Performance Marketing Team



The challenge

iCarros had already worked with one retargeting partner to maximize the performance of its online marketing activities. However, they knew that they had more opportunities within the retargeting environment. This led to the decision to team up with RTB House for multiple retargeting strategies that could help achieve strategic goals set for the performance team:

  • Bring more conversions with the ideal CPL (Cost Per Lead)
  • Deliver stable CPL throughout the month
  • Grow the campaign in a sustainable way

iCarros was also looking for a retargeting provider that pays great attention to the customer service, transparency and has a proactive approach.


The solution

RTB House based on its expertise within the classifieds vertical, a flexible approach and understating of the client’s goals created a Deep Learning-powered retargeting campaign. It focused on users who are most likely to convert.

The campaign was optimized along the way to maximize its potential, increase volumes and deliver more conversions at a stable cost.


The result

The implementation of a multiple retargeting strategy generated greater profits and drove better results for iCarros.

  • In just 3 months, RTB House became the first choice retargeter for iCarros, thanks to great results and helpful customer service.
  • RTB House now represents 72% of conversions coming from retargeting channels.
  • RTB House technology allowed iCarros to maintain stable CPL and increase each campaign’s volume month by month.
