A social networking system extends the reach of an ad by allowing an advertiser to seed a search for suggesting targeting criteria for an ad. Using the seeds, the social networking system identifies a set of seed objects from a social graph. The social networking system traverses the social graph to compute the similarity between the seed objects and candidate objects related to the seed objects. The social networking system then suggests to the advertiser a set of target objects based on the computed similarity. The social networking system receives a selection of target objects from the advertiser. And, using the selection, the social networking system determines one or more targeting criteria for the ad. Users with an edge to any of the selected target objects being eligible to receive the ad. |
