Broad match Google Ads keywords promise more reach with less keyword work, and broad is now the default match type. I have managed paid search since 2013, and in my accounts broad only pays off once Smart Bidding has conversion data to learn from. Below I explain why I start new Search campaigns on exact match, when I open up, and why Performance Max usually does the broad job.
Quick Answer: Should you use broad match in Google Ads?
Use broad match only when the account already has steady conversion data, verified tracking and Smart Bidding. On new campaigns I start Search on exact match for roughly the first 15 days, build negatives up front, and let Performance Max handle broad reach once conversions exist. Exact costs more per click, but the traffic matches.
Key Observations
- Broad is the default match type, and Google says it is critical to pair it with Smart Bidding.
- Smart Bidding learns from conversions, so broad match has little to work with in a new account.
- I run new Search campaigns on exact match for roughly the first 15 days.
- Negatives go in up front, in phrase and exact match, at account level.
- Exact match Search keywords take priority over Performance Max when a query hits them.
- Campaigns on the campaign-level broad match setting move to AI Max from September 2026.
Here is how the three keyword match types compare, using Google’s own syntax and examples.
| Match type | Syntax | What it can match | When I use it |
|---|---|---|---|
| Broad | low carb diet plan | Related searches, even ones without the keyword’s direct meaning, such as mediterranean diet books | Only after conversion data and Smart Bidding are in place |
| Phrase | “tennis shoes” | Searches that include the meaning of the keyword, often in a more specific form | Negative lists, and keywords where exact is too narrow |
| Exact | [red shoe] | Searches with the same meaning or intent as the keyword | The first weeks of every new Search campaign, and proven terms after that |

How does broad match work in Google Ads?
Broad match lets your ad show on searches related to your keyword, even when the search does not contain its direct meaning. Google’s own example is the keyword low carb diet plan showing for searches like mediterranean diet books. It is the default match type, so any keyword typed without symbols is broad.
To decide what counts as related, Google looks at more than the keyword. Its help page says broad match can consider the user’s recent search activity, your landing page and assets, and the other keywords in the ad group. That is why a broad keyword in a loose ad group can wander far from what you sell.
How is broad match different from phrase and exact match?
Phrase match shows your ad on searches that include the meaning of your keyword. Exact match shows it on searches with the same meaning or intent. Google describes exact match as giving you the most control over who sees your ad, with the least reach. Broad sits at the other end, with the most reach and the least control.
Google also treats very similar keywords, such as red car and car red, as duplicates and uses only one bid in the auction. So adding word-order variations does not buy you extra reach.
Why do I start new Search campaigns on exact match?
I start on exact match because a new account has no conversion data, and broad match depends on it. Google says it is critical to use Smart Bidding with broad match. Smart Bidding, in turn, needs conversion tracking enabled before you can use it at all.
Even with tracking live, Smart Bidding learns from conversions. Google recommends judging its performance over periods with at least 30 conversions, or 50 for Target ROAS. A brand new campaign has none, so broad match would be guessing with your budget.
So for roughly the first 15 days, new Search campaigns run on exact match. Exact terms cost more per click, but the traffic matches what the business sells. Those days build the conversion data and audience history that later campaigns rely on.
Is exact match too expensive for a small account?
It can be, and I handle that with bidding rather than looser match types. On low-volume, exact-only accounts, exact match CPCs run high, so I test manual CPC to control the cost per click. I cover that test in my manual CPC guide.
Accounts with enough conversion data go on Maximize conversion value instead. Once ROAS has been stable for about 30 days with no target, I switch to target ROAS, one of Google’s Smart Bidding strategies. Then I push the target up by 15% to 20%, always judged against break-even ROAS.
When does broad match actually work?
Broad match works when the account can teach it what a good click looks like. In practice, four things need to be true before I let broad run:
- Conversion tracking is verified in GA4, Google Tag Manager and Google Ads, with enhanced conversions where it applies.
- The account has steady conversion data, not a handful of sales.
- The campaign runs on Smart Bidding, which Google treats as essential for broad match.
- A negative keyword list is already in place, in phrase and exact match, at account level.
If any of those is missing, broad match tends to find cheap, loosely related searches and spend on them. I have seen that pattern in accounts my team took over, and in the two below the fix started with search terms and negatives.
Can you use broad match with manual CPC?
You can, but Google does not recommend it, and neither do I. Google says it is critical to use Smart Bidding with broad match. Its campaign-level broad match setting was only available with conversion-based Smart Bidding. On manual CPC, broad match reaches widely without the auction-time signals that keep it in check.
Why do I let Performance Max do the broad job?
Once there is conversion data, I would rather let Performance Max find new demand than open Search to broad match. Performance Max can reach all Google Ads inventory, including YouTube, Display, Search, Discover, Gmail and Maps, from a single campaign. That makes it the broadest tool in the account.
The two work together because of how Google prioritizes them. Google says Search campaigns with an exact match keyword are prioritized over Performance Max when a query hits that keyword. Search themes carry the same priority as phrase and broad match keywords. So exact match Search keeps the searches I already know convert, and Performance Max explores the rest.
Before Performance Max goes live, I set guardrails. Account-level negatives go in, in phrase and exact match, and Google confirms they apply to Search and Shopping inventory in Performance Max. I also exclude irrelevant placements, and exclude blog and other non-selling URLs so the campaign only sends traffic to converting pages. The full launch process is in my Performance Max campaign guide.
How do negative keywords protect you when you open up match types?
Negatives are the brake, and they need to be in place before you press the accelerator. Negative keywords do not match close variants, so you have to add synonyms and singular or plural forms yourself. In Google’s negative keyword example, a negative for flowers blocks red flowers but not red flower.
