Amazon PPC structure that actually protects profit
Most wasted ad spend comes from structure, not bids. Here is how to organise campaigns by intent, match type and margin so every pound or dollar has a clear job.

The short answer
Work out the break-even ACOS for each product. Split campaigns by purpose: discovery, performance, competitor targeting and brand defence. Move converting search terms into exact match and block the ones that waste money. Judge the whole account on TACoS and profit, not on ACOS alone. The rest of this guide explains each step.
Step 1: calculate break-even ACOS per product
Break-even ACOS is your profit margin before advertising. Take the selling price, subtract Amazon fees and your landed product cost, and divide what is left by the selling price.
Example: a product sells for 30.00. Amazon fees are 9.50 and landed cost is 8.00. Profit before ads is 12.50, which is 41.7% of the price. Any campaign running below a 41.7% ACOS makes money on the ad sale itself. Above it, you are paying for the sale.
Do this for every product. A 35% ACOS is healthy on this item and a loss on one with a 25% margin, which is why products with different margins should not share a campaign.
Step 2: give every campaign one job
- Discovery (automatic and broad match): low bids, used to find new search terms. Not expected to be efficient.
- Performance (exact match): proven keywords with the highest bids and the tightest control.
- Phrase match: the middle ground for capturing variations of proven terms.
- Product targeting: your ads on competitor and complementary product pages.
- Brand defence: your own brand terms, so competitors cannot buy the top spot cheaply.
Keep one product or one tight product group per campaign. Use a naming convention that states product, type and match type, for example: Kettle 1.7L | SP | Exact | Performance. When names are clear, problems are easy to find.
Step 3: run the weekly harvesting loop
- Download the search term report for discovery campaigns.
- Move search terms with sales at an acceptable ACOS into the exact match performance campaign.
- Add those same terms as negative exact in the discovery campaign, so the two do not compete.
- Add irrelevant or costly non-converting terms as negatives. Wait for enough clicks before judging: a term with five clicks and no sale has not been tested yet.
This loop is where most of the profit improvement comes from. It steadily shifts spend from guessing to knowing.
Step 4: set bids and budgets on purpose
- Start exact match bids near Amazon’s suggested range, then adjust towards your target ACOS using real conversion data.
- Use placement adjustments when the data shows top of search converts better for a campaign.
- Make sure performance campaigns never run out of budget mid-afternoon. If money is limited, cut discovery first.
- Consider scheduling by time of day only when you have hourly data showing a clear pattern. Without evidence it just reduces sales.
Step 5: match goals to the product’s stage
- Launch: ACOS above break-even is acceptable for a planned period to earn ranking and reviews.
- Growth: aim near break-even while organic sales build.
- Profit: hold ACOS well below break-even and defend key positions.
Write the stage and target next to each product, and review it monthly.
The number that shows the truth: TACoS
TACoS is total ad spend divided by total sales, including organic sales. If ACOS looks good but TACoS keeps rising, ads are replacing organic sales instead of adding to them. A stable or falling TACoS while sales grow is the sign of a healthy account. Track it by product and for the whole account.
Common mistakes
- Mixing match types in one ad group, so you cannot tell what is working.
- Advertising products with poor listings. Ads send traffic; the listing has to convert it. Fix images, price and reviews first. See listing optimization.
- Changing bids daily. Most keywords need at least a week of data.
- Chasing a low ACOS so hard that total sales and ranking fall.
- Forgetting to bid on your own brand name.

Frequently asked questions
How many keywords should be in one ad group?
Fewer is easier to control. For exact match performance campaigns, a handful of closely related keywords per ad group is typical, and some sellers isolate their most important terms in single-keyword campaigns.
Should I use automatic campaigns at all?
Yes, as a discovery tool with modest bids. They find search terms and products you would not have thought of. They should not be where most of your budget goes.
How often should I optimize Amazon PPC?
Weekly for search term harvesting and bid changes, with a deeper monthly review of structure, budgets and targets. Daily checks are useful only for spotting budget or stock problems.
What is a good TACoS?
It depends on margin and stage. Many established products run in single digits to low teens as a percentage, and launches run much higher. The trend matters more than the figure.
