Amazon PPC Match Types: The Complete Guide to Broad, Phrase, and Exact Match in 2026

A few months ago, a kitchen-gadget seller named Marcus walked into a 1-on-1 review with his ad spend bleeding. He had a single Sponsored Products campaign with 80 keywords. Every single keyword was set to broad match. His ACoS was 62%. His TACoS was climbing. He was spending $4,300 a month and watching his margins evaporate.

The problem was not his bids. It was not his listing. It was not even his product. The problem was that broad match was showing his “stainless steel garlic press” ad to people searching for “garlic seeds,” “press release,” and “stainless steel sink.” Every irrelevant click cost him $0.70 to $1.20 with no chance of a sale.

We restructured his account around proper match type usage. Inside three weeks, his ACoS dropped to 28%, his ad-attributed sales went up 19%, and his wasted spend on irrelevant search terms fell by more than 60%. The fix was not magic. It was just understanding what Amazon's three keyword match types actually do, and using each one for what it is good at.

Match types are the most misunderstood part of Amazon PPC. Sellers either ignore them entirely or pick one and run everything through it. Both approaches leak money. This guide covers everything you need to know about Amazon PPC match types in 2026: how each one works, when to use it, what to bid, and how to combine all three into a structure that compounds in your favor over time.

What Are Amazon PPC Match Types?

A match type tells Amazon how closely a shopper's search has to match your keyword before your ad is allowed to show. You set the match type when you add a keyword to a manual campaign. Amazon offers three options for keyword targeting in Sponsored Products: broad match, phrase match, and exact match.

Each match type makes a different tradeoff between reach and relevance. Broad match maximizes reach. Exact match maximizes relevance. Phrase match sits in the middle. The match type also affects how much Amazon will charge you per click and how often your bid wins the auction.

Match types only apply to keyword targeting. Product targeting (ASIN and category targeting) does not use match types. Sponsored Brands and Sponsored Display also support match types, but with slightly different rules. This guide focuses on Sponsored Products, where match type decisions have the biggest impact on most sellers' budgets.

If you are still getting comfortable with how Amazon advertising works overall, start with our beginner's guide to Amazon PPC, then come back here.

Broad Match: Maximum Reach, Minimum Control

Broad match is the loosest match type. Your ad is eligible to show on searches that include your keyword, related keywords, plurals, synonyms, misspellings, abbreviations, and even searches that loosely relate to the meaning of your keyword.

If you bid on the broad match keyword “running shoes,” your ad can show on:

• “running shoes” (exact)
• “men's running shoes”
• “shoes for running”
• “jogging sneakers”
• “trail runners”
• “athletic footwear”

In recent years, Amazon also rolled out “broad match modifiers” that let you append terms with a plus sign to require their inclusion. You can also use broad match with negatives to carve out the irrelevant matches. Even so, broad match still casts a wide net by design.

When Broad Match Wins

Broad match is your discovery tool. Use it when you want Amazon to surface search terms you would never have thought of yourself. The whole point is to let the algorithm match your ad to queries that are loosely related, then mine those queries later for the gems.

Broad match works best when:

• You are launching a new product and need to find which search terms convert before you commit budget to specific keywords.
• You are running a discovery campaign specifically built to harvest new keywords for your exact match campaigns.
• You have strong negative keyword hygiene and trust your account to block junk before it racks up clicks.
• Your product has a clear use case but lives in a category with many search variations (think kitchen gadgets, hobby supplies, parenting items).

Broad Match Risks

The same flexibility that makes broad match useful is also what makes it dangerous. Without negative keywords, broad match will absolutely show your ad on searches that have nothing to do with your product. We have seen broad match keywords trigger on searches where the only connection was a single common word.

Common broad match traps:

• A “yoga mat” broad keyword shows on “yoga teacher training,” “yoga clothes,” and “mat board for picture frames.”
• A “wireless headphones” broad keyword shows on “wireless charger,” “headphone jack adapter,” and “Bluetooth speaker.”
• A “garlic press” broad keyword shows on “garlic powder,” “press conference,” and “stainless steel sink.”

