Abstract:
An advertising campaign maintained by an online system includes an objective, and the online system determines a metric for the advertising campaign based the objective. For example, the online system determines the metric as a ratio of an amount received from an advertiser for presenting the advertising campaign to a number of completed objectives associated with the advertising campaign. Additional advertising campaigns including the objective are identified, and the online system determines metrics for the additional advertising campaigns. The online system compares the metric for the advertising campaign to the metrics for the additional advertising campaign and communicates information to the advertiser based on the comparison.
