In this tutorial, I will explain how Sellerboard’s keyword-level ACOS and profit margin optimization logic works.

This is important because one campaign can contain profitable keywords, weak keywords, expensive keywords, and keywords that look good by ACOS but still hurt real profit.

The goal is to understand which keywords deserve higher bids, which ones need lower bids, and which ones should be filtered out before they waste more budget.

What Is Keyword-Level PPC Optimization?

Keyword-level PPC optimization means judging each keyword based on its own results instead of judging the whole campaign as one average.

This matters because campaign averages can hide what is really happening.

One keyword may be producing profitable orders while another keyword in the same campaign may be spending money without converting.

Sellerboard helps you look deeper by connecting keyword performance with product economics.

Why ACOS Alone Can Be Misleading

ACOS is helpful, but it is not enough by itself.

A keyword with 25% ACOS can be profitable for one product and unprofitable for another product.

The difference comes from the product’s real margin.

If your costs, fees, refunds, and other expenses are high, a keyword can look acceptable by ACOS but still leave very little profit.

1. Use ACOS to understand ad spend compared to ad sales.

2. Use break-even ACOS to understand the maximum ad spend your margin can tolerate.

3. Use profit margin to understand whether the keyword supports your business goal.

4. Use conversion data to understand whether the traffic is actually relevant.

What Data Sellerboard Uses For Keyword-Level Logic

Keyword-level optimization works better when Sellerboard has clean product and cost data.

The system needs more than clicks and sales to understand whether a keyword is good for your business.

It also needs the cost structure behind the product.

Target ACOS vs Target Profit Margin

Sellerboard Smart Portfolios can be built around Target ACOS or Target Profit Margin.

Target ACOS is usually easier to understand because it is tied directly to ad spend as a percentage of ad sales.

Target Profit Margin is more business-focused because it asks whether the product still keeps enough margin after advertising and costs.

The better choice depends on your campaign goal and how closely you want PPC to follow real profitability.

How Sellerboard Thinks About Keyword Bid Changes

Sellerboard’s bid logic is designed to match keyword bids with the goal you choose.

If a keyword performs well enough compared to your ACOS or profit goal, it may deserve more exposure.

If a keyword spends too much compared to its sales and profit, the bid may need to move down.

The point is not to raise or lower bids randomly.

The point is to compare each keyword against the product’s real profit potential.

Break-Even ACOS In Simple Words

Break-even ACOS tells you how much ad spend a product can tolerate before profit is gone.

If your keyword ACOS is lower than break-even ACOS, the keyword may still leave profit.

If your keyword ACOS is higher than break-even ACOS, the keyword may be losing money unless the goal is launch visibility or ranking support.

This is why the same ACOS number can mean different things for different products.

1. A high-margin product can usually tolerate a higher ACOS.

2. A low-margin product usually needs tighter ACOS control.

3. A launch product may temporarily accept weaker ACOS for discovery or ranking goals.

4. A mature product usually needs stricter profit protection.

When To Increase A Keyword Bid

Increasing a keyword bid should be based on proof, not hope.

A keyword may deserve a higher bid when it has enough data, converts well, and stays inside your target ACOS or profit margin logic.

Before raising a bid, also check inventory and ranking goals.

1. Increase a bid when the keyword has stable conversions.

2. Increase a bid when the keyword is below your target ACOS or supports your target profit margin.

3. Increase a bid when budget is available and stock can support extra orders.

4. Increase slowly when the keyword has limited data but looks promising.

When To Decrease A Keyword Bid

A keyword bid should usually move down when the keyword is spending too much for the return it creates.

This does not always mean the keyword is bad.

Sometimes the keyword is relevant but the bid is too high for the product margin.

1. Decrease a bid when ACOS is above the target and profit is weak.

2. Decrease a bid when clicks are coming in but conversions are not strong enough.

3. Decrease a bid when the keyword is relevant but too expensive for the current margin.

4. Decrease carefully when the keyword has strategic ranking value but is not profitable yet.

When To Add Negative Keywords Or Filter Poor Traffic

Some keywords and search terms should not only receive lower bids.

They may need to be blocked, excluded, or moved into a stricter structure.

This is especially true when a search term spends repeatedly without producing orders or profit.

1. Add negative logic when a search term is clearly irrelevant.

2. Add negative logic when the term collects enough clicks without sales.

3. Add negative logic when the term attracts shoppers who do not match the product.

4. Be careful with negative keywords when the product is new and data is still limited.

Manual Recommendations vs Autopilot

Sellerboard can support both manual approval and autopilot workflows for PPC optimization.

Manual recommendations are useful when you want to review suggested bid or keyword changes before they go to Amazon.

Autopilot is useful when your rules are clear and you trust Sellerboard to apply repetitive PPC changes automatically.

Most sellers should start with more review before moving into deeper automation.

How This Logic Connects To Smart Portfolios

Smart Portfolios use keyword-level logic inside a broader automation workflow.

They are designed to discover keywords, optimize bids, allocate budget, and scale what works.

The keyword-level ACOS and profit margin logic helps Sellerboard decide how individual keywords should behave inside that automation system.

How To Review Keyword Recommendations In Sellerboard

Sellerboard’s PPC Recommendations area can show bid suggestions and keyword suggestions generated by your automation rules.

This helps you review suggested actions before applying them manually when automation is not fully on.

The recommendations can include bid changes, well-performing search terms, and poorly-performing search terms.

1. Open Sellerboard.

2. Go to PPC.

3. Open Recommendations.

4. Review bid recommendations, strong search term recommendations, and weak search term recommendations.

5. Accept, postpone, or adjust the recommendation based on your campaign goal.

Common Keyword-Level Optimization Mistakes

Keyword-level logic is powerful, but it still needs good judgment.

Avoid these mistakes when using ACOS and profit margin to manage Amazon PPC.

1. Do not judge every product by the same ACOS target.

2. Do not raise bids before checking profit margin and inventory.

3. Do not cut a keyword too early when it does not have enough clicks or orders yet.

4. Do not ignore refunds and fees when judging whether a keyword is profitable.

5. Do not put autopilot on before your cost data and rules are clean.

6. Do not forget that PPC goals can change between launch, optimization, and scaling stages.

Keyword-level ACOS and profit margin optimization helps you make better Amazon PPC decisions because every keyword does not deserve the same treatment.

Some keywords deserve higher bids because they convert and protect profit.

Some keywords need lower bids because they are relevant but too expensive.

Some keywords or search terms should be filtered out because they keep wasting spend without enough conversion value.

Sellerboard helps you review this logic with real product economics, including COGS, fees, refunds, PPC spend, ACOS, profit, and margin.

Start with manual review, understand the recommendations, and then move into autopilot only when your goals and data are clean.
