3. The brand (商标) name puts a face on every company. Names like McDonald's, GM, Apple, Intel, and a large number of others have long become very popular. They've also given customers a point of reference when thinking about a company. Good brand names might help companies avoid heavy costs and bring them greater profits.
Usually companies create names that are easy to learn and remember. Firstly, the name should create interest. Rhymes (押韵) and humor are some ways to gain interest, but there are others as well. Think about your customers and what would interest them. Secondly, the name should present a picture or image. People remember them most because the name is stored in pictures and words. Thirdly, the name should be meaningful. It can be done with lots of advertising, but names that are themselves more meaningful to customers are more easily stored in memory. More important, the name should have meaningful associations that show the benefits customers want. Then the name should have some emotion. Emotional associations are easier to learn and remember. The Love Boat, for instance, is very easy to remember. Finally, the name should be simple so that it is easier to learn and remember.
