In 2007, Google announced a campaign against paid links that transfer PageRank.[30] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat any nofollow links, in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[31] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated JavaScript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[32]

“In conclusion, this research illuminates how content characteristics shape whether it becomes viral. When attempting to generate word of mouth, marketers often try targeting “influentials,” or opinion leaders (i.e., some small set of special people who, whether through having more social ties or being more persuasive, theoretically have more influence than others). Although this approach is pervasive,recent research has cast doubt on its value (Bakshy et al. 2011; Watts 2007) and suggests that it is far from cost effective. Rather than targeting “special” people, the current research suggests that it may be more beneficial to focus on crafting contagious content. By considering how psychological processes shape social transmission, it is possible to gain deeper insight into collective outcomes, such as what becomes viral.”
