Don’t Run Sponsored Product Ads vs Big Brands To Reduce ACoS on Amazon

Odds are, you likely have found the most successful players in your space, entered them into Helium 10 or Jungle Scout, and downloaded their keywords.

Then, you selected the ones with the most search volume, added them to your listing, and started running Sponsored Product Listing ads on them.

This was a mistake unless you have thousands of reviews, a fantastic Unit Session Percentage, and sales history.

In other words, if you can stand shoulder-to-shoulder with the brands that sit at the top of search results.

Have a look at this:

Don't Run Sponsored Product Brands Ads Against Lots of Reviews - How To Reduce ACOS on Amazon - The Source Approach - Amazon Consultant

If you don’t have 20,000 reviews, even if you offer a fantastic price, customers will click on you, but they won’t buy.

This has everything to do with value framing.

You want to de-frame yourself from the competition.

So, instead, to reduce ACoS on Amazon, focus on lower volume, long tail, and buyer intent keywords that they’re not competing on until you build enough momentum.

Not only will you get clicks and not sales on these huge volume keywords, but you’re swimming with the sharks and the clicks cost a lot.

You can run those same competitors through the same tools but focus on the buyer intent keywords where they’re in position 50 – 100.

Focus where they aren’t.

Speaking of not copying the big brands on Amazon…

 

Stop Emulating The Big Brands To Reduce ACoS on Amazon

One of the other common mistakes you see is looking at the big successful players in your space and copying what they do.

The problem? They make mistakes and get away with them.

You see their estimated monthly sales and you create a correlation with that and what you see on Amazon. This couldn’t be farther from the truth.

What you don’t see are:

  • All the Facebook Ads they run to Amazon
  • All the Instagram Ads
  • All the Google Ads
  • The Amazon Influencers they partner with
  • The traffic they drive from their huge email lists
  • The mega PR they get from major publications
  • & more

Couple that with all of the retargeting and display ads, they’re everywhere. This builds continuity and trust in the eyes of the consumer, because they see these brands everywhere they go. That means, they can get away with things like this:

  • Poor copywriting
  • Poor color-psychology
  • Bad graphic design best practices
  • Bad A+ Content
  • No product videos or bad product videos

Focus on proven, age-old techniques to earn consumer trust, boost perceived value and drive sales when you don’t have tons of reviews, aren’t everywhere online, and don’t have huge advertising budgets.

 

Reduce ACOS With Ad Optimization

Amazon PPC Campaign Structure

Auto Campaigns (Discovery)
Mining for new keywords
Broad / Phrase Match (Refining)
Narrowing down intent
Exact Match (Profitability)
High conversion, controlled bids
↓ Move winning keywords down the funnel ↓

In my Amazon Consulting experience, the very first place to start to reduce your ACoS on Amazon is the front lines. The ads themselves.

Your conversion rates on Amazon impact how much you are going to pay per click.

If Amazon’s algorithm does not think you’re going to result in a sale, you will not get as many impressions and you will pay more for clicks.

So, if you are sending lots of traffic to your listing that will likely not convert, you are driving up your ACoS on Amazon and making your other campaigns cost more across the entirety of your ad console.

Make sure you’re targeting the right customers and not showing ads to the wrong potential customers.

Buyer Intent Keywords

If you’re running your competitor ASIN’s through tools like Helium 10 or Jungle Scout, selecting the most searched keywords, adding them to your listing and then running ads on them, you’re making a big mistake.

Buyer intent keywords are keywords that indicate the customer has already done the research and know exactly what they want. So, if they see your offer and click on it, they are very likely to buy, thus, increasing your unit session percentage.

Example:

Brand Awareness: K-Cup

Buyer Intent: Recyclable Organic French Roast K-Cups Fair Trade Certified

You want to focus your efforts on Buyer Intent keywords if you’re looking to decrease ACOS on Amazon PPC.

Negative Keywords

Whether you’re running automatic Amazon ads on your Sponsored Product Listings or manually targeting customers with your own keyword research, you will want to always optimize these.

How To Reduce ACOS By Setting Amazon PPC Negative Keywords:

  1. Run your search terms report
  2. Identify the terms that are driving clicks, but not converting sales
  3. Determine which of those keywords are not relevant for your products or likely don’t make sense.
  4. Add them to your Negative Keywords List

Reduce Bids on Poor Performing Keywords

As you’re looking through your Amazon Campaign, view the Targeting tab.

How To Optimize Your Bid Strategy To Reduce ACoS:

  1. From within the Targeting Tab, click on Columns
  2. Choose Customize Columns
  3. Add Impressions
  4. View your keywords that you are targeting and identify the keywords that have a high ACoS over 50% (this one is a rule of thumb, some have better product margins than others.).
  5. If the ACoS is really high, shut off the keyword.
  6. If the ACoS is around 50% or close to your target ACoS (TACOS), then decrease the bid by about 45% or 50%.
  7. Now, if your ACoS is great, step on the gas and increase the bids.

 

Reduce ACOS With Amazon Influencers

Did you know Amazon has had Amazon Influencers referring to Amazon since 1996 and they’re responsible for over 37% of Amazon’s traffic today?

An Amazon Influencer has audiences that visit their sites, videos, blogs & more RIGHT BEFORE they are ready to make a purchase. They go to their blogs, get the information they need and then goto Amazon and make a purchase.

Reduce ACOS With Amazon A+ Content

If you’re selling on Amazon Seller Central and are Brand Registered, it’s called Amazon A+ Content. (Learn more about Amazon Brand Registry here: Amazon Brand Registry: The Complete Guide)

Essentially, Amazon lets you build landing pages on your Amazon listing with extra content that is not allowed in the Product Description area.

These convert EXTREMELY well because they are mini-landing pages.

Reduce ACOS With Amazon Reviews

It’s no secret that the more Amazon reviews you have, the higher you show up in Amazon search results.

This is because you will have higher conversion rates the more reviews you have.

This directly impacts how much you’re going to pay for ads.

DO DON’T
Use the Amazon Request a Review Button Incentivize reviews
Use follow up email sequences Ask for positive reviews only
Use product inserts Use manipulative language (“small family-owned business”)
Use the Vine program Leave reviews on your own products or have friends do it

Can You Use ChatGPT To Reduce ACOS on Amazon?

Yes, in my article ChatGPT For Amazon Sellers I share several prompts that will help you use ChatGPT to decrease ACOS on Amazon.

How Do I Lower My ACOS on Amazon?

You lower your ACOS on Amazon by converting more sales on the targeting mechanisms you’re using such as Keyword Targeting, ASIN Targeting, and Display Targeting. Consider adjusting your top of search placement bids based on where you are converting the most. Target Buyer Intent keywords rather than very broad brand awareness style keywords. Focus on optimizing your listings for the keywords you are bidding on.

What is a Good ACOS on Amazon?

The average ACOS on Amazon fluctuates between 30% – 40%. A good ACOS on Amazon is largely dependent on your own profit margins. In categories like jewelry with extremely high-profit margins, a 40% ACOS would be good, but in a category like health supplements, you need an ACOS closer to 20% and below. The lower the ACOS the better.

How is ACOS Calculated on Amazon?

ACoS on Amazon is calculated by dividing the ad spend by target sales and is represented as a percentage.

ACoS = Ad Spend/ Target Sales * 100

For example, if an ad campaign generates $1,000 in sales and spends $200 to generate those sales, the ACOS on Amazon would be 20%.

ACoS= 200/1000 * 100% = 20%

What is Amazon PPC ACOS?

Amazon PPC ACoS is a metric that represents the ratio of advertising spend vs target sales.
