What is a negative keyword on Amazon?

A negative keyword tells Amazon not to show your ad against searches containing that term. Used correctly, negatives stop wasted spend on irrelevant traffic without hurting your converting traffic.

How often should I add negative keywords?

Weekly minimum. Amazon delivers new search-term data continuously. Sellers who only review monthly bleed thousands of dollars per year on terms that never convert. AIAdKing automates the workflow continuously.

Negative exact or negative phrase?

Negative exact is safest — it blocks only the exact phrase. Negative phrase blocks anything containing the phrase. Use exact when in doubt; use phrase only after careful review.

Can AI find negative keywords better than a human?

AI is not necessarily smarter, but it never tires and never skips a week. AIAdKing scans search-term data continuously, applies your rules (clicks, spend, ACoS thresholds), and adds negatives with a logged reason.

How to find negative keywords for Amazon ads automatically

Manual workflow takes about 45 minutes per week per account. Or automate it: AIAdKing scans search-term data continuously and adds negatives with a logged reason for each one.

Short answer: negative keywords stop your ads from appearing against irrelevant searches. Manual workflow: pull search-term report, filter zero-conversion clicks and high-cost irrelevants, add as negative exact. Repeat weekly. Or automate continuously with AIAdKing.

The manual workflow

Pull the search-term report from the Amazon Ads console for the last 60 days.
Filter zero-conversion clicks: 10+ clicks, zero orders. These are paying-for-nothing.
Filter high-cost irrelevants: spend more than 2x your target CPA. These are bleeding.
Add as negative exact in the campaign or ad group that spent on them.
Repeat weekly.

Why automation matters

Amazon delivers new search-term data daily. Most sellers review monthly at best. In a typical 30-day window between manual sweeps, ~5–15% of ad spend goes to terms that will never convert. That is $500–$1,500 per month wasted on a $10K budget.

How AIAdKing automates it

AIAdKing scans search-term data continuously. Each negative addition has a logged reason: "12 clicks, 0 conversions, $4.20 spent on irrelevant search term 'cheap [your product]'." You can review the log, approve in bulk, or let the AI run autonomously inside your guardrails.

During the 14-day free trial, this runs in shadow mode so you see every proposed negative without anything touching your account.

Stop bleeding on irrelevant clicks.
