Reasoning
Companies very carefully choose people to use to advertise their products on social media. If a company chooses an influential person, this saves the company tons of time and money. The company really does not have to do much aside from sending the person of their choosing a few products. They involve things like promotion codes or free small gifts to attract customers to their social media advertisements. The people that they choose to use are usually very influential and have a large following on social media. They are usually well-liked by many groups of different people because that way they can reach more people. The audience also plays a large part in how companies market on social media. Since the majority of social media users are pretty young, companies target their advertisements towards the younger generations.
