This article is step 3 of our step-by-step guides through Amazon PPC Sponsored Products


This is a condensed guide to creating and managing your Amazon Sponsored Products Campaigns.

This guide will explain some Best Practice to follow as well as how to use Trendle Analytics to optimise and automate your campaigns.

You do not need to follow our best practice if you don’t want to. There are many ways to manage successful campaigns, you are free to choose your own way.

How to structure you Sponsored Product Campaigns 

Golden Rule: Only advertise one SKU/ASIN/Product per Campaign

There are several reasons to do follow this second best practice rule:

  • Each product has different keywords that customers will search for. Putting ‘walking shoes’ and ‘dancing shoes’ in the same Advertising Campaign will return very different keywords and customer search terms.
  • In addition, filtering through keywords to understand which are relevant and which are not, is easier when you know to which product they refer to. The data we gather from Amazon does not allow us to determine down to keyword level which SKU it relates to. We can only do this at Campaign and Ad Group level. Also, one keyword may be relevant for two slightly different products in your portfolio. By splitting your SKUs into individual campaigns will help you gauge for which product the keyword works best.
  • Each product has a different cost and selling price. If you set yourself a target ACoS for each keyword, you can only achieve this if you know the exact spend per product. And this is only possible if you include only one SKU per Advertising Campaign or Ad Group.
  • More importantly, the more granular you are, the more data you have and the more control you have. You can allocate your budget with much more ease and flexibility across your products. With one product per campaign, you can increase or decrease your daily spend budget for specific products. For example, if your walking shoes have had a big increase in sales and you will run out of stock, you may want to immediately lower your daily budget until you get more stock in, but without impacting your bid price. But if you have your walking shoes and your dancing shoes in the same campaign, you will have to go through each keyword (note: you could do this at the Ad Group level, but we strongly recommend against doing this).

Note: If you have size variations or colour variations, you may include these SKUs into the same Advertising Campaign as the search terms the customer will use will be very similar. However we still recommend creating a different Ad Group per colour/size variation, or even a different Campaign per colour/size variation. You need to decide how closely related the items are.
Alternatively, you can choose to advertise only the SKU that has the most sales from your variation as the goal is to drive traffic to your listing.

Best practice Variant 1 – Process – From Broad to Exact

Step 1. (optional) You can create an Automatic Campaign if you do not have enough keywords to enter in a manual campaign. This is a good option if you’re lazy or want to see what Amazon’s creative algorithms think your product is.
In general we recommend you NOT to do an automatic campaign as this is often waster ad spend. Instead, perform good keyword research and add the relevant keywords straight to your manual campaign.

Step 2. Create a Manual Campaign

2.1 Add Keywords

Add any keywords which you think are relevant. Look at what is in your title, description and backend keyword. You can also use tools such as Keyword Inspector or merchant words or google trends and others to get other related keywords. If you are running an automatic campaign, add any keywords from the ‘customer search terms’ which are relevant.

Add these keywords in an AdGroup with default Match Type set to ‘Broad’.

2.2 Negative Exact bad Search Terms

From Day 2 of the campaign, log in to see which search terms Amazon is choosing to display your ads based on your broad keywords. You can already Negative Exact Match the obvious Customer Search Terms which you know are irrelevant for your product.

For example if your broad keyword for your dancing shoes is “Light Shoes”, and a search term is “Nike running light shoes”, then you can Negative Exact that search term before you even occur a click and therefore a wasted spend. Log in daily for the first week to be prevent wasted spend.

After that you can just log in weekly to see if there’s anything new customers have been typing (this is good to spot trends early)

You can also start creating rules such as “If no sales after 5 or 8 clicks then list as negative”

2.3 Move best Search Terms to Phrase and/or Exact Ad Groups

Wait 7-14 days before proceeding with this step! Why?

(a) Amazon reporting only shows sales following from a click 48-72hours (2-3 days) after the event. This means with 7-14 days data, you only really have 5-12 days of usable data.

