Negative Keywords in Google Ads: How to Stop Paying for Clicks That Never Call You

2026-10-27 · by Lin Zeri

Google bills you when someone clicks your ad. It does not ask whether that person wanted to hire you, apply for a job, fix the problem themselves or buy a part. If your ad shows for a search that has nothing to do with your business, you can still pay for the click.

Negative keywords are the tool that closes that gap. This guide explains what they are, how to find the searches worth blocking, which types of searches local service businesses usually block, how the three match types work, and a simple routine for keeping the list current. It makes no promise about how much you will save, because no trustworthy number exists for that.

Key Takeaways

  • A negative keyword tells Google which search terms should not trigger your ads.
  • The search terms report shows the real searches behind your clicks. That is where your negative keyword list should come from.
  • Negative keywords come in broad, phrase and exact match, and each one blocks a different set of searches.
  • Block carefully: a word that looks useless can also appear in searches from real customers.
  • Review the report on a recurring schedule, because new searches keep appearing.

What Is a Negative Keyword?

A negative keyword is a word or phrase that tells Google not to show your ad when someone searches for it. Google's own definition is short: "Negative keywords let you exclude search terms from your campaigns" (Google, "About negative keywords", Google Ads Help, accessed Oct. 2026).

Regular keywords say "show my ad for searches like this." Negative keywords say "do not show it for searches like that." Together they shape who sees your ad.

Think of a pest control company. It wants to show up when someone needs help at home, not when someone is searching for a job in pest control. Without a negative keyword, the ad can appear for both.

Why Do Irrelevant Searches Cost You Money?

Because you pay per click. Google explains the limit on that cost this way: "If someone clicks your ad, that click won't cost you more than the maximum cost-per-click bid (or "max. CPC") that you set" (Google, "About maximum CPC bidding", Google Ads Help, accessed Sep. 2026). The click is charged whether the person was a customer or not.

The price per click comes from an auction. Google says "How much you actually end up paying is often less" than your maximum, and the auction weighs "The context of the person's search" (Google, "About Ad Rank", Google Ads Help, accessed Oct. 2026). The cost of a click varies, but the logic does not: a click on an irrelevant search is paid for with no chance of a job.

How Do You Find Which Searches to Block?

Open the search terms report in your Google Ads account. It shows the actual searches that triggered your ads, which can be very different from the keywords you chose. Your keywords are your guess. The report is what really happened.

Read it with one question in mind: if this person had called me, would I want the call? Go through the list and sort each search into one of three groups:

  1. Wanted. The person clearly needs what you sell, in the place you serve. Leave these alone.
  2. Unwanted. The search is about something you do not offer, a place you do not serve, or a goal that is not hiring you. These are your negative keyword candidates.
  3. Unclear. Leave these for now and look again when you have more data.

For an unwanted search, ask which word makes it unwanted. Often one word explains a whole family of searches.

If the report shows plenty of searches that match your service but still no calls, the problem may not be the keywords at all. Google describes Quality Score as "a diagnostic tool to identify how ads that show for certain keywords affect the user experience," built from "Expected clickthrough rate (CTR), Ad relevance, Landing page experience" (Google, "About Quality Score for Search campaigns", Google Ads Help, accessed Oct. 2026). Our guide to Quality Score for local businesses explains how to use it, and what to do with the leads you get covers the part after the phone rings.

Which Searches Does a Local Service Business Usually Block?

Most local service businesses end up blocking the same five kinds of searches. The examples below are an illustration only, not a recommended list. Your own search terms report is the real source, and the right words depend on your trade, your city and what you decline to do.

Kind of searchWhy it rarely becomes a customerIllustrative example terms
Job seekersThe person wants employment, not your servicejobs, hiring, careers, salary
Do it yourselfThe person wants to solve it alonediy, how to, tutorial, kit
Free or cheapestThe person is not looking to hire a companyfree, coupon, cheapest
Wrong serviceYou do not offer it, even though the words overlapa related service you decline
Wrong areaOutside the cities you servenames of cities you do not cover

Two notes. Be careful with "free": if you offer a free estimate or a free diagnosis, a customer may search for "free estimate" and be exactly who you want. Block the specific phrases that signal the wrong intent, not a word that also appears in your offer. And for the wrong area, location settings are the first place to look, with negative place names as a second layer.

