A target audience can change as your business grows or as people needs change. New trends, new problems, or new products can attract different people. Many businesses start with one group and later notice interest from another group. This does not mean the old audience is useless. It means you should pay attention and adjust slowly. Watching sales, messages, and feedback helps you notice changes early. Staying flexible helps marketing stay useful instead of outdated. Should businesses review their audience from time to time regularly?
