Amazon PPC is one of the most important growth channels for sellers and brands on Amazon. But many advertisers treat it as “pay more, get more traffic.” A profitable Amazon PPC strategy isn’t about spending the most. It’s about understanding how the system works. That’s exactly what we’ll walk through together.

What Is Amazon PPC and How Does It Actually Work?
Amazon PPC (pay-per-click) is Amazon’s advertising system where sellers and brands pay only when shoppers click their ads. Advertisers bid on keywords, products, or audiences, and Amazon uses a real-time auction to decide which ads appear, where they appear, and how much each click costs.
Ads can appear in search results, on product detail pages, in brand placements, across Amazon-owned properties, and on select external sites. Traditional advertising charges you for exposure. Amazon PPC is performance-based: no click, no cost.
How Amazon PPC Works: The 5-Step Process
- A shopper searches. For example, “wireless earbuds for running.” Amazon reads the search intent and finds relevant products.
- Amazon finds eligible ads. It checks every advertiser targeting that keyword, related keywords, competitor products, similar categories, or automatic matches.
- Amazon runs an ad auction. Each ad is scored on its bid, relevance, expected click-through rate (CTR), listing quality, and past performance. The highest bid doesn’t always win.
- Amazon picks the placement. Winning ads appear in Top of Search, Rest of Search, on product detail pages, or in other eligible spots.
- You pay when a shopper clicks. Impressions are free.
| Impressions | Clicks | CPC | Ad cost |
| 10,000 | 250 | $1.20 | 250 × $1.20 = $300 |
Where you run it: Campaigns are built in Campaign Manager. Third-party sellers get there through Seller Central, and first-party vendors through Vendor Central or the Amazon Ads console. You’ll need a Professional selling plan, because Individual plan sellers can’t advertise.
Why it matters: A new listing has no sales history, and Amazon’s organic ranking (often called A9/A10) rewards products that already sell. Ads create the first views, clicks, and orders that organic rank is built on. Competition for those spots keeps growing: Amazon’s ad revenue passed $68 billion across 2025, and advertising services grew 26% to $19.8 billion in Q2 2026.
Amazon Advertising Types Explained
| Ad Type | Brand Registry Required? | Purpose | Best Used For |
| Sponsored Products | No | Promote individual products (ASINs) | Driving sales from shopper searches |
| Sponsored Brands | Yes | Promote a brand and multiple products | Brand awareness and brand defense |
| Sponsored Display | Yes (for most sellers) | Reach audiences and retarget shoppers | Re-engaging past visitors, competitor conquesting |
| Amazon DSP | No (managed or self-serve minimums apply) | Full-funnel programmatic advertising | Large-scale brand growth |
Is Amazon PPC the Same as Sponsored Products?
No. Amazon PPC is the overall advertising model, and Sponsored Products is one ad format inside it. Most sellers start with Sponsored Products because these ads reach high-intent shoppers who are already searching for products like theirs.
- Sponsored Products: Each ad promotes one ASIN and looks like a regular listing. You don’t need Brand Registry. You can use auto campaigns, where Amazon picks targets, or manual campaigns, where you choose keywords and products.
- Sponsored Brands: These show your logo, a custom headline, and several products or a video at the top of search. They’re great for protecting your brand name from competitors. See our [Sponsored Brands guide — link when live].
- Sponsored Display: Targets audiences and products instead of search terms, so you can reach shoppers who viewed your listing but didn’t buy. Add it once your Sponsored Products campaigns are steady.
- Amazon DSP: Buys display and video ads automatically across Amazon and other websites. Most early-stage sellers don’t need it yet. See our [Amazon DSP guide — link when live].
- Also worth knowing, Sponsored TV: Streaming video ads on Prime Video, Twitch, and Fire TV, available self-serve with no minimum spend. Judge it by brand search growth, not last-click ACoS.
How Does the Amazon Sponsored Products Auction Work?
Short answer: The Sponsored Products auction is a real-time competition that runs every time a shopper searches. Amazon doesn’t simply reward the highest bid. It weighs bid, relevance, and predicted shopper engagement to decide which ads get seen. The winner pays a cost per click (CPC) that can’t go over their maximum bid.
