Abstract: - This thesis dives into the significance of social media marketing within a business. It starts off with a literature review that describes how much people use social media, how businesses have begun to acknowledge this trend, and how to whirl this trend into a successful marketing plan.This strategy can be demonstrated through online advertisements, influencer marketing, and a strong social media presence. This theory will identify and examine all of these techniques. The second part of this theory is based on an online survey provided to the general public in order to discover if the findings in the literature review are correct. The survey shows that people use on average 2 and a half hours on social media a day. And, they visit multiple different social media platforms everyday.One of the most revealing findings in this study was that people are being influenced more by the things they view on social Media, as they trust those opinions, than other forms of marketing. Social media marketing has replaced the significance of commercials, billboards, and print ads.
