Description of the Product:

The Newsfeed is a key element for Facebook, as it is the page a user is taken to as soon as they log in. It has a scroll-through style that shows friend activity, relevant and recommended content, as well as advertisements. This is where the most action takes place, and was implemented in order that the user would not have to navigate to a specific friend's timeline to see what they have been up to. Rather, they can get a variety of information aggregated in one place.


As with most FB products/features the goal is to promote user engagement.

Customer Journey:

The journey is simple as mentioned above: once the use logs on, he is immediately taken to the Newsfeed. Hence, we can neglect awareness, acquisition, and activation (since we can readily assume the user has already registered an account) to focus on engagement and retention.


  • For engagement, I think the main thing we can measure the average number of interactions a user has per visit to the Newsfeed. That is, how many times they like, comment, share, or post content per visit. We can perhaps break this down further to see which type of interaction is most prevalent. This is useful to gauge the how the presented content captivates the user - it could be a sign of how well the algorithm that determines relevance/recommendations is performing.
  • We can also measure the average time users spend on the Newsfeed. A limitation to this is measure is if the user is idle on the page (maybe left it open while eating lunch in the other room). We can simply dismiss these cases by excluding those who have not scrolled for longer than 5 minutes (which I think is possible to extract).
  • For retention, it would not be wise to measure visits per week, as users are automatically taken to the page; they can sign in and be brought to the page without engaging with it. So instead, we could measure the number average of interactions (interactions defined the same as the first bullet) per user per week.

I don't want to get into the evaluation and ranking of these metrics because I think that is out of the scope of my focus. Hopefully this is an adequate answer but please give me some feedback since I am still practicing and working on getting better!

Good answer ; but for these type of questions you need to prioritize your metrics It also shows your prioritization skills as a PM.

Prioritized Metrics

1. avg dwell time of the user (how much time a user is spending scrolling on newsfeed)

2. # of interactions / user - # of likes / comments / shares (would help measure the quality of the content generated in the newsfeed)

3. DAU & MAU accessing newsfeed

4. Churn Rate

5. # of escalations / bugs received per week in regards to newsfeed

6. avg revenue generated / user (the more time spend by user, the revenue genrate will increase *assuming its CPM)
