Amazon PPC Keywords With Spend but No Sales: Find and Fix

Almost every set of Sponsored Products campaigns we review shows the same pattern: a cluster of keywords that pick up clicks every day, eat budget and never produce an order. Individually they look like small change. Added up across a month and several campaigns, they're a cost line nobody actually decided on. Finding Amazon PPC keywords with spend but no sales is the fastest way to win back budget without losing sales. This guide shows how to find them, how to tell whether they really should go, and how to fix them without breaking anything.

Why Amazon PPC keywords spend without selling

Wasteful keywords almost always come from one of these situations:

Broad or phrase match that's too loose. The keyword is right, but the search terms it triggers aren't. "Insulated water bottle" can put your ad in front of people searching "kids water bottle" or "water bottle lid".
Auto campaigns nobody cleans up. Amazon picks the targets, and if nobody reviews the search terms, irrelevant ones stay live for months.
High bids on generic keywords. Top placements, expensive clicks, low conversion.
Problems that aren't about the keyword. The product was out of stock, lost the Buy Box or was priced out of the market. The keyword gets clicks, the listing doesn't convert.

That last one is what most people skip, and it's why "cut everything that doesn't sell" isn't a strategy.

The 5-step workflow: find, understand, prepare, approve, execute

1. Find

Set your filter before you look at the data, or you'll end up judging by eye. A reasonable starting filter:

a 14-30 day window, excluding the last 2-3 days (ad-attributed sales arrive with a delay);
at least 15-20 clicks with zero orders (below that, it's noise);
sorted by spend, so you start with what actually matters.

These thresholds are a starting point. Adjust them to your average price and conversion rate.

2. Understand

For each keyword on the list, ask three questions before touching it:

Was the product sellable? Stock available and Buy Box held during the period. If not, the keyword isn't the problem.
Which search terms did it trigger? Often the keyword is fine and two or three search terms are doing the damage.
Is it strategic? Your brand name, or a term where you want to defend position, may follow different logic from immediate return.

3. Prepare

Only now do you pick the action, and it isn't always the same one:

Lower the bid when the keyword is relevant but too expensive for its conversion rate.
Pause the keyword when it simply isn't relevant to that product.
Add a negative keyword (exact or phrase) when specific search terms are the problem, especially in auto and broad-match campaigns.

4. Approve

Before anything is written, review the full list of changes: keyword, campaign, current value, new value. This is where you pull out the exceptions ("not that one, it's our brand").

5. Execute and re-check

Apply the changes and note the date. Two weeks later, check spend and sales on those campaigns again. The goal is to spend less for the same sales, not just to spend less.

Doing it with AI: 4 prompts to copy

Manually, this workflow needs the search term report, the keyword report, stock and Buy Box data, and a spreadsheet to join them. With your seller account and Amazon Ads connected to ChatGPT or Claude through an MCP connector, you can follow the same steps in conversation:

Find keywords in my Sponsored Products campaigns on amazon.com that, over the last 30 days (excluding the last 3), had at least 15 clicks and zero orders. Show keyword, match type, campaign, clicks and spend, sorted by spend.

For the top 10 keywords on that list, check whether the advertised products had stock available and held the Buy Box during the period. Flag the ones where the product, not the keyword, is the problem.

For the remaining keywords, show me the search terms that drove the most spend without sales. Suggest one action for each: lower bid, pause or negative keyword, with the reason.

Prepare the proposed changes, excluding any keyword that contains my brand name. Show me a preview with current and new values, and wait for my confirmation before applying anything.

With Vendooly, every write to Amazon Ads (bids, keyword status, negatives, budgets, campaign status) shows a before → after preview and runs only after your explicit confirmation. The AI does the digging and the preparation; what gets cut is your call. The connector includes 44 tools dedicated to Amazon Ads, across Sponsored Products, Sponsored Brands and Sponsored Display.

Mistakes to avoid

Judging on too few clicks. A keyword with 6 clicks and no orders doesn't tell you anything yet.
Looking only at the last few days. Attributed sales arrive late, so you risk cutting keywords that were about to convert.
Cutting without checking the product. If the listing wasn't sellable, pausing the keyword fixes nothing.
Negatives that are too broad. A phrase-match negative on a generic word can block search terms that do sell.
Not re-checking. Without a review after two weeks, you don't know if you saved money or just lost visibility.

Don't wait for month-end

Keywords that spend without selling pile up quietly. That's why, if Amazon Ads is connected, Vendooly's Monday recap lists the keywords that spent without selling over the last 14 days, alongside ad spend and ACoS versus last week and prompts to dig deeper with your AI.
