Amazon DSP

Amazon DSP is Amazon's demand-side platform — the programmatic ad-buying system that lets advertisers place display, video and audio creatives across Amazon-owned inventory (Amazon.com, IMDb, Twitch, Fire TV, Kindle) and a wide network of third-party publishers, all targeted using Amazon's first-party shopper and purchase data.

Where Sponsored Products, Sponsored Brands and Sponsored Display live inside Seller/Vendor Central and bid into Amazon search and detail-page auctions, DSP is a separate console with its own targeting model, creative units and reporting. It is the upper-funnel companion to the keyword-driven Sponsored ads suite.

DSP vs Sponsored Display

The two products are easily confused — both serve display creatives — but their mechanics differ:

	Sponsored Display	Amazon DSP
Access	Self-serve in Ads Console	Self-serve console + managed-service option (often via agency)
Min spend	None	Historically $35k+/mo managed; self-serve has no hard floor but practical $5k+
Pricing	CPC	vCPM (viewable cost per thousand)
Targeting	Audiences, products, contextual	Full audience library + lookalikes + 3rd-party data + retargeting + custom segments
Inventory	Amazon detail pages, off-Amazon display	Amazon detail pages, Twitch, Fire TV, IMDb, IMDb TV, OTT, full open-web programmatic
Creative	Auto-generated product creatives	Custom display, video (OLV, OTT), audio
Goal	Direct response	Awareness, consideration, retargeting, video

The simplest mental model: Sponsored Display is the conversion-tilted slice of DSP, packaged for sellers without a media-buying team. DSP is the full programmatic stack.

Core audience categories

DSP's targeting power comes from Amazon's shopper data:

In-market — shoppers currently browsing a category (e.g. "in-market for running shoes").
Lifestyle — long-term behavioural segments ("fitness enthusiast", "new parent").
Remarketing — viewers/purchasers of your ASINs or competitor ASINs.
Lookalikes — modelled on your existing converters.
Advertiser audiences — your own CRM data uploaded via Amazon Marketing Cloud clean room.
Contextual — page-category targeting.

When DSP is the right tool

Retargeting at scale. Sponsored Display retargeting is capped to Amazon-domain users; DSP retargets across the open web.
Video and OTT. Streaming ads on Fire TV, Twitch, Prime Video — only available through DSP.
Pre-launch reach. Driving consideration for an ASIN before it has enough sales velocity to fuel Sponsored ads.
Brand defence against competitor conquesting. Layered DSP retargeting on competitor PDPs.
AMC-driven custom audiences. Building segments in AMC, activating via DSP.

When DSP is the wrong tool

Small accounts (<$50k/mo total ad spend). The min-effective-spend floor and operational overhead don't pay back.
Conversion-only goals on a single ASIN. Sponsored Products and Sponsored Display do this more efficiently.
No upper-funnel narrative. DSP without creative work or a defined audience strategy spends quickly and reports vaguely.

Measurement caveats

DSP reports clicks, impressions, view-through and click-through conversions across the whole attribution window — typically 14-day click + 14-day view-through. View-through conversions are real but easily over-credited; benchmark them against click-through ROAS, not summed.

Common mistakes

Buying DSP because the agency upsold it. If there's no audience strategy, the spend reports back as "brand awareness" with no measurable lift.
Comparing DSP ROAS to Sponsored Products ROAS. Different funnel positions, different attribution windows — the comparison is meaningless without AMC incrementality work.
Letting view-through conversions inflate the headline. Always show click-through and view-through ROAS separately.
Running DSP without retargeting exclusions. DSP will happily re-impression existing customers; build suppression segments for recent purchasers.
