Introduced herein are techniques for bringing scented advertisements into digital content (e.g., visual content and non-visual content). Such technology is able to address a fundamental challenge that is inherent in digital transactions, namely, an inability to accurately gauge different characteristics of a product. Several embodiments pertain to scent delivery systems that are able to produce scent(s) as part of a direct advertising campaign or an indirect advertising campaign. More specifically, a scent delivery system may be configured to produce scents that correspond to features of the digital content. For example, different scented materials can be dispensed based on characteristics of a product that is the subject of a scented advertisement.
