For Instagram stories, there are a few key metrics and goals that a product manager may want to focus on: 1. Engagement rate: This is a key metric for any social media platform, and it measures the percentage of users who engage with a particular piece of content. For Instagram stories, engagement rate can be measured by looking at the number of users who view a story, as well as the number of users who engage with it (e.g. by swiping up, responding to a poll, etc.). 2. Completion rate: Completion rate measures the percentage of users who watch a story all the way through. This can be a good indicator of how engaging a particular story is, and can help product managers identify which types of content perform best on the platform. 3. Retention rate: Retention rate measures the percentage of users who continue to watch subsequent stories after viewing the first one. This can help product managers understand how well their stories are sequenced and whether users are interested in seeing more. 4. Conversion rate: For businesses using Instagram stories to drive conversions (e.g. by including links to products or services), conversion rate is a key metric. This measures the percentage of users who click through to the website or landing page and actually make a purchase. Overall, the goal for Instagram stories should be to create engaging, compelling content that keeps users coming back for more. By focusing on metrics like engagement rate, completion rate, retention rate, and conversion rate, product managers can gain insights into what works best on the platform and use that information to drive growth and engagement over time.
