Matchtype (also called keyword match type) controls how closely a user's search query must align with your keyword before your ad enters the auction. These settings determine whether your ads appear for exact terms, phrases containing your meaning, or broader related searches. Selecting appropriate match types balances campaign reach against relevance, directly affecting your return on ad spend (ROAS) and cost efficiency.
What is Matchtype?
Matchtype is a targeting mechanism used in search engine advertising (SEA), particularly within Google Ads, to define which search queries can trigger your advertisements. Depending on the option selected, your ads may appear for a wide range of related queries or only for specific, high-intent searches.
Syntax determines the match type:
- Broad match: Input the keyword without punctuation (e.g., women's shoes)
- Phrase match: Enclose the keyword in quotation marks (e.g., "women's shoes")
- Exact match: Place the keyword in square brackets (e.g., [women's shoes])
- Negative match: Add a minus sign before the keyword (e.g., -cheap)
Some older documentation references a modified broad match (using a plus sign such as +women's +shoes), which required specific terms to be present in close variant form. This variation is not present in current Google Ads guidance.
Why Matchtype matters
- Control spend and prevent waste: Negative keywords exclude irrelevant traffic before it consumes budget, ensuring you pay only for qualified clicks.
- Balance reach with precision: Broad match captures discovery traffic and related searches, while exact match hones in on converters, allowing strategic budget allocation.
- Improve efficiency with automation: Broad match provides the wide query set necessary for Smart Bidding algorithms to optimize auction-time bids based on contextual signals.
- Simplify account management: Broader match types automatically capture close variants (misspellings, plurals, abbreviations), reducing the need to build exhaustive keyword lists.
- Optimize for ROAS: Phrase and exact matches typically deliver higher conversion rates by targeting specific user intent, improving your return on investment.
How Matchtype works
Matchtypes function within a hierarchy where broader types encompass narrower ones. Broader match types capture all the queries of narrower match types, plus more. For example, a phrase match keyword triggers ads for all exact match queries of that keyword, plus additional searches containing your phrase's meaning. A broad match keyword triggers ads for all equivalent phrase and exact matches, plus related searches determined by Google's AI.
The mechanism considers: - Close variants: All match types account for misspellings, singular/plural forms, abbreviations, acronyms, and word stems. - Query context: Broad match evaluates user search activities, landing page content, and other keywords in the ad group to determine relevance. - Auction dynamics: When multiple keywords from your account match a query, the system selects one based on Ad Rank, not keyword specificity.
Broad match is the default match type assigned to all keywords. You do not need to specify syntax to use it.
Types of Matchtype
| Type | Syntax | Triggers when | Best used for |
|---|---|---|---|
| Broad | keyword |
Search is related to your keyword; may include terms without the direct meaning | Maximum reach, traffic generation, brand awareness |
| Phrase | "keyword" |
Search includes the meaning of your keyword; can be a more specific form | Balanced targeting, capturing qualified variations |
| Exact | [keyword] |
Search has the same meaning or same intent as the keyword | Precise control, high-intent conversion capture |
| Negative | -keyword |
Excluding searches containing this term | Preventing irrelevant impressions and clicks |
Best practices
Pair broad match with Smart Bidding. It is critical to use Smart Bidding with broad match because every search query is different, and bids should reflect unique contextual signals present at auction-time. Smart Bidding ensures you compete in the right auctions at the right bid for the right user.
Review search term reports weekly. Identify actual queries triggering your ads to find new negative keywords and high-performing exact match opportunities. Continuous comparison of click-through rates (CTR) for individual keywords is advisable when using broad match to catch keyword contamination early.
Avoid adding near-duplicate keywords. Adding very similar keywords, such as "red car" and "car red," is not recommended because only one keyword would match both searches. The system recognizes these as duplicates and uses the higher Ad Rank version; adding both provides no benefit.
Combine multiple match types strategically. Google recommends combining multiple keyword options to keep track of target group size while maintaining high relevance. Segment effective keyword options at campaign or ad group levels to optimize by CTR, especially for small budgets.
Use negative keywords proactively. Exclude terms that indicate unqualified traffic (e.g., "free," "jobs," or competitor names you don't want to match) to prevent spend waste.
Common mistakes
Mistake: Using broad match without Smart Bidding enabled. Fix: Enable Smart Bidding immediately; without it, you lack auction-time bid adjustments for the wide variety of queries broad match captures.
Mistake: Assuming adding similar keywords increases coverage. Fix: Remove duplicates like "running shoes" and "shoes running"; only one will serve based on Ad Rank, and you'll still only have one bid in the auction.
Mistake: Ignoring the search terms report. Fix: Check bi-weekly for queries with high impressions but low CTR; add these as negative keywords to prevent keyword contamination.
Mistake: Using special characters in keywords. Fix: Remove symbols like !, @, %, or *; the system reserves these and they should not appear in keyword options.
Mistake: Creating capitalized and lowercase versions of the same keyword. Fix: Delete duplicates; Google Ads is not case-sensitive, so "Shoes" and "shoes" function identically.
Examples
Example scenario: A premium luggage retailer wants to balance volume and precision.
- Broad match:
luxury travel bagscaptures "designer carry-on luggage," "high-end weekend bags," and "business class travel accessories." - Phrase match:
"luxury travel bags"captures "buy luxury travel bags" and "luxury travel bags leather." - Exact match:
[luxury travel bags]captures searches with that specific intent and close variants like "luxury travelling bag." - Negative match:
-cheap,-discount,-freeexclude bargain hunters looking for budget options.
FAQ
Does match type affect my cost-per-click?
Indirectly. Broader match types may show for less relevant queries, potentially lowering your CTR and Quality Score, which can increase costs. Exact match typically delivers higher relevance and conversion rates. Smart Bidding helps manage costs across all match types by setting bids per auction rather than per keyword.
Can I use the same keyword with different match types in one campaign?
Yes. While broader match types technically capture narrower queries, using multiple match types allows you to assign different bids. For example, bid higher on exact match keywords where you have proven conversion data, and lower on broad match for discovery traffic.
Are match types case-sensitive?
No. Keywords are not case-sensitive. "Running Shoes" and "running shoes" trigger identical results.
What are close variants?
Close variants include misspellings, singular and plural forms, abbreviations, acronyms, word stems, and accents. These are automatically included in match behavior unless specifically excluded by negative keywords.
How do I see which actual queries triggered my ads?
Run the Search Terms Report (or search query report). This reveals the exact text users typed that matched your keywords, helping you identify new negative keywords or promising exact match additions.
What is the difference between broad match and modified broad match?
Modified broad match (syntax: +keyword) required specific words to be present in close variant form but excluded synonyms. Google retired this type in 2021, incorporating its behavior into phrase match. Some documentation may still reference it for historical accounts.
