997 Negative Keywords for Google Ads Sorted by Industry (Import-Ready Lists)

Marketer analyzing ad dashboard data at desk — negative keywords for google ads

Every dollar your Google Ads budget spends on an irrelevant click is a dollar that could have reached a genuine prospect.

Across the accounts we manage, adding a structured negative keyword list on day one typically reduces wasted spend by 15% to 30% in the first month alone.

That’s not a rounding error. On a $10,000 monthly budget, that’s $1,500 to $3,000 redirected toward clicks that actually convert.

Below, you’ll find 997 negative keywords organised into a universal list and 12 industry-specific lists — each formatted for direct import into Google Ads.

Copy the keywords, paste them into your shared negative keyword list, and start filtering out junk traffic immediately.

Before we get to the lists, a quick primer on how to use them effectively — because a negative keyword applied incorrectly can block the very traffic you want.

How Negative Keywords Work (The 90-Second Version)

Marketer explaining ad filtering on whiteboard — negative keywords for google ads

Negative keywords tell Google: ‘Do not show my ad when a search query contains this word or phrase.’

They come in three match types, and the match type matters enormously.

Negative Broad Match

This is the default. Adding free as a negative broad match blocks your ad from showing whenever the word ‘free’ appears anywhere in the query, in any order.

The query ‘free plumbing quote’ would be blocked. So would ‘is this quote free.’

It does not block close variants, synonyms, or misspellings the way positive broad match expands them. Negative broad match is literal.

Insight

Unlike positive broad match, negative broad match won’t catch misspellings or synonyms. If you negate “free,” someone searching “fre plumbing quote” (a typo) could still trigger your ad. Add common misspellings of your most costly negatives separately.

Negative Phrase Match

Adding “free quote” (in quotes) blocks queries that contain the exact phrase ‘free quote’ in that order.

‘Get a free quote’ would be blocked. ‘Free plumbing quote’ would not, because ‘plumbing’ breaks the phrase.

Negative Exact Match

Adding [free quote] (in brackets) blocks only the exact query ‘free quote.’ Nothing more, nothing less.

Our recommendation for these lists. We recommend adding most keywords as negative broad match (no punctuation, just the word), or negative phrase match (just “the words” if it’s more than one word).

This gives you the widest protection.

We’ll flag specific cases where phrase or exact match is smarter.

How to Import These Lists Into Google Ads

  1. In your Google Ads account, navigate to Tools & Settings > Shared Library > Negative Keyword Lists.
  2. Click the blue + button to create a new list. Name it clearly (e.g., ‘Universal Negatives’ or ‘Dental Industry Negatives’).
  3. Click Add negative keywords, paste the relevant keywords from below (one per line), and save.
  4. Apply the list to the appropriate campaigns.

You can also add negative keywords at the campaign or ad group level.

Shared lists are more efficient for broad exclusions; ad group negatives are better for sculpting traffic between ad groups within a campaign.

Pro Tip

Name your shared lists with a clear prefix system like “NEG_Universal,” “NEG_Legal,” or “NEG_Campaign_Implants.” When you’re managing dozens of lists across multiple campaigns, consistent naming saves hours of troubleshooting.

A Word on Using These Lists Responsibly

These lists are starting points, not set-and-forget solutions.

Before importing, scan each list and remove any keyword that conflicts with your actual offering. If you’re a law firm that genuinely offers free consultations, don’t negate ‘free.’ If you’re a training provider, don’t negate ‘course’ or ‘class.’

Context is everything.

After importing, check your Search Terms report weekly for the first month, then fortnightly. You’ll find new negatives to add and occasionally discover that a keyword you negated is blocking good traffic.

Keep In Mind

Blindly importing a full list without reviewing it against your own services is one of the fastest ways to tank a campaign. Spend 10 minutes scanning before you paste — it could save you thousands in lost leads.

Now, let’s get into the lists.

Universal Negative Keywords (Apply to Almost Every Account)

These 152 keywords filter out searches related to jobs, education, DIY, free-seekers, and other intent signals that waste budget for most advertisers.

Unless your business specifically targets one of these intents, add the entire list.

By the Numbers

Queries containing “free,” “cheap,” or “DIY” account for a disproportionate share of wasted ad spend. In one audit of a $15K/month account, these three intent categories alone were responsible for 22% of total clicks with a 0% conversion rate.

