CMO insights help advertisers optimize campaign tactics and maximize media ROI. CMOs offer a holistic marketing strategy that includes a unified view on your campaigns. Advertisers can measure and compare the impact of strategies and tactics for the top, middle and bottom of a funnel. CMO's online article-level reports show the relationship between audiences and locations in terms of results. CMOs are able to provide agility in order to optimize and drive the effectiveness of campaigns. Omnichannel Statistics (OCM), a tool that allows advertisers to measure the total impact of their campaigns on Amazon and other sites, while the campaign is still in its middle period of advertising, is a way for them to do so. CMOs incorporate insights from all channels, including Amazon and off Amazon as well as online shopping and offline activities. All Amazon Ads offer privacy and security. All reports are anonymized and aggregated.
