Amazon’s advertising business is one of the most remarkable commercial transformations of the past decade. What started as a way for vendors to pay for better product placement is now approaching $47 billion in annual revenue, with operating margins that dwarf almost anything else in the advertising industry. If you work in marketing, understanding how Amazon did it is non-negotiable.

The Foundation: Access to Purchase Intent

Amazon’s advertising advantage starts with data. Amazon knows what consumers search for, browse, add to wishlists, buy, and how frequently — across more than 300 million active accounts globally, each generating rich, consented transaction history. Unlike social platforms that infer purchase intent from behavioural signals, Amazon observes it directly. This makes Amazon advertising structurally more efficient for lower-funnel objectives.

The Product Suite: From Sponsored Products to DSP

Amazon’s advertising stack has evolved from simple sponsored product listings to a full-funnel ecosystem: Sponsored Products (keyword-triggered, highest volume), Sponsored Brands (header banner placements for awareness), Sponsored Display (audience-targeted ads on and off Amazon), and Amazon DSP (reaching Amazon audiences across owned properties including Prime Video and third-party inventory).

Prime Video: The Next Chapter

Amazon’s most significant recent move is advertising on Prime Video, launched in early 2024 across major markets. With approximately 200 million subscribers globally, at CPM premiums justified by Amazon’s targeting capabilities and measurement infrastructure, this has the potential to add a new multi-billion revenue stream to an already formidable advertising business.

The Virtuous Cycle

What makes Amazon’s model sustainable is the reinforcing loop: advertising revenue funds lower prices and better logistics, which attract more shoppers, which generates more purchase data, which makes advertising more effective, which attracts more spend. Once this flywheel achieves sufficient momentum, it’s very hard to replicate. Every retailer building a media network today is attempting to construct a version of this flywheel. Understanding how Amazon built it is the first step toward understanding how to compete against it — or partner with it effectively.
