Marketing executives remain cool to social media. To wit, more than two-thirds (67%) of marketers consider themselves beginners at using social media for marketing purposes, according to a new survey by the Marketing Executives Networking Group (MENG). The survey, which was conducted online, garnered 139 responses. In a somewhat troubling sign, more than 87% of respondents are not regularly measuring the ROI of their social media marketing efforts. “While many marketers are worried they’re missing the boat, in reality even the Fortune 500 companies don’t feel they’ve mastered social media just yet,” said Richard Guha, Chairman of MENG, in a news release. While more than 67% of respondents said they will increase their social media advertising budget in 2009, nearly 80% said social media is not a fully integrated component of their marketing programs.
