Google Ads has three keyword match types. Broad match shows your ad on searches related to your keyword, even ones that do not contain its direct meaning. Phrase match shows your ad on searches that include the meaning of your keyword. Exact match shows your ad on searches with the same meaning or intent as your keyword. Exact gives you the most control and the least reach. Broad gives you the most reach and the least control.
Those are Google’s own definitions, and the wording matters. Notice that all three are now described in terms of meaning, not in terms of the words themselves.
That change is the reason old advice about match types is dangerous. Exact match stopped meaning exact years ago. If you learned this in 2018, what you learned is no longer true.
How do you write each match type?
The syntax has not changed, even though the behavior has.
| Match type | How you type it | Example keyword | Could match |
|---|---|---|---|
| Broad | No punctuation | running shoes | trainers for jogging, best sneakers for a 5k, athletic footwear |
| Phrase | “Quotation marks” | “running shoes” | buy running shoes online, mens running shoes sale |
| Exact | [Square brackets] | [running shoes] | running shoes, shoes for running, running shoe |
What this means for you: even exact match will pick up rewordings and close variants. If you need a search term excluded, the only reliable tool is a negative keyword, not a tighter match type.
Which match type should you use?
Start with phrase and exact. Add broad only when you have reliable conversion tracking, a real negative keyword list, and enough conversion volume for Smart Bidding to steer it.
The reason is that broad match hands the targeting decision to Google’s model. That is fine when the model has good data about what a valuable conversion looks like. It is expensive when it does not, because Google will confidently spend your budget on searches that look related and are not.
The practical sequence we use:
- Launch with exact and phrase on the terms you are confident about.
- Run for thirty days and build the negative list from the search terms report.
- Once conversions are steady and the tracking is trustworthy, add broad in its own ad group so you can watch it separately.
- Keep pruning. Broad match is not a set and forget setting.
Is broad match actually bad?
No, but it is conditional. Broad match works when Google’s bidding model has accurate conversion data to learn from, and it fails badly when it does not.
Think of it this way. Broad match is Google asking, “may I decide who sees this ad?” The answer should depend on whether Google knows what a good outcome looks like in your business. If your conversion action fires on every form including the newsletter signup, Google does not know, and broad match will find you a lot of newsletter signups.
We have also seen the opposite. Accounts that cut broad match entirely and then wonder why volume is flat. If your exact match keyword list covers thirty terms in a market where people phrase things a hundred ways, you are invisible for seventy of them.
The honest position is that broad match is a volume tool that requires a working measurement layer as the price of entry. Get conversion tracking right first.
What happened to modified broad match?
It was retired. Modified broad match, the one written with plus signs, was folded into phrase match. If you still have plus signs in your account, those keywords are behaving as phrase match now.
This is worth checking, because a lot of accounts still carry keywords written in the old syntax and nobody has looked at them since the change. They are not broken, but they are not doing what whoever wrote them intended either.
How do negative keywords fit in?
Negative keywords are the only hard control you have. Match types shape where Google looks. Negatives are the only thing that says no.
Google covers them on the same keyword matching options page as an exclusion tool. Negatives have their own match types, and they behave differently from positive keywords in one important way: negative keywords do not match close variants. A negative for “free” will not block “freebie”. You have to be literal.
Three lists are worth building on almost every account:
- Generic waste. Free, cheap, jobs, careers, salary, DIY, template, course, reddit, youtube.
- Wrong intent. Terms that describe people researching rather than buying, if you only want buyers.
- Competitor and adjacent products you do not actually sell.
Our post on negative keywords in PPC goes deeper on building and maintaining these lists.
Should the same keyword exist in more than one match type?
Usually not, and this trips up a lot of accounts that were built years ago. The old practice was to add the same term as exact, phrase and broad, then set different bids for each. Smart Bidding made that pointless, because you no longer set the bids.
Google now generally prefers the most relevant keyword regardless of match type, so duplicating a term across match types mostly just makes your account harder to read.
The one case where it still helps is when you want to isolate broad match spend into its own ad group or campaign so you can watch it separately. That is a reporting decision, not a bidding one.
How do match types interact with bidding and budget?
Match types decide who sees the ad. Bidding decides how much you pay. Budget decides when you run out. The most common expensive combination is broad match plus a strategy that tries to spend the full budget plus a budget that is too small to cover the resulting traffic.
In that setup, Google finds hundreds of loosely related searches, spends your daily budget by lunchtime, and your best keywords never get a look in. If you are going to run broad on a small budget, run it in its own campaign with its own budget so it cannot cannibalize the rest.
Our posts on bidding strategies and setting a budget cover the other two sides of that triangle.
Common questions
Does exact match still mean exact?
No. Google matches exact keywords to searches with “the same meaning or same intent”, which includes reorderings, plurals, misspellings and synonyms. It is the tightest option available, but it is not literal.
Why is my ad showing for an unrelated search?
Either a broad or phrase keyword matched on meaning in a way you did not expect, or a close variant of an exact keyword matched. Find the term in the search terms report and add it as a negative. Then check whether the keyword that triggered it should stay.
Do match types affect cost per click?
Not directly. Cost per click is set by the auction and by Quality Score. What match types change is which auctions you enter, and loosely related auctions tend to have worse relevance, which does eventually feed into Quality Score and cost.
How many keywords should I have?
Fewer than you think. Large keyword lists made sense when match types were literal. Now that Google matches on meaning, thirty well chosen keywords will cover what three hundred used to, and they will gather conversion data far faster.
Does Performance Max use match types?
No. Performance Max does not use keywords at all, so match types do not apply. You can use negative keywords at the account level to exclude terms from it. Our Performance Max guide covers what control you do have.
Should ecommerce accounts use broad match?
Often yes, because product searches are phrased in endless ways and revenue tracking gives Google a strong signal to optimize against. The condition is that conversion value has to be tracked properly, not just conversion count. Our ecommerce PPC strategy post covers that setup.
Where to go from here
Open your search terms report for the last sixty days and sort by cost. If you do not recognize the top ten searches as things you sell, your match types are too loose for the negative list you currently have.
That is a thirty minute check anyone can do. If you would rather have us do it, our Google Ads management page explains how we handle keyword and negative work, and you can get in touch if you want a look at where your budget is actually going.