(b) You need to avoid seasonality. By that we mean: your products will probably not sell at the same rate on Sunday as they will on Wednesday. So trying to have the weekend data blended into the week data will give you more accurate insights.

(c) You need to give your campaign time to work and for Amazon to find the relevant Search Terms.

Ok, so you’ve now patiently waited 7-14 days and have already filtered out obvious bad search terms to avoid incurring pointless costs.

Now you can take the best performing search terms and move them to a Phrase and/or Exact Ad Group.

2.4 Optimise Phrase and Exact Ad Groups

As before, continue to Negative Exact Match the obvious wrong search terms in the “Phrase” Ad Group.


Best practice Variant 2 – Process – From Exact to Broad

Step 1: Find out your most relevant keywords

Step 2: Add these in ad groups of up to 250 keywords, place the keywords you team most relevant in the first few ad groups. Place higher ad group bid for these ones, and lower for the other keywords you consider long tail

Step 3: Set-up your recommendation and/or automation rules specific to that campaign.

A classic rule would be: If 0 orders after 8 clicks, list as negative exact

Step 4: Take your best performing keywords and add them in to new ad groups in Phrase and Broad matches AND negative exact. This will allow you to do 2 things: First, find long tail keywords for a keyword you know works well for you. So theoretically there should be some long tail related search terms that would work well as well, which you can then add as keywords. Second, by adding it as negative exact in this new ad group, you avoid cannibalising your already well performing Exact match in the original ad group.

Here’s an example of a full campaign structure setup with rules:

Important Notice: The recommendations below are no guarantees for success. Each niche is different and Amazon is a very dynamic marketplace. Therefore you may need to adjust the metrics presented below to fit your products niche better.

4.1 Create an Automatic Campaign to discover what customers are typing in the search bar in order to find and buy your product. We recommend not to do this, but instead to do detailed keyword research. If you still want to launch an Automatic Campaign then read on, if not go to 4.2

This is an optional step. An Automatic Campaign is a great way to just let Amazon do the leg work and find what search terms are the most relevant. You can then blacklist (Negative Match) the search terms which are not relevant/profitable and move the good keywords to a manual campaign where you have more control and flexibility.

If you already have a good list of keywords and you don’t want to spend budget on an Automatic Campaign which may be hit and miss, you can go straight to creating a Manual Campaign with one Broad Ad Group (see next step)

  1. Create one automatic campaign per Product
  2. If you have Product Variations, then create an Ad Group per variation.
  3. Set a daily budget of $10-20 and a bid price of $0.50-1.20
  4. Wait at least 10-14 days before making any changes to your campaign.
    Then, do the following once a week:
    4.1 If the search term has 0 orders, 1000+ impressions, 5+ clicks and lower than 0.70% CTR –> list as Negative Exact.
    4.2 If the search term has at least 1 order –> move to manual campaign (see next step)
    4.3 Search term has 0 orders, 1000+ impressions and greater than 0.70% CTR –> move to manual campaign (see next step)
    Tip: You can set and edit the recommendation settings by going to the “Recommendation Engine”. You can also delete and create as many custom recommendations as you want.
  5. After 30 days you will have discovered nearly all the search terms relevant to your product and variations.
    We recommend you reduce your bid price and/or your daily budget.
    Don’t stop your campaign, there may always be some new search terms appearing due to seasonality, new trends, competition changes etc.

4.2 Manual Campaign – 1 ad group only (Broad)

After patiently waiting at least 14 days, you can start to take the best search terms from the Automatic Campaign and move them to a manual campaign (see step above in Automatic Campaign).

If you did not do an Automatic Campaign, you will start here with the keywords you have found yourself.

