashboard to place ads on retailers’ platforms and retailers have to adhere to ad format and dimension norms set by Criteo.
Retailers have limited control over the ad inventory and almost no means to build a relationship with advertisers- Criteo’s business model is designed to ensure this.
