Retargeting on Amazon: DSP Strategies That Bring Shoppers Back

Pick any product listing on Amazon. On an average day, somewhere around 3% of visitors will actually buy. The other 97% leave — some will come back on their own, but most will not. Amazon DSP retargeting exists to change that math. It lets you serve ads to people who viewed your product, added it to cart, or browsed your category, and bring them back to convert.

We run DSP retargeting for brands across every major Amazon category at Skale. The patterns are remarkably consistent in terms of what works and what wastes money.

The Retargeting Audiences That Matter

Not all retargeting audiences are created equal. Here is how we segment them, ranked by typical ROAS:

Cart abandoners (7-day window): These shoppers were one click away from buying. Retargeting them within 7 days consistently delivers the highest ROAS of any DSP audience — we typically see 8-15x. The audience is small, but the intent is enormous.

Product page viewers (14-day window): Someone looked at your listing but did not add to cart. This is your largest retargeting pool and usually your highest volume. ROAS typically falls in the 4-8x range. Beyond 14 days, performance drops significantly as intent fades.

Category browsers who did not view your product: These shoppers browsed your category but never saw your listing. The intent is lower, so ROAS runs 2-4x, but this audience introduces your brand to relevant shoppers who might not have found you through search.

Past purchasers (for replenishable products): If you sell consumables — supplements, pet food, cleaning supplies — retargeting past buyers at the expected replenishment window is incredibly effective. Time it right and ROAS can exceed 10x.

Amazon DSP Retargeting Creative That Converts

The creative matters more than most brands realize. We have tested thousands of ad variations and the findings are clear:

• Product-on-white performs better than lifestyle imagery for retargeting. The shopper already knows your product — they saw the listing. Now you need recognition, not aspiration. A clean product image with a clear call-to-action converts best.
• Include the price if it is competitive. Retargeting ads that show price convert 20-30% better than those without, as long as the price is not a deterrent. If you are the premium option in your category, skip the price and lean on a benefit statement instead.
• Rotate creative every 2-3 weeks. Ad fatigue is real. The same banner shown 15 times becomes invisible. We maintain 3-4 creative variations per campaign and rotate based on performance data.
• Use responsive e-commerce ads (REA). Amazon dynamically generates these from your product listing. They auto-update with current pricing and reviews. They do not always outperform custom creative, but they are easy to launch and provide solid baseline performance.

Frequency Caps: The Most Overlooked Setting

Without frequency caps, DSP will show the same shopper your ad dozens of times. That is annoying and wasteful. We cap retargeting at 3-5 impressions per user per day for display and 2-3 per day for video. Higher frequency does not convert better — it just burns budget and irritates potential customers.

Budgeting and Performance Expectations

Retargeting should typically be 30-40% of your total DSP budget. The rest goes to prospecting and upper-funnel campaigns. Start with $5,000-$8,000/month in retargeting spend and scale based on your audience pool size and ROAS targets.

Expect the first 2-3 weeks to be a learning phase. DSP's algorithm needs data to optimize delivery. Do not make major changes during this window — let the campaigns stabilize before drawing conclusions.

At Skale, our Amazon DSP team builds retargeting into every DSP strategy from day one. It is the most reliably profitable segment of any DSP program, and it works because you are spending money on shoppers who already raised their hand. The brands that do Amazon DSP retargeting well recover a meaningful slice of that 97% — and the compounding effect on total Amazon revenue is substantial.
