Keyword match types control how closely a search has to match your keyword before your ad is eligible to show. Getting this wrong is one of the fastest ways to either waste budget on irrelevant clicks or miss valuable searches entirely.
Broad Match: The Widest Net
Broad match shows your ad for searches Google considers related to your keyword’s meaning — not just similar wording. A broad match keyword like “women’s shoes” might show for “ladies footwear” or even “best gifts for her,” depending on Google’s interpretation. It reaches the most people, but also carries the highest risk of showing for searches that aren’t actually relevant to what you sell.
Phrase Match: The Middle Ground
Phrase match (written with quotation marks, like “women’s shoes”) requires the core meaning and word order of your phrase to be present, though extra words can appear before or after. This is often the best starting point for small budgets — wide enough to catch real variation in how people search, narrow enough to stay relevant.
Exact Match: The Tightest Control
Exact match (written with brackets, like [women’s shoes]) shows your ad only for searches with the same meaning as your exact keyword, with very little variation allowed. This gives you the most control and typically the highest relevance, but the smallest reach — useful once you know precisely which searches convert.
A Practical Approach for a New Campaign
Start with phrase match for your core keywords. It’s forgiving enough to catch real search variation without the unpredictability of broad match. As you gather data, add negative keywords (searches you explicitly don’t want to show for) to tighten things further, and consider adding exact match versions of your best-performing phrase match keywords once you’ve identified them.
Don’t Forget Negative Keywords
Regardless of match type, review your “search terms report” weekly — this shows the actual searches that triggered your ads. Add irrelevant or low-intent searches as negative keywords so your budget stops being spent on them. This one habit, done consistently, often improves campaign performance more than any single change to bids or match types.
There’s no single “correct” match type — the right choice depends on your budget, how well-defined your keywords are, and how much time you have to monitor and refine the campaign. When in doubt, start narrower than feels comfortable; it’s easier to expand a working campaign than to rescue one that’s bled budget on irrelevant clicks.
