UPSjobs Problem Solved / TMP Worldwide
UPS jobs, a social program created with advertising agency TMP Worldwide, reached 4 million job seekers in one year. It included employee videos of actual UPSers, email, employee retention marketing, college recruitment, search engine optimization, job boards, search engine marketing, and social media sites including MySpace, Friendster, Facebook, YouTube, radio, cable television, text messaging, mobile marketing, and the newspaper. 30,000 responses came from mobile marketing alone. Since January the program has generated 345,000 job appications, at a cost of 75 to 80% less than traditional newspaper ads in many cases.
