When setting a goal for Instagram Stories, it's important to first identify the purpose of using this feature. Is it to increase brand awareness, drive website traffic, or boost engagement with followers? Once the goal is established, it's important to track relevant metrics to evaluate the success of the Stories. This could include metrics such as views, taps forward and back, and replies. Regarding the trade-off question of having Stories expire every hour instead of 24 hours, it's important to consider the impact on user behavior and experience. While expiring Stories more frequently could create a sense of urgency and increase engagement, it could also lead to users feeling overwhelmed or frustrated by the constant need to create new content. Ultimately, the decision would depend on the specific goals and target audience of the Instagram account in question.
