Negative Keywords
Negative keywords are search terms you exclude from your Amazon PPC campaigns to prevent ads from showing on irrelevant queries. When a shopper searches for a negative keyword, your ad is blocked from appearing. Properly managed negative keyword lists are one of the most direct levers for improving PPC efficiency.
Why it matters for Amazon sellers
Every irrelevant click is wasted money. Without negative keyword management, your ads show up for searches that will never convert — wrong product type, wrong brand intent, wrong price tier. A single broad match campaign can easily leak 20 to 40 percent of its budget to unqualified traffic if negatives are not actively maintained. Aggressive negative keyword hygiene is one of the fastest ways to cut ad waste without touching bids. There are two common failure modes. The first is not doing it at all — search term reports go unreviewed for weeks or months, and budget drains to irrelevant queries. The second is over-negating — adding so many exact-match negatives that you starve the campaign of qualified impressions. Modern AI bid systems can mine search term reports daily, evaluate conversion patterns at the query level, and add negatives before waste compounds. Most sellers do this reactively and quarterly; the best sellers automate it continuously.
How Profasee handles this
Marko continuously analyzes search term reports across every active campaign, identifies wasted-spend patterns, and adds negative keywords before budget leaks grow. It is the tedious, high-frequency optimization work most sellers skip because they do not have the bandwidth — and exactly the kind of repetitive expert judgment that benefits most from an always-on AI agent.

Frequently asked questions
What are negative keywords in Amazon PPC?
Negative keywords are search terms you exclude from your PPC campaigns. When a shopper searches for a negative keyword, your ad will not show. This prevents wasted ad spend on clicks from people who are not looking for your product.
How often should I update negative keywords?
At minimum, weekly. High-spend accounts benefit from daily search term analysis. The longer you wait, the more budget leaks to irrelevant searches. AI tools can monitor and negate continuously, which is far more efficient than manual reviews.
What is the difference between negative exact and negative phrase?
Negative exact blocks only that specific query; negative phrase blocks any query containing that phrase. Use negative exact for specific irrelevant terms ('kids' on an adult product), negative phrase for broader patterns ('cheap' if you are premium-priced). Both belong in a clean negative keyword strategy.