Industry-Specific Negative Keyword Lists

Each list below is designed for the named industry.

Combine it with the universal list above for maximum coverage.

Pro Tip

Even if your industry isn’t listed here, scan the other lists for crossover terms. A financial planner might find useful negatives in the Education list, and a SaaS company might benefit from terms in the E-commerce list.

Keep In Mind

Terms like “do i need a lawyer” and “can i sue” might seem like prospect queries, but they overwhelmingly attract informational browsers — not people ready to hire. If your firm’s data shows otherwise, remove them from the list.

Insight

DIY queries are the single biggest budget drain for home service advertisers. Someone searching “how to unclog a drain” wants a YouTube video, not a $200 callout fee. The “how to” prefix alone can account for 10-15% of irrelevant clicks in a typical trades campaign.

3. Dental and Orthodontic (82 keywords)

Quick Win

If you run a dental practice, add “dental tourism” and its variants immediately. These searchers are specifically looking to travel overseas for cheaper treatment — they’ll never book with a local provider.

Real estate total: 88 keywords

Keep In Mind

Terms like “fsbo,” “sell without agent,” and “discount broker” represent people actively trying to avoid your service. These aren’t just irrelevant — they’re anti-intent. Every click from these queries is money spent on someone who’s already decided they don’t want you.

Insight

“Symptoms of” and “what causes” queries are research-stage searches that rarely convert to appointments. However, if you run content marketing alongside paid ads, consider targeting these organically instead — they build trust with patients who may book later.

Pro Tip

Calculator queries (“mortgage calculator,” “tax calculator”) have massive search volume but near-zero conversion intent for service providers. These searchers want a free tool, not a consultation. Negate them in your paid campaigns and consider building a free calculator on your site to capture this traffic organically instead.

Keep In Mind

Be careful with “review” and “reviews” as negatives. For some e-commerce brands, “[brand name] review” queries convert at high rates because the searcher is in the final decision stage. Consider using negative phrase match for “product review site” or “review blog” instead of a blanket broad match negative on “review.”

Important note: If you sell SaaS, review this list carefully. Terms like ‘demo,’ ‘integration,’ ‘api,’ or ‘pricing’ might be relevant to your product. Remove any that align with your actual buyer’s search behaviour.

Quick Win

Add “cracked,” “pirated,” and “nulled” immediately — no exceptions. These searchers are actively trying to steal software. There is zero scenario where these clicks convert into paying customers.

Insight

Platform names like “Coursera,” “Udemy,” and “Skillshare” are critical negatives for paid training providers. Searchers including these terms are looking for low-cost or free alternatives on those specific platforms — not your premium offering.

Pro Tip

If you run a gym or fitness studio, “home workout” and “no gym” queries are your direct competitors — but they’re not paying customers. These searchers have already decided against a gym membership. Save your budget for people searching with local intent.

By the Numbers

Recipe-related queries outnumber restaurant booking queries by roughly 50 to 1 in Google’s search volume data. Without “recipe” and “how to cook” as negatives, a restaurant’s ad budget can be consumed almost entirely by home cooks who will never walk through the door.

If you’re a mechanic or detailer, add “car for sale,” “buy used car,” and “sell my car” right away. These are high-volume queries that look automotive-related but have completely different intent from someone needing a service or repair.

How to Build on These Lists Over Time

Marketer organizing tiered keyword strategy in notebook — negative keywords for google ads
Marketer organizing tiered keyword strategy in notebook — negative keywords for google ads

Importing these lists is step one. The real value compounds when you treat negative keyword management as an ongoing discipline.

Mine Your Search Terms Report Weekly

Your Search Terms report (found under Insights & Reports > Search Terms in Google Ads) shows the actual queries triggering your ads.

Sort by cost or impressions and scan for irrelevant terms. Add new negatives directly from this report.

In the first 30 days of a new campaign, we check this daily.

Use Tiered Negative Keyword Lists

We structure negative keyword lists in three tiers:

Tier 1: Account-level universals. The universal list above. Applied to every campaign in the account via a shared list.

Tier 2: Industry-specific. The relevant industry list from above. Applied to all campaigns via a shared list.

