The Tinuiti Amazon Ads Benchmark Report is based on anonymized performance data from Amazon programs under Tinuiti management, with annual Amazon ad spend under management totaling over $400 million. Samples are restricted to those programs that have remained active and maintained a consistent strategy over the time periods studied. Unless otherwise noted, all figures are based on same-client growth. The trends and figures included are not meant to represent the official performance of Amazon advertising or the experiences of every Amazon advertiser.