Bid lower on broad match than you would on phrase or exact. A reasonable starting point is 50% to 70% of your exact match bid for the same keyword. The math is simple: broad match drives more impressions but lower-quality clicks, so you need a lower cost per click to make it worth the volume.

Phrase Match: The Useful Middle Ground

Phrase match is the compromise. Your ad shows on searches that contain your keyword as a phrase, in the order you specified, with words allowed before or after but not in the middle.

If you bid on the phrase match keyword “running shoes,” your ad can show on:

• “running shoes” (exact)
• “men's running shoes”
• “running shoes for women”
• “best running shoes 2026”
• “running shoes size 10”

But your ad will not show on:

• “shoes for running” (word order changed)
• “running and walking shoes” (extra word in the middle)
• “trail runners” (synonym, not the actual phrase)

Phrase match preserves intent better than broad. If a shopper types “running shoes for flat feet,” they are clearly looking for running shoes, just with a specific need. Phrase match captures that variation. If they type “shoes that look good for running errands,” phrase match correctly excludes them.

When Phrase Match Wins

Phrase match is your workhorse for capturing meaningful variations of a target keyword without the noise of broad match. Use it when:

• You have validated keywords that convert and want to capture long-tail variations of them.
• You are scaling a successful exact match keyword and want to expand without going fully broad.
• Your category has predictable search modifiers (sizes, colors, use cases, materials) that get appended to root keywords.
• You want better cost-per-click discipline than broad match provides while still capturing more searches than exact alone.

Phrase Match Pitfalls

Phrase match is not bulletproof. Sellers sometimes assume it only matches “their phrase plus extra words,” then get confused when Amazon shows their ad for a search with their words in a different syntactic context. For example, “iPhone case” as a phrase match might trigger on “iPhone case removal tool,” technically the phrase is contained, even if the search intent is completely different.

Build a strong negative keyword list to clean up phrase match the same way you would for broad. The good news is phrase match needs less negative keyword maintenance than broad, because the matches are already constrained.

A reasonable starting bid for phrase match is 75% to 90% of your exact match bid for the same keyword. The match quality is closer to exact than to broad, so the bid should reflect that.

Exact Match: Maximum Control, Maximum Conversion

Exact match does what it sounds like. Your ad only shows on searches that exactly match your keyword (or are very close variants, plurals, misspellings, and minor article changes like “the” or “a”).

If you bid on the exact match keyword “running shoes,” your ad can show on:

• “running shoes”
• “running shoe” (singular variant)
• “runnnig shoes” (common misspelling)

Your ad will not show on:

• “men's running shoes”
• “best running shoes”
• “running shoes for women”

That tight constraint is a feature, not a bug. Exact match gives you the highest level of control over what your ad spend goes toward. Every impression is on a search query you specifically chose to bid on.

When Exact Match Wins

Exact match is where your most profitable budget goes. Use it for:

• Proven keywords with strong conversion history. Once a search term has shown it converts, lock it down in exact match and bid aggressively to win the placement.
• Branded terms. If shoppers search for your brand name plus a product type, you should own that traffic at a high bid, low cost per click, and very high conversion rate.
• High-intent commercial keywords. “Buy [product],” “[product] review,” “[product] [year]” all signal someone close to a purchase decision.
• Keywords where the cost-per-click would be punitive in broader match types. If a single irrelevant click would erase your margin on three sales, exact match is your protection.

Exact Match Tradeoffs

The downside of exact match is that you only show up for the exact searches you target. If a shopper types a slight variation you did not anticipate, you miss the impression. That is why exact match works best as part of a combined match type structure rather than as a standalone strategy.

Bid most aggressively on exact match. These are the keywords you have proven convert, so paying more per click to win the placement is usually worth it. Exact match keywords often have 20% to 50% higher conversion rates than the same keyword in broad or phrase match.

The Keyword Waterfall: How to Combine All Three Match Types

Smart Amazon sellers do not pick one match type. They use all three in a structured pipeline that we call the keyword waterfall.

