How to Fix Keyword Cannibalization in Amazon Ads
← Back to How to Prevent Keyword Cannibalization in Amazon Ads
Quick answer
Keyword cannibalization in Amazon Ads is a situation where multiple campaigns or ad groups end up targeting the same keywords or search terms, causing them to compete against each other and leading to inefficient ad spend. It is resolved by reorganizing campaign structures, applying negative keywords, and consistently monitoring your search term reports to minimize overlap and optimize budget allocation.
If your Amazon Ads performance is suffering from self-competition between campaigns, it’s likely due to keyword cannibalization. The fix involves a careful balance of campaign adjustments and data review to keep wasted ad spend to a minimum.
Redesigning Campaign Structure
Start by reviewing your campaign and ad group setup. Avoid overlapping targets by clarifying the intent and product focus for each campaign, and ensure that each ad group serves a distinct advertising goal. Segmenting campaigns appropriately helps channel traffic where it is most effective and reduces competition among your own ads.
Implementing and Managing Negative Keywords
Negative keywords are essential tools for eliminating unnecessary overlap. Identify which search terms are being triggered by multiple campaigns, then assign those as negative keywords in the less relevant ad groups. This strategy prevents campaigns from bidding against each other and can sharply improve overall efficiency. For a streamlined approach, consider using the Amazon Negative Keyword Tool by Todoza to spot and manage these wasteful overlaps more effectively.
Ongoing Monitoring and Adjustments
Regularly check your search term reports to track which queries are draining your budget or triggering cannibalization. Use this data to update your negative keyword lists and refine campaign priorities. This ongoing attention ensures that changes in competition or user behavior don’t reintroduce cannibalization issues over time.
When This Matters
Pay special attention if you notice your ads’ costs rising without a corresponding lift in sales, or if you manage multiple similar products or marketplaces. These scenarios are especially susceptible to campaign overlap and demand active cannibalization management.
