Phrase Match

Phrase match is the middle Amazon PPC keyword match type. It triggers when the shopper's query contains the keyword's tokens in the same order, with additional words allowed before or after. Useful where word order carries semantic meaning.

Phrase match sits between Broad and Exact in Amazon's match-type hierarchy. A phrase-match keyword triggers when the shopper's search query contains the keyword's tokens in the same order, with additional words allowed before and after (and the usual close-variant tolerance for plurals and typos).

Bid keyword: stainless steel water bottle. Will match:

  • best stainless steel water bottle 1L (extras around)
  • stainless steel water bottles for kids (extras after, plural variant)

Will not match:

  • water bottle stainless steel (order changed)
  • steel water bottle (token removed)

Where phrase actually earns its keep

Most modern Amazon accounts run a heavy broad/exact split with phrase as a thin bridge layer. The cases where phrase outperforms either alternative:

  1. Compound keywords where word order carries semantic meaning. women's running shoes ≠ shoes for women running. Phrase match preserves the order constraint without paying the broad-match expansion premium.
  2. Brand + product modifier combinations. nike air max should not match max nike air (which is gibberish). Phrase keeps the brand-modifier-product structure intact.
  3. Long-tail intent capture without exact restriction. wireless earbuds for sleeping as phrase captures best wireless earbuds for sleeping on flights without the broad-match risk of matching wireless headphones for music.

CVR profile

Phrase-match CVR typically lands at 70–85% of the equivalent exact-match CVR — closer to exact than to broad. The bid follows the same math:

Phrase Bid = ASP × CVR_phrase × Target ACOS  ≈  70–80% of exact bid

When phrase is the wrong tool

Two cases where running phrase adds operational complexity without measurable upside:

  • Single-token keywords. headphones as phrase match is functionally identical to headphones as broad match — the order constraint is vacuous when there's only one token.
  • Categories where Amazon's close-variant matching is loose. In some categories the platform's relevance model effectively expands phrase match into broad match, defeating the purpose.

For most accounts, the rule of thumb is: skip phrase by default, add it when a specific compound keyword needs the order constraint.

Common mistakes

  • Running phrase as the primary match type. Some templates default to phrase-only campaigns. The result is mid-range CVR with neither the discovery breadth of broad nor the precision of exact.
  • Bidding the same on phrase and exact. Phrase CVR is lower; the bid should be ~20–30% lower.
  • No negative-exact on the phrase parent for terms harvested into exact. Same leak as broad — the phrase parent keeps bidding on the harvested winner.
  • Mixing phrase keywords into exact ad groups. Destroys ad-group CVR consistency. Keep one match type per ad group.

Match Type (Broad, Phrase, Exact)
Match type controls how strictly an Amazon PPC keyword must align with the shopper's search query for the ad to enter the auction. The three modes — Broad, Phrase, and Exact — define the discovery-to-profit pipeline of the account.
Broad Match
Broad match is the loosest of the three Amazon PPC keyword match types. It triggers on any shopper query containing the keyword's tokens in any order, plus synonyms, plurals, and related terms — making it the discovery engine of the account.
Exact Match
Exact match is the tightest Amazon PPC keyword match type. It triggers only when the shopper's query matches the keyword exactly (with allowance for plurals and close variants). It is the profit centre of the account — 70–80% of healthy ad spend flows through exact-match campaigns.
Negative Keyword
A negative keyword is a search term you've decided not to bid on. Negatives are the cleanup tool of the harvest loop and the primary way to prevent broad-match campaigns from leaking spend on irrelevant or already-harvested terms.
Keyword (Amazon PPC)
A keyword is a search term an advertiser bids on inside Amazon PPC. It is the bid handle; the actual user behaviour is the search term. The keyword harvest loop is the workflow that turns search terms into keywords.