I build the list up front in phrase and exact match rather than waiting for waste to show up. Negative phrase blocks the terms in that order, even with extra words around them. Negative exact blocks only that exact search, which helps when a term is bad on its own but fine inside a longer query.
I also prefer account-level negatives over campaign-level lists alone. Google lets each account hold up to 1,000 negative keywords that apply across Search, Shopping, Performance Max, App, Smart and Local campaigns. If a negative is missed at campaign level, the account list still catches it.
Context still matters. In the CANA Wine Company account, negatives sit at account level, and the CANA case study warns against blanket-negating the word gift, because gifting is a strong buying theme for that store. I review search terms on a schedule, as I explain in my search terms report guide.
What happened in accounts where loose matching was the problem?
Two accounts show what loose traffic costs, and both fixes started with search terms and negatives. In a local signage company’s account, ROAS sat at 1.5x when my team took over. The signage case study notes it was likely losing budget to broad, low-intent traffic.
Local signage searches pull in DIY sign makers, job seekers and people looking for software tools. We audited search terms, built negatives, rebuilt campaigns and match types around the services that convert, and checked that tracking counted real leads and sales. The case study reports ROAS moving from 1.5x to 7.35x for May and June 2026, per the results table.
A commercial cleaning equipment supplier had the same problem from another angle. Homeowners seeking domestic cleaners, job seekers and DIY repair searches were using budget meant for facility managers. We built a negative keyword system to block those queries, split campaigns by intent and limited targeting to the service area.
Comparing two 90-day periods, conversions rose from 29 to 154 and cost per conversion fell 73%, per the cleaning equipment case study. Bidding moved to conversion-focused strategies only once there was enough data. That is the same order I follow before any broad match test.
Local service accounts are where loose matching hurts most, because so many searches look relevant but are not. CMSC, a driving school, is one local client that has shared its experience on video.
If your search terms report is full of searches you would never pay for, I can show you where the waste sits and how to close it.
What changed with broad match and AI Max in 2026?
The campaign-level broad match setting made a whole Search campaign use broad match, and it needed conversion-based Smart Bidding. Google’s help page says campaigns using that setting are automatically upgraded to AI Max for Search starting in September 2026. If you used the setting, your campaigns have likely moved already.
AI Max goes further than broad match. Google describes it as combining broad match, asset-based targeting and keywordless technology, plus text customization and final URL expansion. If a campaign was upgraded, check which landing pages it now sends traffic to, and exclude pages that do not sell.
One detail is easy to miss. When broad keywords leave the campaign-level setting, Google stops treating them as exact match for prioritization, and it suggests adding exact match copies to keep the old behavior. That is one more reason to keep proven terms on exact match.
How do I open an account up from exact to broad?
I open up in stages, and each stage needs evidence before the next one starts. This is the order I follow on a new account:
- Run new Search campaigns on exact match for roughly the first 15 days, with account-level negatives in phrase and exact already in place.
- Verify conversion tracking in GA4, Google Tag Manager and Google Ads before touching bids or structure.
- Review the search terms report and add waste to the account-level list.
- Once conversion data builds up, launch Performance Max with guardrails so it does the broad job.
- Move bidding to Maximize conversion value, then to target ROAS after about 30 stable days.
- Test broad match in Search only if exact match and Performance Max leave clear demand unreached.
Step six is optional. When Performance Max has guardrails and data, it covers the reach broad match would add, and the Search campaign stays clean. I judge every stage against break-even ROAS, which is one divided by the profit margin.
FAQs
Is broad match good for new Google Ads campaigns?
Usually not in Search. A new campaign has no conversion data, and Google says broad match should run with Smart Bidding, which learns from conversions. I start new Search campaigns on exact match for roughly the first 15 days, then let Performance Max take on broad reach once the account has conversions to learn from.
What is the difference between exact match and broad match?
Exact match shows your ad on searches with the same meaning or intent as your keyword. Broad match can show it on any related search, even one without your keyword’s direct meaning. Exact gives you the most control and usually costs more per click. Broad gives the most reach and needs Smart Bidding plus strong negatives.
Does broad match work with manual CPC?
It runs, but Google says it is critical to use Smart Bidding with broad match, and the campaign-level broad match setting needed conversion-based Smart Bidding. Without auction-time signals, broad match reaches widely with nothing steering it toward buyers. On manual CPC, I keep keywords on exact match and control the cost per click directly.
Do negative keywords block close variants of a search?
No. Google says negative keywords do not match close variants, so a negative for flowers will not block red flower. You need to add synonyms, plurals and misspellings yourself. That is why I build negative lists in phrase and exact match up front, and keep the main list at account level.
Does an exact match keyword beat Performance Max for the same search?
Generally, yes. Google says Search campaigns with an exact match keyword are prioritized over Performance Max when a query hits that keyword. Search themes in Performance Max carry the same priority as phrase and broad match keywords. That is why I keep proven, high-intent terms on exact match in Search.
What happened to the broad match campaign setting?
Google’s help page says Search campaigns using the campaign-level broad match setting are automatically upgraded to AI Max for Search starting in September 2026. AI Max combines broad match with keywordless matching, text customization and final URL expansion. If your campaigns were upgraded, check their landing pages and search terms closely.
How much conversion data do you need before using broad match?
Google does not give one number for broad match. For Smart Bidding, it recommends judging performance over periods with at least 30 conversions, or 50 for Target ROAS. I wait for steady conversion data and stable results, then let Performance Max take the broad role before I consider broad match in Search.
What should you do next with your match types?
Open your search terms report and look at what your broad and phrase keywords actually matched. If most of the spend sits on searches you would never choose, move back to exact match, build account-level negatives, and fix tracking before you open up again.
