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. 
Another ethical controversy associated with search marketing has been the issue of trademark infringement. The debate as to whether third parties should have the right to bid on their competitors' brand names has been underway for years. In 2009 Google changed their policy, which formerly prohibited these tactics, allowing 3rd parties to bid on branded terms as long as their landing page in fact provides information on the trademarked term. Though the policy has been changed this continues to be a source of heated debate.
8. Better Search Engine Rankings. SEO is the best way to capture relevant traffic from search engines, but the requirements for success are always changing. It’s no longer enough to regularly update your blog, ensure optimized title tags and meta descriptions, and distribute links pointing back to your site. Google and other search engines may be calculating their rankings using social media presence as a significant factor, because of the fact that strong brands almost always use social media. As such, being active on social media could act as a “brand signal” to search engines that your brand is legitimate, credible, and trustworthy. That means, if you want to rank for a given set of keywords, having a strong social media presence could be almost mandatory.
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.
Digital marketing is defined by the use of numerous digital tactics and channels to connect with customers where they spend much of their time: online. From the website itself to a business's online branding assets -- digital advertising, email marketing, online brochures, and beyond -- there's a spectrum of tactics that fall under the umbrella of "digital marketing."
