Match Types and Negative Keywords

Updated: November 13, 2026 · Leer este capítulo en español

Your keywords do not decide exactly which searches trigger your ads. Google Ads match types do, and they are looser than most owners expect. This chapter explains broad, phrase and exact match as they work today, why broad match only makes sense with smart bidding and real conversion data, how to read the search terms report, and how to build the negative keyword lists that stop paying for jobs, DIY tips and the wrong side of town. It ends with a 20-minute routine to repeat every week.

What Google Ads match types mean today

When you add the keyword ac repair hialeah to your account, you are not telling Google "show my ad only when someone types exactly these three words." You are telling it "show my ad for searches that match this keyword," and the match type sets how loose that match can be.

In the early years of Google Ads, match types were mostly about words: whether the search contained your words, in your order, with or without extras. That is no longer how they work. Google now matches by meaning. According to Google's page on keyword matching options, even exact match can show your ad on searches with the same meaning or the same intent as your keyword, not only identical text. Small differences in wording, a plural, a misspelling or a different word order can all count as "the same."

This is good news and bad news. Good, because you no longer need to list every spelling and plural. Bad, because Google's idea of "the same meaning" is not always yours. To Google, "ac repair" and "ac repair training" may look close. To the owner of an HVAC company, one is a customer and the other is a student. That gap is what this chapter is about.

Broad, phrase and exact match, side by side

There are three match types. You choose them with simple symbols when you type the keyword:

The examples are illustrations of how matching tends to behave, not a guarantee of what Google will match in your account. That uncertainty is exactly why you will check real searches every week.

Some useful facts from Google's documentation:

• Broad match is the default. If you type a keyword without quotes or brackets, it is broad. Many owners run broad match for months without knowing it.
• Broader types include the narrower ones. A phrase match keyword covers the searches its exact version would, and broad covers both. Adding the same words in all three types does not triple your reach.
• Broad match looks beyond the keyword. Google says it can take into account the person's recent searches, the content of your landing page and assets, and the other keywords in the ad group.

For a new local account with a modest budget, a sensible starting point is phrase and exact match for your core services. They give you more control while you learn which searches bring customers. Broad match can come later, deliberately, as the next section explains.

Why broad match needs smart bidding and conversion data

Google's own guidance is direct: "It's critical to use Smart Bidding with broad match." That line, from Google's keyword matching page, explains a lot about how the system is designed.

Smart Bidding is Google's name for automated bidding strategies, such as Maximize conversions or Target CPA, that set a bid for each individual auction based on how likely that search is to lead to a conversion. Broad match casts a wide net; Smart Bidding is supposed to decide, search by search, which fish are worth paying for. The two are meant to work together.

Here is the catch that professionals understand and beginners often learn the hard way: Smart Bidding learns from your conversions. If you have no conversion tracking, or it counts the wrong things, or you only get a handful of conversions a month, the system has very little to learn from. Broad match then keeps widening the net, and the bidding cannot tell good searches from bad ones. The result is a lot of clicks from loosely related searches and a budget that disappears fast.

So before you turn on broad match, ask three questions:

1. Is conversion tracking working and tested? Calls and forms, counted once each, as set up in Chapter 2.
2. Are you getting conversions regularly? Not one or two a month, but a steady flow the system can learn from.
3. Are you using a Smart Bidding strategy? Broad match with manual bids or "maximize clicks" removes the safety net Google itself says it needs.

If the answer to any of these is no, stay with phrase and exact for now. We look at the bidding strategies in detail in Chapter 6. Note that, at the time of writing, Google is renaming some of these strategies in the interface, so the labels you see may differ slightly from the ones in this book.

The search terms report: where the truth lives

Your keywords are what you asked for. The search terms are what people actually typed before seeing and clicking your ad. The search terms report lists those searches, with clicks, cost and conversions for each one. If you only look at one report in Google Ads, make it this one.

Reading it is simple. For each search term, ask: would I have paid for this click if I had seen the search first?

