Avoiding Duplicate or Overly Broad Match Types in Amazon PPC
← Back to Step-by-Step Guide to Cleaning Up Your Amazon PPC Campaigns
Quick answer
Duplicate or overly broad match types in Amazon PPC are common pitfalls that can waste advertising budget and lead to poor campaign performance. Managing match types with care ensures your ads target relevant searches without cross-over, overlap, or unnecessary spend. Regular checks and disciplined keyword strategies keep campaigns efficient and transparent.
Maintaining a clean structure in your Amazon PPC campaigns requires vigilance about match types. Overlapping or duplicated match types can cause auction cannibalization, wasted spend, and make it harder to optimize your ads effectively.
Understanding Match Types and Duplicates
Amazon PPC uses three primary match types: broad, phrase, and exact. Duplicating the same keyword across campaigns or ad groups with multiple match types—without clear strategy—often leads to the same product competing against itself for similar search queries. This muddies reporting and inflates costs.
- Broad Match: Casts the widest net; can trigger ads for loosely related terms.
- Phrase Match: More focused, but can still match variations.
- Exact Match: Triggers ads only when the exact search term is used.
Effective Approaches to Cleanup
To prevent inefficiencies, map out your keywords across all campaigns and keep a clear structure—assign each keyword a purpose and avoid redundant placements. Negative keywords can be invaluable: exclude terms at the campaign or ad group level to prevent internal competition.
Use auditing tools like the Amazon Negative Keyword Tool by Todoza to analyze active search terms and identify where overlap or budget-draining queries occur. These insights support decision-making about which match types to prioritize and where to apply negatives.
When Match Type Overlap Matters Most
This issue is most pressing for brands with multiple campaigns targeting similar keywords, large catalogs, or those routinely testing new keyword strategies. Unchecked overlap can quietly drain budget and obscure performance data, making it particularly critical during heavy sales periods or when scaling campaigns.
