Part A: Introduction to Amazon Sponsored Products

Why should I use Amazon Sponsored Products?

Amazon’s PPC ads are second to none for product promotion. They’re even becoming a contender for Google search’s PPC market domination overall. 

A solid Amazon PPC Strategy is – dare we say – necessary to your success on Amazon. For a good reason, the adoption rate is sky-high: Most merchants use Amazon PPC to promote their products. 

And of those, almost three-quarters use Sponsored Products exclusively. Why? 

1. To get visibility

If you want to occupy the top of search, you have to. There is little organic space above the fold.

If you don’t bid on those coveted ad spaces, your competitor will. 

As long as ads continue not to hurt user experience, you can be sure that the landscape will continue to grow in real estate and complexity, which is all the more reason to get on board. 

2. Because they work! 

Amazon Sponsored Products are super-effective. It’s hard to imagine an advertising opportunity that is lower-funnel or more tightly tied to making a sale. And, they’re native-looking to boot. Frankly, they’re a marketer’s dream.

It should be no surprise, then, that according to a Sellics study, the median-performing RoAS was 323%: An over 3x return on investment. 

Sponsored Products RoAS by percentile: the difference between top and bottom-performing accounts is an additional 3x

Source: Sellics

That’s a great start, but not all Amazon Sponsored Products ads are equal. The top 20th percentile-performers earn a return of 532% of their initial investment – more than 5x

That means the difference between the poorest and best-performing Sponsored Products ads is an additional 3x.

Before you start – Amazon Sponsored Products basics

Before we get down to brass tacks – if this is your first campaign or you’re just getting started with Amazon PPC, it makes the most sense to start here

There, you’ll find answers to all of the Amazon PPC FAQs. From a rundown of each ad format and their placements to setting your budget and keyword match types. 

Here, we’ll only be briefly brushing over the basics. Let’s go!

Glossary of terms 

Before we dive in, here’s a quick refresh on the basics. 

Search terms vs. keywords‘Search terms’ refers to any search query the customer types into Amazon. ‘Keywords’ are what you, as the seller, bid on in your ad campaigns. Depending on the keyword match type used, one keyword can cover multiple customer search terms.
Keyword match typesKeyword Match Types determine the degree of match between the keyword and customer search term for an ad to appear on Amazon. There are three match types available (Broad, Phrase, Exact), all with varying ad targeting precision and monitoring effort required.
Negative keywordsNegative keywords help sellers exclude unwanted customer search terms from their ad campaigns. When utilized effectively, negative keywords can be a powerful tool to help you control your advertising costs on Amazon.
CPC optimization Optimizing your keyword CPC requires you to define your advertising goals from the outset. The optimal CPC can differ wildly based on the goal metrics you are targeting.
Regularly optimizing your keyword CPC ensures the profitability of your ads on Amazon.
Amazon PPC campaign typesThe main difference between running an automatic and manual campaign is that an Amazon manual campaign will give you more accurate results.
In an automatic PPC campaign, you let Amazon run your ads and choose suitable matches for you.
In a manual campaign, you choose the targets you wish your Amazon ad to be displayed for, giving you more significant ad targeting precision.

Automatic vs manual PPC campaigns

Because the difference in campaign type plays an essential role in our recommended Amazon PPC strategy, it’s worth going over in a bit more detail.

Here are the differences between running an automatic versus a manual campaign:

Start here to find the answers to PPC FAQs.

How to group products

Short answer: Don’t group. Create campaigns and ad groups – by ASIN.

Creating one setup per ASIN will give you the most control over your

  • targeting
  • Amazon CPCs
  • budget

Long(er) answer: If you can group your products will depend on your product portfolio’s quantity and diversity. 

Generally products can be grouped if they share the

  • same keywords
  • same profit margin

Here’s an example:

In some ways, an avocado-shaped float and a donut-shaped float have a lot in common. They’re both novelty pool floats shaped like foods. And you can imagine someone seeking out one and ultimately purchasing the other.


Should they be in the same ad group?

No – they’re not interchangeable. The qualities that make them different are significant enough that they’re likely to be reflected in different search terms

Regarding CPCs – if the donut is significantly more popular, the competition’s likely to be more fierce for those keywords, meaning that you’ll need to bid more for those clicks – driving up the CPC for the entire group. You don’t want to end up putting up an avocado where you’ve paid for a donut.

