In one embodiment, a method includes accessing a data set comprising a list of objects matching a query, a pre-determined static-rank for each object calculated based on a static-scoring algorithm, and a final-rank for each object calculated based on a final-scoring algorithm, and revising the static-scoring algorithm based on a comparison of the static-ranks and the final-ranks of each object listed in the data set, where the static-scoring algorithm is revised in order to reduce a difference between the static-ranks and final-ranks of the objects listed in the data set.
