The iPhone was one of the biggest products I can think of that had the most influential buying factors in its favor. All of the factors that affect consumer decision making, cultural factors, exert the broadest and deepest influence. If all of my friends have something that makes me want it even more. This is a very important thing for marketers to understand is that if its in people culture and society and its accompanying values, as well as their subculture and social class, all influences their buying behavior.
If a company understands this it gives them an advantage to how they can get products to appeal to consumers and for it to be the "must-have" product.
Other organizations that can take advantage of the influential factors is clothing stores, electronics, music, and restaurants. If all these things are well known in societies, people have more knowledge about the product or service, which creates a bigger target market.
What are the biggest influences on consumer buying decisions in your opinion?
