Context
First off lets just briefly establish what Facebook stories is and even more importantly why users use it. Facebook stories is a feature that allows users to share short form video clips and photos with their friends that disappear after 24 hours. There is a strip along the top of the timeline where users can see thumbnaisl for stories from their friends and tap into them to view, comment, and interact with them. Stories allow users to share much more daily casual moments in their lives with friends that aren't polished enough to be fully deserving of a permanent post.
Before we dive into the nitty gritty, let's first take a step back and make sure we understand the context surrounding the bigger picture. Facebook's mission statement is to bring the world closer together and give people the power to build community. Facebook Stories helps further this mission statement by giving users an avenue to share and view more casual less polished moments from their and their friends' lives.
Users
When we're thinking about goals for this product and what they may mean we need to keep in mind there are two different types of users for this feature:
- Viewers - The users who are viewing and interacting with stories
- Creators - The users creating and posting the content in the stories
Creators:
- Average number of stories created per user per day
- Average number of unwatched stories available per session
- Total # of stories created per day
Viewers:
- Average number of story views per session
- % of users who have viewed at least 3 stories per day
- Average number of interactions per story
- Average number of sessions per week for users who have viewed at least 5 stories
- Average number of sessions per week for users who have viewed less than 5 stories
- % of users who viewed at least 5 stories last week and had 5 sessions who also came back and had at least 5 sessions this week
- % of users who viewed less than 5 stories last week and had 5 sessions who also came back and had at least 5 sessions this week
- While intentional, all of our above metrics are very high level. They don't offer us much granularity into how Facebook stories performs amongst different segments. For example, it could perform 10x as well amongst younger users who are more familiar with short form content from IG stories and snap where as some of the older users on the platform might not engage with it as much.
- Facebook is a mature and complex platform with a lot of features and functionality. Adding new features inherently competes with older features for user attention. We should examine how Facebook Stories impacts engagement with other features on the platform. I would be concerned if Facebook stories engagement went up but overall time one the platform per user went down.
- We are trying to measure the lift in retention as a result of stories, but at the same time the more engaged users are more likely to use stories to begin with. It would've been nice to measure on the increase in engagement / retention caused by stories on a per user level when rolling it out.
- One item we never touched upon here is monetization, which as a mature product should be at the forefront of Facebook's thinking. I do think Stories is really an engagement / retention play but there is an opportunity worth exploring here for sponsored stories.
Starting with context:
Customers:
Facebook stories and videos and images and added by customers to share daily happenings that have in and around their place mostly to get likes and appreciation from their friends and family
Stories come with links where users can end up purchasing the product/service, reading
Companies:
another type of group of users who also who the company should want to share updates about product releases or discounts or just trying to engage with their customer
Company ads/stories come up links where user can do the following
Buy the product after visiting the website
Engage with the post by adding a comment
Like the post and then browse the company’s page
Browse the company’s website page (might decide to purchase company’s products later)
Goals:
One of the most significant revenue sources for Facebook is advertising and of course, making use of this data
So the success metric would be the increased engagement measured by time on the app. (Increase)
Increase in Avg. time per session because of stories
Avg. increase in revenue because of stories
Metrics:
I would break down the engagement of Facebook stories into different stages user is in their journey
Demand-side (consumer of stories) | Supply side (creator of stories) | |
Adoption | Number of users who saw at least stories/ Total FB active users User creation to stories through focus groups | User conversion in funnel (Clicked on story/Total FB active users, Created a story/Total FB active users & finally posted a story/Total active FB users) Users who tried stories / Total FB active users Users who tried stories / Total active users |
Engagement |

Retention |

Trade-off metrics |

I would run an AB with and without AB and try to understand how users are reacting to the product if the product is intuitive and creates customer delight.
