Before you launch a single campaign or spend a single dollar, you need to understand how Amazon advertising actually works. Amazon PPC is not like Google Ads, not like Facebook Ads, and not like anything you’ve used before.
Amazon’s entire system is built around commerce, not “traffic.” Every click, every search, every purchase feeds directly into your product’s organic ranking. If you don’t understand these foundations, you will make the wrong decisions from day one.
This article explains the core mechanics of Amazon PPC – the stuff you must know before you create your first campaign. No campaign setup here. No bid strategies. No complexity. Just the mental model that makes everything else make sense.
Everywhere this “sponsored” tag appears – you’re looking at a paid ad.
What Amazon PPC Actually Is
Amazon PPC is not about “buying visibility” the way social media ads work. On Amazon, shoppers are already looking for something specific. Your ads simply position your product directly in their path – at the top of search results, inside competitor listings, or on related product pages.
The critical part:
PPC clicks and PPC sales directly influence your organic ranking.
Which means:
- PPC doesn’t just get you sales – it builds your long-term organic visibility.
- A sale from a Sponsored Products ad counts the same as an organic sale for ranking.
- You literally “buy your way up” the search results by sending the right signals.
How Amazon Ranking Works (Completely Different From Google or Meta)
Google ranks pages using links, authority, and content. Facebook and Meta optimize for attention and engagement. Amazon works on a completely different system – Amazon ranks products based on how shoppers behave after they search for a keyword.
Here’s the core truth nobody on YouTube explains properly:
Amazon’s ranking engine is built on two things:
- CTR (Click-Through Rate) – do shoppers actually click your product when they search for a keyword?
- Keyword-linked sales – after clicking, do enough of those sessions eventually turn into purchases?
CTR comes first. It is Amazon’s strongest relevancy signal. If people don’t click, Amazon assumes your product is irrelevant and stops showing it. Zero clicks = zero data = zero chance to rank, no matter how good your conversion rate would be.
CVR (conversion rate) helps – but it does not drive ranking by itself. CVR only matters once CTR has already unlocked impressions and traffic. And because purchases on Amazon are delayed (many buyers save items, return later, buy after browsing), Amazon cannot rely on CVR as a real-time ranking input the way gurus claim.
Ranking comes from sales velocity on the keyword. Not “perfect CVR.” Not “guru-optimized funnels.” Just sales tied to the keyword shoppers typed in.
Amazon’s logic is brutally simple:
People search → they click → they buy → you rank.
More concretely:
- Shoppers search “leather duffle bag,” click your product, buy → you rank higher for “leather duffle bag.”
- Shoppers search “mens leather bag,” click you, buy → you rank higher for that term.
- Amazon does NOT care whether the sale came from PPC or organic – a sale is a sale, and every sale strengthens your position for that keyword.
When Amazon sees consistent keyword-linked sales, the system effectively says:
“This keyword reliably produces clicks and sales → increase organic visibility.”
Yes, CVR helps ranking – it supports the sales velocity loop – but it is not the king metric people pretend it is. If you spend $100k driving keyword-linked traffic with average CVR, you will rank because Amazon sees one thing only: sales velocity.
CTR drives the testing. Sales velocity drives the ranking. CVR is a secondary support metric – not the engine.
And that’s why PPC and organic ranking on Amazon are one system: PPC forces the exact search → click → sale loop Amazon uses to decide who deserves page one.
Note: Organic ranking is actually more complex than this overview suggests. It’s influenced by a mix of factors: how well your listing is written and indexed, your keyword alignment, your sales velocity (very important), your price positioning within the category, your reviews, your NCX rating and a few other signals. But ranking theory deserves its own deep dive – we’re not getting into all of that in this article.
The Core Ad Types (What They Are Conceptually)
There are several ad formats. For fundamentals, you only really need to understand where they sit.
Sponsored Products
The workhorse. This is where 90%+ of real PPC performance lives. All the important targeting methods (Auto, Keyword, Product, Category) sit here.
Sponsored Brands
Requires Brand Registry. Banner, store spotlight, and video placements. Good once you have a base, not required to understand the fundamentals.
Sponsored Display & Video
Useful in specific strategies, but not part of the conceptual first layer.
Sponsored TV
For big budgets and vague “awareness.” Not a beginner topic.
Targeting Types (Conceptual, Not Operational)
Within Sponsored Products, targeting tells Amazon how to match your product with shoppers.
