Amazon DSP

Amazon DSP is a wildly aggressive, hyper-growth leviathan that completely attacked the market using the most powerful data on Earth: "Actual Purchase Intent." Google knows what you search; Facebook knows who you like; Amazon mathematically knows exactly what you *buy*. Amazon DSP is the absolute mathematical weapon of choice for brands that want to target users based on their exact, historical credit-card transaction data. Its absolute biggest differentiator is "Amazon First-Party Purchase Data." A diaper brand wants to target new parents. In Google, they target people who searched "baby clothes." In Amazon DSP, they mathematically target people who physically bought a crib on Amazon.com 3 weeks ago. Amazon DSP uses this terrifyingly accurate mathematical data to buy ads *off* Amazon (on the open internet) and drive the user back to the Amazon product page to execute the sale. Because it targets retail execution, its "Closed-Loop ROI Measurement" is unparalleled. A user sees an ad on a random blog via Amazon DSP. Three days later, they go to Amazon.com and buy the product. Because Amazon controls the DSP and the store, it mathematically links the two events with 100% certainty. It provides the advertiser with a flawless, mathematically indisputable "Return on Ad Spend (ROAS)" metric, completely destroying the ambiguity of standard ad attribution.
