Whereas Kaplan, Haenlein and others reduce the role of marketers to crafting the initial viral message and seeding it, futurist and sales and marketing analyst Marc Feldman, who conducted IMT Strategies' viral marketing study in 2001, carves a different role for marketers which pushes the 'art' of viral marketing much closer to 'science'.
'The influencers in order to communicate marketing messages to the audiences you seek to reach'. In business, it is indicated that people prefer interaction with humans to a logo. Therefore, it seems that influencers are on behalf of a company to build up a relationship between the brand and their customers. Companies would be left behind if they neglected the trend of influencers in viral marketing, as over 60% of global brands have used influencers in marketing in 2016. The influencer types come along with the level of customers' involvement in companies' marketing.

The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016).
