The Amazon PPC waste audit: what to negate, what to leave alone
Short answer: "zero orders" is not, by itself, a reason to negate a search term. It's a reason to check three things first: whether the click volume is high enough to trust the signal, whether the wasted spend came from a keyword or a completely different targeting mechanism you can't negate with a keyword, and whether the term overlaps something that's actually converting for you.
Step 1 — Is the sample big enough to trust?
A term with 1 click and 0 orders tells you almost nothing — that's just how conversion rates work at small numbers. A reasonable floor is somewhere around 8+ clicks with zero orders, combined with a minimum wasted-spend threshold (filtering out anything under roughly ₹20 in spend) — otherwise you'll spend your audit time chasing statistical noise instead of real leaks.
Step 2 — What actually generated this "search term"?
This is the step most PPC advice skips, and it's the one that wastes the most seller time. Amazon logs a "search term" for every click regardless of what mechanism produced it — but only some of those mechanisms respond to a negative keyword.
Genuine keyword
A shopper actually typed this. → Add as a negative exact keyword. This is the only case a negative keyword directly fixes.
Product target
The ad ran on a competitor's product page (Product Targeting, or an Auto campaign's substitute/complement match on an ASIN). → A negative keyword does nothing here. Add a negative PRODUCT TARGET, or pause the target.
Category target
The ad ran via a category-level target, not a keyword. → Tighten or pause the category target. Adding the logged term as a negative keyword can also suppress winners that happen to share words with it.
Auto loose/close match
Auto campaign matched on a related text query. → Usually safe to negate as a keyword, same as a genuine keyword match.
Look at the campaign's targeting type and the raw target value — not just the search-term column — to tell these apart. If the target value is a 10-character ASIN, you're looking at a product target no matter what the "search term" says.
Step 3 — Does it overlap a winner?
Before negating, check whether the wasted term contains — or is contained in — a term that IS converting for you. Negating "bubble wrap" as an exact keyword because it never converts, while "bubble wrap roll" is a top earner on broad match, can quietly cut off the match type that's actually working. When there's overlap, narrow the bid or match type instead of negating outright.
SellerBlaze's PPC optimizer runs exactly this three-step check automatically — classifying target type, checking for winner overlap, and only ever proposing the correct action (negative keyword, negative product target, or tighten) before you click anything.

Frequently asked questions
How many clicks with zero orders before I should negate a search term?+
There's no universal number, but a term needs enough clicks that zero orders is actually a signal rather than noise — 8 clicks with nothing is meaningful; 1 or 2 clicks with nothing usually isn't. Pair it with a minimum spend filter too (a few rupees of wasted spend isn't worth acting on), otherwise you'll churn your negative list chasing statistical noise.
Why would a negative keyword not stop a wasted search term?+
Because "search term" and "keyword" aren't the same thing. If the ad ran because of a Product Targeting or Auto-campaign product/category match (you're bidding on a competitor ASIN or a category, not a text keyword), adding a negative keyword does nothing — the match happened through a completely different targeting mechanism. You have to add a negative product target or tighten the category target instead.
How do I tell if a wasted search term is a keyword or a product target?+
Check the campaign's targeting type and the raw target value, not just the "search term" column. If the target value is itself a 10-character ASIN, or the campaign is an Auto campaign matching on substitutes/complements, you're looking at a product target — the "search term" Amazon logs is really the competitor's product page, not something a shopper typed.
Should I ever negate a term that has zero orders but a lot of clicks?+
Not automatically — check first whether it overlaps a term that IS converting for you. Negating "bubble wrap" as an exact keyword because it hasn't converted, when "bubble wrap roll" is your best seller, can suppress the match that's actually making you money on broad/phrase types. Check for overlap with your winners before you negate.
