Amazon Retargeting: Re-Engage Shoppers Who Didn’t Buy
A shopper who viewed your product and left isn’t a lost cause — they’re your warmest prospect. Retargeting brings them back, and it’s the highest-ROAS advertising on Amazon.
Amazon retargeting re-reaches shoppers who engaged with your products but didn’t convert — the highest-ROAS advertising you can run, because the audience is already warm. On Amazon it’s done through Sponsored Display: views remarketing (people who viewed but didn’t buy) and purchases remarketing (past buyers). Start with a 14-day views campaign and custom creative.
01Why retargeting is the highest-ROAS play
Most shoppers don’t buy on the first visit — on Amazon it takes about 6–7 days on average from first interest to purchase. That gap is the opportunity. A shopper who viewed your product has already done the hard part: found you and shown interest. Reaching that warm shopper again during their consideration window converts at roughly 2–3× the rate of cold traffic, at a lower cost. That’s why retargeting consistently posts the best return on ad spend of any tactic — you’re not creating demand, you’re closing demand you already earned.
02Views remarketing — the core tactic
Views remarketing is Amazon’s primary retargeting tool, run through Sponsored Display audiences. It re-reaches shoppers who viewed your product pages but didn’t purchase, showing your ad to them on other detail pages, the Amazon homepage, and off Amazon. It offers two engagement types: “advertised products” (people who viewed your listing — your warmest, lowest-hanging fruit) and “similar to advertised products” (people who viewed comparable items — a softer, more prospecting-leaning group). Bid hardest on the advertised-products audience; it’s the closest to a sale. One quirk to know: negative targeting isn’t available for views remarketing, so you control it through lookback and bids.
03Choosing your lookback window
The lookback window — how far back Amazon looks for viewers — is your main lever, with options of 7, 14, 30, 60, or 90 days. A practical default is 14 days: recent enough to stay relevant, wide enough for volume. Push to 30+ days for considered-purchase categories where people research for weeks (supplements, electronics, home goods), and tighten toward 7 days if a longer window is dragging your ROAS down with stale viewers. Match the window to how long your category’s shoppers actually deliberate.
04Purchases remarketing — retention
Purchases remarketing flips retargeting toward existing customers, reaching past buyers over windows up to a year. Three plays: replenishment (remind buyers of a consumable to reorder), cross-sell (offer a complement — filters to someone who bought a coffee maker), and loyalty (bring buyers back for more of your range). It’s efficient because you’re reaching proven customers. The one rule: exclude the exact ASIN they already bought, unless it’s genuinely replenishable — otherwise you’re paying to advertise something they don’t need again yet.
05What good looks like
Rough benchmarks to judge your retargeting against:
| Tactic | Targets | Lookback | Typical ACoS |
|---|---|---|---|
| Views — advertised | Viewed your product, didn’t buy | 7–90d (start 14) | 12–22% |
| Views — similar | Viewed comparable products | 7–90d | Higher; more prospecting |
| Purchases remarketing | Past buyers (replenish / cross-sell) | up to 365d | 8–18% |
Views remarketing typically sees CTR around 0.4–0.8% and conversion rates of roughly 8–14% — strong numbers that reflect how warm the audience is.
06Setting up a retargeting campaign
The core flow is short:
- Create a Sponsored Display campaign and choose the product (a conversion-ready hero ASIN).
- Set targeting to Audiences → views remarketing, and pick your engagement types and lookback.
- Choose Dynamic bids — up and down, which suits retargeting because conversion likelihood is high.
- Add custom creative — logo, headline, and a real lifestyle image — rather than the default.
- Launch, and give it time before judging (more on that below).
07Retargeting best practices
A few things separate profitable retargeting from wasted spend. Custom creative matters — lifestyle images with a headline beat stock catalog images by roughly 25–40% on click-through. Structure over bidding — run separate campaigns per tactic and lookback so you can read and control each; one blurry “auto” campaign is the most common mistake. Be patient — views and purchases remarketing usually take 14–21 days to stabilize, so don’t cut a campaign in week one while the warm-shopper pipeline is still filling. And lean on Amazon’s out-of-stock awareness, which pauses ads automatically so you never retarget toward an unavailable product.
08Beyond Sponsored Display: DSP retargeting
Sponsored Display covers the essential retargeting tactics with minimal overhead. When you need more — custom-built audiences, sequenced messaging, larger off-Amazon reach, and finer frequency control — that’s the domain of Amazon DSP and its audience tools, which we reach later in the course. For most sellers, though, mastering Sponsored Display views and purchases remarketing captures the great majority of retargeting’s value. Next, we’ll optimize these Sponsored Display campaigns.
- Retargeting re-reaches warm shoppers who engaged but didn’t buy — the highest-ROAS tactic on Amazon.
- Views remarketing targets non-buying viewers; bid hardest on the “advertised products” audience.
- Start with a 14-day lookback; widen for considered categories, tighten if ROAS erodes.
- Purchases remarketing drives replenishment, cross-sell, and loyalty — exclude the owned ASIN.
- Use custom creative, separate campaigns per tactic, and give it 14–21 days before judging.
Frequently asked questions
What is Amazon retargeting?
It’s re-reaching shoppers who already engaged with your products — by viewing or buying — but didn’t convert on the action you want. On Amazon it’s done through Sponsored Display, and it’s the highest-ROAS advertising because the audience is already warm.
How does views remarketing work?
It targets shoppers who viewed your product pages (or similar products) within a lookback window but didn’t buy, then shows your ad to them on other detail pages, the homepage, and off Amazon. Re-reaching these warm shoppers converts at roughly 2 to 3 times cold traffic.
What lookback window should I use?
Start with 14 days for most products — recent enough to be relevant with enough volume. Extend to 30 days or more for considered purchases where shoppers research for weeks, and tighten toward 7 days if a longer window is dragging down your ROAS.
Is retargeting worth it on Amazon?
For most brand-registered sellers, yes — it’s often the highest-ROAS advertising available. Many accounts under-invest in it, paying peak search CPCs to convert shoppers who could return through a cheaper retargeting touch, which raises their whole account’s cost to convert.
What’s the difference between views and purchases remarketing?
Views remarketing targets shoppers who viewed but didn’t buy, aiming to close the sale. Purchases remarketing targets past buyers, aiming for replenishment, cross-sell, or loyalty. Views drives new conversions; purchases drives retention and repeat revenue.
