Understanding the cognitive processes of consumers, such as attention or perception, can help orient marketing activities in such a way that the information provided to recipients is delivered in the most effective way possible. Neuromarketing methods-in contrast to conventional methods-enable scientists to measure the subconscious reactions in response to stimuli, thereby giving insight into decision-making processes, consumer preferences or motivations. One of the most commonly used methods of this type is eye-tracking. In recent years, there has been a noticeable increase in the popularity of using this technique as it provides valuable information regarding the visual processing of stimuli. The purpose of this publication is to present the possibilities of using eye-tracking in marketing research, including identifying the main research areas and insights from previous research. In the beginning, necessary information about the method will be presented, providing context for further considerations, such as eye movement characteristics and fundamental measurement indicators. Then a review of the studies conducted using eye-tracking will be carried out. A broad spectrum of the use of eye-tracking provides the opportunity for future studies to combine this method with other neuromarketing techniques (including the electroencephalography or magnetic resonance imaging).
