💡 Summary Choosing the wrong keyword match type in Google Ads can drain your budget fast — showing your ads to completely the wrong people. In this guide, I’ll break down every Google Ads keyword match type, show you real examples of how they work, and tell you exactly when to use (and avoid) each one so your budget goes further.
If you’ve ever set up a Google Ads campaign and wondered why your ad showed up for searches that had nothing to do with your business — keyword match types are probably the reason.
Google Ads keyword match types control who sees your ads. Get them wrong, and you’re paying for clicks from people who will never buy from you. Get them right, and your ads reach exactly the people who are looking for what you offer.
In this guide, we’ll cover all three match types — Broad Match, Phrase Match, and Exact Match — plus how to use Negative Keywords to block wasted spend. By the end, you’ll know exactly which match type to use for each campaign.
Let’s get into it. 👇
What Are Keyword Match Types in Google Ads?
When you add a keyword to a Google Ads campaign, you’re not just telling Google what to target — you’re also telling it how loosely or tightly to interpret that keyword.
That’s what match types control.
Google offers three keyword match types:
- Broad Match — the widest reach, most flexible
- Phrase Match — middle ground between reach and control
- Exact Match — the tightest targeting, most controlled
Each one tells Google how closely a user’s search query needs to match your keyword before your ad is eligible to show.
Think of it like a filter. Broad Match is a loose filter — lots of searches pass through. Exact Match is a tight filter — only very specific searches get through. Phrase Match sits in the middle.
Getting this right is one of the most important things you can do when setting up a Google Ads campaign. Let’s look at each one.
Broad Match — Maximum Reach, Less Control
What Is Broad Match?
Broad Match is Google’s default match type. When you use a Broad Match keyword, Google can show your ad for searches that are related to your keyword — even if the search doesn’t contain your exact keyword at all.
Google uses signals like the user’s search history, the content of your landing page, and other keywords in your ad group to decide when your ad is relevant.
Example:
- Your keyword:
running shoes - Your ad could show for: “best trainers for jogging”, “sneakers for marathon training”, “comfortable footwear for runners”
As you can see, Google is making interpretive decisions about what’s “related” to your keyword.
When to Use Broad Match
Broad Match works best when:
- You have Smart Bidding enabled (Target CPA or Target ROAS). Google’s algorithm uses conversion data to filter out irrelevant traffic automatically.
- You’re running a brand awareness campaign and want maximum exposure.
- You’re in the early stages of a campaign and want to discover what search terms people actually use before narrowing down.
- You have a healthy negative keyword list already built out to block irrelevant searches.
When NOT to Use Broad Match
Avoid Broad Match if:
- You have a small budget. Broad Match burns through spend quickly on unrelated searches.
- You’re new to Google Ads and don’t yet have conversion data. Without Smart Bidding working in your favour, Broad Match is largely ungoverned.
- Your product or service is niche or easily confused with something else.
How to Add a Broad Match Keyword
Simply type your keyword without any special formatting:
running shoesNo brackets, no quotes. That’s it.
Phrase Match — The Sweet Spot for Most Campaigns
What Is Phrase Match?
Phrase Match sits between Broad and Exact. Your ad will show when someone searches for your keyword’s meaning, including searches that contain additional words before or after it.
Since 2021, Phrase Match has replaced the old Modified Broad Match type and now covers a wider range of relevant variations.
Example:
- Your keyword:
"running shoes" - Your ad could show for: “buy running shoes online”, “best running shoes for women”, “cheap running shoes near me”
- Your ad would NOT show for: “shoes for hiking” or “basketball trainers” (different intent)
The key difference from Broad Match is that Phrase Match respects the core meaning of your keyword. It won’t wildly stray into unrelated territory.
When to Use Phrase Match
Phrase Match is the go-to choice for most campaigns because it balances reach and relevance. Use it when:
- You want to reach a range of searchers without completely losing control of who sees your ad.
- You’re targeting product or service keywords where people use slightly different wording.
- You want to capture long-tail variations of your core keyword without setting up hundreds of individual exact match keywords.
- You’re running lead generation campaigns where reaching a broader (but still relevant) audience matters.
When NOT to Use Phrase Match
- When your keyword could mean different things to different audiences (use Exact Match instead to maintain precision).
- When budget is extremely limited and you need maximum control over every click.
How to Add a Phrase Match Keyword
Wrap your keyword in quotation marks:
"running shoes"Exact Match — Maximum Control, Limited Reach
What Is Exact Match?
Exact Match is the most restrictive match type. Your ad will only show when someone searches for your exact keyword, or very close variants like misspellings, singular/plural forms, abbreviations, and reordered words with the same meaning.
