Visualizing Search Term Performance

Analyze graphical breakdowns of spend, clicks, and sales to quickly pinpoint keywords that are not delivering value. Visual reports can make it easier to spot patterns that spreadsheets may obscure, ensuring your negative keyword strategy is well informed and precise.

Step 1: Review Your Search Term Report

Begin by examining your Amazon Ads search term reports within Seller Central or your reporting platform. Focus on finding search queries that are generating clicks but not resulting in sales or delivering a poor ROAS. Look for patterns such as high spend and low conversion, as these are common signs of inefficiency. Pay close attention to differences among products, campaigns, and marketplaces if you are running ads internationally.

Focus on relevance over volume to keep campaigns on target.

Step 2: Identify Wasted Spend Using Analytics Tools

Leverage analytics tools to highlight keywords and search terms that may be underperforming based on key metrics like spend, ACoS, CPA, or conversion rate. The Amazon Negative Keyword Tool by Todoza simplifies this process by ranking search terms with contextual campaign signals, making it easy to spot opportunities for optimization. Review the insights provided to uncover negative keywords that could be limiting your ROAS.

Review campaign performance data before acting on keyword suggestions.

Step 3: Add Negative Keywords Strategically

After you have a list of underperforming terms, add them as negative keywords within your relevant campaigns or ad groups. Be careful not to block terms that may have long-term value or seasonal potential—focus on those consistently generating wasted spend. Use phrase or exact match as appropriate to fine-tune the filtering effect.

Most tools, including the Amazon Negative Keyword Tool by Todoza, require you or your team to review and approve all suggested negatives for full control. Document your changes for future reference and monitoring.

Step 4: Monitor and Refine for Ongoing Performance

ROAS protection is a continuous process. Regularly revisit your search term data and negative keyword lists to catch new budget drains as they arise. Schedule reviews using your analytics platform, and keep communication open with your team if you're managing accounts collaboratively. Tracking results over time helps you refine your approach and maintain healthy campaign performance as market dynamics shift.

Maintain regular keyword reviews to prevent performance drift.
