Which match type is best for Amazon PPC?

There is no single 'best' match type — each one has its place in a well-thought-out strategy. Broad match is great for keyword discovery, phrase match for targeted reach on relevant traffic, and exact match for proven top performers. Combining all three match types usually delivers the best results.

Should I start with broad or exact match?

For new products, it's best to start with broad match (and an auto campaign) to discover relevant search terms. Once you have enough data (at least 2-4 weeks, ideally 50+ clicks per keyword), you move your best performers into exact match campaigns. For established products with known top keywords, you can also start directly with exact match.

How does phrase match differ from broad match?

With broad match, Amazon can serve your ad for any search term that is thematically related to your keyword — including synonyms and related terms. With phrase match, the core phrase of your keyword has to appear in the search term, in the same order. Phrase match therefore gives you more control than broad, but less reach.

Do I need all three match types at the same time?

Not necessarily, but a combination makes sense in most cases. At a minimum, you should use broad or auto for keyword discovery and exact for your top performers. Phrase match as an intermediate stage is optional, but it helps filter relevant search terms before you promote them to exact.

Why does my exact match keyword show up for the wrong search terms?

Amazon does not interpret 'exact match' literally, letter for letter. Very close variants like plurals, typos and tight synonyms still get triggered. That is normal and usually makes sense. If you do see genuinely irrelevant search terms, add them as negative keywords.

Amazon PPC Match Types in Practice – Combining Broad, Phrase and Exact

Last updated: February 4, 2025

Reading time: approx. 7 minutes

Broad, phrase or exact match — which match type should you choose? Amazon sellers ask themselves this question every day. The answer: all three — but combined strategically. Because every match type has its place in the keyword funnel.

In this article I'll show you how the different Amazon PPC match types work, when to use each one, and how to connect them into a profitable overall keyword strategy. With the right setup, you control who sees your ads — and who doesn't.

What are match types? The basics

Match types determine which search queries your Amazon ads are served on. They are the steering wheel of your keyword targeting strategy — they let you control the balance between reach and relevance.

The three match types at a glance:

BroadWidest reach, least control — Amazon also matches synonyms and related terms

PhraseMedium reach, more control — the core phrase has to appear in the search term

ExactLowest reach, maximum control — only the search term itself (and close variants)

The fundamental trade-off is always the same: more reach means less control — and vice versa. Broad match brings you plenty of impressions, but also irrelevant clicks. Exact match brings you highly relevant traffic, but possibly too little of it.

Match type	Reach	Control	Typical CPC
Broad match	High	Low	Low to medium
Phrase match	Medium	Medium	Medium
Exact match	Low	High	High (more competition)

Broad match: maximum reach, minimal control

With broad match, you let Amazon serve your ad for any search query that is thematically related to your keyword. That includes synonyms, related terms and even spelling variants.

Broad match example:

Keyword: "coffee machine"

Possible search terms:

buy coffee machine
espresso machine
automatic coffee maker
best filter coffee machine
bean to cup coffee machine review

When to use broad match?

Keyword discovery: find new search terms you hadn't thought of

Product launch: build reach and data quickly

Niche products: when the search volume for exact match is too low

Watch out: typical broad match traps

Without negative keywords, your budget quickly leaks into irrelevant searches
Higher ACoS values are normal — broad is for discovery, not for profitability
Regular search term analysis is mandatory, not optional

Phrase match: the happy medium

Phrase match is the compromise between reach and control. Your ad is served when the search term contains your keyword phrase in the same order — but words before or after it are allowed.

Phrase match example:

Keyword: "bluetooth headphones"

Will be matched:

bluetooth headphones wireless
best bluetooth headphones
bluetooth headphones sport waterproof

Will NOT be matched:

headphones bluetooth (wrong order)
wireless earbuds (synonym)
wired headphones (no Bluetooth)

When to use phrase match?

Targeted expansion: find new long-tail variants of a core keyword

Intermediate stage: validate keywords from broad before they move into exact

Brand protection: protect your brand + product category

Phrase match is like a sieve with medium-sized holes: it lets enough through to make interesting catches, but it already filters out the coarsest junk.

Exact match: precision at the cost of reach

Exact match sounds like "exact," but it isn't literal, letter for letter. Even with exact match, Amazon also matches very close variants such as plurals, typos and acronyms. Still, exact match offers the highest control of all the match types.

Exact match example:

Keyword: "yoga mat"

Will be matched:

yoga mat
yogamat (spelling variant)
yoga mats (plural)

Will NOT be matched:

non-slip yoga mat
best yoga mat
exercise mat

When to use exact match?

Proven top performers: keywords with a demonstrated conversion rate

Budget optimization: maximum efficiency on a limited budget

Aggressive bids: on keywords where you want the pole position

Brand defense: your own brand name as an exact match

Fact: exact match keywords have, on average, a 15-30% higher conversion rate than broad match keywords — but also a 20-40% higher CPC due to the stronger competition.

How to combine match types the right way

The real art isn't in choosing a single match type, but in the strategic combination of all three. Here is the proven structure we use at HORAiZON for our clients:

The keyword pyramid

Broad match + auto campaign (discovery)

Find new keywords. Lower bids, broad coverage. Goal: identify search terms that convert.

Phrase match (validation)

Test promising keywords from the discovery phase. Medium bids, focused reach.

Exact match (performance)

Scale proven top performers. Higher bids, maximum control and profitability.

The keyword promotion workflow

Keywords flow through your structure — from discovery to optimization:

Step	Action	Trigger
1. Discovery	Keyword in auto/broad generates conversions	Min. 2-3 conversions
2. Validation	Promote keyword to phrase match	ACoS below target ACoS
3. Performance	Promote keyword to exact match	Stable ACoS + min. 50 clicks
4. Champion	Its own single keyword campaign	$500+ revenue/month

A match type strategy is like a funnel: at the top you pour in a lot with broad, in the middle phrase and exact filter out what's relevant, and at the bottom only the real gold nuggets come through.

Negative keywords: the underrated tool

A match type strategy is only as good as the negative keywords that go with it. Negative keywords prevent your ads from being served on irrelevant or already-covered search terms.

Two kinds of negative keywords

Negative phrase

Blocks all search terms that contain the phrase.

Example: "free" as a negative phrase blocks "free yoga mat", "free shipping yoga mat" etc.

Negative exact

Blocks only the exact search term.

Example: "free yoga mat" as a negative exact blocks only this one term.

Negative keywords in practice

Important: avoid cannibalization!

When you move a keyword from broad to exact, add it in the broad campaign as a negative exact. Otherwise your own campaigns compete against each other:

Exact keywords → as negative exact in broad/phrase campaigns
Phrase keywords → as negative phrase in broad campaigns
Top performers → as negative exact in auto campaigns

Typical negative keywords

Generic exclusions

free, gratis
used, second hand
repair, spare parts
instructions, tutorial, how to

Competitor brands

Competitor brand names
Other product lines
B2B terms (when you're B2C)
Regional exclusions

Conclusion: your match type strategy for 2025

Match types are not an either-or decision. The most successful Amazon sellers use all three match types together strategically — with a clear role for each:

Your main takeaways:

Broad = discovery: find new keywords with low bids and broad coverage
Phrase = validation: test promising keywords with controlled reach
Exact = performance: scale proven winners with maximum control
Negative keywords: the foundation of every match type strategy — without them your budget evaporates
Continuous process: move keywords through your structure regularly — from discovery to performance

The difference between average and successful Amazon sellers often comes down to discipline in keyword maintenance. Analyze your search term report at least weekly, promote performers into higher match types, and consistently expand your negative keywords.
