Broad, Phrase or Exact: Which Negative Keyword Match Type Should I Use?

You've found a junk query in your search terms report, ticked the box, and Google Ads wants a match type for the negative. Pick too loose and you block searches that convert. Pick too tight and the same junk keeps arriving in slightly different wording. Your instincts from positive keywords won't help, because negatives match differently.

Use phrase match for most negatives. It blocks the unwanted words wherever they appear in a query and leaves the useful searches around them alone. Use exact match to route one query to a different ad group or to cut a single underperformer. Use broad match for word combinations that are irrelevant in any order. None of the three catches plurals, misspellings or synonyms, so add those yourself.

What does each negative match type block?

Suppose you sell new laptops and want to stop paying for second-hand shoppers. Here is how each match type handles a negative for "used laptops":

• Broad negative: blocks any query that contains both words, in any order, with anything around them. "Cheap used laptops" is blocked. "Laptops used by students" is also blocked, though it might be a perfectly good query.
• Phrase negative: blocks any query that contains "used laptops" in that order, with other words allowed before or after. "Cheap used laptops UK" is blocked. "Laptops used by students" still shows.
• Exact negative: blocks only the query "used laptops" on its own. "Cheap used laptops" still shows.

The trap is the word "broad". A broad match keyword reaches plurals, misspellings, synonyms and related searches. A broad match negative does none of that. It only negates the exact spellings of its words, as long as each one is present somewhere in the query. "Used laptop", singular, gets past all three negatives above. "Pre-owned laptops" does too. Every negative match type is literal, and broad negatives are only loose about word order.

That one fact explains most negative keyword mistakes. Advertisers add a broad negative expecting it to sweep up a whole topic, and the variants keep spending. Or they add an exact negative expecting it to cover a theme, and it blocks one string while the long tail carries on.

Why phrase match should be your default

Most wasted spend comes from a concept that appears inside otherwise varied queries. Think of "free", "jobs", "salary", "how to", a product line you don't stock, or a city you don't serve. You want to block that concept wherever it turns up, whatever the searcher typed around it. Phrase match does exactly this.

That matters because you will never see every variation. Low-volume queries often don't appear in the search terms report at all, so a negative that only blocks what you've already seen leaves you exposed to everything you haven't. A phrase negative on the problem words covers the variants before they show up. When you're deciding which search terms deserve blocking in the first place, this is why the useful unit is the offending fragment, not the full query.

Phrase also beats broad on multi-word negatives, because order often carries the meaning. "Repair laptop" means a service. "Laptop repair kit" might be a product you sell. Phrase lets you block one without touching the other.

For single-word negatives the choice disappears. A one-word broad negative and a one-word phrase negative block exactly the same queries, because there is no order to respect. Either label works.

When should a negative be exact match?

Exact negatives do two jobs well, and neither is general cleanup.

Routing a query to the right ad group

Say "business laptops" earns its own ad group, with tailored copy and a dedicated landing page. That query can still be picked up by a broader ad group in the same account. If it is, your generic ad serves and the work you put into the dedicated one is partly wasted.

The fix is to add [business laptops] as an exact negative in the broader ad groups. They keep every longer query, such as "business laptops with long battery life", and hand the exact query to the ad group built for it. Phrase or broad would strip those longer queries out too, which is not what you want.

Cutting one loser without collateral damage

Sometimes a specific query spends without converting, but its words also appear in queries that do convert. "Laptop deals" might burn budget while "gaming laptop deals" pays for itself. A phrase negative on "laptop deals" would kill both. An exact negative removes only the loser.

Before you negate anything, ask whether the query is junk or just mismatched. If someone searches for a model you've discontinued, an ad pointing to its replacement may beat a negative, budget permitting. A negative removes the traffic. A better ad might convert it.

When does a broad negative earn its place?

Broad negatives make sense when a combination of words is wrong in any order, and the individual words are fine on their own. If you sell laptops but don't repair them, a broad negative on "laptop repair" blocks "laptop screen repair", "repair my laptop" and "who repairs laptops near me". A phrase negative would miss all three, because the words aren't adjacent and in order.

The risk is the reverse of phrase. Broad negatives over-block when the same words form useful queries in a different arrangement, as "laptops used by students" showed earlier. Use broad when you've checked that no worthwhile query combines those words. Otherwise, use phrase and accept that you'll add the odd extra negative.

How do you choose from the search terms report?

When you're looking at a bad query, work through it in this order:

1. Find the part that makes it wrong. In "free laptop recycling near me", the problem is "free" or "recycling", not the whole string. Negate the fragment, not the query.
2. Is it a single word or a fixed phrase? Use phrase match. This covers most of what you'll add.
3. Are the words wrong together in any order, but fine apart? Use broad match.
4. Is only this exact query wrong, or does it belong in another ad group? Use exact match.
5. Add the variants by hand. Include plurals, common misspellings and obvious synonyms, because no negative match type adds them for you.
6. Test for collateral damage. Before saving, run the candidate negative against your recent converting search terms. If it would have blocked any of them, tighten the match type.

That last step is the one most people skip, and over-blocking is the more expensive mistake. Junk that gets through shows up in the next report. A negative that blocks good traffic just shrinks your reach, with nothing in the report to flag it.

The match type is only half the decision. The other half is whether the negative belongs on the account, a campaign or a shared list. A good phrase negative applied at the wrong level either misses campaigns it should cover or blocks ones that need the traffic.

Conclusion

Negative match types are narrower than the positive match types they share names with, and that shapes every choice. Phrase is the right default because it blocks a concept wherever it appears without guessing at meaning. Exact handles routing and surgical cuts. Broad is for word combinations that are wrong in any order. The real discipline is upstream and downstream: isolate the fragment that makes a query wrong, add the variants no match type will catch, and check every negative against what already converts before you commit it.
