What are match types and why do they matter?
When you add a keyword to your Google Ads campaign, the match type tells Google how closely a person's search needs to match that keyword before your ad is eligible to show. A loose match type means your ad can show for a wide range of searches. A tight match type means it only shows for very specific ones.
This matters enormously for budget efficiency. If you are running a tight budget and your match types are too loose, you will spend money on searches that have nothing to do with what you sell. If your match types are too tight, you might miss relevant searches and not spend your full budget.
There used to be four match types in Google Ads. Broad match, broad match modifier, phrase match and exact match. Broad match modifier was removed in 2021 and its behaviour was rolled into phrase match. So in 2026 there are three match types to understand.
The three match types
What it does: Shows your ad for searches that Google considers related to your keyword. This includes synonyms, related topics, misspellings and searches that don't contain any of your keyword's words at all.
How it works in 2026: Broad match is significantly more powerful than it used to be because it now uses signals from the rest of your campaign to decide when to show. Your landing page, ad copy and other keywords in the ad group all influence what searches trigger your broad match keywords.
When to use it: Broad match works well in accounts with good conversion data and smart bidding active. The algorithm can use conversion signals to figure out which of the wide range of searches are actually worth showing for. In accounts without much data, or using manual bidding, broad match tends to waste budget fast.
The risk: Without a solid negative keyword list, broad match will inevitably show your ads for irrelevant searches. This requires more active management than the other match types.
What it does: Shows your ad for searches that include the meaning of your keyword. Words can appear before or after your keyword phrase, and close variants including misspellings and singular or plural versions are included.
How it works in 2026: Since the removal of broad match modifier, phrase match absorbed some of BMM's tighter behaviour. It is more restrictive than broad match but more flexible than exact. The order of words in the keyword doesn't need to be preserved, but the core meaning does.
Would NOT show for: jogging trainers, sport footwear
When to use it: Phrase match is the most versatile match type for most accounts. It gives you reasonable control over what your ads show for while still capturing variations and word order differences that exact match would miss. It is a good default for accounts that want control without being overly restrictive.
The risk: It is still broader than exact match, so regular search term reviews are important to catch anything irrelevant slipping through.
What it does: Shows your ad only when someone searches for your exact keyword or a very close variant of it. Close variants include misspellings, singular and plural forms, abbreviations and reorderings of words with the same meaning.
How it works in 2026: Exact match is no longer truly exact in the way it used to be. Google's close variants mean a search for "shoes for running" could trigger an exact match keyword of [running shoes] because Google determines the meaning is the same. This is more permissive than the old exact match behaviour, which many advertisers didn't welcome.
Would NOT show for: best running shoes, cheap running shoes, trail running shoes
When to use it: Exact match is best for your highest-value keywords where you know precisely what someone needs to search to be a good prospect. It gives you the most control over spend and makes it easier to see exactly which searches are driving results.
The risk: You can miss relevant searches by being too restrictive, particularly longer tail variations that convert well but wouldn't trigger exact match keywords.
How the match types compare
| Match type | Reach | Control | Best for |
|---|---|---|---|
| Broad match | Widest | Lowest | Large budgets, strong conversion data, smart bidding |
| Phrase match | Medium | Medium | Most accounts as the primary match type |
| Exact match | Narrowest | Highest | High-value specific keywords, tight budgets |
What has changed in recent years
Match types have loosened considerably over the past few years and it is worth knowing about if your understanding of them is based on how they worked before 2020.
Broad match modifier was removed in 2021. The plus sign syntax that used to lock individual words into a match is no longer supported. Phrase match absorbed much of what BMM did, though it is still broader than the old BMM behaviour in some cases.
Close variants have expanded significantly for both phrase and exact match. Google now considers searches with the same meaning as close variants, not just obvious misspellings and plurals. This means exact match in particular is less restrictive than it used to be.
Broad match has become more intelligent. It now uses signals from across your campaign to determine relevance, rather than just looking at the keyword in isolation. This makes it more viable than it was a few years ago, particularly in accounts with smart bidding active.
