Definition of Product Attributes
A?product attribute?is a characteristic that defines a particular product and will affect a consumer's purchase decision. Product attributes can be tangible (or physical in nature) or intangible (or not physical in nature).

Tangible Attributes
Tangible attributes can include such product characteristics as size, color, weight, volume, smell, taste, touch, quantity, or material composition.
For example, when you want to buy a new car, you might consider tangible attributes such as its size, color, and material composition. If you are looking for a 2-door, red sports car with a leather interior, you are searching for a product based on its tangible attributes.
?
Intangible Attributes
Intangible attributes may include such characteristics as price, quality, reliability, beauty or aesthetics, and je ne sais quoi (an indefinable, elusive pleasing quality).
Again, if you are looking to buy a new car, you might also consider intangible attributes such as price, quality, and safety test scores. If you want a new car that is relatively inexpensive but has garnered high marks on performance tests, you are searching for a product based on its intangible attributes.
