Amazon Attribution is a free, self-service advertising and analytics measurement solution that provides marketers with insight into how their non-Amazon marketing channels perform on Amazon. It allows brand-registered sellers to evaluate the effectiveness of their external advertising campaigns and provides detailed analytics and insights to help them determine which non-Amazon marketing channels are most effective for their business. Amazon Attribution measures non-Amazon Ads media such as search ads, social ads, display ads, video ads, and email marketing. It uses parameterized URLs to track metrics such as click-throughs, impressions, detailed page views, purchase rate, add to cart, and total sales. With Amazon Attribution, advertisers can understand how users interact with their store and the broader Amazon ecosystem, optimize their existing campaigns to drive more users that convert, and improve their ROI. Amazon Attribution is currently available for professional sellers enrolled in Amazon Brand Registry, vendors, KDP authors, and agencies with clients who sell products on Amazon. It is available in nearly a dozen countries, including the US, Canada, and Mexico in North America.
