In simplistic terms, Digital Marketing is the promotion of products or brands via one or more forms of electronic media. Digital marketing differs from traditional marketing in that it involves the use of channels and methods that enable an organization to analyze marketing campaigns and understand what is working and what isn’t – typically in real time. In a broader sense, the Internet is the heart of digital marketing. The Internet offers several applications such as web, email, IM, RSS, video which can be leveraged by marketers to launch campaigns. The explosive growth of smartphones and tablets has meant that mobile has emerged as a widely accepted digital marketing channel in recent times. And last but not least, social media has been a great ambassador to the cause of digital marketing. While the primary motivation for social networks was in-person interaction, leading social networks such as Facebook and Twitter have transformed into valuable digital marketing tools.
