What Are Match Types? Broad, Phrase, Exact & Modifier Guide
Learn what keyword match types are—broad, phrase, exact, and broad match modifier—and how each controls when your Google Ads appear.
What are keyword match types?
Keyword match types define how closely a user’s search query must match your keyword before your Google Ads can show. They give you control over reach vs. precision: broad match casts a wide net, while exact match targets only highly specific searches.
Choosing the right match type helps you balance traffic volume, relevance, and cost per click, so your budget is spent on clicks that actually matter.
Broad match: maximum reach
With broad match, your ad can show for a very wide range of related searches, synonyms, and variations of your keyword. Google may also include closely related terms or even different search intents, which can drive more traffic but often includes less relevant queries.
Broad match is useful if your goal is maximum visibility and discovery, but it should be heavily supported by negative keywords to filter out irrelevant searches and protect your budget.
Phrase match: controlled reach
Phrase match makes your ad appear when someone’s search contains your keyword in the same order, with extra words before or after it. For example, “running shoes” in phrase match can trigger for “buy running shoes online” or “best men’s running shoes,” but not for “shoes for running.”
This match type gives you more control than broad match while still capturing useful long tail variations that match your intent.
Exact match: high precision targeting
Exact match shows your ad only when the search query matches your keyword very closely, including close variants like plurals, misspellings, or minor rephrasing. For example, “[running shoes]” will mostly show for “running shoes” and very similar searches, not broad synonyms.
Exact match is best for high intent, conversion focused campaigns where you want to pay only for very relevant clicks and protect your quality score.
Broad match modifier (deprecated but still referenced)
Broad match modifier (BMM) used to let you require specific words in a search by adding a plus sign (e.g., +running +shoes), so at least those words had to appear—anywhere in the query—but in a less rigid way than phrase match. Google later replaced BMM with expanded keyword matching behavior inside broad match, supplemented by smart controls like negative keywords and automated keyword expansion.
Today, most best practice guides recommend using phrase, exact, and carefully managed broad match with negatives instead of relying on BMM style logic.
How to choose the right match type for your goals
• Use broad match for discovery and traffic, but pair it with strong negative keywords.
• Use phrase match to balance reach and relevance for mid funnel queries.
• Use exact match for high intent, conversion focused campaigns.
Review your search terms report regularly and refine your match type mix as you learn which terms actually convert and which ones just burn budget.
Key takeaways
• Match types control how closely user searches must match your keywords before your ads show.
• Broad match offers widest reach, exact match offers the tightest control, and phrase match sits in between.
• Combine match type discipline with negative keywords and search term analysis to keep your campaigns efficient and relevant.