Here is how the waterfall works:

1. Discovery tier (auto + broad): An auto campaign and a broad match campaign run with low bids and broad targeting. Their job is to surface new search terms you have not thought of yet. They are not built to be wildly profitable. They are built to find data.
2. Validation tier (phrase): Search terms that convert in the discovery tier get added as phrase match keywords in a separate campaign. Phrase match captures variations and tests the keyword's performance with tighter constraints.
3. Performance tier (exact): Phrase match keywords that consistently convert at acceptable ACoS get promoted to exact match in a third campaign. Exact match is where you bid most aggressively and where most of your profitable ad sales come from.
4. Negative loop: At every tier, search terms that do not convert get added as negative exact or negative phrase keywords in the upstream campaigns. This stops the discovery tier from re-spending budget on dead-end queries you have already disqualified.

This structure separates discovery from performance. Your discovery campaigns can run with looser controls because their job is to find new keywords cheap. Your performance campaigns can bid aggressively because every keyword in them has earned its placement through prior data.

If you want a deeper walkthrough of how to actually build this campaign structure in Seller Central, see our Amazon PPC campaign structure guide.

Match Type Bidding Strategy

Bids should reflect match quality. Here is a workable starting framework once a keyword has earned its place at each tier:

• Exact match: 100% of your target bid (the bid that hits your target ACoS based on your conversion data)
• Phrase match: 75% to 90% of your exact bid
• Broad match: 50% to 70% of your exact bid

These ratios are starting points. The right ratio for your account depends on conversion rate differences across match types and your category's competitive intensity. The actual bid that hits your target ACoS comes from this formula:

Target Bid = Average Order Value x Conversion Rate x Target ACoS

If your average order value is $35, your conversion rate on a keyword is 12%, and your target ACoS is 25%, your bid math is: $35 x 0.12 x 0.25 = $1.05.

Run that calculation for each match type using its own conversion rate. Exact match almost always converts higher than broad, so its target bid will be higher. For more on bid setting, see our Amazon PPC bid strategy guide.

A Real Example: How a Pet Supplies Seller Used Match Types

A pet supplies seller named Priya was selling a slow-feeder dog bowl. She had been running a single broad match campaign with the keyword “slow feeder dog bowl” and 14 related broad match keywords. Her ACoS was 41% and she was tired of pulling search term reports every weekend to add negatives.

We rebuilt her campaigns into a three-tier structure:

• Discovery campaign: 1 auto campaign and 1 broad match campaign, both running with 50% of her old bids. Daily budget of $25 each.
• Phrase campaign: Empty at first. Built up over the following four weeks with phrase match keywords harvested from the discovery campaigns.
• Exact campaign: Empty at first. Built up over six to eight weeks with exact match keywords promoted from the phrase campaign.

By week four, the discovery campaigns had surfaced 23 new search terms she had never considered. Eleven of them converted. Those eleven became phrase match keywords with bids set to 80% of the calculated target bid.

By week eight, six phrase match keywords had earned their way to exact match. Those exact match keywords ended up driving 58% of her total ad sales at a 19% ACoS. Her overall account ACoS dropped from 41% to 24%, and her total ad-attributed sales were up 32% on roughly the same total spend.

The match type structure did the heavy lifting. The keyword discovery happened on the cheap broad match campaigns. The high-margin sales happened on the focused exact match campaign. Each tier did its job, and the waterfall kept feeding new winners up the chain.

Common Match Type Mistakes to Avoid

After auditing hundreds of seller accounts, here are the patterns we see hurting match type performance most often:

