Negative Keywords for Service Businesses: A Starter List

Negative keywords tell Google which searches you don't want your ads to show for. They're one of the most powerful tools for protecting your Google Ads budget, and one of the most neglected. A service business with no negative keyword list is almost certainly paying for clicks that will never become customers.

Below is a starter list organized by category, plus the one rule that keeps a negative list from doing more harm than good.

The Service Business Negative Keyword Starter List

These are the categories that drain service business budgets. Adapt them to your business before applying.

Job seekers (people looking for employment, not your service):

• jobs, careers, hiring, salary, employment, job openings, apply, resume, how to become a

DIY and how-to (people who want to do it themselves):

• how to, DIY, do it yourself, yourself, tutorial, guide, instructions, how do I

Free and cheap (people who won't pay your rates):

• free, cheap, cheapest, low cost, budget, discount, coupon, bargain, for free

Education and research (people studying, not buying):

• course, courses, training, certification, class, classes, school, degree, definition, meaning, what is, wikipedia

Used, rental, and resale (wrong purchase intent):

• used, rental, rent, second hand, refurbished, resale, for sale (depending on your service)

Other businesses and B2B (if you serve consumers):

• wholesale, supplier, manufacturer, distributor, white label, franchise

Complaints and reputation (people researching problems):

• complaints, scam, lawsuit, reviews, ripoff, is X legit, reddit, bad reviews

Add to these your own list of services you don't offer and locations you don't serve. If you're a residential-only mover, "commercial" and "office" are negatives. If you serve one metro, every neighboring city you don't cover is a negative.

The One Rule That Matters

A negative keyword list is never copy-paste-and-forget. The single biggest mistake is blocking searches that would have become customers.

Before you add any negative keyword, ask one question: could this term stop someone who actually wants to hire me?

"Reviews" is a good example. It feels like a research term, but "best movers reviews [city]" is often a high-intent buyer doing final due diligence before hiring. Block it carelessly and you've cut off ready customers. The same goes for "cost" and "price," which sound like bargain-hunting but are frequently used by serious buyers comparing quotes.

The rule is simple: block bad searches, not good ones. When a term is ambiguous, don't add it account-wide on a hunch. Check your search term report to see whether it's actually wasting money before you exclude it.

How to Use Negative Keywords Properly

A few practices separate a clean account from a leaky one.

Build from your search term report, not just lists like this one:

‍This starter list is a head start, not a finished product. Your real negatives come from reviewing the actual searches triggering your ads. The search term report shows you exactly what people typed, and that's where the highest-value negatives come from.

Use negative keyword lists for terms that span campaigns:

‍Google lets you build shared negative lists and apply them across campaigns. Put your universal negatives (jobs, free, DIY) in a shared list so you maintain them in one place.

Mind your match types:

‍Negative keywords have match types too. A negative broad match on "free" blocks any search containing "free." A negative phrase or exact match is more surgical. For most universal junk terms, negative phrase match is the safe default.

Review monthly:

‍New junk searches appear constantly. A negative list built once and forgotten slowly stops protecting you. Pull the search term report at least monthly, add new negatives, and occasionally check that you haven't blocked something valuable.

Done consistently, this is one of the highest-ROI habits in a Google Ads account. We've seen a thorough negative keyword pass drop cost per qualified lead substantially on accounts that had been quietly wasting budget for months.

Frequently Asked Questions

What are negative keywords in Google Ads?

Negative keywords are terms you tell Google you don't want your ads to show for. They prevent your ads from appearing on irrelevant searches, which protects your budget and improves the quality of the traffic you pay for.

What negative keywords should every service business use?

Common universal negatives include job-seeker terms (jobs, careers, salary), DIY terms (how to, DIY, yourself), free and cheap terms (free, cheap, discount), and education terms (course, training, what is). You should also add services you don't offer and locations you don't serve.

Can negative keywords hurt my campaigns?

Yes, if you block searches that would have converted. Terms like "reviews," "cost," and "price" can look like research but are often used by ready-to-buy customers. Always ask whether a negative could block a real prospect before adding it, and lean on your search term report rather than guessing.

How many negative keywords should I have?

There's no magic number. Well-managed service business accounts often have a few hundred negatives built up over time from search term reviews. Quality and relevance matter far more than quantity.

How often should I update my negative keywords?

At least monthly. New irrelevant searches appear constantly, so reviewing your search term report regularly and adding new negatives keeps your account efficient over time.
