Irvine-based Specific Media is reporting today that it has added a new tool focused on helping its client measure the impact of their brands. According to Specific Media, its new Brand Awareness Reports pulls data from Nielsen to measure the impact of campaigns, through such things as brand awareness, brand opinion, and the likelihood of online audiences to recommend the brand to others. The firm said the new service can be used to evaluate an advertising campaign's effectiveness "within weeks" of a campaign launch.