The same logic applies to your budget on Amazon. With both products in the same campaign, you cannot precisely allocate your budget to one product or the other. 

Finally, if their profit margins differ significantly, it won’t be possible to calibrate or even read the PPC campaign’s profitability (or ACoS) accurately. 

However, ultimately, grouping, like campaign building, is also about finding the sweet spot between precision and effort; It might not be feasible for you to create 1,000 groups for 1,000 SKUs because you would need too much time to manage all those campaigns. 

The final word: While it can make sense to group variations – absolutely do not group completely different products.

Keyword research

Compiling a roster of relevant keywords is, well, key. 

If you’ve dabbled in PPC ads previously, you will already have some idea of the most common relevant keywords for your product or product line. 

Even still, and especially if you’re starting from scratch with a new setup, it’s a good idea to do some basic keyword research. 

The following are potential sources:

  1. Brainstorming: consider synonyms and product qualities.
  2. Auto-complete function of the Amazon search field
  3. Sonar: a free Amazon keyword tool by Sellics. 

I could go on about the merits of Sonar, of which there are many. The coles notes are: 

  • Sonar’s suggestions come from real Amazon search terms.
  • You can search by both keyword and ASIN and find related targets automatically ranked by relevance and search volume.
  • Since search terms are regional, you’ll find six international marketplaces to choose from: the USA, Germany, France, Italy, Spain, and the UK. 
  • Sonar, the Amazon keyword tool, is free to use, and your results are downloadable in excel format

The best way to familiarize yourself is to try it – if you haven’t already. Here’s a sneak peek: 

Delegate your keyword research to artificial intelligence:

Sellics Advertising offers two tools to do both keyword research and optimization for you – using either rule-based automation or a full AI solution, called “Autopilot.” Curious? You can try it for free.

Part B: Amazon Sponsored Products – Advanced Amazon PPC Strategy

Step 1: establish an Amazon PPC goal

The first step for starting your Sponsored Products campaign is setting a clear goal.

Assigning a clear goal will allow you to correctly measure your performance according to key performance indicators (KPI’s).

Common goals:As measured by:
Maximizing sales or impressionsBreak-even ACoS
Generating profit Target ACoS

Goal 1: maximize sales or impressions

In a way, sales are always the goal. But the question is, at what cost? If your primary goal is to generate sales, that may come at the expense of profitability.

Prioritizing sales over profit usually means your return only needs to break even with spend, i.e. you need to achieve a break-even ACoS. A higher ACoS means you’re losing money. A lower one, and you’re in profit-making territory. 

Break-even ACoS = profit margin before ad spend

ACoS breakdown

When might sales be more important than profitability? When:

  • launching a new product. Sales beget sales by improving your ranking. Both directly and by potentially garnering reviews and increasing visibility. 
  • increasing brand awareness is your goal. In this case, in addition to conversions, impressions will be a focus KPI.

In these contexts,  you’re using PPC ads to start a virtuous cycle or flywheel that encourages more sales and profit in the future. Usually, the ultimate goal will involve profitability. And: More profits can be reinvested in PPC ads and other marketing to restart the flywheel.

Amazon PPC Flywheel
Look familiar? This model is a flywheel – a term coined by strategist advisor Jeff Collins and employed by Jeff Bezos.

Goal 2: Generating Profit

When maximizing sales, it might be perfectly acceptable to break even or even spend more than you’ll earn from your ads. But to achieve profitability, your investment can’t be equal to or exceed your return. 

To achieve an ad profit you need to define a target ACoS. It’s a simple concept, but the execution can be tricky:

Target ACoS = profit margin before ad spend – target profit margin after ad spend

ACoS breakdown
  1. Calculate your product’s profit margin by deducting all associated costs (manufacturing, shipping, Amazon fees) from the selling price.
  2. The amount leftover (from 1) is both your profit margin and break-even ACoS: if you spend this amount on advertising, you won’t lose or make money – you’ll break even. It’s easiest to understand this number in % of the total sales price.
  3. Based on the % from step two, determine your target ACoS – which will necessarily be a lower percentage.

Step 2: defining the strategy and Amazon PPC campaign structure

Based on comprehensive data analysis and incorporating recent changes to the ad landscape, we have created a new advanced edition of our tried and tested Amazon PPC strategy.