Auto Targeting
Amazon chooses everything: keywords, related products, and category placements. Good for slow discovery, very poor for control.
Keyword Targeting
You choose which searches your ad can show up for. Three match types:
- Broad: Loose. Amazon can change word order, add words, and stretch meaning.
- Phrase: Your phrase stays intact, but words can appear before/after.
- Exact: Your keyword, mostly as-is. This sends the strongest signal to Amazon.
Product (ASIN) Targeting
Your ad appears directly on competitor product listings or related products.
Category Targeting
Your ad is shown across a full category. Wide, often wasteful if used too early.
Bids vs Budget (Gas Pedal vs Handbrake)
Two core controls in PPC that people constantly mix up:
- Bids = how aggressively you’re willing to pay per click. This is your gas pedal. It decides whether you even show up in the auction.
- Budget = how much you’re willing to burn through in a day. This is your handbrake. It caps the total damage.
Conceptually:
- You adjust bids to improve performance (more/less visibility for specific keywords/targets).
- You adjust budget to manage total spend across a day or campaign.
Beginners tend to over-fiddle with budgets when in reality, performance lives at the bid level.
The Metrics That Matter (With Actual Math)
Amazon throws a pile of metrics at you. Most of them are only useful once you have a baseline. These are the ones you must understand conceptually and mathematically.
ACOS (Advertising Cost of Sales)
Formula:
ACOS = Ad Spend ÷ Ad Revenue
Example:
- You spend $25 on ads
- Those ads generate $100 in sales
ACOS = 25 ÷ 100 = 0.25 = 25%
Lower ACOS = more ad-side profit. But if ACOS is “too low,” it usually means your bids are too weak and you’re missing ranking opportunities.
ROAS (Return on Ad Spend)
Formula:
ROAS = Ad Revenue ÷ Ad Spend
Using the same example:
- Ad Spend = $25
- Ad Revenue = $100
ROAS = 100 ÷ 25 = 4.0
So:
- ACOS = 0.25 (25%)
- ROAS = 4.0
And mathematically, using decimals:
ROAS = 1 ÷ ACOS
From here on, we will primarily refer to ROAS since it is easier for most people to understand – higher = better.
Conceptually:
- ACOS answers: “What % of my ad revenue did I spend on ads?”
- ROAS answers: “How many dollars do I get back for each $1 in ad spend?”
CTR (Click-Through Rate)
Formula:
CTR = Clicks ÷ Impressions
Example: 1000 impressions, 30 clicks → CTR = 3%
CTR is the primary relevancy signal for Amazon. It tells Amazon whether shoppers think your product matches what they searched for. High CTR = shoppers care. Low CTR = Amazon is wasting impressions on you.
This is a bit controversial: after testing thousands of campaigns, I’ve found that CTR matters far more than CVR early on. If shoppers don’t click you, Amazon throttles your impressions immediately – because no clicks means Amazon earns nothing from showing you.
Clicks create two signals simultaneously:
- You’re making Amazon money (Amazon loves this).
- You’re relevant for the keyword (Amazon rewards this).
No clicks = no visibility. CTR is what unlocks scaling.
CVR (Conversion Rate)
Formula:
CVR = Orders ÷ Clicks
CVR tells you how well your listing and product convert once shoppers land on your page. It’s still useful, but it is a secondary signal compared to click-through rate and, more importantly, sales velocity.
Amazon only cares about CVR indirectly, after CTR has proven people actually want to click you. A great CVR on low impressions does nothing. A decent CVR on high impressions helps you maintain sales velocity more efficiently. CVR is not shown anywhere in the Amazon PPC panels; you have to calculate it manually from orders and clicks.
CTR = relevancy. CVR = efficiency.
CTR tells Amazon whether you deserve to be tested. CVR tells you how many clicks you need to turn into a given number of sales.
In practice, sales velocity on specific keywords is what drives ranking. CVR doesn’t directly move you up the page – it just makes it easier (or harder) to generate the sales velocity Amazon actually rewards. CTR gets you tested, sales velocity gets you ranked, and CVR affects how expensive that journey is.
Orders & Revenue
These are your simple hard numbers: how many people bought and how much money those orders generated.
Other Factors That Influence CTR (and Therefore Ranking)
CTR isn’t happening in a vacuum. Several external factors heavily influence whether shoppers click your listing in the first place – and because CTR is the primary relevancy signal, these factors directly affect your ranking potential.
