You can also create your own products with digital and physical. Though I would recommend to begin with Digital products (like eBooks, courses etc.) because they are easier to create and promote and take less amount of money in the beginning to develop the products. For instance, you can list your eBook on Amazon Kindle or ClickBank and then promote the link of your eBook on different social media channels. And once the sales start rolling, you have to do nothing but collect the payment (being a digital product, you can sell it N number of times!).
Social media is a computer-based technology that facilitates the sharing of ideas and information and the building of virtual networks and communities. By design, social media is internet based and offers users easy electronic communication of personal information and other content, such as videos and photos. Users engage with social media via computer, tablet or smartphone via web-based software or web application, often utilizing it for messaging.

Founded more than a decade ago (November 2004), Digg is a news aggregator with a curated front page that selects stories specifically for the Internet audience, The topics vary widely from trending political issues to science to viral Internet issues and anything in between. Digg supports sharing of content to other social media platforms such as Facebook and Twitter. In 2015, the company claimed that it had about 11 million active monthly users.
As one of the biggest preoccupations among adolescents is social media usage, researchers have begun using the term "F.A.D.," or "Facebook addiction disorder," a form of internet addiction disorder.[192] FAD is characterized by a compulsive use of the social networking site Facebook, which generally results in physical or psychological complications. The disorder, although not classified in the latest Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or by the World Health Organization, has been the subject of several studies focusing on the negative effects on the psyche. One German study, published in 2017, investigated a correlation between extensive use of the social networking site and narcissism; the results were published in the journal PLoS One. According to the findings: "FAD was significantly positively related to the personality trait narcissism and to negative mental health variables (depression, anxiety, and stress symptoms)."[193]
The other big mistake retailers make is to use social media to talk about what is important to them rather than talking about what is important to the customer. As a retailer, you may think it is great to shout that you have a sale going on; and in some regards, this would be true. But, if that's the only reason you are getting involved in social media it won't be beneficial. Your goal should be to provide content that is relevant to your customer and engage with them to the point that they want to share your post with others.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly.[7] Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying.[8] Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.[9]