Our Amazon PPC strategy and campaign structure balances achieving the most precision and efficiency with the least effort possible; Giving you control over your ads without dominating your daytimer.

And while the resulting Amazon PPC campaign structure is robust and powerful, it’s also quite flexible – in that it can adapt to any goal.

Amazon PPC campaign structure for 1 ASIN or 1 set of ASINs (how to group products):

  • 1 automatic campaign with 1 automatic ad group
  • 1 manual campaign with 3 ad groups for broad, exact match keywords, and ASIN targeting
  • 1 manual campaign with 1 ad group for category targeting
Sponsored Products Advanced Strategy Blueprint: Full Picture

This setup is leveraging each campaign’s benefits and match type by combining them – so that you can profit from their unique advantages while avoiding their respective shortcomings. 

Automatic campaigns are easy to set up and have a vast reach. But, they can be wasteful to your budget since they lack precision. Manual campaigns have the accuracy needed to craft a more efficient campaign but are a lot more work.

In the Amazon PPC campaign structure above each campaign and ad group has their own function:

  • The automatic PPC campaign automatically performs target research
  • then those targets are harvested and refined through manual campaigns and ad groups (broad match keyword or category targeting)
  • Only the top targets are added to Amazon ad groups with the highest degree of control: an exact match keyword or ASIN ad group.

This one-two punch is the perfect compromise and makes each campaign a cog in a collaborative system. 

To get an overview of the relationship between your Amazon auto campaign, your manual campaign, and their respective ad groups, let’s talk sports for one second.


Your keyword and ASIN research is target “try-outs.”


The auto-campaign is the minor league: You think these targets will do well, enough to be in the ‘game,’ but you’re not exactly placing bets. What you are doing is looking for talent for the major league.


You guessed it: The major league is a manual PPC campaign (specifically, your broad match ad group and category ad groups). Here, targets are expected to perform, but not necessarily at the highest echelon. That is for:


The all-star team! Your manual exact and ASIN ad groups.

Step 3: Amazon PPC campaign setup

Setting up an auto campaign is just that – automatic. Amazon’s algorithm will make its best guess about which keywords and ASINs are a suitable match for your product.

These matches are a valuable resource since Amazon’s determination of relevance will be based on shopping behaviour. (Remember, it’s in Amazon’s interest to turn searches into sales, too.)

Harvesting 101: how automatic target research works

That said, pobody’s nerfect. Amazon casts a very wide net on your behalf.

You should expect that some of the targets (keywords and ASINs) will be irrelevant to your products. 

Others may be relevant – but ultimately not particularly useful. And, you don’t have to guess which is which. 

What makes targets (keywords and ASINs) ‘good’ or valuable?

A target (keyword or ASIN) is worthy of harvesting when it results in a sale. The more the target correlates with a sale for your product, the more valuable it will be to your performance campaign on Amazon.


What counts for performing well will also depend on what you set out to do – your goal. Think of your goal as a lens through which you view your targets and campaigns.


For instance, if your goal is to generate Brand Awareness, you can harvest keywords that have a high number of impressions.

Know that research isn’t one and done. With a constant flow of new search terms (based on changing seasonality and trends) combined with the introduction of new products (ASINs) to Amazon, it’s essential to keep the door open to new targeting opportunities.

The importance of adding negative keywords to your Amazon PPC ad groups

To make the most of this campaign, you’ll want to add any existing keywords that you’re already targeting elsewhere as negative phrase matches. 

You don’t want to waste a major league player in the minor league. Keep your scouts looking for new talent

This is especially important because Amazon’s algorithm prefers known targets, so if you leave the keyword in place in your auto campaign, it’ll steal traffic and keep you from making the most of your research campaign. 

Setup for your manual campaign (broad, exact and ASIN targeting)

Why match type is (so) important for Amazon PPC campaign optimization

Broad match

The broad match setting makes your keywords flexible. Your Amazon PPC ad may appear when customers include these keywords in searches, period. 

They may be: 

  • in any order 
  • include other search terms – even in between your keywords
keyword: pool float
Customer search termsBroadPhraseExact
pool float
kids pool float
pool float novelty
pool donut float
pool cupholder float
donut float

This flexibility makes this ad group type useful for research, specifically for discovering long-tail keywords you might not have thought of. 

