Social media can be used not only as public relations and direct marketing tools but also as communication channels targeting very specific audiences with social media influencers and social media personalities and as effective customer engagement tools. Technologies predating social media, such as broadcast TV and newspapers can also provide advertisers with a fairly targeted audience, given that an ad placed during a sports game broadcast or in the sports section of a newspaper is likely to be read by sports fans. However, social media websites can target niche markets even more precisely. Using digital tools such as Google Adsense, advertisers can target their ads to very specific demographics, such as people who are interested in social entrepreneurship, political activism associated with a particular political party, or video gaming. Google Adsense does this by looking for keywords in social media user's online posts and comments. It would be hard for a TV station or paper-based newspaper to provide ads that are this targeted (though not impossible, as can be seen with "special issue" sections on niche issues, which newspapers can use to sell targeted ads).
Mobile devices have become increasingly popular, where 5.7 billion people are using them worldwide . This has played a role in the way consumers interact with media and has many further implications for TV ratings, advertising, mobile commerce, and more. Mobile media consumption such as mobile audio streaming or mobile video are on the rise – In the United States, more than 100 million users are projected to access online video content via mobile device. Mobile video revenue consists of pay-per-view downloads, advertising and subscriptions. As of 2013, worldwide mobile phone Internet user penetration was 73.4%. In 2017, figures suggest that more than 90% of Internet users will access online content through their phones.
With the development of this system, the price is growing under the high level of competition. Many advertisers prefer to expand their activities, including increasing search engines and adding more keywords. The more advertisers are willing to pay for clicks, the higher the ranking for advertising, which leads to higher traffic. PPC comes at a cost. The higher position is likely to cost $5 for a given keyword, and $4.50 for a third location. A third advertiser earns 10% less than the top advertiser, while reducing traffic by 50%. The investors must consider their return on investment and then determine whether the increase in traffic is worth the increase.
A key benefit of using online channels for marketing a business or product is the ability to measure the impact of any given channel, as well as how visitors acquired through different channels interact with a website or landing page experience. Of the visitors that convert into paying customers, further analysis can be done to determine which channels are most effective at acquiring valuable customers.
Many brands are now heavily using this mobile app to boost their marketing strategy. Instagram can be used to gain the necessary momentum needed to capture the attention of the market segment that has an interest in the product offering or services. As Instagram is supported by Apple and android system, it can be easily accessed by smartphone users. Moreover, it can be accessed by the Internet as well. Thus, the marketers see it as a potential platform to expand their brands exposure to the public, especially the younger target group. On top of this, marketers do not only use social media for traditional Internet advertising, but they also encourage users to create attention for a certain brand. This generally creates an opportunity for greater brand exposure. Furthermore, marketers are also using the platform to drive social shopping and inspire people to collect and share pictures of their favorite products. Many big names have already jumped on board: Starbucks, MTV, Nike, Marc Jacobs, and Red Bull are a few examples of multinationals that adopted the mobile photo app early. Fashion blogger Danielle Bernstein, who goes by @weworewhat on Instagram, collaborated with Harper's Bazaar to do a piece on how brands are using Instagram to market their products, and how bloggers make money from it. Bernstein, who currently has one and a half million followers on Instagram, and whose "outfit of the day" photos on Snapchat get tens of thousands of screenshots, explained that for a lot of her sponsored posts, she must feature the brand in a certain number of posts, and often cannot wear a competitor's product in the same picture. According to Harper's Bazaar, industry estimates say that brands are spending more than $1 billion per year on consumer-generated advertising. Founder of Instagram Kevin Systrom even went to Paris Fashion week, going to couture shows and meeting with designers to learn more about how style bloggers, editors, and designers are currently dominating much of the content on his application.
The code of ethics that is affiliated with traditional marketing can also be applied to social media. However, with social media being so personal and international, there is another list of complications and challenges that come along with being ethical online. With the invention of social media, the marketer no longer has to focus solely on the basic demographics and psychographics given from television and magazines, but now they can see what consumers like to hear from advertisers, how they engage online, and what their needs and wants are. The general concept of being ethical while marking on social network sites is to be honest with the intentions of the campaign, avoid false advertising, be aware of user privacy conditions (which means not using consumers' private information for gain), respect the dignity of persons in the shared online community, and claim responsibility for any mistakes or mishaps that are results of your marketing campaign. Most social network marketers use websites like Facebook and MySpace to try to drive traffic to another website. While it is ethical to use social networking websites to spread a message to people who are genuinely interested, many people game the system with auto-friend adding programs and spam messages and bulletins. Social networking websites are becoming wise to these practices, however, and are effectively weeding out and banning offenders.
Social media often feeds into the discovery of new content such as news stories, and “discovery” is a search activity. Social media can also help build links that in turn support into SEO efforts. Many people also perform searches at social media sites to find social media content. Social connections may also impact the relevancy of some search results, either within a social media network or at a ‘mainstream’ search engine.
