A defined audience should be specific enough to reach which of the following?

A defined audience should be specific enough to reach the people most interested in your content because this approach allows for targeted messaging that resonates with the intended demographic. When you tailor your audience, you're able to leverage insights about their behaviors, interests, and preferences, which enhances the relevance of your advertising or content. This targeted approach not only increases engagement but also improves the effectiveness of your campaigns by ensuring that the right message is delivered to the right people.

Focusing on the broad audiences mentioned in the other options may dilute the effectiveness of your message. Trying to reach everyone on Facebook, for instance, would likely lead to low engagement and wasted resources as your content would not cater specifically to anyone’s needs or interests. Similarly, addressing the most readers regardless of interest can cause your content to miss the mark entirely, appealing to those who may not appreciate or engage with what you're offering. Lastly, limiting your audience only to existing followers restricts growth and prevents reaching new potential customers who may have a strong interest in your content, thus hindering the overall audience expansion strategy.
