We wanted to help you learn which type of stories work best, so we came up with a way you can easily tell what type of content works for your audience, and we’ve called it a Completion Rate, 

The questions we wanted to help you answer were: 
What type of Stories content captures people's attention?
What type of Stories content holds people's attention the longest? 

We calculate the genuine engagement on your Stories, which means that we tell you the percentage of people that started watching your story and stayed until the end. 

Checking your Plann analytics you’ll soon start to discover:
- The length of videos that seem to hold the most amount of watchers.
- If photos or videos are more effective for a higher completion rate. 

We recommend testing and reviewing your metrics to make the most out of Instagram - the biggest, visual, marketing tool on the planet.
