Facebook has a new experiment running, that appears to be aimed at increasing engagement on the right-hand column of some pages. In the “Suggestions” box on the right-hand side of some pages, including the Games dashboard and photos, it is showing photos from your friends’ albums and notices about unread messages.
The box has previously shown suggested friends or Pages you might want to become a fan of. The introduction of content from your friends could make that part of the page more interesting — the only other content in the column is advertising. If users get more used to looking at Suggestions for interesting material, overall engagement for the feature could increase, and they might be more likely to notice and click on the ads.
Strangely, though, Facebook seems to be showing photos from many months ago. We’ll probably see a variety of content as the test progress.
