What Are Keyword Match Types? Broad, Phrase and Exact Explained

Here’s a made-up story about two furniture sellers in Bengaluru, Meera and Arjun, who both sold ergonomic office chairs online and both started Google Ads in the same week. Meera added one keyword, office chair, on broad match and set a daily budget. Arjun added a dozen tightly written keywords like “ergonomic office chair” and [office chair with lumbar support], plus a list of words he didn’t want to pay for. By lunchtime on day one, Meera’s budget was gone. Her ads had shown for office chair repair, second-hand office chairs, gaming chairs and office chair wheels.

Arjun’s campaign spent slowly and sold chairs. But a month later he noticed something Meera’s messy campaign had stumbled onto: people searching for things like “chair for back pain while working from home” were buying, and none of his keywords reached them. Neither of them was simply right. They had each set a dial that decides how far Google can stretch a keyword, and that dial is called the match type.

What keyword match types actually mean

In plain terms, a match type tells Google how loosely or tightly it can interpret your keyword when deciding whether to show your ad.

The formal version: match types are keyword settings in Google Ads and Microsoft Advertising that control which search queries are eligible to trigger an ad. There are three: broad match, phrase match and exact match. You choose a match type for every keyword you add, and you can use different ones side by side in the same account.

The key nuance is the difference between a keyword and a search term. The keyword is what you add to your account. The search term is what a real person typed. Match types govern the gap between the two, and in modern search ads that gap is never zero. Even exact match now covers close variants: plurals, misspellings, abbreviations, reordered words and searches with the same meaning. Match types used to be about matching words. Today they’re about matching meaning, with different amounts of freedom.

How each match type works

Broad match is written with no symbols, like office chair. Your ad can show on searches related to your keyword, even when the search doesn’t contain any of its words. Google uses signals such as the other keywords in your ad group, your landing page and the person’s recent searches to decide what’s related. Office chair on broad match might reach “ergonomic seating for home office” or “desk chair for tall people”, along with less useful searches.

Phrase match is written in quotation marks, like “office chair”. Your ad can show on searches that include the meaning of your keyword. Extra words can come before or after, and word order matters where changing it would change the meaning. “Office chair” might reach “buy office chair online” or “best office chair for back pain”, but not “chair for an office party”.

Exact match is written in square brackets, like [office chair]. Your ad can show on searches with the same meaning or the same intent as your keyword, such as office chairs or chair for office. It won’t show for office chair repair, because that’s a different intent.

Match types also interact with bidding. Broad match relies heavily on your conversion data, which is why Google recommends pairing it with Smart Bidding strategies that optimise for conversions or conversion value. With manual bidding and no conversion data, broad match has little to learn from, and it tends to spend on anything loosely related.

Negative keywords: the other half of the system

Match types decide where your ads can go. Negative keywords decide where they can’t. They’re the brakes to match types’ accelerator.

Negatives come in the same three types. A negative broad keyword blocks searches that contain all of its words in any order. A negative phrase keyword blocks searches containing that exact phrase. A negative exact keyword blocks only that exact search.

The detail that catches people out is that negatives don’t expand to close variants. Adding repair as a negative won’t block repairs or repairing. If you want to exclude a word, add its plurals and common misspellings as well. Most accounts benefit from a shared negative list covering the searches you never want: jobs, free, used, second hand, DIY, repair, and competitor names if you’ve decided not to bid on them.

A worked example: one budget, two setups

This is a hypothetical example with example numbers, continuing Meera and Arjun’s story over their first full week.

Meera spent ₹21,000 on her single broad match keyword with manual bids and no negatives. She got 2,800 clicks and 9 orders, a cost of about ₹2,333 per order. Her search terms report showed hundreds of clicks on repair, second-hand and spare-part searches that could never convert.

Arjun’s phrase and exact keywords, backed by his negative list, couldn’t spend his full budget because fewer searches matched. He spent ₹12,600, got 1,050 clicks and 14 orders, about ₹900 per order.