📐 Diagram brief (for design): A horizontal flowchart: Search → Eligibility → Auction → Ranking → Click → CPC Charged. Below it, show Brand A ($2.00 bid, strong listing) winning a better position than Brand B ($2.80 bid, weak listing). On the final node, add a callout comparing Textbook second-price: pays just above the next bid with Alleged soft-reserve outcome: pays close to full bid.

Step 1: A Shopper Searches
A customer searches “stainless steel water bottle.” Amazon identifies relevant keywords, matching products, and active Sponsored Products campaigns.
Step 2: Eligible Advertisers Enter the Auction
| Targeting Method | How It Works | Example |
| Keyword targeting | You choose the search terms your ad should match | “stainless steel bottle” on exact match |
| Product targeting | You target specific competitor ASINs | A competitor’s water bottle listing |
| Automatic targeting | Amazon matches your ad using your product information, category, and customer behavior | Amazon finds relevant searches for you |
Step 3: Amazon Evaluates Each Ad
| Factor | What It Means | What Influences It |
| Bid | The most you’re willing to pay for one click | Bid amount, bid strategy, placement adjustments |
| Expected CTR | How likely shoppers are to click | Main image, price, reviews, rating, brand trust |
| Product relevance | How well your product matches the shopper’s intent | Title, bullets, backend keywords, category, past conversion performance |
Relevance example: For “running earbuds,” a listing built around running, workout, sweat-resistant, and sports earbuds beats a general headphone listing, even at the same bid.
Steps 4 and 5: Amazon Ranks the Ads and Charges on Click
Amazon doesn’t publish its full ranking formula. The working model most PPC pros use is Ad rank ≈ Bid × Expected CTR × Relevance. If your ad wins a spot and a shopper clicks it, you pay your CPC. If nobody clicks, you pay nothing.
| Advertiser | Bid | Listing Quality | Likely Outcome |
| Brand A | $2.00 | Excellent images, strong reviews, high relevance | Strong auction position |
| Brand B | $2.80 | Weak listing, lower CTR | May lose position despite the higher bid |
The 2026 Auction Controversy You Need to Know
On August 31, 2026, the FTC and 22 states sued Amazon over how its ad auction sets prices. The lawsuit covers Sponsored Products, Sponsored Brands, and Display ads. It says Amazon described its auction as second-price, where the winner pays just above the next bid. It also says that starting in 2019, Amazon added a hidden surcharge, internally called a “soft reserve price.” According to the FTC, Sponsored Products advertisers ended up paying their own full winning bid close to 80% of the time.
Amazon disagrees. It says Sponsored Products CPCs stayed flat after inflation from 2019 to 2024, that conversion rates rose 24% in that time, and that soft reserve prices are common across the industry. The case is ongoing, and nothing has been proven.
Our advice to every seller: set every bid as if you’ll pay that exact amount. Work backward from what a click is worth to you, using your break-even ACoS and conversion rate (covered below).
Which Amazon Bidding Strategy Should You Use?
| Strategy | What Amazon Does | When to Use It |
| Dynamic bids – down only | Lowers your bid when a click looks less likely to convert. Never raises it. | New campaigns without conversion history |
| Dynamic bids – up and down | Raises your bid up to 100% on top of search (up to 50% on other placements) when a click looks likely to convert, and lowers it when it doesn’t | Proven campaigns with steady conversion data |
| Fixed bids | Uses your exact bid every time | Testing new keywords with clean data |
You can also raise bids by placement (Top of Search, Rest of Search, Product Pages) by up to 900%.
Know your real maximum. These settings stack. A $1.00 bid with a 50% Top of Search adjustment and “up and down” bidding can cost up to $3.00 per click ($1.00 × 1.5 × 2). Given the FTC allegations, plan as if you’ll pay close to that ceiling.
