ExpertRank only considers sources that possess subject-specific popularity among topic clusters and innumerable Web pages by experts commenting on the topic. The results include a handful of authoritative sources whose words on a subject constitute an expert answer. Ask.com, which still goes by its former name, Ask Jeeves, in the United Kingdom, does not specify who transforms the gathered knowledge into the actual answers to questions that appear on its website.

Ask.com was once a search engine in addition to a question-answer search engine. Ask.com abandoned the search industry in 2010. The Ask.com search engine also relied upon the ExpertRank algorithm to provide results to search queries.
