Match Types Overview
Google Ads currently has three keyword match types. Each controls the breadth of queries that can trigger your ads:
| Match Type | Syntax | Triggers When | Reach |
|---|---|---|---|
| Exact Match | [keyword] | Query is the same meaning as the keyword (with close variants) | Narrowest |
| Phrase Match | "keyword" | Query contains the meaning of the keyword phrase (with close variants) | Medium |
| Broad Match | keyword | Query is related to the keyword (AI-driven intent matching) | Widest |
An important caveat: all three match types now include "close variants" — Google will match your keywords to queries it considers equivalent in meaning even if the exact words differ. The degree of variation Google considers acceptable increases from Exact to Phrase to Broad.
Exact Match
Exact Match (syntax: [keyword]) shows ads for searches that have the same meaning or intent as the keyword. It allows close variants including: misspellings, singular/plural forms, stemming, abbreviations, accents, reordered words that don't change meaning, and addition of function words (the, a, in, for) that don't change intent.
What Exact Match still controls
- Your ad will not show for queries Google considers different in intent — "running shoes for men" will not match [women's running shoes]
- Additional words that change intent are excluded: [keyword research] will not match "keyword research tool free online" under Exact Match
- Provides the most control over spend per query and the clearest attribution between specific keywords and performance
What Exact Match no longer controls
Since 2019, Exact Match includes close variants — Google decides that "running shoes for men" and "men's running shoes" have the same intent and matches both to [men's running shoes]. This reduces exact control but generally maintains performance relevance. Check the Search Terms report regularly to see which actual queries are triggering Exact Match keywords.
Phrase Match
Phrase Match (syntax: "keyword") shows ads for searches that include the meaning of the keyword phrase. It is broader than Exact Match — additional words can appear before or after the phrase, and close variants are included. Words within the phrase can be reordered if doing so doesn't change meaning.
Phrase Match in 2026 closely approximates what Broad Match Modified (BMM) provided before its deprecation in 2021. It provides meaningful control over intent while allowing natural language variation. For most campaigns running without Smart Bidding, Phrase Match offers the best balance of volume and relevance control.
Keyword: "running shoes"
Will match: "buy running shoes online", "best running shoes 2026",
"running shoes for flat feet"
Will NOT match: "shoes for running marathon training" (reordered intent changes)
"jogging footwear" (different words, may match under Broad)
Broad Match
Broad Match (syntax: keyword — no brackets or quotes) shows ads for searches related to the keyword. Google's AI interprets the keyword's meaning and matches to queries it considers relevant — this can include synonyms, related concepts, and queries that share intent without sharing words.
Broad Match behaviour has changed significantly with the introduction of AI-driven intent matching. A Broad Match keyword "running shoes" might now trigger for "best athletic footwear for pavement running", "jogging sneakers", or "marathon training gear" — queries that share intent but share few or no words with the original keyword.
When Broad Match works well
Broad Match + Smart Bidding (Target CPA or Target ROAS) is increasingly recommended by Google for mature campaigns with sufficient conversion data. The Smart Bidding algorithm evaluates whether a given broad match expansion is likely to convert and bids accordingly — providing a safety net against unprofitable expansions that Broad Match alone cannot provide.
When Broad Match is risky
Broad Match with Manual CPC and no negative keyword discipline can quickly exhaust budget on irrelevant queries. Without Smart Bidding's conversion-probability filter and without a robust negative keyword list, Broad Match can match to queries with completely different intent.
Close Variants
Close variant matching was gradually expanded across all match types from 2014 to 2019. It now includes:
- Misspellings: "runing shoes" matches "running shoes"
- Singular/plural: "shoe" matches "shoes"
- Stemming: "run" matches "running"
- Abbreviations and accents: "US" matches "United States"; "cafe" matches "café"
- Reordered words (same intent): "shoes men running" matches "men's running shoes"
- Function word additions: "running shoes for men" matches "men's running shoes" (function word "for" added)
Close variants cannot be opted out of — they apply to all match types automatically. The only way to prevent a specific close variant from matching is to add it as an exact match negative keyword.
History of Match Types
| Year | Change | Impact |
|---|---|---|
| 2014 | Close variants for Exact and Phrase Match | Exact Match stopped being truly exact; misspellings and plurals included |
| 2019 | Exact Match expanded to same-intent queries | Reordered words and function words now match; "exact" became "same intent" |
| 2019 | Phrase Match expanded | Queries with same meaning now match phrase match even without exact words |
| 2021 | Broad Match Modified deprecated | BMM keywords auto-migrated to Phrase Match; BMM creation disabled June 2021 |
| 2021–2024 | Broad Match + Smart Bidding emphasis | Google increasingly positions Broad Match + tCPA/tROAS as the recommended default for scaled campaigns |
Search Terms Report
The Search Terms report (Keywords → Search Terms in Google Ads) shows the actual queries that triggered your ads. It is the most important tool for understanding what your keywords are actually matching — and for identifying negative keyword opportunities.
Weekly review of the Search Terms report is standard practice for well-managed campaigns. Workflow: filter for impressions > 10; sort by cost; identify queries that are irrelevant or low-intent; add those queries as negative keywords at the appropriate match type.
Note: since 2020, Google no longer shows 100% of search terms — queries with low search volume are withheld for privacy reasons. This means the Search Terms report shows a subset of actual matching queries, and some irrelevant matches may not be visible for audit.
Match Type Strategy
| Campaign Stage | Recommended Mix | Rationale |
|---|---|---|
| New campaign, exploring keywords | Phrase Match + Exact Match | Controlled exploration; search terms report reveals actual query patterns |
| Established, manual bidding | Exact Match for high-value terms + Phrase for coverage | Maximum relevance control; add negatives from search terms report regularly |
| Mature, Smart Bidding (tCPA/tROAS) | Broad Match + Smart Bidding | Algorithm filters broad expansions by conversion probability; maximises reach |
| Brand campaigns | Exact Match only | Prevents irrelevant queries; maximises brand query efficiency |