• Yes, and it brought calls or forms: consider adding it as its own keyword, so you can bid on it and write an ad for it directly.
• Yes, but no results yet: leave it alone and look again next week.
• No: add a negative keyword that blocks it and others like it.

Two things to know. First, the report does not show every single search. Google explains that searches without enough volume are left out to protect user privacy, and may appear grouped into broader themes or as "other" searches. Second, the report is most valuable early on. In the first weeks of a campaign it shows how Google interprets your keywords, and that is when the costly mismatches show up.

For our example dental office in Doral (an illustration, not a client), a first look at the report might show useful searches like "dentist open saturday doral" next to wasted ones like "dental assistant jobs doral," "free dental clinic miami" or "dentist in coral springs," a city in Broward County well outside the office's area. Each wasted search is a lesson and a negative keyword.

Building negative keyword lists

Negative keywords stop your ad from showing when a search contains them. They are the brakes of your account. You can add them to a single ad group, to a whole campaign, or to a list that you apply to several campaigns at once. Google also offers an account-level list that applies to all eligible search inventory in the account.

You do not have to wait for the search terms report to start. Most local businesses can build a first list before launch, using the intent groups from Chapter 3:

For the Cuban restaurant in Little Havana, a "wrong services" list might include recipe, receta, cookbook and "near me" searches for other cuisines that slipped in through broad matching. For the dental office, it might include insurance plans it does not accept, or veterinary searches if "dental" keywords start pulling in "dog dental cleaning."

What pros do: they keep negatives in a few named, shared lists ("Jobs," "DIY," "Wrong services," "Wrong places") instead of scattering them across ad groups. When a new campaign launches, the lists are applied in a minute, and nobody pays twice to learn the same lesson.

How negative keywords match (and the traps)

Negative keywords use the same three symbols as regular keywords, but they behave differently, and the differences cause real mistakes. Here is what Google's negative keyword page explains:

The traps:

• Negatives do not expand to close variants. Google says you need to add synonyms and singular or plural versions yourself; blocking "job" does not block "jobs." (Google notes that casing and misspellings are handled for you.)
• Too many words in one negative weakens it. A negative broad keyword like free ac repair course only blocks searches containing all four words. Usually you want the single word course.
• Negatives can block your best customers. Adding "emergency" as a negative because one emergency search looked odd could shut off your most valuable calls. Before adding a single-word negative, ask whether that word ever appears in a search you want.
• Check for conflicts. If a negative blocks one of your own keywords, that keyword stops showing. The platform may warn you about some conflicts, but do not count on it: check new negatives against your keyword list.

A weekly 20-minute cleanup routine

Campaigns drift. New searches appear, seasons change, Google tests new matches. The defense is not a big monthly overhaul; it is a short, boring routine done every week. Here is one that fits in twenty minutes for a small account:

1. Minutes 1–3: check the basics. Did the campaign spend roughly what you expected? Are there calls and forms recorded? Any disapproved ads or warnings?
2. Minutes 4–12: read the search terms from the last 7 days, sorted by cost. Start with the most expensive ones. For each, decide: keep, add as keyword, or block.
3. Minutes 13–16: add negatives to the right list. Single words for whole categories (jobs, course), phrase or exact for specific searches you want to block without collateral damage.
4. Minutes 17–19: add winners as keywords. Searches that brought real calls deserve their own phrase or exact keyword in the right ad group.
5. Minute 20: write one line in a log. Date, what you changed and why. In three months, that log will explain your results better than any report.

In the first month, do this twice a week; that is when most waste shows up. After that, once a week is usually enough for a small local account. If you notice the same kind of junk search coming back week after week, that is a sign a keyword is too broad and should be tightened, not just patched with negatives.

If twenty minutes a week is twenty minutes you do not have, that is a reasonable thing to hand off; it is the core of what our PPC management in Miami does each week. Either way, once the right searches are reaching you, the next job is making sure the ad they see is worth clicking: Chapter 5.
