Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. An indication is received from a content sponsor of a first collection of entities, sharing common characteristics, to be used for selection criteria for presenting a first content item. References to the first content item and selection criteria are stored. A query is received including terms/phrases associated with a first entity. It is determined that the first entity is included in the first collection of entities, wherein the terms/phrases do not include the first collection. Eligible content items are identified, each being associated with selection criteria including criteria specifying the first collection of entities. At least a portion of the first collection of entities is provided for presentation along with search results, including providing one or more of the eligible content items and the first content item. |
