AUTOMATIC ADVERTISING CAMPAIGN STRUCTURE SUGGESTION

A group of key terms associated with an ad campaign are identified, each key term including a keyword or a key phrase, the ad campaign being associated with one or more negative key terms. The group is automatically classified into two or more sub-groups each having one or more key terms, at least one of the sub-groups having key terms that have a higher similarity level than the key terms in the original group. Associations between the one or more negative key terms and the two or more sub-groups are determined, and the two or more sub-groups of key terms and associated zero or more negative key terms are provided to a sponsor of the ad campaign.
