“A clear majority of Americans say social media have no effect at all on their purchasing decisions. Although many companies run aggressive marketing campaigns on social media, 62% in the U.S. say Facebook and Twitter, among other sites, do not have any influence on their decisions to purchase products.  Despite tremendous numbers of Americans using social media institutions such as Facebook, Google+, LinkedIn, and Twitter, only 5% say social media have “a great deal of influence” on their purchasing decisions, while another 30% say these channels have “some influence.” These data, from Gallup’s new State of the American Consumer report, are based on Americans’ self-reported estimates of how much social media campaigns affect their purchasing decisions. While social media may have more influence than some Americans realize or will admit, these data show that relatively few consumers consciously take into account what they learn from social media when making purchases.”
