How Amazon PPC actually works in 2026: the auction, campaign types, match types, budgets and the mistakes that quietly waste spend. Written for sellers starting from zero.
PPC Fundamentals
Amazon PPC is a pay per click auction that runs inside Amazon’s search results and product pages. You bid on keywords or products, Amazon ranks the ads using your bid and how relevant your listing is, and you pay only when someone clicks. Get the structure right and it is the fastest lever you have for sales. Get it wrong and it quietly drains margin for months before anyone notices.
We manage $112M in ad spend across 200+ brands and 16 marketplaces. Almost every account we take on has the same problem: nobody explained the basics properly before the seller started spending. This guide is that explanation, no jargon, no filler, just how Amazon PPC actually works in 2026 and how to structure it so it makes you money instead of costing you it.

What Amazon PPC actually is
Amazon PPC (“pay per click”) is Amazon’s advertising system for Sponsored Products, Sponsored Brands and Sponsored Display. You choose keywords or products you want to target, set a bid, the most you’re willing to pay for a click, and set a daily budget. When a shopper searches or browses, Amazon runs a real time auction among everyone targeting that moment. Win, and your ad shows. Someone clicks, and you pay. Nobody clicks, and you pay nothing.
That last point matters more than people think. PPC is not a fee for visibility. It’s a fee for a genuine, measurable action. That’s what makes it different from most traditional advertising, and it’s why the numbers are so unforgiving: every pound you spend is traceable to a click, and (if you set it up properly) to a sale.
How the auction actually decides which ad wins
Amazon doesn’t just hand the top spot to whoever bids the most. The auction weighs three things together:
- Your bid, the maximum you’re prepared to pay for that click.
- Relevance, how well your listing (title, bullets, backend keywords, images) matches what was searched.
- Historical performance, click through rate and conversion rate on that keyword or placement, which Amazon uses as a proxy for “will this ad make Amazon money too.”
This is why a smaller brand with a tightly optimised listing and a high conversion rate can outrank a bigger competitor bidding twice as much. Amazon is optimising for its own revenue, not for your ad spend. A listing that converts well earns cheaper clicks over time, because Amazon would rather show shoppers ads that lead to a sale.
The three campaign types, and when to use each
Sponsored Products
The workhorse. Your product appears in search results and on competitor listings, styled to look like an organic result. Start here. It’s the highest intent placement on Amazon, because the shopper has already typed exactly what they want.
Sponsored Brands
A banner at the top of search results showing your logo, a headline and up to three products. Requires a registered brand. Use it once you have Sponsored Products data telling you which keywords convert. Sponsored Brands works best defending or attacking terms you already know matter.
Sponsored Display
Retargets shoppers who viewed your listing (or a competitor’s) but didn’t buy, both on and off Amazon. Lower intent than the other two, but cheap and effective for closing the loop on people who were already close to converting.
Once a brand has proven profitability across all three, the next step up is programmatic display through Amazon DSP, we cover exactly what that adds, and who’s actually ready for it, in Amazon DSP explained, for sellers who have outgrown Sponsored Products.
Match types and negative keywords: where budgets actually leak
Every keyword you target has a match type, and this is the single most misunderstood setting in Amazon PPC:
- Broad match, triggers on searches related to your keyword, including synonyms and loosely connected terms. Widest reach, most wasted spend if left unmanaged.
- Phrase match, triggers when the search contains your keyword phrase in order, with extra words allowed either side. A reasonable middle ground.
- Exact match, triggers only on the exact keyword (or very close variants). Narrowest reach, highest intent, usually the cheapest clicks once you know a term converts.
The mistake we see constantly: broad match left running with no negative keywords for months. Negative keywords tell Amazon “don’t show my ad for this search.” Without them, broad match will happily spend your budget on searches only loosely related to what you sell. A weekly search term report review, moving winners to exact match and blocking losers as negatives, is the single highest leverage habit in PPC management.

