Someone in almost every marketing meeting I’ve sat in eventually says “we should look into Amazon DSP.” Then the conversation moves on. Nobody explains what it is. Everyone nods like they already know. I did this too, for longer than I’d like to admit, before I actually had to run one of these accounts myself.
So let’s just get into it.
Amazon DSP stands for Demand-Side Platform. It’s how Amazon lets advertisers buy display, video, and audio ads programmatically — which is a fancy way of saying the buying happens through an automated auction instead of a person calling up a website and negotiating a rate, the way ad buying used to work.
“Demand side” refers to who’s using it. You. The advertiser. You’re the one demanding ad space. On the other end are publishers offering up that space. Amazon DSP sits in between and matches your budget and targeting to available inventory, usually in well under a second per decision.
And here’s the bit that confuses almost everyone I explain this to: you don’t have to sell a single product on Amazon to use it. I’ve had clients ask me three or four times before it actually sinks in. Brands with zero Amazon storefront run DSP campaigns constantly, just to tap into Amazon’s audience data across the wider web — IMDb, Twitch, Fire TV, and a long list of third-party sites and apps that pull inventory through Amazon’s ad exchange.
Amazon DSP vs. Sponsored Ads (these are not the same thing)

I get this mixed up question constantly, so let me separate it cleanly, because I’ve seen agencies bill clients for “DSP work” that was actually just Sponsored Products management. Not the same product. Not even close.
Sponsored Ads — Sponsored Products, Sponsored Brands, Sponsored Display — are keyword driven and self-serve. Someone types “running shoes” into the search bar. You bid on that keyword, your ad shows, you pay when they click. That’s bottom-funnel stuff. The person already has their wallet out, more or less.
DSP works further upstream. There’s no keyword trigger. It’s audience driven. Instead of waiting for someone to search, you’re identifying people who look like your buyers, based on browsing behavior, past purchases, or similarity to your existing customer base, and getting in front of them before they’ve started shopping at all.
I usually describe it to clients like this: Sponsored Ads is fishing where the fish are already biting. DSP is figuring out where the fish are probably going to swim to next, and getting there first.
What you can actually do with it
A few things make the learning curve worth it, in my experience.
Amazon has first-party purchase data that basically nobody else has. Not modeled guesses about what someone might like — actual transaction history. That’s the real edge over a generic third-party DSP.
You can also run ads well outside Amazon.com itself. Prime Video, Twitch, plus a big footprint of third-party publisher inventory through Amazon’s partnerships.
Formats-wise you get display, video, and audio, across desktop, mobile, and connected TV.
And you can build full-funnel campaigns — pure awareness, mid-funnel consideration, bottom-funnel retargeting — all inside one platform, using the same underlying audience data the whole way through.
Last year I ran a campaign for a home goods brand that wasn’t sold on Amazon at all. Purely retargeting and lookalike audiences based on category browsing. It beat our Meta retargeting on cost-per-click, not by a small margin either, mostly because the audience data Amazon has is just more accurate than modeled interest targeting from other platforms. I wasn’t expecting that going in, honestly.
Self-service or managed — pick carefully
This is where I’ve seen smaller brands get burned.
Self-service means you or your team run the platform yourselves. No management fee. Full control over targeting and bids. But there’s a real learning curve, and a bad targeting setup or a rushed bid strategy can chew through budget fast. I’ve watched it happen.
Managed service means Amazon’s team runs campaigns on your behalf. Historically this has come with a minimum monthly spend commitment in the tens of thousands of dollars, which rules it out for most small and mid-sized businesses right away.
If you don’t have someone in-house who’s actually run programmatic before, self-service through an approved agency partner is usually the more realistic starting point rather than going direct with Amazon.
Is it actually worth it?
Depends what you’re trying to get out of it, honestly, and I won’t pretend otherwise.
It’s strong if you want reach combined with genuinely reliable audience data — particularly if you already sell on Amazon and want to connect upper-funnel awareness to actual purchases happening on the platform. It’s a harder sell if you’re a small brand on a tight budget without anyone who understands programmatic buying already. The setup time and learning curve can eat into your returns before you find your footing.
My honest advice: test with a modest budget first. Don’t commit serious spend on day one. Programmatic rewards iteration, not a single big bet.
Questions I get asked a lot
Do I need to sell on Amazon to use Amazon DSP? No. It’s open to advertisers whether or not you have a storefront there.
What does it cost? Self-service has no management fee — you’re paying for media itself, usually through auction-based CPMs. Managed service historically requires a much bigger monthly commitment, and that varies by market.
How is it different from Sponsored Ads? Sponsored Ads are keyword-triggered and self-serve, aimed at people already searching. DSP is audience-triggered and programmatic, aimed at reaching people based on behavior signals, often before they’ve started actively shopping.
Can I run connected TV ads through it? Yes. Video placements extend into CTV inventory, including Amazon-owned platforms like Prime Video and Fire TV, plus third-party streaming inventory available through Amazon’s exchange.
