What Amazon's long-term sales metric can and cannot prove
Seb Joseph examines Amazon's attempt to measure advertising value beyond its usual attribution window. Its long-term sales metric uses early shopper actions and historical 12-month returns to project future sales. Agency responses in the article show why advertisers should compare that projection with observed sales and why access to enough underlying data matters. Read it when a projected long-term value is being used to justify retail media investment. Amazon's estimate that roughly one fifth of brand value appears after the standard window is its own analysis, not proof of incremental sales.
