An advertiser is focused primarily on direct response, as opposed to branding. The advertiser should delete keywords from a search campaign if the keywords:
generate many clicks and conversions
generate many impressions and very few conversions
contain more than two words in the phrase
contain words that are duplicated in a display campaign
