Google Ads match types control how closely a search must relate to your keyword. Broad match reaches related searches, phrase match works around meaning, and exact match covers the same meaning or intent. Choose them around the work you want, the quality of your measurement and how closely you can review enquiries.
Exact does not mean identical wording
The names can be misleading if you remember how search advertising used to work. Google’s current matching guidance describes exact match in terms of meaning or intent. It is not a promise that every query will reproduce your keyword letter for letter.
Phrase match is also based on meaning, rather than a simple requirement to contain a fixed string of words. Broad match can cover related searches beyond those narrower options. Broad, phrase and exact therefore describe different scopes, not three levels of spelling accuracy.
For an illustrative company fitting office partitions, the important question is whether the searches concern an installation service it sells. A query can use unfamiliar wording and still describe precisely that job.
What decision are you trying to control?
Start by writing down what qualifies as useful work. Include the service, type of customer, area and any firm exclusions. “We want more enquiries” is too vague to guide keyword choices.
A contractor might accept commercial projects but not domestic repairs. A training company might sell places on public courses and private courses for employers. Their matching decisions should reflect those differences, even where their keywords initially look similar.
Then ask what the landing page can explain. A broad service page may leave a specific search unanswered. A very narrow page may not serve the wider set of searches reached by a broad keyword. Match type and page choice belong in the same discussion.
A practical comparison
| Option | Useful question | Main review task |
|---|---|---|
| Exact | Which tightly defined intentions do we want to cover? | Check whether the actual searches retain the intended meaning. |
| Phrase | Which variations of this service could fit? | Look for changes in purpose, service or buying stage. |
| Broad | Can we assess a wider range of related demand? | Check relevance and downstream enquiry quality carefully. |
This is a decision aid, not a rule that one type is always cheaper or better. A narrow keyword can be expensive and unproductive. A wider keyword can find useful searches you had not written down. Your account evidence needs to settle the question.
Check what the account calls success
Google recommends pairing broad match with Smart Bidding. Review the bidding strategy and the quality of the conversion signals together before widening coverage; broader matching is not a substitute for reliable measurement.
Before widening coverage, inspect conversion actions. If the account treats a page view as equivalent to an enquiry, its reported success may have little to do with new business.
Make sure completed enquiries reach the right person and that their quality is reviewed. Record whether they match the service and area. Without that feedback, you may select keywords that generate activity while missing the work you actually want.
Do not change match types, adverts, landing pages and conversion definitions together unless you are fixing an urgent problem. A quieter change log gives you a better chance of understanding what caused the result.
Negative keywords have their own rules
Positive keywords help make a search eligible. Negative keywords exclude searches. They are not mirror images. Google’s negative keyword documentation describes different matching behaviour, including the treatment of close variants.
Build exclusions from real business boundaries and observed searches. A generic list copied from another account can block something valuable. “Training” might be irrelevant to one contractor and an important service for another.
Check whether an exclusion belongs to an ad group, a campaign or a shared list. The broader its reach, the more care it needs. Keep a reason beside unusual exclusions so somebody can understand them later.
Review actual searches, not just keyword labels
The keyword list tells you what you intended to target. The search terms report tells you more about what happened. Read it alongside costs and enquiry outcomes, allowing enough time for people to respond.
If coverage is too wide, first identify the pattern. Is it one ambiguous word, an unsuitable service, a location problem or a page that does not explain the offer? Changing every keyword to exact match may hide the symptom without resolving the cause.
If coverage is too narrow, test a clear expansion with a spending limit and a review date. Decide in advance what would justify keeping it. “More traffic” alone is not enough when the business needs suitable enquiries.