What Do the Three Match Types Do?

A negative keyword has a match type, and the match type decides how much it blocks. Google lists three. Broad is the default for negative keywords: "This type is the default for your negative keywords" (Google, "About negative keywords", Google Ads Help, accessed Oct. 2026).

  • Broad. Google says "your ad won't show if the search contains all your negative keyword terms," and adds "even if the terms are in a different order." The search has to contain every word of your negative keyword, in any order.
  • Phrase. Google says "your ad won't show if the search contains the exact keyword terms in the same order." The search can include other words as well.
  • Exact. The ad does not show when the search contains the exact keyword terms in the same order with no extra words. If the search adds words, the ad may still show. This is the narrowest of the three.

In practice, a one word negative blocks every search that contains that word. A longer negative blocks only searches that contain all of its words, so it is more precise. Use a single word when it is unwanted almost everywhere. Use a longer phrase or exact match when the word is risky on its own. Do not assume one entry covers every variation of a phrase: check the report again to see what still gets through.

Where Do You Add Negative Keywords?

Google's help page is titled "Add negative keywords to ad groups, campaigns, and negative keyword lists," and it also covers adding them at the account level (Google, "Add negative keywords to campaigns", Google Ads Help, accessed Oct. 2026). That gives you three places to work with:

  • Ad group or campaign. For words that apply only to one service or one campaign.
  • Negative keyword list. A saved list you can reuse across several campaigns.
  • Account level. For words you never want, in any campaign.

The simple rule: block at the broadest level where the word is truly unwanted. A job-related word probably belongs on a shared list. A word that is unwanted for one service but fine for another belongs at the campaign or ad group level.

How Do You Avoid Blocking Good Customers?

Negative keywords can backfire when they are too broad. Before you add one, ask whether a paying customer could type it.

  • Check the report first. If the word appears in searches that look like real customers, do not add it as a broad negative.
  • Prefer phrases to single words when a word has two meanings.
  • Do not copy a list from the internet. Your trade, your city and your services decide what is unwanted.

Blocking too little wastes clicks. Blocking too much hides real demand.

What Is a Simple Review Routine?

The list is never finished, because people keep searching in new ways. Put a recurring reminder on your calendar. How often depends on how much you spend and how many searches your ads get. The routine itself is short:

  1. Open the search terms report for your campaigns.
  2. Sort each search into wanted, unwanted or unclear.
  3. Find the word that makes an unwanted search unwanted.
  4. Choose the match type and the level (campaign, list or account).
  5. Add it and write it down with the reason.
  6. Look at the wanted searches too. If they bring clicks but no calls, check your ad and landing page.

If you want ideas for new keywords as well, Google says Keyword Planner "helps you research keywords for your Search campaigns" (Google, "Use Keyword Planner", Google Ads Help, accessed Oct. 2026). It requires finishing your account setup with billing information to access the basic features.

Frequently Asked Questions

What is a negative keyword in Google Ads?

It is a word or phrase that keeps your ad from showing for searches that contain it. Google describes negative keywords as a way to exclude search terms from your campaigns.

How do I find negative keywords for my business?

Open the search terms report in your Google Ads account and read the real searches that triggered your ads. Any search that is about a job, a service you do not offer or a place you do not serve points to a word worth blocking.

What is the difference between broad, phrase and exact match for negative keywords?

Broad blocks a search that contains all your negative terms in any order. Phrase blocks a search that contains the terms in the same order, even with other words around them. Exact blocks a search that contains the terms in the same order without extra words, so it is the narrowest.

Will negative keywords lower my cost?

They stop your ads from showing for searches you have decided are not worth a click, but no source gives a number for how much that changes your spend. Treat them as a way to keep the budget for relevant searches, not as a savings promise.

What Should You Do Next?

Open your search terms report today and read it as a customer-or-not list. Pick the three clearest unwanted searches, find the word behind each one, and add them with a match type that will not block real customers. Then set a reminder to come back.
