Fenster.com is the No. 1 online shop for windows and doors in Germany. Behind the online store is Neuffer Fenster + Türen GmbH, based in the Swabian capital of Stuttgart. Founded on January 13, 1872, the company can look back on over 150 years of experience in door and window construction in the private and commercial sectors. In addition to fenster.com, we also manage the online stores for the Austrian (fensterversand.at) and French (fenetre24) markets.

Our challenge was to effectively advertise a wide range of products for Fenster.com while maximizing relevance through dynamic ad delivery to achieve significantly higher conversions and increased customer loyalty.

Our strategy includes the dynamic display of ads through a third-party tool to present personalized content based on user behavior and interests. At the same time, we use static ads via the product catalog to show a consistent and broad offering. By combining both approaches, we maximize the relevance and appeal of our advertising measures, which leads to higher conversion rates and stronger customer loyalty.

Market-specific adjustments were also made to tailor the campaigns to the needs and preferences of the various target markets, including Germany (DE), Austria (Ö) and France (FR).