Example:
- Your keyword:
[running shoes] - Your ad could show for: “running shoes”, “running shoe”, “shoes for running”
- Your ad would NOT show for: “buy running shoes online” or “best running shoes for men” (additional words = excluded)
When to Use Exact Match
Exact Match is ideal when:
- You know exactly what your customers search for and you want to target only that query.
- You’re running a high-intent campaign where you’re willing to sacrifice volume for precision (e.g. targeting “emergency plumber London” rather than anything plumbing-related).
- You’re remarketing or promoting a specific offer and don’t want unrelated traffic diluting your results.
- You want to control spend tightly — every click is intentional.
When NOT to Use Exact Match
- When you’re starting out and aren’t yet sure exactly how people search for your product.
- When you want to scale reach — Exact Match limits how many people see your ads.
- As your only match type — most campaigns benefit from a combination of match types.
How to Add an Exact Match Keyword
Wrap your keyword in square brackets:
[running shoes]Negative Keywords — Your Secret Weapon 🛡️
No guide to Google Ads keyword match types is complete without talking about Negative Keywords.
Negative Keywords tell Google when not to show your ad. They’re the filter that prevents your budget from being wasted on irrelevant searches.
Example:
- You sell premium running shoes (£100+)
- You add
-free,-cheap,-DIYas negative keywords - Now your ad won’t show to people looking for free or cheap options who’d never convert anyway
Types of Negative Keywords
Negative keywords also have match types:
- Negative Broad Match (default): Blocks searches containing all the words in your negative keyword in any order.
- Negative Phrase Match (
"free running shoes"): Blocks searches that contain your negative keyword phrase in that order. - Negative Exact Match (
[free running shoes]): Blocks only that exact search query.
How to Build Your Negative Keyword List
- Run your campaign for 1–2 weeks
- Go to Keywords → Search Terms in your Google Ads account
- Look for searches that triggered your ad but have zero buying intent
- Add those terms as negative keywords
- Repeat monthly
Building a strong negative keyword list is one of the fastest ways to improve your campaign’s ROI — especially if you’re using Broad or Phrase Match.

Which Match Type Should You Use? The Practical Answer
Here’s the truth: you don’t have to choose just one.
Most well-structured Google Ads campaigns use a combination of match types. Here’s a simple framework to start with:
For beginners with a limited budget: Start with Phrase Match and Exact Match only. This gives you good reach without the unpredictability of Broad Match. Build your negative keyword list as you go.
For campaigns with Smart Bidding enabled: Broad Match becomes much more powerful because Google’s algorithm uses your conversion data to filter for relevant traffic. Many experienced advertisers run primarily Broad Match + Smart Bidding + a strong negative keyword list.
For high-intent or high-ticket campaigns: Lean on Exact Match for your most valuable keywords, and use Phrase Match to capture variations. Reserve Broad Match for a separate discovery campaign with a smaller budget.
A simple starting structure:
- Add your core keywords as Exact Match
- Add supporting variations as Phrase Match
- (Optional) Add 1–2 Broad Match keywords if using Smart Bidding, with a budget cap
- Build your negative keyword list from week one
Common Keyword Match Type Mistakes to Avoid ❌
1. Using only Broad Match as a beginner Without Smart Bidding and a solid negative keyword list, Broad Match will show your ads to irrelevant searches and drain your budget.
2. Never checking the Search Terms report Your Search Terms report shows you the actual searches triggering your ads. Check it weekly. You’ll find negative keywords to add and new keyword ideas you hadn’t thought of.
3. Putting all match types in the same ad group If you have the same keyword in Broad, Phrase, and Exact Match in the same ad group, Google will struggle to decide which to prioritise. Keep them in separate ad groups or campaigns.
4. Ignoring Negative Keywords entirely This is one of the most expensive mistakes in Google Ads. Even Phrase and Exact Match can trigger irrelevant searches — negative keywords are always worth building.
5. Never updating your match types As your campaign matures and you collect conversion data, it’s worth testing moving from Exact/Phrase to Broad Match with Smart Bidding. Many campaigns see volume increase significantly without sacrificing efficiency.
Final Thoughts
Getting your Google Ads keyword match types right is one of the highest-leverage things you can do in your account. The difference between Broad, Phrase, and Exact Match isn’t just technical — it’s the difference between paying for clicks that convert and paying for clicks that disappear.
To recap:
- Broad Match = maximum reach, use with Smart Bidding and a strong negative list
- Phrase Match = best all-rounder for most campaigns
- Exact Match = maximum control, best for high-intent and high-ticket campaigns
- Negative Keywords = non-negotiable, regardless of which match types you use
Start with Phrase Match and Exact Match, build your negative keyword list from week one, and test Broad Match once you have conversion data coming in.
