Abstract: Methods, systems, and apparatus, including computer-readable storage media for content group generation for a content delivery campaign. Content groups are generated from a resource identifier and a description. Digital content items are created for each content group, including digital content from the resource identifier and the description, as well as new digital content items. Candidate content groups are ranked according to request coverage gain and optionally one or more other ranking criteria. Request coverage gain is a measure of how much more request coverage is gained through keywords of one content group relative to the request coverage of one or more other content groups. By ranking according to request coverage gain, the selected candidate content groups are differentiated relative to one another, capturing potential content requests that would otherwise be missed by a campaign of content groups not selected based on request coverage gain.