  1. Create one manual campaign per product
  2. Create 1 ad group per variation called Broad” and with Match Type Broad
    Hint: Make sure to always name your ad groups in a way which will be easy for you to identify them. This will help a lot you later.
  3. Take the best search terms from the automatic campaign and move them to the Ad Group (see step above in Automatic Campaign)
    For example, if the term “summer cotton shirt” is a great search term in the automatic campaign, then copy that as a keyword to the Broad ad group.
    Note: When moving a search term from the automatic campaign to the manual campaign, make sure to mark it as “Negative Exact” in the automatic campaign. This will optimise your manual campaign performance.
  4. Manually add your own keywords. You can do this directly in Trendle Analytics app.
  5. Set the daily budget to $20-30
  6. Set the keyword bid to $0.75-1.50.
  7. Wait at least 10-14 days before making any changes.
    6.1 If search term associated to a keyword has 0 orders, 1000+ impressions and 5+ clicks –> add as Negative Exact Match keyword in that Ad group only
    6.2 If keyword has 3+ orders and ACoS is within your target and CTR is over 0.40% –> This is a High Performer (HP). Increase the bid over the next few weeks to drive even more sales. Make sure the bid remains within your profitability targets.
    Note: Increasing your bid may not necessarily increase your sales. Use the graphs to understand how bid price changes impacted performance until you find the sweet spot.
    Note: The sweet spot may be temporary (competition, seasonality etc are all external factors over which you have little information and control), make sure to continuously evaluate your keywords.
    Tip: The application will recommend the maximum bid you can set in order to remain within your profitability target.
    6.3 If keyword has 3+ orders, ACoS is within your target and CTR is lower than 0.40% –> This is also a HP. You may want to check what within the title, image and price could increase the CTR.
    6.4 If the search term has 0 orders, 1000+ impressions, 5+ clicks and lower than 0.70% CTR –> list as Negative Exact in that Ad group

Tip: You can set and edit the recommendation settings by going to the “Recommendation Engine”. You can also delete and create as many custom recommendations as you want.

4.3 Add Exact and Phrase ad groups to your manual campaign

  1. Create 2 ad groups called “Phrase” and “Exact” with the associated Match Types.
    Make the Match Type for keywords in each ad group match the name. For example, all keywords in the “Exact” campaign should have a Match Type of “Exact”.Hint: Make sure to name your ad groups in a way which will be easy for you to identify them. This will help a lot you later.
    Here’s why:

    • Guiding principle: The more granular you are with your data, the better the quality of that data, and the better your campaigns will perform as a result. However, if you mix too many products per campaign then your data will not be as rich. In addition, the more granular you are, the more control you have.
    • By including only one SKU per campaign and using these 2 Ad Groups, you can be much more granular, flexible and quick in your keyword selection and bid adjustments.
    • It also allows you to have the same keyword under the 2 Match Types running in parallel which will tell you under which Match Type the keyword offers best profitability.
    • Like with all data, the more granular you can be the better. Doing one ad campaign for shoes and then splitting all your shoes by Ad Group will give you less detailed information and flexibility.
    • You allocate a daily spend budget per campaign. So if you have several products in the same campaign, it might be that some keywords for one SKU end up using up all your daily budget, leaving nothing for other products to be advertised. By splitting your products into individual campaigns you can easily adjust your daily budget spends on a per product basis and be in maximum control of your spending.


  2. Take the best search terms from the Broad ad group and move them to each Phrase and Exact Ad Groups
    For example, if the term “summer cotton shirt” is a high performing keyword in the manual campaign, then copy that as a keyword to the Broad ad group, the Phrase ad group and the Exact ad group.
    Note: When moving a search term from the broad ad group to the Exact and Phrase ad groups, make sure to mark it as “Negative Exact” in the Broad ad group. This will optimise your campaign performance and budget. 
  3. After a few weeks look to see if a keyword is performing significantly better or worse in any of the Ad Groups.
    For example, if Keyword “cotton shirt” is doing great in Exact but not so great in Phrase and Broad, then lower the bids progressively over several weeks until you get them to be profitable (even if this means you only get 1 click every few months). We don’t recommend you remove or pause that keyword.
  4. Keep managing each keyword bid to increase your sales whilst remaining within your ACoS target
