Abstract: Systems and methods for identifying search results in response to a search query are presented. More particularly, images are selected as search results, at least in part, according to an attractiveness value associated with the images. Upon receiving a search query, a set of content is identified according to the query intent of the search query and includes at least one image. The identified set of content is ordered according an overall score determined according to relevance and, in the case of the at least one image, according to an attractiveness value. A search results generator selects items from the set of content according to their overall scores, including the at least one image, generates a search results page, and returns the search results page to the requesting party.
