What is DSP?
Demand-Side Platform
Quick Answer
DSP stands for Demand-Side Platform. It is a technology platform that allows advertisers to automatically buy ad placements across thousands of websites, apps, and streaming services through real-time bidding (RTB). The most well-known DSPs include Amazon DSP, Google DV360, and The Trade Desk. DSPs enable precise audience targeting, retargeting, and full-funnel advertising at scale.
In Detail
Understanding DSP
A Demand-Side Platform automates the process of buying digital advertising across the open web and apps. Instead of negotiating individually with each website or publisher, advertisers use a DSP to bid on ad impressions in real time — the entire process happens in milliseconds as a webpage loads. The "demand side" refers to the advertiser side of the marketplace (supply side being the publishers).
Amazon DSP is particularly significant for eCommerce brands because it combines programmatic buying capability with Amazon's massive first-party shopping data. You can target audiences based on actual purchase behavior, browsing history, and product interests — data that no other DSP can match. This makes Amazon DSP uniquely powerful for retargeting shoppers who viewed your products, conquesting competitor audiences, and building awareness among in-market shoppers.
DSP campaigns serve display banners, video ads, and OTT (Over-The-Top) streaming ads across Amazon-owned properties (IMDb, Twitch, Fire TV, Amazon.in) and third-party websites through Amazon Publisher Services. This means you can reach Amazon shoppers even when they are browsing news sites, watching videos, or using mobile apps.
The key advantage of DSP over traditional self-service ads is audience-based buying vs. keyword-based buying. Instead of targeting "running shoes" as a keyword, you can target "people who browsed running shoes in the last 30 days but did not purchase" — a fundamentally different and more precise approach to advertising.
Business Impact
Why DSP Matters for Your Business
For brands selling on Amazon, DSP completes the full-funnel advertising strategy. Sponsored Ads capture high-intent shoppers at the bottom of the funnel. DSP builds awareness at the top, nurtures consideration in the middle, and retargets abandoners who almost converted. Together, they drive significantly more total sales than either alone.
DSP is also essential for brands competing in categories where Sponsored Ads alone cannot drive enough volume. If you have maxed out your Sponsored Ads budget efficiently, DSP is the next lever for incremental growth — reaching new audiences who have not yet searched for your product category.