The value of long-tail keywords is that their degree of specificity is likely to decrease their CPC while increasing the likelihood of a conversion. Think, “sprinkle donut with bite pool float.” 

Exact match

This is not possible in an exact match campaign, which is the most rigid. Exact match type means it will match the keywords exactly – in the order you’ve written and without additional search terms.

This helps create a more accurate performance-focused ad group because additional keywords can disqualify your product’s suitability for the search in many contexts. 

For example, “cupholder pool float” is both a broad and phrase match for the keyword “pool float”. But suppose your float isn’t a cupholder (or a unicorn pool float, or a pool float for babies). Employing exact match means you don’t have to stress about wasting money on irrelevant permutations (or creating an impossibly extensive list of negative keywords). 

Phrase match

You will soon notice we’ve neglected the phrase match type in our recommended Amazon PPC campaign structure and setup. The main difference between broad and phrase is that phrase match allows search terms to be tacked on before or after your keywords, but not in between.

While this match type is in some ways a “happy medium” between broad and exact, it’s a bit too narrow for research and too broad for a super-refined performance campaign. 

Manual exact match ad group settings

Initial TargetsResearched keywords from Sonar (20) with match type exact.
Initial Negative TargetsNone

If an automatic Amazon campaign is casting a wide net in an ocean of potential targets, your manual campaign is spear-fishing.  

Your exact ad group will target only the best of the best keywords. You can be assured of that because they have been harvested (twice) based on both their search volume and performance. 

Remember, these are your all-stars; they’ve been through the wringer.

Manual ASIN ad group settings

Initial TargetsResearched ASINs from Sonar (20)

Your exact ASIN ad group works in parallel to your exact keyword ad group: Both are ‘all-stars,’ using only the best-performing targets just with different tactics. 

Unlike your exact match keyword ad group, instead of a two-step refinement, there are instead two sources: one is your automatic campaign, and the other is your category campaign. Both have a broad enough reach to find new and potentially profitable ASINs.

Despite similarities, this isn’t a duplication of efforts – far from it. 

ASIN-targeting campaigns have distinct advantages, especially for certain types of products where keywords are less effective

For example, if your products are: 


Example: sand bucket
Products unlikely to have long-tail keywords leave only expensive generic keywords for you to bid on- making it difficult to compete. In other words, the keyword search volume is too high.
An easy up-sell

Example: an air pump

Some products work better together, but shoppers might not think of this until they see it. 
Impulse purchases, gifts, or novelty items

Example: donut-adorned drinking straws
You can use ASIN targeting for the online version of items by the cash register.

In a way, ASIN targeting allows sellers and vendors to use sales tactics as a bricks and mortar store does. ASIN targeting can help shoppers find what they don’t yet know they want.

Initial Negative TargetsAdd initial ASIN targets from ASIN ad group as negative ASINs

Your Category ad group is essentially the ASIN version of your Broad ad group – in the sense that it is both for performance and for refining targets to feed to your exact match (ASIN) campaign. 

Category campaigns are also useful for generating many impressions quickly – for getting your brand ‘out there’ on a grander scale in your own or related categories. 

Targeting by category is especially helpful when you want to promote your products more broadly. For example, if your products are:

New, odd, or rare

Example: bottle-opening bikini 
Because no one knows your product exists, they’re unlikely to search for it.

In this case, keyword search volume is too low.
Fashion and accessories

Example:  a sarong
These products are likely to be browsed and chosen based on visual appeal, especially for clothing and accessories.

Showing them to shoppers might be nudge enough for them to convert or at least attract them to your listing.

Step 4: Amazon PPC campaign optimization

Harvesting keywords and ASINs

Optimizing targets for Amazon PPC campaigns is all about controlling traffic flow. What we call “harvesting” is a two-step process, that involves: 

  1. Sourcing profitable targets from an ad group or campaign with a broader reach to a more precisely targeted campaign
  2. Adding them as negative targets in the source ad group or campaign – to halt traffic to those keywords.

