Positioning is a marketing strategy that aims to make a brand occupy a distinct position, relative to competing brands, in the mind of the customer. Companies apply this strategy either by emphasizing the distinguishing features of their brand (what it is, what it does and how, etc.) or they may try to create a suitable image (inexpensive or premium, utilitarian or luxurious, entry-level or high-end, etc.) through advertising. Once a brand is positioned, it is very difficult to reposition it without destroying its credibility. It is also called product positioning.
