Digital marketing is an intelligent use of social media. These give pride of place to consumers who share their experiences. This engenders interaction with companies that can benefit by building strong relationships with their audiences.
If you read on Facebook that a friend liked, or not, a product he just bought, do you trust him? Personally, this opinion is essential for me. Many studies show that this is the case for the majority of people.
Social marketing relies heavily on these signals. They serve as real evidence and customer testimonials support the argument of companies that are now easily questioned. The stronger a social signal, the more confidence it creates.
