The 3 Keyword Match Types of Amazon Advertising

What are keyword match types?

Match types allow you control over what customer search queries will match to the keywords in your manual targeting Amazon advertising campaigns. It’s nearly impossible to account for all the various phrases a customer could use when searching for a product on Amazon, and keyword match types exist to help you combat that challenge.

Using match types to your advantage will help you find new customers, discover the best keywords to target to meet your goals, and eliminate wasted spend.

The three keyword match types

The three keyword match types are Exact, Phrase, and Broad. But before discussing match types, it’s important to be aware of some rules and definitions.

Close variations refers to plural or singular forms of a word.

  • Ex: “Shoes” is considered a close variation of “shoe.”

Misspellings are not accounted for across any match types.

  • Ex: If a customer searches for “vitamns”, an ad that is only associated with “vitamins” will not serve.
  • It is a best practice to add common misspellings as keywords.

**Ignored words: **The following words are ignored: “the,” “of,” “when,” “and,” “if” for all match types.

Exact match

Description: The search query must be the exact keyword or phrase, or very close variations. The search query needs to be in the same order and cannot contain additional words.


Exact match keyword: cycling helmet

Customer Search Term Eligibility
cycling helmet Eligible
cycling helmets Eligible
bicycling helmet Ineligible
helmet for cycling Ineligible
cycling hemet Ineligible (misspelling)

Phrase match

Description: The exact phrase, or close variations, must be included and be in the same order as the keyword term. The search query may contain words before or after the keyword term.


Phrase match keyword: meat smoker

Customer Search Term Eligibility
best meat smoker Eligible
brands of meat smokers Eligible
smokers for meat Ineligible
beef smoker Ineligible

Broad match

Description: The search query must contain all the keyword terms, or close variations. Words can be in any order and contain additional words.


Broad match keyword: kids unicorn toys

Customer Search Term Eligibility
unicorn toys for kids Eligible
kids plush unicorn toy Eligible
kids toys Ineligible
unicorn toys Ineligible

Note: If you set multiple match types for the same keyword, and your match types have different bids, then the match type with the highest bid will be used for any matching shopping query. It’s often best to bid highest on exact keywords, less for phrase and have the broad match variation get the lowest bid.

Negative keywords

Negative keywords allow you additional control over the customer search queries that can trigger your ads. These are necessary to utilize when you’ve added phrase and especially broad match keywords to your advertising campaigns.

Negative keyword match types:

  • Negative exact: Ads don’t show on search queries that contain the exact phrase or close variation.
  • Negative phrase: Ads don’t show on search queries that contain the complete phrase or close variations.


Broad match keyword: t shirts

Negative phrase match keyword: men

Customer Search Term Eligibility
women’s t shirts Eligible
t shirts for men Ineligible
men’s t shirts Ineligible

Use negative keywords to eliminate the possibility of your ad appearing for an irrelevant or otherwise unwanted query while remaining open to variations of a core keyword. You can also use the search terms report to see what search queries triggered your ads and identify search phrases that you want to block using negative keywords.

What keyword match types should I use?

There are varied opinions on what keyword match types to use and why. It really all comes down to your comfort level with advertising and your advertising goals.
