Why digital media marketing have become an integral part to boost your products in market?

I agree with Mamta also adding few points. Online advertising has developed these years that it is now possible to target the prospective buyer based on their interest, geographical location, language, age group etc. Also the ROI is clearly measurable from the reports from the online ad agencies. These efficiencies made the way to shift from traditional marketing means to the digital marketing.

Very simple, the consumers are spending more and more time on digital and online content so that is where you need to be to catch their attention.

Accessible to many and easily managed.
