Before social media, admissions officials in the United States used SAT and other standardized test scores, extra-curricular activities, letters of recommendation, and high school report cards to determine whether to accept or deny an applicant. In the 2010s, while colleges and universities still use these traditional methods to evaluate applicants, these institutions are increasingly accessing applicants' social media profiles to learn about their character and activities. According to Kaplan, Inc, a corporation that provides higher education preparation, in 2012 27% of admissions officers used Google to learn more about an applicant, with 26% checking Facebook. Students whose social media pages include offensive jokes or photos, racist or homophobic comments, photos depicting the applicant engaging in illegal drug use or drunkenness, and so on, may be screened out from admission processes.
One of the key components of SMM is social media optimization (SMO). Like search engine optimization (SEO), SMO is a strategy for drawing new and unique visitors to a website. SMO can be done two ways: by adding social media links to content such as RSS feeds and sharing buttons, or by promoting activity through social media via status updates, tweets, or blog posts.
Social media personalities have been employed by marketers to promote products online. Research shows that digital endorsements seem to be successfully targeting social media users, especially younger consumers who have grown up in the digital age. Celebrities with large social media followings, such as Kylie Jenner, regularly endorse products to their followers on their social media pages. In 2013, the United Kingdom Advertising Standards Authority (ASA) began to advise celebrities and sports stars to make it clear if they had been paid to tweet about a product or service by using the hashtag #spon or #ad within tweets containing endorsements.
Keep in mind that neither your customers' experience nor your brand starts with Twitter, Facebook, or your blog. Social media should take your existing brand and solidify it, galvanize it, and bolster it. Your efforts in social media should be an extension of everything else you do in all departments of your company. Capturing your company's voice and sharing it with the world through social media will open up unique opportunities in all other channels of inbound marketing, including SEO, branding, public relations, sales, and more.

Enterprise social networking allows a company to connect individuals who share similar business interests or activities. Internally, social tools can help employees access information and resources they need to work together effectively and solve business problems. Externally, public social media platforms help an organization stay close to their customers and make it easier to conduct research that they can use to improve business processes and operations.
Though research has shown evidence that social media plays a role in increasing political polarization, it has also shown evidence that social media use leads to a persuasion of political beliefs.  An online survey consisting of 1,024 U.S. participants was conducted by Diehl, Weeks, and Gil de Zuñiga, which found that individuals who use social media were more likely to have their political beliefs persuaded than those who did not.  In particular, those using social media as a means to receive their news were the most likely to have their political beliefs changed.  Diehl et al. found that the persuasion reported by participants was influenced by the exposure to diverse viewpoints they experienced, both in the content they saw as well as the political discussions they participated in.  Similarly, a study by Hardy and colleagues conducted with 189 students from a Midwestern state university examined the persuasive effect of watching a political comedy video on Facebook.  Hardy et. al found that after watching a Facebook video of the comedian/political commentator John Oliver performing a segment on his show, participants were likely to be persuaded to change their viewpoint on the topic they watched (either payday lending or the Ferguson protests) to one that was closer to the opinion expressed by Oliver.  Furthermore, the persuasion experienced by the participants was found to be reduced if they viewed comments by Facebook users which contradicted the arguments made by Oliver. 
YouTube is the world’s largest video-sharing social networking site that enables users to upload and share videos, view them, comment on them and like them. This social network is accessible across the globe and even enables users to create a YouTube channel where they can upload all their personally recorded videos to showcase to their friends and followers.
Bo Han, a social media researcher at Texas A&M University-Commerce, finds that users are likely to experience the "social media burnout" issue. Ambivalence, emotional exhaustion, and depersonalization are usually the main symptoms if a user experiences social media burnout. Ambivalence refers to a user's confusion about the benefits she can get from using a social media site. Emotional exhaustion refers to the stress a user has when using a social media site. Depersonalization refers to the emotional detachment from a social media site a user experiences. The three burnout factors can all negatively influence the user's social media continuance. This study provides an instrument to measure the burnout a user can experience, when her social media "friends" are generating an overwhelming amount of useless information (e.g., "what I had for dinner", "where I am now").
Isabelle agrees. “Constant screen time damages your ability to see, and it also causes internal damage, such as anxiety.” Studies have shown that social media use can negatively affect mental wellbeing, and adolescents are particularly susceptible: one nationally representative survey of US 13- to 18-year-olds linked heavier social media use to depression and suicide, particularly in girls. And 41% of the Gen Z teens surveyed by Hill Holliday reported that social media made them feel anxious, sad or depressed.
One of the biggest mistakes retailers make is to open up accounts on every social media platform they think is relevant and then leave them alone with no activity. Having an account with any of the social media platforms does not mean your business is into social media any more than owning golf clubs makes you ready for the PGA. In fact, social media users are turned off by the retailer who opens accounts and does not engage with clients and the public and consequently become labeled a pretender.
In a study examining the potential polarizing effects of social media on the political views of its users, Mihailidis and Viotty suggest that a new way of engaging with social media must occur to avoid polarization. The authors note that media literacies (described as methods which give people skills to critique and create media) are important to using social media in a responsible and productive way, and state that these literacies must be changed further in order to have the most effectiveness. In order to decrease polarization and encourage cooperation among social media users, Mihailidis and Viotty suggest that media literacies must focus on teaching individuals how to connect with other people in a caring way, embrace differences, and understand the ways in which social media has a realistic impact on the political, social, and cultural issues of the society they are a part of.
Younger generations are becoming more involved in politics due to the increase of political news posted on social media. Due to the heavier use of social media among younger generations, they are exposed to politics more frequently, and in a way that is integrated into their online social lives. Social media was influential in the widespread attention given to the revolutionary outbreaks in the Middle East and North Africa during 2011. During the Tunisian revolution in 2011, people used Facebook to organize meetings and protests. However, there is debate about the extent to which social media facilitated this kind of change.
A unique way to create revenue in collaboration with a brand is to co-create a physical product, collection or range. We see this type of influencer monetization across every niche, from fashion capsule collections and co-branded beauty products to food, fitness, travel and health products. A great example of this is makeup artist and beauty YouTuber Jaclyn Hill’s collaboration with cosmetics brand Becca.
As social media usage has become increasingly widespread, social media has to a large extent come to be subjected to commercialization by marketing companies and advertising agencies. Christofer Laurell, a digital marketing researcher, suggested that the social media landscape currently consists of three types of places because of this development: consumer-dominated places, professionally dominated places and places undergoing commercialization. As social media becomes commercialized, this process have been shown to create novel forms of value networks stretching between consumer and producer in which a combination of personal, private and commercial contents are created.
This is part of a wider trend. According to a study by US marketing firm Hill Holliday of Generation Z – people born after 1995 – half of those surveyed stated they had quit or were considering quitting at least one social media platform. When it comes to Gen Z’s relationship to social media, “significant cracks are beginning to show”, says the firm’s Lesley Bielby.