Social media marketing provides organizations with a way to connect with their customers. However, organizations must protect their information as well as closely watch comments and concerns on the social media they use. A flash poll done on 1225 IT executives from 33 countries revealed that social media mishaps caused organizations a combined $4.3 million in damages in 2010. The top three social media incidents an organization faced during the previous year included employees sharing too much information in public forums, loss or exposure of confidential information, and increased exposure to litigation. Due to the viral nature of the Internet, a mistake by a single employee has in some cases shown to result in devastating consequences for organizations. An example of a social media mishap includes designer Kenneth Cole's Twitter mishap in 2011. When Kenneth Cole tweeted, "Millions are in uproar in #Cairo. Rumor has they heard our new spring collection is now available online at [Kenneth Cole's website]". This reference to the 2011 Egyptian revolution drew an objection from the public; it was widely objected to on the Internet. Kenneth Cole realized his mistake shortly after and responded with a statement apologizing for the tweet.
YouTube is another popular avenue; advertisements are done in a way to suit the target audience. The type of language used in the commercials and the ideas used to promote the product reflect the audience's style and taste. Also, the ads on this platform are usually in sync with the content of the video requested, this is another advantage YouTube brings for advertisers. Certain ads are presented with certain videos since the content is relevant. Promotional opportunities such as sponsoring a video is also possible on YouTube, "for example, a user who searches for a YouTube video on dog training may be presented with a sponsored video from a dog toy company in results along with other videos." YouTube also enable publishers to earn money through its YouTube Partner Program. Companies can pay YouTube for a special "channel" which promotes the companies products or services.
Social Media for Content Promotion — Social media marketing is a perfect channel for sharing your best site and blog content with readers. Once you build a loyal following on social media, you'll be able to post all your new content and make sure your readers can find new stuff right away. Plus, great blog content will help you build more followers. It's a surprising way that content marketing and social media marketing benefit each other.
In 2007, U.S. advertisers spent US $24.6 billion on search engine marketing. In Q2 2015, Google (73.7%) and the Yahoo/Bing (26.3%) partnership accounted for almost 100% of U.S. search engine spend. As of 2006, SEM was growing much faster than traditional advertising and even other channels of online marketing. Managing search campaigns is either done directly with the SEM vendor or through an SEM tool provider. It may also be self-serve or through an advertising agency. As of October 2016, Google leads the global search engine market with a market share of 89.3%. Bing comes second with a market share of 4.36%, Yahoo comes third with a market share of 3.3%, and Chinese search engine Baidu is fourth globally with a share of about 0.68%.
In 2012 during Hurricane Sandy, Gap sent out a tweet to its followers telling them to stay safe but encouraged them to shop online and offered free shipping. The tweet was deemed insensitive, and Gap eventually took it down and apologized. Numerous additional online marketing mishap examples exist. Examples include a YouTube video of a Domino's Pizza employee violating health code standards, which went viral on the Internet and later resulted in felony charges against two employees. A Twitter hashtag posted by McDonald's in 2012 attracting attention due to numerous complaints and negative events customers experienced at the chain store; and a 2011 tweet posted by a Chrysler Group employee that no one in Detroit knows how to drive. When the Link REIT opened a Facebook page to recommend old-style restaurants, the page was flooded by furious comments criticizing the REIT for having forced a lot of restaurants and stores to shut down; it had to terminate its campaign early amid further deterioration of its corporate image.
In early 2012, Nike introduced its Make It Count social media campaign. The campaign kickoff began YouTubers Casey Neistat and Max Joseph launching a YouTube video, where they traveled 34,000 miles to visit 16 cities in 13 countries. They promoted the #makeitcount hashtag, which millions of consumers shared via Twitter and Instagram by uploading photos and sending tweets. The #MakeItCount YouTube video went viral and Nike saw an 18% increase in profit in 2012, the year this product was released.
Facebook pages are far more detailed than Twitter accounts. They allow a product to provide videos, photos, longer descriptions, and testimonials where followers can comment on the product pages for others to see. Facebook can link back to the product's Twitter page, as well as send out event reminders. As of May 2015, 93% of businesses marketers use Facebook to promote their brand. A study from 2011 attributed 84% of "engagement" or clicks and likes that link back to Facebook advertising. By 2014, Facebook had restricted the content published from business and brand pages. Adjustments in Facebook algorithms have reduced the audience for non-paying business pages (that have at least 500,000 "Likes") from 16% in 2012 down to 2% in February 2014. 
LinkedIn, a professional business-related networking site, allows companies to create professional profiles for themselves as well as their business to network and meet others. Through the use of widgets, members can promote their various social networking activities, such as Twitter stream or blog entries of their product pages, onto their LinkedIn profile page. LinkedIn provides its members the opportunity to generate sales leads and business partners. Members can use "Company Pages" similar to Facebook pages to create an area that will allow business owners to promote their products or services and be able to interact with their customers. Due to spread of spam mail sent to job seeker, leading companies prefer to use LinkedIn for employee's recruitment instead using different a job portal. Additionally, companies have voiced a preference for the amount of information that can be gleaned from a LinkedIn profile, versus a limited email.
Before online marketing channels emerged, the cost to market products or services was often prohibitively expensive, and traditionally difficult to measure. Think of national TV ad campaigns, which are measured through consumer focus groups to determine levels of brand awareness. These methods are traditionally lso not well-suited to controlled experimentation. Today, anyone with an online business (as well as most offline businesses) can participate in online marketing by creating a website and building customer acquisition campaigns at little to no cost. Those marketing products and services also have the ability to experiment with optimization to fine-tune their campaigns’ efficiency and ROI.
