Facebook’s new sponsored story ad unit is called ‘Comment’, closely reflecting the interface users are familiar with from the main Facebook page. It will consist of a display ad that poses a question beneath and invites users to give their opinion or participate in a conversation. If users leave a comment, it can become visible to their friends as both a Sponsored Story and as a news feed story.
The Comment Ad is the result of Facebook’s “Ad Expo” last year, which invited advertising agencies to submit ideas for advertising designs to engage consumers in new, interactive ways.
