Nowadays, for corporations and organizations, the network social media means a huge commercial landscape. For consumers, social media enables “users to produce and share on-line content, radically changing the traditional communication paradigms and turning the former mass information consumers to the present information producers” .
In terms of online marketing, consumers’ role has changed in that they now “are able to interact with brands, corporations and other consumers” . And this “has altered the marketing environment in which corporations, marketers and advertisers operate. ” For corporations, the online environment for marketing is not as easy as before.
According to a global online survey among 300 consumers of digital technology products, “the most reliable information sources were friends, family or word of mouth from someone they knew, followed by expert product reviews, and product reviews written by other consumers; the most unreliable information sources were advertising or infomercials, automated recommendations based on purchasing patterns or retailers.”  In other words, consumers can hardly trust advertisements, while they trust friends’ recommendations. Additionally, social media plays an important role during the process of opinion sharing among consumers. The survey also shows that Facebook, Twitter, Amazon and E-bay are the most popular social media websites for reviews. “The highest number of respondents indicated Facebook as the website where, upon purchase, they have posted the product review, opinion or comment.”  From the above, it seems that online discourse power belongs to consumers, and SNNs are indispensable online platform for consumers to share reviews.
However, does this mean that corporations and organizations lose control of their reputation online?
During the process of spreading information, the role of opinion leaders, like stars, celebrities and experts, is relatively important. Corporations and organizations can make use of it. “The identification of influential users in on-line social network can support corporations in designing and targeting marketing campaigns, as influential gate-keepers and diffusers of information can ignite epidemics of word of mouth.”  Because “when people perform an action, they may be influenced by what they have heard of it outside of the online social network or they may be genuinely influenced by seeing their social contacts performing that action.”  Hence, corporations can buy the influential people over in order to influence the information spread online.
Additionally, some companies sell “Twitter followers”, “Facebook friends”, in order to help corporations to control public opinion. These “Twitter followers” and “Facebook friends” spread what the corporations want. Their discourse may affect consumers’ idea.
Conclusively, although consumers play important role online, their behaviors can still be deeply influenced by corporations and organizations.
