What is one of the defining features of Facebook Feed Targeting?

One of the defining features of Facebook Feed Targeting is its ability to ensure that only targeted users see specific posts. This targeting capability allows marketers to reach particular segments of their audience based on a variety of criteria, such as demographics, interests, and behaviors. By honing in on specific user groups, businesses can enhance engagement and effectiveness of their content, as the messages resonate more with the intended audience. This increases the likelihood of achieving marketing objectives, such as driving conversions or brand awareness, by delivering relevant content to the right people at the right time.

The other options describe features or functions that do not align with the core purpose of Facebook Feed Targeting. For instance, reducing the number of posts published is not a direct outcome of targeting; visibility management does not limit the information to only the author; and sharing in multiple languages pertains to content accessibility rather than targeting specific audiences. Overall, option C accurately represents a fundamental characteristic of Facebook Feed Targeting.
