Aroma marketing: it is to use the fragrance of the same space to combine with other design elements to create or improve the environment. The use of fragrance marketing is a long-term systematic plan. Through this use, scent as an olfactory element acts in this application similarly to visual elements such as: graphics, colours, materials, textures and shapes as well as auditory elements such as music。

Use the environment to create fragrance, use carefully selected fragrances to improve the marketing theme, animation visual effects, and make the tree or flower shape smell closer to the natural taste. The main purpose is to associate the scent experience with the brand, using scent to amplify and promote the brand, just like hotel chains use diffusers to make all hotel lobbies have the same scent. By creating a pleasant fragrance, indoor air quality and overall ambience are greatly enhanced and improved. 

Scents can remind people of a brand with positive emotions and communicate the brand‘s values. Fragrance can also create an inviting environment, attracting retail customers and making them stay longer and buy more items; it can also improve employee productivity power and make it a positive experience for all occupants of the space. 

Of all the human senses, smell is a very powerful memory trigger. Seek to provide a positive fragrance scent experience that customers will linger on and reminisce about the hotels, casinos, retail stores and other venues they have visited. Enterprises not only use fragrance to improve indoor air quality, but also use fragrance to enhance the emotion and connection between guests and the company‘s brand.
