E-tailing sites attract traffic in very large numbers of the shoppers. These shoppers are either in the purchase mode or the search mode. This traffic could be monetised. Brands can be promoted by properly targeted and relevant ads on these sites. App-based taxi operators put ads on e-commerce sites. Apart from Facebook and Google, this is another medium to reach out to people. The brand advertiser and the site both gain in terms of awareness and business. In future, the e-tailing sites will form an important component of the media mix for the brand marketers.This media will grow bigger. It is akin to point-of-sale advertising in a modern retail outlet. Flipkart and Snapdeal have already started accepting online ads, and others may follow suit.
