A new Facebook Ad targeting feature now allows advertisers to target those who have recently interacted with Facebook. The targeting type “Action Spec” allows users to target by the recency of specific actions taken. This recency targeting is currently in beta mode.
The new “Action Spec” targeting allows users to target by the recency of specific actions taken. This will allow local advertisers to target those users who recently checked into their shop over the weekend, or an artist to target someone who recently listed to music on Facebook this week. This would be an ideal metric for those advertisers that have more complex conversions. You cannot, however, target the “like” of a Facebook page (unless you have admin access).
According to InsideFacebook, advertisers can target users who have performed the action in a range of 14 day (default) or under. This current targeting is only available to Preferred Marketing Developers with the Ads API.