Tier 3: Campaign-specific. Negatives that only apply to certain campaigns. For example, a dentist running separate campaigns for ‘implants’ and ‘orthodontics’ might negate ‘braces’ in the implants campaign and ‘implant’ in the orthodontics campaign to prevent overlap.

This tiered approach keeps your lists organised and prevents the common problem of one massive, unmanageable list where you can’t remember why a keyword was added.

Pro Tip

Add a note or label to each negative keyword list with the date it was created and the reason. Six months from now, you (or a new team member) will thank yourself when trying to understand why “training” is negated in one campaign but not another.

Watch for False Negatives

A ‘false negative’ is when you accidentally block a keyword that real prospects actually search. Common culprits:

  • Negating ‘free’ when you offer free consultations or free quotes.
  • Negating ‘used’ when you sell certified pre-owned vehicles.
  • Negating ‘cheap’ when your audience genuinely searches ‘cheap flights’ or ‘cheap insurance’ with purchase intent.
  • Negating ‘review’ when prospects search ‘your brand review’ before converting.

If you notice a sudden drop in impressions or conversions after adding negatives, check your negative keyword lists first.

It’s one of the most common causes of unexplained performance drops.

Use Negative Keyword Conflicts Tool

Google Ads flags conflicts when a negative keyword blocks a positive keyword in the same ad group or campaign.

Check for these regularly under Recommendations or by running the keyword diagnostics. A conflict means your ad literally cannot show for a keyword you’re bidding on.

Consider Match Type Carefully for Ambiguous Terms

Some words are negative in one context and positive in another.

The word ‘training’ is a negative for a dog groomer but a positive for a dog trainer. For ambiguous terms, use negative phrase match or negative exact match instead of broad match to limit the blocking scope.

For example, a personal injury law firm might add “how to file” as a negative phrase match (blocking DIY filers) but would not add file as a negative broad match (which would block ‘file a claim with [firm name]’).

Keep In Mind

A single overly broad negative keyword can silently suppress thousands of impressions per month. If you’re ever unsure about a term, start with negative exact match or phrase match — you can always broaden it later, but you can’t recover lost impressions from an overzealous broad match negative.

Common Mistakes That Waste the Effort

Team troubleshooting campaign errors on screen — negative keywords for google ads

Adding Negatives and Never Reviewing Them

Markets change. Your offerings change.

A keyword you negated six months ago might now be relevant. Audit your negative keyword lists quarterly. Remove anything that no longer applies.

Duplicating Negatives Across Levels

If a keyword is in a shared list applied to all campaigns, don’t also add it at the campaign level.

It creates clutter and makes troubleshooting harder. Pick one level and stick to it.

Negating Single Letters or Ultra-Short Words

Adding single-character negatives or very common two-letter words can have unpredictable effects.

Be specific. Instead of negating ‘a’, negate the full phrase you want to block.

Ignoring Display and Performance Max

Negative keywords work differently (or not at all) across campaign types.

In Search campaigns, they work precisely.

In Performance Max campaigns, account-level negative keywords can be added through your Google Ads representative or via brand exclusion lists, but the control is more limited.

In Display campaigns, negatives function as topic or context signals rather than exact query blocks. Adjust your expectations by campaign type.

Insight

Performance Max campaigns now allow account-level negatives without contacting a Google rep — but only through the account-level settings, not at the campaign level. Check your Google Ads interface under Account Settings > Negative Keywords for the latest options, as Google updates this functionality frequently.

  1. Copy the universal list and create a shared negative keyword list in your Google Ads account. Apply it to all Search campaigns.
  2. Copy the industry list most relevant to your business. Review it for conflicts with your actual offerings, remove any that don’t apply, and create a second shared list.
  3. Check your Search Terms report right now. Sort by cost descending. You’ll almost certainly find irrelevant queries you’re paying for today.
  4. Set a calendar reminder to review search terms weekly for the next month, then fortnightly after that.
  5. Build your Tier 3 list over time with campaign-specific negatives unique to your account.

Negative keyword management isn’t glamorous. It won’t make a case study or a conference talk.

But across every account we manage, it’s one of the highest-ROI activities you can perform in Google Ads.

These 997 keywords are your starting point. Your Search Terms report will write the rest.
