So keeping up with the ever-changing algorithm on Facebook can be quite challenging. Many have believed in the ‘Edgerank Formula’ which ranks stories on affinity, weight and time. Now Facebook have launched some changes, which means that the Edgerank Formula, as we know it, has changed.
Previously, the stories in your news feed have been showed chronologically. This also meant that you probably were missing some stories (unless you’re watching your news feed 24/7). With Story Bumping, Facebook has changed the order of the stories, so stories that are a few days old, but relevant to you, will appear in the top of your feed again. In other words; these stories are not new – but they are new to you!
Facebook stated that they have tested the new algorithm and they experienced an 8 % increase in the activity of stories posted by pages.
The stories in your new feed will also be affected by the The Last Actor function. This function looks at the latest 50 people you’ve engaged with – fx by liking their updates or even just stalking their profile. These 50 people will be showed more regularly in your feed and ticker. This will also apply for pages – if someone often engages with your page, they would presumably see a lot more of your future stories.
Last Actor have already been rolled out to Danish Facebook users on mobile and web, while Story Bumping will be added to mobile soon.
