Noticed a recent change in the latest FB iPhone App which was presumably done for the purpose of increasing user engagement with stories in the news feed. Before the change, here is how a sample story would look like:
As shown above, the Like, Comment, and Share calls to action are displayed as simple word links. In addition, the number of likes and comments for the story are shown in a similar treatment with the same amount of prominence and with the same color.
With the most recent iOS FB app update, here is how this component looks like:
– The biggest change is the change of word links as the primary CTAs (call to action) to using buttons with icons as the primary CTAs. This is a very huge and radical change. One well-accepted best-practise of conversion for site/app flows is the usage of buttons instead of text links and another best-practise is the usage of icons instead of just words. Here, Facebook is adding two very important components: both the conversion of the word to a button, and the addition of the corresponding CTA icon.
– In terms of overall screen real estate, the primary CTAs are taking up more space. Also, the component that conveys the amount of likes and comments has increased in size. Instead of showing the amount of likes and comments next to their corresponding icons, they are now shown next to the words Likes and Comments.
Is this a good idea? Will this feature succeed?
On the surface level, this is certainly not one of those cases where one design is obviously better than the other. Rather, FB will just simply A/B test this feature and see which design yields a higher level of engagement. What’s interesting about this before and after is that the before had a more prominent display of how previous users had engaged with this story (i.e. the amount of likes and comments) and thus this would increase the probability of the current user wanting to get involved and like or comment. And in contrast, the new design is leaning more toward making the primary CTAs more prominent and more appealing-to-be-clicked instead of relying on the social pressure of the statistics of the story.
