1. One or more hardware devices having computer-usable instructions embodied thereon that, when executed by one or more computing devices, perform a method for presenting ranked search results to a user such that a spam domain is prevented from being presented with an undeservedly high rank within the presented ranked search results, the method comprising: receiving a list of one or more contributing domains associated with a domain; determining a maturity for at least one of the one or more contributing domains, wherein determining the maturity for at least one of the one or more contributing domains comprises identifying at least one of the one or more contributing domains as an immature domain calculating a rank for the domain based at least in part on the maturity for the at least one of the one or more contributing domains, wherein calculating the rank for the domain comprises calculating the rank based at least in part on a rank of the immature domain, wherein the rank of the immature domain is based on contributing domains associated with the immature domain that have been identified as mature domains; and generating a search results user interface comprising search results including the domain, wherein the domain is ordered in the search results according to the calculated rank for the domain.
