Yesterday, at a panel I moderated (充当调解人) in San Francisco, Donna Wells, Mint. con’s chief marketing officer, stunned a room full of digital marketing pros by noting that she really didn’t have much of a marketing budget. Mint. com has gone from zero to 1.5 million users in two years with no ad campaign, save a mid—five—figures sum spent on search engine terms. Rather than purchase traffic, it has pursued the same type of strategy that food trucks and online magazines do : Using free social media and piggybacking (附带) on popular new communications technology. Mint. com has more than 36,000 Facebook fans and 19,000 Twitter followers, a well - trafficked blog, and a popular iPhone application. How has Mint. con successfully promoted its fame in the last two years.’
A. With ad campaigns. B. By purchasing traffic. C. By using free social media. D. Through cooperation with other websites.
