PPC captures existing demand, DSP creates and recaptures it. Start with PPC, because a shopper
already searching for your product is the cheapest customer you will ever get. Add DSP once
sponsored search is efficient and you have run out of intent to capture, not before.
The short version
- PPC first, always. Existing intent is cheaper than manufactured intent.
- DSP earns its place when you have exhausted search demand, or need retargeting at scale.
- DSP measurement is different. View-through effects mean shorter attribution misleads.
- Do not use DSP to fix a conversion problem. More traffic to a weak listing is worse.
- If neither is your bottleneck, neither is the answer.
The actual difference
I run Flapen with 50 operators managing about 70 brands, with an in-house technology
team building the advertising tools our operators use. Both formats are in scope for every
client, and the sequencing question comes up constantly.
| Sponsored ads (PPC) | Amazon DSP | |
|---|---|---|
| Demand | Captures existing search intent | Creates and recaptures demand |
| Placement | Search results and product pages | On and off Amazon, display and video |
| Targeting | Keywords and products | Audiences and behavior |
| Typical entry cost | Low, self-serve | Higher, often managed |
| Measurement | Click-attributed, fast | View-through matters, slower |
| Best at | Harvesting intent efficiently | Retargeting, awareness, competitive conquest |
| Risk | Bidding on terms that never convert | Paying to reach people who were never close |
The sequencing rule
Work through demand in order of how close the buyer already is.
First, capture the intent that exists. Someone typing your category into Amazon has
already decided to buy something. Sponsored Products against those terms is the cheapest
conversion available, and until that is efficient nothing further up the funnel makes sense.
Second, recapture the intent you nearly won. Shoppers who viewed your detail page and did
not buy are the strongest DSP audience there is, and retargeting them is usually where DSP
first pays for itself.
Third, create demand. Awareness audiences, competitive conquest, and in-market targeting.
Real, and the most expensive per outcome, so it belongs last.
Most sellers who try DSP early skip straight to the third rung and conclude DSP does not
work. What did not work was buying awareness before harvesting intent.
What has to be true before DSP
Five conditions. Miss any and DSP amplifies the problem rather than solving it.
- Sponsored search is efficient at the product's current stage, with a target that
reflects launch versus maturity rather than one number for everything. - Conversion rate is healthy. If your conversion rate is low, no amount of ad spend fixes
it, and DSP buys more traffic for a page that does not convert. - You know your true margin including returns, so an outcome can be judged.
- Inventory can absorb the volume. A stockout mid-campaign wastes the spend and the
ranking it bought. - You have somewhere for the traffic to land that suits a colder audience, which
usually means a Brand Store rather than a single detail page.
Measuring DSP honestly
The most common way DSP gets misjudged is measurement, in both directions.
Display advertising produces view-through effects, so a click-only attribution view will
understate it. Equally, generous view-through windows will overstate it by crediting
impressions to purchases that were always going to happen.
Two practical rules. Judge DSP over a longer window than sponsored ads, quarterly rather than
weekly. And hold total cost of customer acquisition as the primary number rather than any
in-platform metric, because the question is whether your blended acquisition cost improved,
not whether the DSP dashboard looks good.
What most agencies will not tell you
DSP is frequently sold as a maturity signal, the thing serious brands graduate to. Sometimes
that is true. Often it is an upsell into a format with higher minimums and softer
measurement, where underperformance is easier to explain away.
Ask two questions of any DSP proposal. What would make you tell me to stop, and what is the
smallest test that would prove this works. An honest answer to the second involves
retargeting your own detail page visitors before anything else, at a fraction of the budget
being proposed.
The other thing: DSP does not fix a listing, a price, or a return rate. It is a traffic
instrument, and traffic instruments amplify whatever the product page already does. If your
audit says conversion or pricing is the constraint, DSP makes the economics worse, not
better.
