Google Ads Match Types: Negatives and Search Terms
What broad, phrase and exact match change, how a negative list is built, and when to read search terms: a clear framework for the decision-maker.

Short answer
Google Ads has three match types: broad, phrase and exact; the one you pick decides which searches your ad appears on and how much of your budget lands on clicks that were never going to convert. Broad match reaches the widest volume with the loosest control; exact match reaches the narrowest volume with the tightest control. The gap between the two is closed by a negative keyword list.
Most business owners set a match type once when a campaign is built and never revisit it. Left unchecked, broad match keeps quietly feeding budget into unrelated searches unless the search terms report gets opened every week; it is one of the most common ways Google Ads budget leaks away.
This piece covers what the three match types actually do, how a negative keyword list gets built, and when and how to read the search terms report.
What separates broad, phrase and exact match
Broad match shows an ad on any search Google judges as related to the keyword entered, including synonyms, related searches, and sometimes loosely connected phrasing. It reaches the widest audience, and carries the highest risk of an unrelated click.
Phrase match, entered in quotation marks, shows an ad when a search contains the exact phrase in the same order, with other words allowed before or after it. Exact match, entered in brackets, fires when a search matches the keyword's meaning closely or exactly; it is the narrowest option and the closest to genuine intent.
Take a flooring manufacturer as an example. Broad match on 'floor covering' might show an ad on a distant search like 'cheap laminate flooring where to buy', while exact match only fires on 'floor covering prices' and very close variations of it.
Which match type fits which stage of a campaign
In a new campaign, broad match is useful for discovering which searches actually drive conversions, but that discovery only pays off if the search terms report gets checked regularly. Left unwatched, broad match drifts towards unrelated searches over time.
As a campaign matures, phrases from the search terms report that drive conversions get moved to exact or phrase match; these are now 'proven' phrases and run with less waste and a tighter fit. That move usually happens after a few weeks of data, not on day one.
A typical path for a spa chain's booking campaign: start on broad match, and after two or three weeks the search terms report surfaces intent-clear phrases like 'how to book a massage appointment'; those move to exact match, and the remaining broad match group is tightened.
Why the negative keyword list matters as much as match type
A negative keyword is a rule that stops an ad showing for a specific search altogether. No matter how tight the match type, some unrelated searches still slip through without a negative list; broad match makes that leak wider.
If a workwear manufacturer bids on 'work clothing', searches like 'how to sew work clothing' or 'second-hand work clothing' will bring clicks that never convert; adding those to the negative list blocks them.
A negative list is not a one-off setup; it grows through the life of a campaign. Every new unrelated search that shows up gets added; without reading the search terms report, the negative list stays incomplete too.
- Spot searches that aren't working from the search terms report
- Add those searches as negatives at campaign or account level
- Pre-block generic words that never fit the business (e.g. 'free', 'job vacancy')
- Review the list once a month and remove negatives that are no longer needed
How to read the search terms report, step by step
The search terms report opens from the 'Search terms' tab at campaign or ad group level in a Google Ads account; it lists the actual search queries an ad showed for, alongside clicks and conversions each one brought.
Once it's open, sort by the conversions column first; a search that drove conversions but isn't already added as a keyword can be added directly as a new keyword. In the other direction, searches that pulled clicks with no conversions and look unrelated to the business get moved to the negative list.
For a membership campaign run by an association, this report gets opened once a week for fifteen or twenty minutes; that small routine check is what keeps a meaningful share of monthly budget from going to unrelated clicks.
The common mistake: set match type once and never look again
The most frequent mistake is building a campaign on broad match and never opening the search terms report. The system looks like it's 'learning', but budget is quietly drifting to the wrong searches; the loss noticed months later can't be recovered.
The second common mistake runs the other way: pulling every keyword to exact match and shutting off new-search discovery entirely. That raises click quality in the short term but narrows reach over time and misses new customer phrases. The right balance is a mix of both, checked on a regular schedule.
Choosing a match type isn't enough on its own; without a negative keyword list and a search terms report habit, some budget leaks away no matter which match type gets picked. In a discovery call with rabbitclip, the current campaign structure gets reviewed, and which match type needs changing at which stage gets worked out together.
FAQ
Is broad match always a bad idea?
No, paired with regular search terms review it's the fastest way to discover new customer phrases; left unwatched, it turns into budget waste.
