Negative keywords in Google Ads: cut wasted spend and reach only buyers

The problemWhat negative keywords are

A normal keyword tells Google when to show your ad. A negative keyword does the opposite: it tells Google when to hold your ad back. If you sell premium leather boots and you add 'free' as a negative, your ad will not appear for searches like 'free boots'.

They do not cost anything to add and they never trigger an ad themselves. Their only job is to filter out searches that waste your money or attract the wrong audience.

The approachHow they save budget

Most Google Ads waste comes from clicks that were never going to convert. Someone searching for a job at your company, a free version of your product, or a do-it-yourself tutorial can still click a poorly filtered ad. You pay for that click and get nothing back.

Negative keywords cut those clicks before they happen. The money you save goes back into searches with real buying intent, which lifts your conversion rate and lowers your cost per result without raising your budget.

• Fewer wasted clicks means a lower cost per conversion.
• Cleaner traffic gives Smart Bidding better signals to learn from.
• Higher relevance can improve Quality Score and lower your cost per click.

In practiceNegative match types

Negatives have their own match types, and they behave differently from positive keywords. The biggest difference: negatives never match close variants, so plurals, misspellings and synonyms are not blocked automatically. You have to add them yourself.

• Negative broad: blocks searches that contain all your words in any order. 'running shoes' as a broad negative blocks 'cheap running shoes' but not 'shoes for running'.
• Negative phrase: blocks searches that contain your words in the exact order. 'free shipping' blocks 'order with free shipping' but not 'shipping is free'.
• Negative exact: blocks only the precise search, nothing more. 'free' as an exact negative blocks the single word 'free' but not 'free trial'.

What you getWhere to add negatives

You can apply negatives at three levels, and choosing the right one keeps your account clean. Account-wide brand safety terms belong in a shared list, while a negative that only makes sense for one product belongs in its ad group.

• Campaign level: blocks the term across every ad group in that campaign. Good for broad exclusions like 'jobs' or 'free'.
• Ad group level: blocks the term in one ad group only. Useful for steering traffic between ad groups in the same campaign.
• Shared list: a reusable set you can attach to many campaigns at once, so you maintain it in one place.

QualityFind negatives with the search terms report

The search terms report shows the actual queries that triggered your ads, not just the keywords you bid on. This is the single best source of new negatives, because it tells you exactly where your money went.

Sort by cost or by clicks, then scan for searches that have nothing to do with your offer. Add the irrelevant ones as negatives in the right match type, and over a few weeks your traffic gets noticeably cleaner.

• Open Campaigns, then Search terms, and set a recent date range.
• Look for queries with spend but no conversions.
• Add clear mismatches as exact or phrase negatives so you stay precise.

OverviewA starter list of common negatives

Before your first search terms report exists, a starter list catches the most common money wasters. Adjust it to your business, because a word like 'free' is poison for a paid product but essential if you actually offer a free tier.

• Price seekers: 'free', 'cheap', 'discount', 'coupon' when you are not the budget option.
• Job hunters: 'jobs', 'career', 'salary', 'vacancy', 'hiring'.
• Self-service intent: 'diy', 'how to', 'tutorial', 'template' for done-for-you services.
• Research only: 'meaning', 'definition', 'wikipedia', 'examples'.

How it worksOngoing maintenance

A negative keyword list is never finished. Search behaviour shifts, new products launch, and broad and phrase keywords keep pulling in fresh queries you did not anticipate. A short weekly review keeps waste from creeping back in.

Be careful not to over-block. An aggressive broad negative can quietly suppress good traffic, so when results drop unexpectedly, check whether a recent negative is the cause before assuming the market changed.

• Review the search terms report weekly, or every few days while spend is high.
• Keep a shared list so a new exclusion protects every campaign at once.
• Audit your negatives quarterly to remove ones that now block valid searches.

The trade-offHow AdBuilder handles negatives

When AdBuilder builds your Search campaign from your website, it generates negative keywords as part of the structure, not as an afterthought. It reads what you actually sell, then proposes negatives that match your offer: price terms when you are premium, job and research terms that rarely convert, and exclusions that stop your Generic and Specific campaigns from competing for the same searches.

You review every negative before anything goes live, edit the ones you disagree with, and then push the whole campaign, keywords and negatives included, straight to your Google Ads account. There is no spreadsheet and no import step. Building and previewing your campaign is free; paid plans (Solo, Basic, Pro and Agency) add publishing plus ongoing optimization and insights. AI is included on every plan.

• Negatives are generated from your real products and services.
• They are placed at the right level to keep campaigns from overlapping.
• You stay in control: review and edit before you publish.

PricingOngoing negatives with Optimize

Negative-keyword work does not stop at launch, and neither does AdBuilder. After your campaign is live, the Optimize feature reads your real search-term data and automatically surfaces the queries that are wasting spend, then recommends exactly which terms to exclude. You apply a negative with one click straight in Google Ads, and every change is reversible if you change your mind.

It does more than negatives. Optimize also flags budgets to adjust, non-converting campaigns to pause, missing extensions and broken links, so the weekly maintenance this guide describes becomes a short list of one-click fixes instead of a manual report dig.

• Wasted search terms are surfaced automatically from live data.
• Exclude them as negatives with one click in Google Ads, and reverse any change.
• The same flow handles budgets, pausing weak campaigns, extensions and broken links.

In shortSee where your money goes with Insight

Insight is a performance dashboard that shows your account by segment, including your top search terms, so you can spot which queries deserve a negative before they drain the budget. Alongside the charts you get a written AI analysis of what is happening, and a chatbot you can ask about your account in plain language.

Together with Optimize, this turns the never-finished maintenance loop into something you actually keep up with: the data points to the wasted searches, and excluding them is one click away.

• Segmented performance, including a top search terms view.
• A written AI analysis that explains what is driving your results.
• A chatbot that answers questions about your account.
