Everything you need to know about broad, phrase, and exact match to pass the Google Ads Search exam — and actually apply it in live campaigns.
Keyword match types are one of the most tested topics in the Google Ads Search Certification — and also one of the most misunderstood in real accounts. I've audited hundreds of campaigns where broad match was doing all the heavy lifting with zero negative keywords, silently burning budget on irrelevant queries. Getting match types right is the difference between a campaign that scales and one that just spends. Here are the exam questions I'd focus on, with answers explained from a real campaign perspective.
This is a foundational match type question that appears in almost every version of the exam.
Correct answer: D. Exact match
Exact match triggers your ad when the search query matches your keyword exactly or is a close variant — which includes misspellings, singular/plural forms, and reordering of words that doesn't change meaning. In practice, I use exact match for my highest-intent, highest-converting keywords where I want full control over what triggers the ad. The tradeoff is lower volume, but the quality is consistently higher.
Google updated how broad match works significantly — this question tests whether you understand the current behaviour.
Correct answer: C. Broad match
Broad match is the widest match type — it uses Google's AI to match your keyword to queries with related meanings, synonyms, and implied intent. For example, a broad match keyword like "running shoes" could trigger for "jogging trainers" or "best footwear for marathon." In my experience, broad match only works well when paired with Smart Bidding and strong conversion data — at least 50 conversions per month. Without that signal, it burns budget fast.
Phrase match questions often involve identifying which queries are excluded — pay close attention to word order.
Correct answer: D. course for digital marketing beginners
Phrase match requires that the meaning of the keyword is preserved in the same order within the query. "Course for digital marketing beginners" breaks the phrase because "course" appears before "digital marketing" — it changes the word order of the core phrase. Options A, B, and C all keep "digital marketing course" intact with additional words around it, which phrase match allows. I see this confusion a lot when advertisers move from broad to phrase and wonder why certain queries still don't show.
Negative keywords are a core optimisation topic and feature heavily in both the exam and real account management.
Correct answer: B. To prevent ads from showing on irrelevant search queries
Negative keywords block your ads from showing when specific words or phrases appear in a search. They don't directly affect Quality Score or CPC — their job is exclusion. In nearly every account I audit, the negative keyword list is either empty or severely underdeveloped. Adding negatives consistently is the single highest-ROI optimisation task in Search campaigns — it cuts wasted spend immediately without touching bids or budgets.
This question tests your understanding of how match types interact with Smart Bidding — a commonly tested combination.
Correct answer: C. Broad match paired with Smart Bidding
Google's official recommendation — and what the exam reflects — is to use broad match alongside Smart Bidding strategies like Target CPA or Target ROAS. The idea is that Smart Bidding's auction-time signals (device, location, time, user intent) compensate for the wider net that broad match casts. In practice, I agree with this approach but only when the account has strong conversion history. If you're starting fresh, use exact and phrase match first to build clean data, then layer in broad match once Smart Bidding has enough signal to work with.
Running Google Ads Search campaigns and not sure your match types are set up correctly? A mismatched keyword strategy is one of the most common — and costly — mistakes I fix in account audits.
