On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
Because it appeared quickly, social media has developed a reputation by some for being a passing marketing interest, and therefore, an unprofitable one. The statistics, however, illustrate a different picture. According to Hubspot, 92% of marketers in 2014 claimed that social media marketing was important for their business, with 80% indicating their efforts increased traffic to their websites. And according to Social Media Examiner, 97% of marketers are currently participating in social media—but 85% of participants aren’t sure what social media tools are the best to use.
Social media marketing is the use of social media platforms and websites to promote a product or service. Although the terms e-marketing and digital marketing are still dominant in academia, social media marketing is becoming more popular for both practitioners and researchers. Most social media platforms have built-in data analytics tools, which enable companies to track the progress, success, and engagement of ad campaigns. Companies address a range of stakeholders through social media marketing, including current and potential customers, current and potential employees, journalists, bloggers, and the general public. On a strategic level, social media marketing includes the management of a marketing campaign, governance, setting the scope (e.g. more active or passive use) and the establishment of a firm's desired social media "culture" and "tone."
