Doug Hall says you should focus on one "overt" benefit and not try to be all things to all people. The book states that "analysis of four thousand concepts indivdates that the greater the number of benefits promised, the lower your chances of success." People talk about writing marketing copy that emphasizes the benefits and not the features. But Hall goes one step farther: focus on a single, overt benefit. "The more you focus on doing one thing great, the greater your probability of success." He asks why people choose particular restaurants. Usually it's because they are famous for one dish or specialty. Great restaurants don't try to be all things to all people. In my case that's true. The main reason I ever want to go to Ruby River is for their giant coconut shrimp with orange marmelade sause.