Here’s an overview of the harvesting flows in our recommended Amazon PPC strategy:

Automatic ad groupBroad ad groupRelevant search terms (keywords)IF orders > 1THEN immediately add to broad ad groupAND add as negative phrase keyword to source
Broad ad groupExact ad groupTop search terms (keywords)IF orders > 2
after X clicks
THEN add as exact keyword to exact ad groupAND add as negative exact keyword to source
Automatic ad groupASIN ad groupTop search terms (ASINs)IF orders > 2 after X clicksTHEN add to ASIN ad groupAND add as negative ASIN to source
Category ad groupASIN ad groupTop search terms (ASINs)IF orders > 2 after X clicksTHEN add to ASIN ad groupAND add as negative ASIN to source
X = a ‘sufficient’ number of clicks. (This number is dependent on your conversion rate, but between 10 and 20 is a good rule of thumb)

Negative keywords and ASINs

Unlike regular keywords, there are only two match types for negative keywords on Amazon: exact and phrase match.

If you add “pizza float” to a negative phrase match, no searches containing “pizza float” will trigger your ads. If you added it to an exact match, then related search terms such as “pizza float for kids” would still be included.

In addition to cutting off traffic flow to source campaigns, negative targets are also used to cut off traffic coming from irrelevant or unprofitable keywords. 

If your keyword is a tree, search terms are its branches. Adding search terms as negative keywords is like pruning – you’re only cutting off specific branches in the interest of preserving the overall health of your tree.

— Victor @ Sellics

And pruning is important! Especially given that our studies show that one in four ad dollars is wasted. Adding the right keywords as negative targets is the best way to prevent wasted spend and reduce ACoS.

And how many clicks are ‘sufficient’ to tell if you’ve given your keyword or ASIN a fair shake at making a sale? The exact number will depend on your conversion rate, but we suggest giving it between 10 and 20 clicks.

Automate this task

By using best practice rules sets in Sellics Advertising, you can automatically add negative keywords and transfer top-performing search terms from your automatic to manual campaign, saving time and increasing efficiency. Alternatively, use Autopilot to fully automate your Amazon PPC campaigns.

How to use Sellics for keyword migration

While we’re on the subject of efficiency: You might want to consider dayparting.


Dayparting is a technique used in Amazon PPC strategy that limits impressions to your ad based on the time of day and/or day of week for the purpose of more precise targeting.


There are two principal scenarios where this technique is used:


  • To save budget by avoiding the morning or overnight:

With many budgets quickly burned in the early hours, midday and evening stand to have less competition – which means a lower CPC and ACoS.


Depending on your product line and target audience, it’s probably the case that customers are less likely to make purchases during the wee hours. So that turning off your ads at night can protect from a flood of clicks that are more likely to be click-fraud than clients.


How likely is a customer to buy pool accessories at 2am? Only you know, which brings us to the second reason:


  • Optimizing for days and times that work best for your business. Unless you’re live-tracking your sales from your phone with the Profit app, these insights are likely to come from off-Amazon sources. Either by ‘common sense’ or experience-earned insights.

Bid optimization

Bid optimization for Amazon PPC campaigns is all about controlling your spending and using your ad dollars as efficiently as possible. 

Imagine that bids are a dial to be finely tuned. Too low, and you miss out on valuable placements and revenue. Too high, and you overspend your ad budget, eating away at your profits. 

Without a solid grip on your bid strategy, you risk losing sight of your goal or having an Amazon PPC strategy that’s plain not working. 

Improving your conversion rate is a sure-fire way to increase PPC ad performance.

But how can you tell if yours is “good” or “bad”?


The answer’s not simple, but – thanks to Sellics data scientists – it is easy! You can benchmark your account against others in your category and marketplace now, for free.

The optimal bid is one that agrees with your budget – based on your advertising goal.

Goal is maximizing sales/impressions:
ACoS target value = break-even ACoS = profit margin before ad spend

Goal is achieving target profit margin after ad spend:
ACoS target value = target ACoS = profit margin before ad spend – profit margin after ad spend

But the optimal bid also depends on your product price, and your product page’s likelihood of closing the sale (conversion rate).

Because each target (keywords and ASINs) will have a different

  • CTR
  • conversion rate
  • bid competition level ($)

bid optimization for Amazon PPC campaigns has to happen at the target-level (except for automatic campaigns).

We recommend starting with Amazon’s default bid and adjusting from there. These adjustments to your bid, if done correctly, are what we call bid optimization for Amazon PPC campaigns. 

