In one embodiment, a method includes receiving an indication that a first user has interacted with a first object within a newsfeed of an online social network, the first object including one or more n-grams, and identifying a list of second objects from one or more data stores, each second object matching one or more of the n-grams from the first object and being identified based at least in part on a predetermined static-rank of the second object. The method also includes calculating a final-rank for each of the identified second objects and determining one or more revised static-ranks for one or more of the identified second objects based on a comparison of the final-ranks and the static-ranks of the identified second objects.
