What Is Amazon DSP? The Complete Guide to Retargeting and Growth

If your entire Amazon advertising strategy consists of Sponsored Products campaigns, you are only reaching shoppers who are already actively searching for your product right now. Amazon DSP (Demand Side Platform) reaches everyone else — shoppers who viewed your product and left, shoppers browsing competitor products, and entirely new audiences who haven't discovered your brand yet.

Amazon DSP is the programmatic advertising platform that lets brands buy display, video, and audio ads both on and off Amazon — using Amazon's unmatched first-party shopper data as the targeting signal. According to Amazon Advertising, brands using DSP alongside Sponsored Products see 30-40% higher total sales lift than those using Sponsored Products alone.

DSP vs. Sponsored Display: What's the Difference?

Both offer retargeting, but the differences are significant:

• Access: Sponsored Display is available to all sellers. DSP requires agency access or $50,000+/month minimum with Amazon Managed Service.
• Inventory: Sponsored Display runs mostly on Amazon. DSP runs on premium publishers — Twitch, IMDb, Fire TV, CNN, and thousands more.
• Creative: Sponsored Display uses auto-generated creatives. DSP supports custom video, HTML5, and audio ads.
• Bidding: Sponsored Display is CPC. DSP is CPM (cost per thousand impressions).
• Audiences: DSP offers Amazon Marketing Cloud (AMC) custom audiences not available in Sponsored Display.

The Four DSP Funnel Stages

1. Awareness — Reach New Audiences

Target "In-Market" shoppers actively browsing your category who haven't discovered your brand. Use Streaming TV (STV) and Fire TV for video ads that build brand recognition at scale.

2. Consideration — Intercept Competitor Shoppers

Target shoppers who are actively viewing competitor ASINs. Show them your product at the exact moment they're considering an alternative. This is one of the highest-ROI targeting strategies available in the DSP ecosystem.

3. Retargeting — Convert Interested Shoppers

Target shoppers who viewed your product in the last 30 days but didn't purchase. These are high-intent audiences — they've already expressed interest. Retargeting them consistently delivers 3-5x ROAS compared to cold audience campaigns. This complements your Sponsored Products strategy by capturing the shoppers PPC can't re-engage.

4. Loyalty — Grow Customer Lifetime Value

Target past purchasers with complementary product ads. If they bought your shampoo 60 days ago, show them your conditioner. This drives repeat purchase rates and Customer Lifetime Value — two metrics that compound significantly over time for managed brand accounts.