Automatic vs manual targeting
Automatic campaigns let Amazon choose what to target based on your listing content, genuinely useful for discovering keywords you hadn’t thought of, and for brand new listings with no data yet. Manual campaigns let you choose the exact keywords or ASINs to target. The right approach for almost every brand: run both, use automatic campaigns as a keyword research engine, then graduate the winners into tightly controlled manual campaigns.
Automatic campaigns actually split into four targeting groups Amazon runs behind the scenes: close match, loose match, substitutes and complements. You can’t bid on these individually, but you can see which one is driving results in your search term report. If “complements” is spending heavily with poor conversion, that’s a sign your ad is showing next to genuinely unrelated products and needs tighter negatives.
Bid strategies and placement: the part most sellers never touch
Every campaign has a bid strategy setting, and it’s usually left on the default without a second thought. There are three options:
- Dynamic bids, down only. Amazon lowers your bid in real time when a click looks less likely to convert. The safest default, and the right choice while you’re still gathering data.
- Dynamic bids, up and down. Amazon can raise your bid by up to 100% for top of search placements it judges highly likely to convert, and lower it elsewhere. More aggressive, more reach, but it can push your ACOS up fast if the listing itself isn’t converting well.
- Fixed bids. Amazon never adjusts. You control it entirely, useful once you know exactly how a keyword performs and want predictable spend.
On top of the base bid, you can also add placement modifiers, extra percentage bid increases specifically for “top of search” or “product pages” placements. This is where a lot of budget disappears unnoticed: a 50% top of search modifier on a broad, poorly negated campaign will burn through a daily budget by mid morning. Set modifiers deliberately, on campaigns you already trust, not as a blanket setting across the account.
The metrics that actually matter
ACOS (Advertising Cost of Sale) tells you what percentage of ad attributed revenue you spent on ads. TACOS (Total Advertising Cost of Sale) tells you what percentage of all revenue, ad driven and organic, went on ads. They answer different questions, and confusing them is how sellers end up cutting the wrong campaigns. We’ve written the full breakdown, with our own account benchmarks, in ACOS vs TACOS: which number actually runs your business.
A campaign with a “bad” 35% ACOS can still be the healthiest thing in your account, if it’s the one ranking a brand new listing that has zero organic sales to fall back on yet.
Where most beginners go wrong
- Running broad match with no negatives. The single biggest source of wasted spend we find in new accounts.
- Judging a campaign in week one. Amazon’s algorithm needs data, most campaigns need 2 to 4 weeks of consistent spend before the numbers mean anything.
- Chasing ACOS to zero. An ACOS of 0% usually means a budget so small it isn’t ranking anything. Profitable is not the same as minimal.
- One giant campaign for everything. Impossible to control bids sensibly when your best and worst keywords share a budget.
- Ignoring the listing. PPC can’t fix a page that doesn’t convert, see why your A+ content is not converting before you blame the ads.
A simple structure to start with
Three campaigns, per product or tight product group, is enough to start: one automatic (discovery), one broad/phrase (research, heavily negated), one exact match (your proven, highest value keywords). Review search terms weekly. Promote winners up, negate losers down. Resist the urge to add more campaigns before this loop is running properly. Complexity without a process just makes the account harder to diagnose when something goes wrong.
Reading a search term report without wasting an afternoon
The search term report shows the exact words shoppers typed before your ad appeared. It’s the single most useful document in the account, and most sellers only glance at it. Every week, sort the search term report by spend and ask three questions of each row. Has this term spent more than one product’s worth of profit with zero sales? Negate it. Has it converted more than once at a healthy ACOS? Move it into its own exact match campaign with a bid you control precisely. Is it a near miss, relevant but not quite what you sell? Negate it too, before it eats budget that belongs to terms that actually convert. Do this weekly and the account gets measurably cheaper every month, because you’re constantly redirecting spend away from noise and toward what’s proven.
DIY, or bring in an agency?
Plenty of sellers run PPC themselves successfully, especially at low spend levels where the time cost of learning is worth it. The maths changes once your ad spend is large enough that a percentage point of ACOS is real money, or once you simply don’t have the hours to review search terms every week. Reviewing them weekly, properly, is not optional if you want the account to improve. We’ve laid out the honest cost, speed and risk comparison, including where DIY genuinely wins, in Amazon PPC agency vs in house: the complete breakdown, and what an agency should actually cost you in what does an Amazon PPC agency cost in 2026. If you do bring in help, ask exactly how they price. Percentage of spend fee structures quietly reward an agency for spending more of your money, not for lowering your ACOS. We publish our pricing for exactly that reason.

Frequently asked questions
There’s no single “good” number, it depends on your margin and your goal. A new listing trying to rank often runs a deliberately higher ACOS (25 to 40%) because the objective is sales velocity, not short term profit. Once a listing is established, most healthy accounts settle into the teens to low twenties. Our own book averages 17.84% lifetime ACOS across very different categories, which is a useful reference point, not a target to copy blindly. See what is a good ACOS on Amazon for benchmarks by category.
Enough to get statistically meaningful data within a few weeks. For most categories that’s at least £15 to £30 a day per core product while campaigns are learning. Less than that and you’ll be waiting months for enough clicks to draw any real conclusions.
Sponsored Products, every time. It’s the highest intent placement and, critically, it’s how you generate the keyword and conversion data that makes Sponsored Brands worth running later.
Yes, and plenty of sellers do it well, especially early on, when the time investment of learning is small relative to spend. It gets harder to justify as spend grows or as your time becomes worth more elsewhere. We break down the real trade offs, not just the sales pitch, in agency vs in house.
Expect 2 to 4 weeks before campaigns have enough data to optimise properly, and 8 to 12 weeks before performance stabilises into a reliable pattern. Anyone promising results in days is either exaggerating or bidding recklessly high to force it.
Indirectly, yes. Sales velocity from PPC feeds Amazon’s organic ranking signals. It’s not a direct “spend more, rank higher” mechanism, but a well run campaign absolutely helps organic rank move. We walk through exactly how, including a real 15→3 ranking case, in our Amazon SEO guide.
Dynamic “down only” lets Amazon reduce your bid when a click looks unlikely to convert, and is the safest setting while you’re gathering data. Dynamic “up and down” lets Amazon raise your bid by up to 100% for top of search placements it rates highly, which can drive more sales but also push ACOS up if the listing isn’t converting well. Fixed bids give you full control with no automatic adjustment, best once you know how a keyword actually performs.