Keywords/ASINs with good ACoS:
IF ACoS < target value, THEN increase target bid

Keywords/ASINs with poor ACoS:
IF ACoS > target value, THEN decrease target bid 

Keywords/ASINs without conversions:
Reduce bid or pause 

Keywords with few or no impressions:
In case of no impressions, check if the keyword is missing in your product listing. In case of low impressions try increasing the keyword/ASIN bid.

Target ACoS versus your ACoS: When to increase and decrease your bids

Our top tips for bid optimization for Amazon PPC campaigns

  1. Don’t be too bold: test your bid adjustments in incremental steps of between 20 and 30%. This will yield more precise results and help you dial in to the optimal bid more accurately.
  2. Be patient: collect enough clicks before adjusting your bids to make sure you’ve collected enough data to make an informed decision.
  3. Stay agile: CPCs can and will change! And so can the other factors influencing your bid (like your conversion rate, CTR, and even your product costs). That means bid optimization for Amazon PPC campaigns is like cleaning your car after a visit to the beach: a job that’s never done.
  4. Our ultimate tip is this: save time and money by delegating bid optimization to a total AI solution, like Sellics Advertising – where bid adjustments are made automatically according to our recommended strategy.

Step 5: benchmark your Amazon PPC performance 

An optimized Amazon PPC campaign structure and advanced techniques will take you pretty far, but compared to what? Working in a silo, it can be difficult to assess how your ad campaigns are really doing

While we covered the techniques involved in crafting an efficient and optimized PPC campaign, this can’t compensate for a poor click-through or conversion rate.

Improving either is a sure-fire way to reduce ACoS and increase ad efficiency, but to know whether and how much potential you have for improvement, you first need an accurate picture of where you stand.

“Is my conversion rate high or low?”

To find out, what you need is a reliable benchmark – and you won’t get one by googling industry averages: They’re both too general and largely inaccurate, with super-high and super-low performers dragging the middle toward either extreme. 

For a benchmark to be helpful, it should be specific to:

  • Amazon PPC – and Sponsored Products in particular, and
  • your product category, and
  • marketplace.

That way, you can answer: how am I doing compared to my peers – taking into account the unique conditions of my market segment outlined above.

For example, our hypothetical donut float salesperson would benefit from knowing that the Sports & Outdoor category has a median Sponsored Products CTR of 0.36%, and ACoS of 15%.

Amazon PPC bid automation

Rules-based automation uses an “if-then” equation to make helpful changes to your campaigns automatically, without having to:

  • observe the conditions first-hand by pouring over metrics, or 
  • having to make those adjustments yourself.

Based on what we’ve covered so far, you already know the conditions in which you want to adjust your bids. So, you make the rules, and the software makes the adjustments. In the case of bid optimization for Amazon PPC campaigns, if the bid is above your target ACoS, it will be decreased automatically. If it is below, it will be increased automatically.

Implement your own keyword and bidding rules now:

to automate harvesting and bid optimization – with Sellics Advertising.

The main difference between rules-based automation and a full artificial intelligence is that an AI solution goes beyond following simple if/then rules. 

You’re still the one setting the conditions in which you want changes made. However, this time the software uses algorithmic intelligence to, essentially, predict the future so that it can make changes with a more accurate and holistic point of view. 

Not, mind you, by magic but based on a complex web of data points and past performance. It’s a bit much to get into the ‘how’ here, but what you need to know is that Sellics Autopilot can predict the: 

  • expected conversion rate – which is different from the average conversion rate – accounting for seasonality and changes in market conditions. 
  • expected revenue – which, of course, is different from the price of the product you’re advertising – accounting for brand halo sales, multiples, and complimentary purchases.
  • and, the bid-to-CPC ratio, which varies by Amazon product category.

Having predicted these factors, armed with your target ACoS, Autopilot is afforded more freedom to make bid adjustments because it is more informed.

After all, it’s easy to set your bet when you know the outcome of the game.

Dynamic bidding strategies

You may not know it, but, you’re already using dynamic bidding, by default. This allows Amazon to adjust your bids. There are three settings: 

Down only (Amazon’s default setting)

The purpose of automatically decreasing your bids is to reduce waste

If a click is less likely to convert, the bid is automatically reduced by up to 100 %. You might worry that – if applied too aggressively – this could keep you from making sales on targets that are simply slow to convert. 

