Which of the following strategies is least likely to be guided by market research?

Establishing generic slogans is least likely to be guided by market research because the process of creating such slogans typically relies on broad, general concepts rather than specific data about the target audience. Generic slogans often aim to appeal to a wide range of people without the nuance that market research provides, which identifies specific demographics, preferences, and behaviors of a target market.

In contrast, identifying target demographics, refining campaign messaging, and choosing appropriate advertising channels are all strategies directly informed by detailed market research. These approaches involve analyzing data to understand the audience better, tailoring messages that resonate with them, and selecting media that effectively reach those audiences. By utilizing market research, marketers can ensure their strategies are targeted and relevant, ultimately leading to more successful campaigns.
