The challenge

Previously recorded results had deteriorated, Castex’s Branding campaigns tended to vampirize the campaigns carried out and off-brand KPIs were below targets.

The family business therefore decided to look for a new service provider able to provide a solution to the problem identified.

The solution

With the SteerFox platform, Castex was able to reorganize itself on a category and product-oriented logic, by integrating KPIs defined with SteerFox.  The campaigns are automatically updated on a daily basis according to price variations, stock changes or promotions. SteerFox brings its know-how and automation technology to improve the semantics and management of the campaigns. The campaigns can be consulted in real time on the SteerFox dashboard.

SteerFox’s automated approach combining Artificial Intelligence, algorithms, learning curve and human actions with the support of our account manager, convinced us to approach another way of doing SEA and Google Shopping + CSS campaigns. The relationship with SteerFox is fluid and professional. The monthly reports are the subject of exchanges and joint decision-making. If necessary, intermediate calls or exchanges by messaging demonstrate a real commitment and an appreciable availability.
