About Carglass
Carglass® is widely known through its commercials - “Carglass® repairs, Carglass® replaces”. Because of this reputation, Carglass® is often the first port of call when you have glass damage to your car.
Initial situation
In addition to replacing and repairing glass damage to the vehicle, Carglass® also offers other additional products, such as windshield sealing. This can be added online as an additional product in the final step of the appointment booking process. During the appointment, the windshield sealant is applied to the windshield after the damage has been repaired.
Through continuous optimization via A/B tests, the acceptance rate of windshield rain repels will sustainably be increased. At the request of Carglass, the acceptance rate cannot be disclosed.
Variants
Hypothesis
If the visitor is shown a night scene with a deer instead of the highway image,
Then the acceptance rate for windshield rain repel increases,

Conclusion
This uplift was not only confirmed in the experiments, but also in the absolute order intake in the months that followed. In absolute figures, the rate of new bookings increased from February 2022 to February 2023 by 182 % be increased.
