Social media marketing involves the use of social networks, consumer's online brand-related activities (COBRA) and electronic word of mouth (eWOM) to successfully advertise online. Social networks such as Facebook and Twitter provide advertisers with information about the likes and dislikes of their consumers. This technique is crucial, as it provides the businesses with a "target audience". With social networks, information relevant to the user's likes is available to businesses; who then advertise accordingly. Activities such as uploading a picture of your "new Converse sneakers to Facebook" is an example of a COBRA. Electronic recommendations and appraisals are a convenient manner to have a product promoted via "consumer-to-consumer interactions. An example of eWOM would be an online hotel review; the hotel company can have two possible outcomes based on their service. A good service would result in a positive review which gets the hotel free advertising via social media. However, a poor service will result in a negative consumer review which can potentially harm the company's reputation.
One of the main purposes of employing social media in marketing is as a communications tool that makes the companies accessible to those interested in their product and makes them visible to those who have no knowledge of their products. These companies use social media to create buzz, and learn from and target customers. It's the only form of marketing that can finger consumers at each and every stage of the consumer decision journey. Marketing through social media has other benefits as well. Of the top 10 factors that correlate with a strong Google organic search, seven are social media dependent. This means that if brands are less or non-active on social media, they tend to show up less on Google searches. While platforms such as Twitter, Facebook, and Google+ have a larger number of monthly users, the visual media sharing based mobile platforms, however, garner a higher interaction rate in comparison and have registered the fastest growth and have changed the ways in which consumers engage with brand content. Instagram has an interaction rate of 1.46% with an average of 130 million users monthly as opposed to Twitter which has a .03% interaction rate with an average of 210 million monthly users. Unlike traditional media that are often cost-prohibitive to many companies, a social media strategy does not require astronomical budgeting.
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. 
Online marketing is the practice of leveraging web-based channels to spread a message about a company’s brand, products, or services to its potential customers. The methods and techniques used for online marketing include email, social media, display advertising, search engine optimization, Google AdWords and more. The objective of marketing is to reach potential customers through the channels where they spend their time reading, searching, shopping, and socializing online.
Search engines reward you when sites link to yours – they assume that your site must be valuable and you’ll rank higher in search results. And the higher the “rank” of the sites that link to you, the more they count in your own ranking. You want links from popular industry authorities, recognized directories, and reputable companies and organizations.
Engagement in social media for the purpose of a social media strategy is divided into two parts. The first is proactive, regular posting of new online content. This can be seen through digital photos, digital videos, text, and conversations. It is also represented through sharing of content and information from others via weblinks. The second part is reactive conversations with social media users responding to those who reach out to your social media profiles through commenting or messaging. Traditional media such as TV news shows are limited to one-way interaction with customers or 'push and tell' where only specific information is given to the customer with few or limited mechanisms to obtain customer feedback. Traditional media such as physical newspapers, do give readers the option of sending a letter to the editor. Though, this is a relatively slow process, as the editorial board has to review the letter and decide if it is appropriate for publication. On the other hand, social media is participative and open; Participants are able to instantly share their views on brands, products, and services. Traditional media gave control of message to the marketer, whereas social media shifts the balance to the consumer or citizen.
The promotion of products or brands via one or more forms of electronic media. For example, advertising mediums that might be used as part of the digital marketing strategy of a business could include promotional efforts made via the Internet, social media, mobile phones and electronic billboards, as well as via digital and television and radio channels.
