Digital marketing has made a significant penetration across different industry verticals in the last three years. Surprisingly, it has become a household concept which was very unlikely a few years back. Small, medium and large scale businesses have identified it as a very powerful advertising tool. Conventional advertising always had disadvantages which were mainly associated with its limited reach and audience. Online marketing on the other hand has a huge advantage in terms of its massive reach across a global audience. Today, most of the Fortune 500 companies have partnered with digital marketing giants to launch powerful promotional campaigns for their business.
