BKF Consulting recommends three strategies to improve Burgie's Coffee brand and increase profits: 1) Direct-mail marketing using postcards to existing and new customers, 2) Distributing free coffee samples to promote brand awareness, and 3) Installing new signage at key intersections near locations to boost visibility. The combination of effective marketing tactics is expected to have greater rewards than any single approach alone and help Burgie's become more successful in the competitive Ames market.