- Reviews & Review Count
Shoppers don’t “trust” a product until it has ~20 reviews. Below that, CTR is naturally suppressed because many users simply skip “unproven” products. More reviews → higher trust → higher CTR → higher ranking.
If you’re launching, use Vine (covered in the previous article) to accelerate review velocity. - Main Image Quality
Your main image is your #1 CTR driver. A poor main image kills CTR instantly. Clean lighting, tight cropping, high contrast, and clear subject matter dramatically improve clicks. - Price Positioning (Not Just “Low Price”)
Cheaper isn’t always better. Shoppers compare value, not price. If you’re too cheap, you look suspicious. If you’re overpriced, you look delusional. A strong value-to-price ratio drives CTR – and therefore impressions and ranking. - Relevancy of the Title
If your title doesn’t contain the keyword being advertised, CTR drops. Shoppers mentally scan titles for reassurance that they clicked the right product. - Category Correctness
If your product is miscategorized, Amazon will test it in irrelevant searches. Your CTR tanks. Your ranking tanks.
Correct category & browse node = relevant impressions = higher CTR = stronger ranking trajectory. - Star Rating
The difference between 4.0 ★ and 4.4 ★ is massive for CTR – shoppers bail instantly on low-star products. - Competitive Landscape
In saturated niches, perfect listings crowd you out. Stronger images, better value positioning, and early PPC help you break through.
The short version: CTR is the “click vote” that unlocks impressions and ranking. All of the above factors influence whether shoppers click you – and therefore how Amazon evaluates your relevance. The more trustworthy and visually compelling your product appears, the higher your CTR and ranking potential.
TaCoS vs ROAS (Why TaCoS Actually Matters)
ROAS (and ACOS) tell you how your ads perform in isolation. They do not tell you whether PPC is helping your overall business.
That’s where TaCoS comes in:
TaCoS = Total Ad Spend ÷ Total Revenue (organic + PPC)
Example: “Bad” ROAS, Good Outcome
Say you have:
- Ad Spend = $100
- Ad Sales = $150
ROAS = 150 ÷ 100 = 1.5 (weak)
On the surface, this looks terrible. But if those ads also lift your organic ranking:
- Organic Sales = $300
- Total Revenue = $450
Now TaCoS = 100 ÷ 450 = 22%
This is a win even with a weak ROAS.
- A campaign with ROAS 1.5 might still be a win if it boosts organic ranking and total revenue.
- A campaign with ROAS 2.5 is poor if the organic ranking doesn’t move.
This is why obsessing over ROAS alone is dumb. You care about the total sales picture, which TaCoS reflects.
Why You Must Not Adjust PPC Every Day
Amazon’s learning cycles take time. Every time you change bids too often, you’re kicking the legs out from under the learning process.
- New keywords and campaigns need several days (3–7) to normalize.
- Daily adjustments create noisy, useless data.
Reasonable cadence:
- 1× per week adjustment for small accounts.
- 2× per week max for larger accounts.
The only exception is during the first few days of a new campaign. If it burns your daily budget too fast, adjust bids down daily in 10–20% steps to bring it under control. And if you’re getting no impressions, you can increase the budget 10-20% daily until you start getting a decent amount of impressions and clicks.
Do not add new keywords to an existing campaign. If you want to test or launch a new keyword, create a new campaign for it. Amazon prioritizes keywords that already perform well, so anything new gets buried immediately. You won’t get a clean read, and Amazon won’t give it the impressions needed to prove itself.
Hot Tip – Why This Matters:
New keywords can’t compete with established winners inside the same campaign. They’ll get little to no visibility, which means bad data and misleading performance. A separate campaign gives each keyword a fair test and reliable results.
The Foundation You Need Before Launching Anything
At this stage, your job is to understand how the system behaves – not to go build a dozen campaigns.
- Amazon ranking is driven by sales on specific keywords.
- PPC sales count the same as organic sales for ranking.
- Sponsored Products is your main PPC playground.
- Targeting types define how tightly you match shopper searches.
- Bids control aggression; budgets just cap daily spend.
- ACOS and ROAS are two sides of the same coin.
- CTR is the primary relevancy signal. CVR is secondary.
- TaCoS matters more than ROAS because PPC and organic are joined at the hip.
- Do not adjust campaigns daily – let the data stabilize.
