Keyword match types are one of the first settings you touch in Google Ads, and one of the most misunderstood. Many business owners still think exact match means "only this exact phrase" and broad match means "anything vaguely related". Both ideas are out of date. Google has changed how every match type works several times, and the way they behave today depends a lot on your bidding strategy and conversion tracking.
This guide explains what broad, phrase and exact match actually do now, how close variants affect each one, why negative keywords follow different rules, and how I choose match types for small business accounts.
What are keyword match types in Google Ads?
Keyword match types tell Google how closely a person's search must relate to your keyword before your ad can show. There are three: broad match, phrase match and exact match. Each one trades reach for control.
| Match type | How you write it | What it can match | Control |
|---|---|---|---|
| Broad match | house cleaning service |
Searches related to the meaning of the keyword, including related topics | Lowest |
| Phrase match | "house cleaning service" |
Searches that include the meaning of the keyword, with words before or after | Medium |
| Exact match | [house cleaning service] |
Searches with the same meaning or intent as the keyword | Highest |
The important word in every row is "meaning". Google no longer matches only on the literal words you enter. It matches on what it thinks the search means.
What are close variants?
Close variants are searches that Google treats as equivalent to your keyword even though the words differ. They apply to all three match types, including exact match.
Close variants can include:
- Misspellings, such as "hosue cleaning"
- Singular and plural forms
- Stemming, such as "clean" and "cleaning"
- Abbreviations and acronyms
- Reordered words when the meaning stays the same
- Added or removed function words like "in", "for" or "the"
- Implied words or paraphrases with the same intent
So [chimney sweep near me] could match "chimney sweeper near me" or "chimney sweeping nearby". You cannot turn close variants off. The only way to see what you are really matching is the search terms report, which I cover below.
How does broad match work?
Broad match shows your ad on searches related to your keyword, using signals beyond the words themselves. Google says broad match can consider things like the other keywords in your ad group, your landing pages and the user's recent searches to decide whether a search is relevant.
That makes broad match the widest-reaching option. A broad keyword like carpet cleaning could show for "rug cleaning service", "stain removal company" or "steam cleaner hire", and some of those are not what you want.
Why does broad match work best with Smart Bidding?
Broad match works best with Smart Bidding because Smart Bidding sets a bid for each individual auction based on how likely that search is to convert. When broad match brings in a weak search, a well-trained bidding strategy can bid low or not at all. When it finds a valuable search you never thought of, it can bid higher.
Without Smart Bidding, broad match spends the same manual bid on good and bad searches alike. That is why I do not combine broad match with manual CPC in small accounts.
Even with Smart Bidding, broad match only works if:
- Conversion tracking records real leads or sales, not button clicks.
- The account has enough conversion volume for the algorithm to learn.
- You review search terms regularly and add negatives.
- Your budget can absorb some exploratory traffic.
If you are not sure which bidding strategy fits your account, my post on Smart Bidding: Max Conversions vs Target CPA vs Target ROAS explains the options.
Google has also been adding features that extend matching beyond keywords, such as AI Max for Search campaigns, which can match searches using your landing pages and assets. These build on broad match logic, so the same rule applies: strong conversion data first, automation second.
How does phrase match work?
Phrase match shows your ad on searches that include the meaning of your keyword. Extra words can appear before or after, and Google may allow some reordering if the meaning stays the same.
For example, "move out cleaning" could match:
- "move out cleaning cost"
- "best move out cleaning company in Dallas"
- "end of tenancy move out cleaning"
It should not match "move out checklist" because the meaning is different. Phrase match also absorbed the old broad match modifier, which Google retired a few years ago.
For most local service businesses, phrase match is my default starting point. It captures the long, specific searches real customers type, while staying close enough to the service that you keep control.
How does exact match work?
Exact match shows your ad on searches that have the same meaning or intent as your keyword. It is the tightest option, but because of close variants it is not literally exact.
[emergency plumber] could match "plumber emergency" or "emergency plumbers", and in some cases a paraphrase with the same intent. It should not match "emergency plumber salary".
When a search is identical to one of your exact match keywords, Google says it will generally prefer that keyword over other eligible keywords in the account. That is useful when you want a specific ad and landing page to show for your most valuable searches.
I use exact match for:
- Core, high-value service keywords where I want the most control
- Brand keywords
- Keywords that have proven themselves in the search terms report
How do negative keyword match types differ?
Negative keyword match types work differently from positive ones because they do not expand to close variants. A negative keyword blocks only what you literally enter, in the way its match type describes.
| Negative type | Example | What it blocks |
|---|---|---|
| Negative broad | jobs cleaning |
Searches containing both words, in any order |
| Negative phrase | "cleaning jobs" |
Searches containing that exact phrase, in that order |
| Negative exact | [cleaning jobs] |
Only that exact search, with no extra words |
Because close variants are not included, you often need to add plurals and misspellings separately. Negative job does not block "jobs". For a full list of what to block, see my guide to negative keywords for local service businesses.
How do you check what your keywords are really matching?
You check by opening the search terms report, which shows the actual searches that triggered your ads and which keyword matched each one. Google hides some low-volume searches for privacy, so you will not see everything, but you will see enough to spot patterns.
My weekly routine for a new account:
- Filter search terms by the last seven days.
- Sort by cost.
- Add irrelevant terms as negatives at the right level (ad group, campaign or a shared list).
- Add strong converting terms as their own phrase or exact keywords if they deserve dedicated ads.
- Note which keywords trigger the most off-topic terms and consider tightening them.
Which match types should a small business use?
A small business with limited budget and data should usually start with phrase and exact match, then test broad match once Smart Bidding has reliable conversion data. That order keeps early spend focused.
A practical progression:
- Launch: Phrase and exact match on core services, a solid negative list and accurate conversion tracking.
- After conversion data builds: Move to a Smart Bidding strategy and keep reviewing search terms.
- Testing broad: Add broad match to a proven ad group, or test it in a separate campaign, and compare cost per conversion against your phrase and exact keywords.
Keep ad groups tightly themed whichever match type you use. Match types work much better inside a clean Google Ads account structure.
Final thoughts
Match types are not a set-and-forget choice. They interact with bidding, tracking and negatives, and the right mix changes as your account matures. If you want help building a keyword strategy around your services, see how I manage Google Ads for local service businesses, or book a free audit.