Amazon PPC Match Types Explained
Short answer: Match types decide how closely a shopper’s search must match your keyword. Exact is the strictest, phrase is in the middle, and broad is the loosest.
| Match Type | What It Matches | Best Use | Risk Level |
| Exact | The keyword and close variants (plurals, misspellings) | Scaling proven converters | Low |
| Phrase | Searches containing the phrase in order | Controlled expansion | Medium |
| Broad | Searches with the words in any order, plus related terms | Discovering new search terms | High |
| Negative (exact/phrase) | Blocks your ad from matching those searches | Cutting wasted spend | N/A |
The 4 Auto-Campaign Targeting Groups
| Group | What It Targets |
| Close match | Searches closely related to your product |
| Loose match | Searches loosely related to your product |
| Substitutes | Shoppers viewing products that could replace yours |
| Complements | Shoppers viewing products that pair with yours |
Using one bid for all four groups is one of the most common mistakes we find in new accounts. Close match usually converts best. Give each group its own bid and review each one separately.
How Conversational and Voice Searches Change Match Types
In 2026, Amazon combined its Rufus assistant with Alexa+ to create Alexa for Shopping, which helps shoppers research, compare, track prices, and build carts. More than 300 million customers used Rufus in 2025. Alexa for Shopping rolled out to all U.S. customers starting May 13, 2026, including on Echo devices, so some searches are now spoken.
| Traditional Search | Conversational Search |
| running shoes | comfortable running shoes for beginners with knee support |
How to adapt: Use long-tail keywords, phrase match, and broad discovery campaigns to catch longer searches, and review negatives weekly. Improve your titles, bullets, A+ Content, and product details so Amazon understands who your product is for.
Which Amazon PPC Metrics Should You Track?
Short answer: The key Amazon PPC metrics are ACoS, TACoS, ROAS, CPC, CTR, and conversion rate. ACoS measures advertising efficiency. TACoS shows whether your ads are growing the whole business.
| Metric | Formula | What It Measures |
| ACoS | Ad spend ÷ Ad revenue | Advertising efficiency |
| TACoS | Ad spend ÷ Total revenue | How much the business depends on ads |
| ROAS | Ad revenue ÷ Ad spend | Revenue per advertising dollar |
| CPC | Ad spend ÷ Clicks | Average cost per click |
| CTR | Clicks ÷ Impressions | How attractive your ad is |
| CVR | Orders ÷ Clicks | How well your listing converts |
ACoS (Advertising Cost of Sales): Ad spend ÷ Ad revenue × 100. Example: $1,000 ÷ $4,000 = 25%
TACoS (Total Advertising Cost of Sales): Ad spend ÷ Total revenue × 100. Example: $1,000 ÷ $10,000 = 10%
Why TACoS Matters More for Brand Growth
| Ad Spend | Ad Sales | Organic Sales | Total Sales | ACoS | TACoS | |
| Month 1 | $3,000 | $10,000 | $5,000 | $15,000 | 30% | 20% |
| Month 3 | $3,600 | $12,000 | $15,000 | $27,000 | 30% | 13.3% |
Ad spend went up, but TACoS dropped from 20% to 13.3%. ACoS alone would say nothing changed. TACoS shows the business became less dependent on ads. For more, read our [TACoS vs. ACoS guide — link when live].
MBG Expert Take: “Most new sellers optimize for ACoS in isolation. That’s the wrong metric. TACoS tells you whether your ads are building organic rank or just renting visibility. It can rise during a planned growth push, but organic sales should grow with it. If TACoS keeps climbing while organic sales stay flat, the campaign structure needs a rebuild.” — [Name], MBG
📊 Case study: ACoS and TACoS in a real account

Caption: Seller Central Business Reports: June–August 2026 vs. the same period in 2025.
Year over year, total sales rose 20.8% and units rose 21%. The growth plan measured against a blended baseline of three earlier periods, which is why its figure (20.7%) is slightly different.
What this shows: ACoS and TACoS both went up, and that was the plan. We set a 30% ACoS ceiling to fund growth, and organic sales grew alongside paid instead of being replaced by it. The number we watched was ROAS: each extra ad dollar brought back less than before. So our next step was an efficiency audit, not a bigger budget.

Amazon PPC for Beginners: How Should You Structure Your First Campaigns?
Short answer: Combine automatic campaigns for keyword discovery with manual campaigns for control and scaling. The workflow is Discover → Harvest → Optimize → Scale.
- Launch automatic campaigns to find customer search terms, converting keywords, and competitor opportunities.
