FACEBOOK ALGORITHM OBSERVATION #34
A page follower has not seen any page posts in her timeline for a long time. A picture she sent via messenger was posted on that page, with some captions. This post shows up in her timeline. Why this post?
Two potential explanations:
1. Because she is currently located in the country mentioned in that post
2. Because algorithm noticed the photo she sent and the photo in the post figuring the photo has something to do with her.
In either of these hypotheses it seems FB algo is smart.