But, not so. Only targets that are very unlikely to convert would be lowered to 0, making “down only” a quite conservative option and the reason it’s applied automatically. 

Speaking of which, how exactly is the likelihood of converting determined? 

The short answer is that even we don’t know. Amazon uses artificial intelligence based on its extensive shopping behavior data. We can’t be sure about what the determining factors are, but we have a pretty good idea.

Up and down

The purpose of adding automated bid increases is to seize new sales opportunities – in addition to reducing waste. In other words, increasing efficiency. 

If a click is likely to convert, Amazon will raise your bid by up to 100% (double) for placements at the top of the 1st page of search results and up to 50 % for all other placements.

Sponsored Products Dynamic Bidding Range Illustrated

We recommend you give this a try for your optimized ad groups – so long as your goal involves profitability. 

Fixed bids

Alternatively, you can opt out by disabling bid dynamism

In this case, dynamic bidding is deactivated and bids remain the same. Amazon will always use your default bid. 

Because there’s no “up only”, this setting will be your go-to when you don’t want Amazon to stop serving your ad when it’s unlikely to convert. In other words, when you’re looking to maximize sales or impressions at any cost. 

Placement modifiers

There are two – technically three – places Sponsored Products may appear:

  1. Top-of-search (first two Sponsored listings)
  2. on Product pages, and 
  3. the Rest-of-search.

For the first two, Amazon gives you the option of increasing your bid – by placement. Meaning you can increase your bid (by between 1% and 900%) for either Top-of-search or Product pages. 

This is as close as Amazon gets to letting you choose where your Sponsored Product ads appear

So which placement is the best? 

There are two ways to find out. By:

  1. Analyzing the Sponsored Products Placement Report
  2. Having a look at the Sellics Placement Report 
Sellics Placement Report

In either case, what you’re screening for is a lower ACoS, signalling ad efficiency and profitability.

It’s paramount that you do this analysis based on the individual products or, more broadly, product lines. There really is no right answer outside of what is revealed by your own performance metrics. 

Consider, for example, the difference in purchasing behaviours for high ticket versus low ticket products. 

When you are looking to buy a high ticket item – what are the chances that you buy the first one you see?

Probably not very high. If your shoppers are likely to browse and comparison shop, then the Product Details Page is probably a better place to capture their attention. 

And, it’s likely that the reverse is true for low-ticket or staple items.

But please, don’t take our word for it. This is just one example meant to illustrate that one placement really isn’t intrinsically better than the other.

Brand and competitor targeting

Once you’ve established your key Amazon PPC campaigns with optimization flows built in and assessed your performance for potential improvements, you’re ready to move on: to more campaigns!

You can create additional campaigns to achieve more advanced Amazon PPC goals. Usually the next-most pressing priorities are one or both of the following:

Defense: defending your listings from competitors who will try to scoop your sales

A defensive Amazon PPC strategy means bidding on ad placements adjacent to your own products – which you can identify through keyword and ASIN targeting. Occupying the space yourself means depriving others of the opportunity. 

Why would I need to promote my products to an audience that is already looking for them? 

For one, many Amazon shoppers are brand agnostic and, increasingly, come to browse and comparison shop – not just to quickly make purchases and be on their way.

When customers are looking for your products, if you want them to: 

  • Find them, and
  • Not be distracted by competitors

Then you should be implementing a defensive Amazon PPC strategy. 

With ASIN targeting, bid on your own ASINs

Of course, be strategic about it: Choose a combination of similar and complementary products. Not only to steal the space from your competitors, this is a great opportunity to up-sell and cross-sell. 

Also, owning the space around your keywords and ASINs will lend your brand more authority.

For keywords, you’ll want to bid on your own branded keywords

As a starting point, try searching for your brand on Amazon. If you see competitive brands ranking higher than your own products: that’s a sign that some of your (prospective) sales are getting scooped

But, it’s not too late. You want to get in the game by bidding on these keywords yourself and driving up the price – making them less appealing to your competitors. 

The good news is, ACoS tends to be much lower on these targets since shoppers have already expressed interest in your brand. What you’re doing is nurturing the opportunity you’ve been given, by: reducing the friction of finding your products, and encouraging conversions by reducing competitor distractions.