- Build manual keyword campaigns for the winners. Say your auto campaign finds “waterproof hiking backpack,” and it brings in 15 orders at a profitable ACoS. Move it into a Manual Exact campaign so you control the bid, and add it as a negative exact in the auto campaign so the two don’t compete.
- Add negative keywords to stop waste. Selling a luxury office chair and seeing “gaming chair repair” in your search terms? Add “repair” as a negative keyword.
| Campaign | Purpose | Targeting |
| 1. Auto Discovery | Keyword research | Close match, loose match, substitutes, complements (separate bids) |
| 2. Manual Exact | Scale proven keywords | High-converting terms plus a few high-intent keywords from your [Amazon keyword research — link when live] |
| 3. Manual Phrase/Broad | Find new opportunities | Keyword expansion and new search behavior |
Group products by keywords and margin. A $15 accessory and a $120 flagship product have very different break-even points, so they need separate campaigns and bids. Start at $10–$20 per day per campaign, and scale from what the data shows.
The #1 New-Seller Mistake
MBG Expert Take: “The #1 new-seller mistake is launching auto-only campaigns with no negative-keyword discipline.” — [Name], MBG
Build a starter list of negative keywords before you spend your first dollar. And don’t assume waste is only a beginner problem. In a September 2026 audit of the beauty and personal care account above, we found $1,045 a week going to 58 ASINs with zero attributed sales. Twenty-four pause actions freed up $775 a week to move to products already selling, without raising the budget.
The Amazon PPC Optimization Cycle
| Step | What to Do |
| 1. Analyze search term data | Review clicks, orders, CPC, ACoS, and conversion rate, at least every 14 days |
| 2. Harvest winners | Move converting terms into exact campaigns or dedicated campaigns, and raise their bids |
| 3. Control waste | Lower bids, pause targets, or add negatives on high-spend, low-converting, or irrelevant terms |
| 4. Scale profitable traffic | Increase budget, placement adjustments, and keyword coverage where results are proven |

How Much Does Amazon PPC Cost in 2026?
Short answer: Amazon PPC has no fixed monthly cost. You control the budget and pay only when shoppers click. Your CPC depends on category competition, keyword demand, listing quality, and how many advertisers you’re up against. For a deeper look, see our [Amazon PPC cost guide — link when live].
| Factor | Higher Cost | Lower Cost |
| Category | Crowded categories often cost more | Specialized or niche categories |
| Keyword | Broad terms like “running shoes” | Long-tail terms like “women’s waterproof trail running shoes size 8” |
| Listing conversion rate | Weak images, price, reviews, or content | Strong listings that convert well |
What clicks cost in one category: In an MBG-managed oral care brand on Amazon US, average CPC ranged from $1.20 to $1.34 in 2026, up 15–34% over the previous two years (source: the brand’s Amazon Ads console data). Treat this as one category’s reference point, not a market-wide average.
Monthly PPC budget = Target ad sales × Target ACoS
Example: $20,000 × 30% = $6,000 per month
Break-even ACoS = Profit before advertising ÷ Product price
Example: $15 ÷ $50 = 30%
Maximum profitable CPC = Break-even ACoS × Price × Conversion rate
Example: 30% × $50 × 10% = $1.50
How this works in a real account: For the 92-day plan above, we set ad spend from a 30% ACoS ceiling and an 11.05% TACoS target. Ad-attributed sales hit 99.1% of target on 96.6% of the budget, at a 29.2% ACoS.
Expect ACoS spikes, and don’t chase them. In the same account, ACoS jumped to 36.87% for about two weeks after a June deal event, as conversions dropped while CPCs stayed high. We held spend steady instead of raising bids, and ACoS came back down to about 28%.
What Changed in Amazon PPC in 2026?
- Creator content placements (August 10): Amazon extended Sponsored Products ads into creator content, including reviews, buying guides, and roundups from Amazon Influencer Program creators. Campaigns set to “Increase reach” were enrolled automatically. Top of Search and Product Page bid adjustments don’t apply off Amazon, but your CPC never goes over your max bid. Your next step: check the “Off Amazon” row in your placement report, and choose “Increase reach” or “Limit off-Amazon spend” for each campaign. (UK-only advertisers aren’t affected yet.)