• Running everything in broad match with no negatives. This is the single biggest budget drain we see. Without negative keywords, broad match will always find a way to spend on irrelevant queries. If you use broad match, you must have a routine for adding negatives.
• Using identical bids across all match types. Match types should not share bids. Exact match earns a higher bid because it converts better. Broad match warrants a lower bid because of the click quality. Equal bids waste exact placements and overpay for broad clicks.
• Mixing match types in the same campaign. Keep each match type in its own campaign or at minimum its own ad group. When you mix them, your reports get muddy and you cannot tell which match type is actually driving conversions versus eating budget.
• Forgetting the negative loop. When a search term converts in your broad campaign, you should add it as a negative in that campaign and add it positively in your phrase or exact campaign. Without this loop, the search term keeps competing with itself and your bids get scrambled.
• Treating exact match as plug-and-play. Adding a keyword as exact match does not guarantee it will convert. If a keyword has no conversion history, do not start with exact at a high bid. Validate it through broad and phrase first, then promote.
• Ignoring match type in product targeting. Product targeting does not use match types, so sellers sometimes forget the entire concept when they switch to ASIN-level targeting. The relevance principle still applies, make sure your ASIN list is targeted, not just convenient.

Why Match Type Management Should Be Automated

Maintaining a clean match type structure manually is doable for sellers with one or two products. For anyone with more than that, the workload compounds fast.

Each new keyword that converts in broad needs to be promoted to phrase. Each phrase keyword that converts needs to be promoted to exact. Each non-converting term needs to be added as a negative in the right campaign. Bids across match types need to be rebalanced as conversion data shifts. None of this work makes you smarter. It just keeps your account from leaking money.

If you have been managing match types by hand for months, the time savings alone usually pay for the tool. The fact that the structure also tightens up and ACoS tends to drop is the bonus.

Frequently Asked Questions About Amazon PPC Match Types

What are the three match types in Amazon PPC?

Amazon Sponsored Products supports three keyword match types: broad match (loosest, shows on related searches and synonyms), phrase match (medium, shows on searches containing your keyword as a phrase), and exact match (tightest, shows only on near-identical searches). Each one trades reach for relevance differently.

Should I use broad match or exact match for Amazon PPC?

Use both, in different campaigns. Broad match is for keyword discovery, finding new search terms cheap. Exact match is for performance, bidding aggressively on keywords that have proven they convert. Phrase match sits between them as a middle tier. Running only one match type leaves money on the table.

Which Amazon match type has the highest conversion rate?

Exact match almost always has the highest conversion rate. Because it only shows on searches that match your keyword precisely, the shopper intent is unambiguous. Conversion rates on exact match are commonly 20% to 50% higher than the same keyword in broad match.

How much should I bid on each Amazon match type?

A common starting framework is exact match at 100% of your target bid, phrase match at 75% to 90%, and broad match at 50% to 70%. Calculate your target bid using the formula: average order value x conversion rate x target ACoS. Then adjust ratios based on each match type's actual conversion data.

What is the difference between phrase match and broad match on Amazon?

Phrase match requires your keyword to appear in the search query as a continuous phrase, in the order you specified. Broad match shows on related queries, synonyms, and loosely relevant searches without that ordering requirement. Phrase match gives more control. Broad match gives more reach.

Do I need negative keywords if I use exact match only?

You still benefit from negative keywords even with exact match, especially as negatives in your broad and auto campaigns to prevent them from competing with your exact match keywords. Without the negative loop, your discovery campaigns will keep bidding on terms you have already promoted to exact, creating internal competition and inflated CPCs.

Can I change match types after a keyword starts running?

You cannot change a keyword's match type directly. You have to pause or remove the existing keyword and add it again with the new match type. Do not delete the original, pausing keeps your historical data accessible for future reference.

Final Word on Amazon PPC Match Types

Match types are not a setting to fiddle with once and forget. They are the structural skeleton of a healthy Sponsored Products account. Get the structure right, and your campaigns get easier to manage and harder to break. Get it wrong, and you spend every weekend pulling reports trying to figure out why your ACoS keeps creeping up.

The principle to remember: each match type does one job well. Broad match finds new keywords. Phrase match validates them. Exact match exploits the winners at scale. The negative loop holds the whole thing together by stopping wasted spend before it happens.

Build the waterfall. Use the right bid ratios. Maintain the negative loop. Or let an automated system do it for you. Either way, your match type structure is one of the highest-leverage parts of your PPC account, and it deserves more than the “set everything to broad” approach most sellers default to.