Offense: becoming the scooper – earning incremental sales by promoting your product in competitive spaces 

According to Michael Jordan, the best defense is a good offense. And that’s become a well worn cliche for a reason!

Or, if you’re burnt out on sports analogies (my bad) in business it’s often said that if you’re not growing, you’re dying. And this might be especially true in a space as competitive as Amazon – where prospecting could be considered merely an aggressive defensive Amazon PPC strategy, at least according to MJ.

The flip side of your defense setup, you’ll bid on your competitor’s keywords and ASINs. 

But, again, you want to do so strategically – especially as it’s easy to yield a negative return. After all, they’re not looking for you.

If you’re willing to stick it out, it very well might be worth it in the long run. Gradually, sales you’ve earned that started as searches for your competitor will increase the relevancy of your keywords for those terms, driving up your organic rank

To start, find your competitor’s highest volume keywords, you can again use Amazon’s search bar: You can assume that the served up suggestions – after typing the brand name – are their highest-volume keywords.

Use those as a starting point for your Amazon PPC campaign. The lower-impression terms mean a little less exposure but are lower hanging fruit, since they’ll cost a little less: A good place to start.

Fine tuning from there, adjusting your bids will have to be done with your degree of commitment to this goal in mind – we’ll discuss that next.

For ASIN-targeting, you want to make sure you’re targeting competitor products over which you have an advantage so that you’re giving your products a fair shot. 

Consider ASINs that have: 

  • a higher price
  • fewer ratings, or
  • a lower overall rating

than yours. 

 If you want to compete with a product that is more or less equivalent to yours in these respects, consider adding a coupon or special offer. 

Level-up: category refinements

Category refinements were designed with prospecting in mind. They allow you to refine your category-targeting by:


  1. brand
  2. price range
  3. star rating


The most obvious application is  for the strategy we’ve just discussed: targeting products over which you have a clear advantage – either a lower price or a higher rating. Category refinements allow you to select for these factors without having to do any market research.


Another option, combined with a bit of on-Amazon research, is piggybacking off of big brands’ big advertising budgets. For example, targeting brands who’ve invested in Sponsored Brands lets your Sponsored Products piggyback off of that hard won traffic.


For maximum efficiency, be sure to make use of adding brands and ASINs unlikely to convert as negatives.

A conservative or aggressive approach

In both cases, there is a question of degree. You can choose to pursue either of these goals aggressively or conservatively – which comes down to budget. 

Is the goal (defense/offense) more important than (short-term) profitability?

If the answer is yes, that’s an aggressive approach to the goal and means you should aim for a break-even ACoS.

If not, that’s a rather conservative approach to the goal. In this case, the gains (from an either defensive or offensive Amazon PPC strategy) don’t override your primary goal to earn profits from your ads. In this situation, your target ACoS is the goal. 

Budget allocation and portfolios 

In the same way that campaigns include a cluster of ad groups, Portfolios organize campaigns:

Amazon Advertising Portfolio Structure
source: Amazon Advertising

This feature is helpful for accounts managing a number of different brands or within brands with varied product lines. Its chief benefit is making campaign clusters distinct from each other so that changes and analyses can be performed separately – according to each assigned portfolio grouping.

As always, we consider this an advanced tactic because it comes down to achieving a greater degree of control. The benefit of having separate portfolios is that changes can be applied at a level between the account-level and campaign-level.

The flip side of segregating different campaigns is that the portfolio also means you can consolidate different campaigns. 

Portfolios are especially relevant for products or groupings where you might want to separately manage: 

  • budgets and billing
  • marketing strategies and stores
  • performance metrics 

Using metrics alone can be deceiving.

Learn more about why, according to top PPC strategists, portfolios are a necessary component for understanding your true profit. This, and other advanced strategies are covered in Episode 15 of Sellics Thursday Live.

Conclusion and key takeaways

Levelling up your Sponsored Products strategy is the fastest way to improve your overall performance on Amazon. 

And, getting a solid grip on Sponsored Products lays a strong foundation to build on – both for your greater marketing strategy and additional Amazon PPC formats like Sponsored Brands and Sponsored Display. 

The key to success is building in Amazon PPC campaign optimization with a setup that’s a good compromise between ease and efficiency and gets better over time.