- Alexa for Shopping ads (May onward): Amazon Ads lets advertisers appear in Alexa for Shopping through sponsored ads and Sponsored Products and Sponsored Brands prompts. Amazon reports that Sponsored Brands prompts drive a 6% increase in conversions. Check the Prompts report in the Ads console to see which questions trigger your products.
- The FTC auction lawsuit (August 31): covered above. Bid as if you’ll pay your full bid.
Is Amazon PPC Worth It?
Short answer: Yes, once your listing, pricing, inventory, and offer are ready. PPC can boost visibility and sales, but it can’t fix a weak listing or a product the market doesn’t want.
Before you increase your PPC investment, check that:
- ✓ Your product images are competitive, and you have at least 5 reviews and a 3.5★+ rating
- ✓ Your listing content matches shopper intent ([optimize your Amazon listing — link when live])
- ✓ Your pricing is competitive and you’ve won the Buy Box
- ✓ Your inventory will last through the campaign
Stock matters as much as the listing. Late in our 92-day plan, several fast-selling products were running low, with no restock until October. We pulled back ads on those products instead of burning through the stock. Sales per day dropped about 18%, but ACoS and TACoS stayed flat, and the inventory was saved for Q4. Total sales still grew 20.7% against a 25% target, and most of the gap came from that planned slowdown.
Common Amazon PPC Mistakes
| Mistake | The Problem | The Better Approach |
| Raising bids before fixing the listing | You pay more for clicks that don’t convert | Improve the main image, title, price, reviews, and content first |
| Optimizing only for ACoS | You miss whether organic sales are growing | Track ACoS, TACoS, organic sales, and ranking together |
| Running auto campaigns without negatives | Amazon spends on irrelevant searches | Review search term reports regularly and add negatives |
| Scaling ads into low stock | You sell out, then lose rank while the listing sits out of stock | Match ad pressure to days of inventory cover |
Frequently Asked Questions
What is Amazon PPC?
Amazon PPC is Amazon’s pay-per-click advertising model. Sellers bid on keywords, products, or audiences to show ads across Amazon and pay only when a shopper clicks.
How does the Amazon Sponsored Products auction work?
An auction runs every time a shopper searches. Amazon ranks eligible ads by bid, relevance, and expected engagement, and the winner pays a CPC that can’t exceed its maximum bid.
Does the highest Amazon PPC bid always win?
No. A highly relevant product with a strong listing can win a top spot while bidding less than a competitor.
What is the difference between ACoS and TACoS?
ACoS divides ad spend by ad-attributed sales, so it measures campaign efficiency. TACoS divides ad spend by total sales, including organic, so it shows whether ads are growing your whole business.
How much does Amazon PPC cost per click in 2026?
It depends on category and competition. In one MBG-managed oral care brand on Amazon US, average CPC ran $1.20–$1.34 in 2026. Plan your budget as target ad sales × target ACoS.
What is the difference between Sponsored Products and Sponsored Brands?
Sponsored Products promotes a single ASIN and doesn’t need Brand Registry. Sponsored Brands shows your logo, a headline, and several products or a video, and it does need Brand Registry.
Do I need Brand Registry to run Amazon PPC?
Not for Sponsored Products, but you do need a Professional selling plan. Sponsored Brands requires Brand Registry, and so does Sponsored Display for most sellers.
Should beginners start with automatic campaigns?
Yes. Pair an auto campaign for discovery with a manual exact campaign, and move proven search terms from auto to manual.
What is a good ACoS for Amazon PPC?
Any ACoS below your break-even ACoS, which equals your profit margin before advertising. Launch campaigns can run higher on purpose, as long as they have an end date and a TACoS target.
What changed in Amazon PPC in 2026?
Alexa for Shopping launched with Sponsored Products and Sponsored Brands prompts. Sponsored Products expanded into creator content on August 10. The FTC sued Amazon over its auction pricing on August 31.
The Bottom Line
Amazon PPC is an auction where listing quality and relevance matter as much as your bid. Start with Sponsored Products and an auto-to-manual structure, build your negatives before you spend, bid from your break-even math and your real maximum CPC, and measure success by whether organic sales grow with your ads. The goal isn’t more clicks. It’s the right clicks that create profitable sales.
