Which option can be applied when publishing a post with a link through Hootsuite Composer?

When publishing a post with a link through Hootsuite Composer, the ability to track link clicks is an essential feature. This allows users to gain insights into how well their links are performing by measuring engagement. Tracking link clicks provides valuable data about user interactions, helping in analyzing the effectiveness of content and campaigns. By utilizing this feature, social media managers can adjust their strategies based on audience behavior, aiming for improved engagement over time.

The other choices, while useful in various contexts, do not directly pertain to the specific functionality of managing link interactions within a post. Changing the post format, scheduling posts for future times, and replacing images are features that may enhance the post's presentation or timing but do not contribute to the tracking and analysis of user engagement with the links shared in those posts.