Arjun then ran a controlled test. He set up a separate broad match campaign on a few of his best keywords, with his full negative list attached, conversion tracking checked, and a target CPA bid strategy. Over the next month it spent carefully, found searches like “chair for back pain while working from home”, and delivered orders at about ₹1,100 each. That’s higher than his exact keywords, but far lower than Meera’s, and it reached buyers his tight keywords had been missing. He added the best of those discovered searches to his main campaign as new exact match keywords.

Meera, meanwhile, added forty negatives from her search terms report and switched her bidding to Smart Bidding once she had enough conversions. Her cost per order started falling within weeks. The lesson for both was the same: match type is a control dial, and where you set it depends on the data, bidding and negatives behind it.

Broad vs phrase vs exact match

	Broad match	Phrase match	Exact match
How it’s written	office chair	”office chair”	[office chair]
Can match	Searches related to your keyword	Searches that include your keyword’s meaning	Searches with the same meaning or intent
Reach	Widest	Middle	Narrowest
Control	Least	Moderate	Most
Works best with	Smart Bidding, solid conversion data, strong negatives	Most accounts as a starting point	Proven, high-value searches
Main risk	Spending on loosely related searches	Missing searches worded differently	Too little volume to learn from

There’s no single best match type. Exact match gives you control over your most valuable searches. Phrase match balances reach and relevance and is a sensible default for new accounts. Broad match is the discovery tool, most useful once your tracking and bidding can tell good traffic from bad. Most healthy accounts use at least two of the three, each doing a different job.

How to choose and set up match types

1. Check your conversion tracking first. Every match type decision depends on knowing which searches lead to sales or leads. Broad match in particular needs accurate conversions to learn from.
2. Start with phrase and exact for your core terms. Build keywords around the searches you’re confident will convert. This gives you clean data and controlled spend in the first weeks.
3. Build a negative list before you launch. Write down searches you never want to pay for, and add plurals and variants, since negatives don’t cover close variants.
4. Read the search terms report every week. It shows what people actually typed. Add irrelevant searches as negatives and valuable ones as new keywords.
5. Promote proven searches to exact match. When a search term converts well, add it as an exact keyword so you can bid on it and write ads for it directly.
6. Test broad match deliberately. Once you have steady conversions, try broad match with Smart Bidding in a separate campaign or a campaign experiment, and compare cost per conversion against your existing setup.
7. Keep the structure simple. Avoid dozens of near-identical keywords split across ad groups. Fewer, well-chosen keywords give bidding more data to work with.

Common match type mistakes

Running broad match with manual bids and no negatives. This is Meera’s day one. Without conversion-based bidding or negatives, broad match has nothing stopping it from spending on loosely related searches.

Assuming exact match means exact. Close variants mean your exact keywords can show for plurals, reorderings and same-meaning searches. That’s usually fine, but check the search terms report rather than assuming.

Forgetting that negatives don’t cover variants. One negative for a word won’t block its plural or misspelling. Add the versions that matter, or relevant waste keeps slipping through.

Never reading the search terms report. It’s the only place you see what you’re actually paying for. Accounts that skip it tend to fund irrelevant searches for months.

Splitting keywords too finely. Old habits like one keyword per ad group across every match type create sprawling accounts where no keyword gets enough data. Modern bidding works better with simpler structures.

How to tell if your match types are working

There’s no benchmark share of broad or exact keywords you should aim for. Watch these signals instead:

• Most spend in your search terms report goes to searches you’d happily pay for.
• New irrelevant searches are rare and get added as negatives quickly.
• Cost per conversion from broad match campaigns sits within a range you can afford.
• Your exact match keywords cover your most valuable, proven searches.
• Each keyword gets enough traffic to produce useful data within a few weeks.

Key takeaways

• Match types decide how far Google can stretch a keyword: broad the most, phrase in the middle, exact the least.
• All three now match meaning, not just words, so read your search terms report to see what they really trigger.
• Negative keywords are the other half of the system, and they don’t expand to close variants.
• Broad match works best with reliable conversion tracking, Smart Bidding and strong negatives.
• Start controlled with phrase and exact, promote winners, and test broad match deliberately.