The general direction of travel: Google has been consistently moving towards broader match types and more algorithmic control over when ads show. Negative keywords have become more important as a result, because they are now one of the primary tools for excluding irrelevant traffic that looser match types might otherwise capture.
How to use match types in practice
For most small to medium accounts
Start with phrase match as your primary match type. It gives you a reasonable balance of reach and control. Use exact match for your most important keywords where you know exactly what search terms you want to capture. Build a negative keyword list from day one and add to it weekly based on your search terms report. This is especially relevant for B2B accounts, where search volume is naturally lower and every click needs to count.
Hold off on broad match until you have solid conversion data and are running smart bidding strategies. Then test it carefully, ideally in a separate campaign so you can compare performance.
For larger accounts with conversion data
Broad match with Target CPA or Target ROAS bidding can work very effectively once the account has enough conversion data for the algorithm to optimise against. The combination of broad match reach and smart bidding efficiency can open up search volume that phrase and exact match campaigns miss.
Even in this setup, a comprehensive negative keyword list at account level is essential to prevent the most obviously irrelevant searches from getting through.
Negative keywords matter more than ever
As match types have loosened, the importance of negative keywords has increased in proportion. A well-maintained negative keyword list is one of the most effective tools for controlling what your ads show for across all match types. Without one, even phrase and exact match can produce surprising search term results.
Review your search terms report at least weekly, particularly for phrase and broad match keywords. Add anything irrelevant as a negative at the appropriate level. Over time this builds into a valuable exclusion list that improves the efficiency of the whole account.
Common mistakes with match types
- Using only broad match on a small budget. Without enough data for smart bidding to work well, broad match burns through limited budgets quickly on irrelevant searches.
- Using only exact match everywhere. You will miss relevant searches and often struggle to spend your full budget, particularly for lower-volume keywords.
- Not reviewing search terms regularly. Match types are not a set-and-forget decision. What triggers your ads changes over time as Google updates its algorithms and as search behaviour shifts.
- No negative keywords. Running any match type without a negative keyword strategy is like having a broad match account with no guardrails.
- Mixing match types for the same keyword in the same ad group. Having running shoes, "running shoes" and [running shoes] all in the same ad group creates internal competition and muddies your performance data.
Common Google Ads keyword status questions
What does "not eligible" mean for a Google Ads keyword?
It means the keyword currently cannot trigger your ad, even though it is switched on. This usually happens because of a policy issue, an ad approval problem, or another setting elsewhere in the account blocking it from showing.
What does "rarely served" mean in Google Ads?
It means Google expects very little or no search volume for that specific keyword. This is often because it is too narrow, too similar to another keyword already in your account, or genuinely low volume.
What does "below first page bid" mean?
It means your current bid is too low for your ad to typically appear on the first page of results for that keyword. Raising your bid, or improving your quality score, usually helps.
Why does my keyword say "campaign paused"?
This means the entire campaign the keyword belongs to has been paused, not just the keyword itself. Every keyword in a paused campaign will show this status until the campaign is switched back on.
What does "low quality" mean for a keyword?
It means Google's quality score system has flagged a problem with the keyword's relevance, expected click through rate, or landing page experience. This can reduce how often your ad shows and how much you pay when it does.
The bottom line
Match types are one of the most fundamental decisions in any Google Ads account and they have a direct impact on how efficiently your budget is spent. Phrase match is the most practical starting point for most accounts. Exact match gives you the most control for your most important keywords. Broad match can be powerful but needs the right conditions to work well.
Whatever match types you use, a regular search terms review and an active negative keyword list are non-negotiable. They are what keeps your account efficient as match types continue to evolve.
If you are unsure how your current match type setup is affecting performance, a proper account audit will show you exactly where your budget is going and whether the right people are seeing your ads, whether you're working with a PPC consultant in London or managing the account yourself. A contract Google Ads specialist reviewing match types as part of a wider audit will usually catch far more than a one-off keyword cleanup would.
