A system that for determines keywords to be used in an online advertising campaign for a merchant is presented. During operation, the system sends a request on behalf of the merchant to a user, wherein the request asks the user to search for a product or service offered by the merchant. In response to the request, the system monitors keywords that are used by the user to search for the product or service. Next, the system receives from the user an indication that a subset of the keywords produced search results for the product or service or for a similar product or service. The system then presents to the merchant a report which includes the keywords that the user used to search for the product or service so that the merchant can use one or more of the keywords for the online advertising campaign.
