How do I know if my Amazon PPC is wasting money?

Download the search term report and sort by spend. Search terms with many clicks and no orders, targets running above break-even ACoS, and spend on irrelevant queries from broad or auto campaigns are the clearest signs. Also check whether branded terms are hiding weak non-branded results.

How many clicks before adding a negative keyword on Amazon?

There is no fixed number. Compare a term's clicks with your normal conversion rate: if you usually need around 10 clicks per sale and a term has several times that with no orders, it is a strong candidate. Clearly irrelevant terms can be negated immediately.

Do Amazon ads run when a product is out of stock?

No. Sponsored Products ads stop delivering when the advertised item is out of stock, and also when the listing is suppressed or you do not hold the Buy Box. Check ad status in Campaign manager and stock, suppression and Buy Box status in Seller Central.

Should I bid on my own brand name on Amazon?

Sometimes. Branded ads can protect your listing when competitors bid on your brand, but they can also pay for sales you would have won organically. Review branded and non-branded terms separately so branded results do not hide waste elsewhere in the account.

How often should I check Amazon PPC for wasted spend?

Weekly for active accounts, with a deeper monthly review of placements, budgets and break-even targets. Waste builds steadily through new search terms and changing prices, so short regular checks work better than a large cleanup once a quarter.

Why wasted Amazon ad spend is easy to miss

A campaign can show an acceptable average ACoS while a large share of its spend goes to clicks that never convert. Good keywords hide bad ones in the totals. The only way to find waste is to look below the campaign level, at search terms, targets, placements and individual products.

Before you start, know your break-even ACoS for each product: the ACoS at which ad cost equals your profit before advertising. Our break-even ACoS calculator works it out from price, fees and product cost. Every sign below is measured against that number.

Sign 1: Search terms with spend and no sales

This is the most common leak. Customer search terms that keep collecting clicks without a single order are paying for traffic that does not want your product.

How to check: in the Amazon Ads console, open Reports and download the Sponsored Products search term report for at least 30 days. Sort by spend and filter for zero orders. Compare clicks against your normal conversion rate: if a term has had far more clicks than you usually need for a sale, it is unlikely to turn around.

Add clearly irrelevant terms as negative exact or negative phrase
Lower bids on relevant terms that convert below target
Repeat the check every week or two, not once a quarter

Sign 2: Broad match and auto campaigns bleeding into irrelevant queries

Broad match and automatic targeting are useful for discovery, but left alone they match loosely related searches. If your search term report from these campaigns is full of other product types, competitor accessories or wrong sizes, they are bleeding budget.

How to check: filter the search term report by match type or campaign and read the actual queries. Move proven converters into exact match campaigns where you control the bid, and add them as negatives in the discovery campaign so the two do not compete. Our guide to Amazon PPC campaign structure shows how to separate discovery from performance campaigns.

Sign 3: No negative keywords, or a list nobody updates

If your campaigns have no negatives, or the list has not changed in months, waste is almost certain. Negative keywords are how you tell Amazon what not to show for, and the right list changes as search behavior and your catalog change.

How to check: open a campaign, go to Negative targeting, and see when terms were last added. Check both negative keywords and negative product targets, since product targeting can waste spend on unrelated ASINs too.

Sign 4: Paying for your own brand traffic without a reason

Branded search terms usually convert well, so they make ACoS look healthy. The risk is cannibalization: paying for clicks from shoppers who were already searching for your brand and would have bought through the organic listing. Defending your brand can be worth it when competitors bid on your name, but it should be a decision, not an accident.

How to check: split branded and non-branded terms in the search term report and look at them separately. If most of your sales come from branded terms, your non-branded ACoS may be much worse than the total suggests. Read our guide to Amazon branded keyword bidding for when brand defense pays.

Sign 5: Bids and ACoS above break-even

If a target's ACoS stays above your break-even ACoS, every sale it brings loses money, unless you are deliberately investing in a launch or ranking push with a set end date. Many accounts run bids that were set once and never revisited after fees or prices changed.

How to check: export targeting data, add your break-even ACoS per product, and flag targets running above it with meaningful spend. Then decide which ones are planned investment and which are waste. Our page on what a good ACoS is explains how to set targets by goal.

	Waste	Planned spend
Has a set end date
Irrelevant queries
Above break-even with no goal
Launch or ranking push

Spending above break-even is fine only when it is a deliberate, time-limited investment.

Sign 6: Ads running on out-of-stock, suppressed or non-Buy Box products

Sponsored Products ads only deliver when the product can be bought. Amazon stops serving them when an item is out of stock, when the listing is suppressed, or when you do not hold the Buy Box. Spend may stop on those ASINs, but the campaign loses momentum, and budget shifts to weaker products in the same campaign.

How to check: in Campaign manager, look for ads with a status showing they are not delivering, then review the reason. In Seller Central, check inventory levels, the suppressed listings view and Buy Box status for your advertised ASINs. Plan ads around stock: low-stock products should not be pushed hard right before they run out.

Sign 7: Ignoring placement performance

Sponsored Products ads appear in three placement groups: top of search on the first page, rest of search, and product pages. The same keyword can be profitable in one placement and losing money in another. Placement bid adjustments raise your bid for a placement by a percentage, so a high adjustment set once and forgotten can multiply waste.

How to check: download the placement report for each major campaign and compare ACoS and conversion rate by placement. Lower or remove adjustments where a placement runs above break-even, and raise them only where the data supports it. See our Amazon PPC bidding strategies guide for how adjustments combine with dynamic bids.

Sign 8: Never reviewing performance by time of day

Conversion rates often vary by hour and day. If budgets run out by midday, you may miss your best hours, and if your best hours are the evening, morning spend may be the weakest. Amazon added hours of day to schedule-based budget rules in November 2023, along with hourly performance reporting, so this can now be checked inside the console in supported marketplaces.

How to check: review hourly performance for your top campaigns over several weeks, then use budget rules to put more budget into strong periods. Our guide to Amazon PPC dayparting covers how to read hourly data without overreacting to small samples.

Sign 9: Budgets running out early in the best campaigns

A campaign that hits its daily budget every day while staying under target ACoS is leaving profitable sales unclaimed, while money keeps flowing to weaker campaigns that never run out.

How to check: in Campaign manager, look for campaigns that are out of budget, then compare their ACoS with campaigns that never spend their full budget. Move budget toward the profitable ones first.
