Warning messages on product packaging play an important role in enhancing consumer safety. Previous studies have demonstrated a significant effect of pictorial safety messages on people’s visual attention, highlighting the importance of picture-based design in the context of warning communication through packaging. However, limited attention has been given to packaging displayed in the advertisement, which this study aims to address. In our experiment, an eye-tracking device was used to examine the effects of the safety pictogram on participants’ visual perception of an advertisement displaying a packaging for nutritional supplements. A comparison was conducted between two packaging designs (a packaging without the pictogram versus packaging with the pictogram). Eye tracking data (Time to First Fixation, Fixations Before, Total Fixation Duration, Fixation Count, Total Visit Duration) were recorded for each segment of the advertisement (Areas of Interest), and scan paths of each participant were analysed. The results showed that the participants allocated visual attention to the safety pictogram, but their focus on the pictogram did not affect the noticeability of the advertised tagline and the brand name. These findings indicate that improving warning communication on packaging by pictorial safety message does not compromise the noticeability of the elements most important to advertiser.
