Visual Marketing v/s Plain Text Marketing

Visual marketing is the discipline studying the relationship between an object, the context it is placed in and its relevant image. Representing a disciplinary link between economyvisual perception laws and cognitive psychology,[1] the subject mainly applies to businesses such as fashion and design.
As a key component of modern marketing, visual marketing focuses on the studying and analysing how images can be used to make objects the centre of visual communication. The product and its visual communication become therefore inseparable and their fusion is what reaches out to people, engages them and defines their choices (a marketing mechanism is known aspersuasion[2]). Not to be confused with visual merchandising, that is one of its facets and more about retail spaces; here, Marketing gets customers in the door. Once inside, merchandising takes over—affecting placement of products, signage, display materials, ambiance and employee staffing.
Harnessing the power of images and visuals makes a marketing plan more powerful and more memorable. Images — when done deftly – can turn concepts and intangible things into something concrete. That helps people envision a brand and its message in their mind’s eye — and remember it when it comes time to buy.[3]
Visual Marketing can be a part of every aspect of the Communication Mix. Marketing persuades consumer's buying behaviour and Visual Marketing enhances that by factors of recall, memory and identity.
Growing Trends in the usage of Picture Based Websites and social networking platforms like PinterestInstagramTumblr, Timeline feature of Facebook justifies the fact that people want to believe what they see, and therefore, need for Visual Marketing.
