Google Ads Keywords for Service Businesses: What to Bid On and 100+ Negative Keywords to Block
Most wasted spend in service-business Google Ads accounts comes from a handful of search patterns: DIY, jobs, parts and research searches. Here's how to pick the right keywords and block the wrong ones.
The best Google Ads keywords for a service business combine a specific service with a hiring signal, such as "near me", "emergency", "company", "cost" or a location, and are run as phrase or exact match. Just as important is the negative keyword list: blocking DIY, job-seeker, parts-shopping and freebie searches removes a large share of wasted spend in most service accounts.
Key takeaways
- Bid on service + hiring signal keywords, not the bare service name.
- Use phrase and exact match; test broad match only once conversion tracking is reliable.
- Build negative keyword lists before launch and apply them to every campaign.
- The search terms report is where your real negative keywords come from. Check it weekly.
- Group keywords by service and value, so high-value jobs get their own budget.
The keyword formula that works
[service] + [hiring signal]
| Hiring signal | Examples |
|---|---|
| Location | "plumber near me", "electrician in [area]" |
| Urgency | "emergency plumber", "24 hour locksmith", "same day AC repair" |
| Business type | "roofing company", "HVAC contractor", "cleaning service" |
| Price | "furnace replacement cost", "how much to rewire a house" |
| Specific job | "water heater installation", "sewer line repair", "roof leak repair" |
The bare service name ("plumbing") is often too broad: it pulls in research, jobs and DIY searches.
Match types for service businesses
| Match type | What it does | When to use it |
|---|---|---|
Exact [emergency plumber] |
Same meaning as the keyword | Your highest-value, proven searches |
Phrase "water heater installation" |
Includes the meaning, with words around it | Core of most service accounts |
Broad furnace repair |
Related searches, as judged by Google | Only with reliable conversion data, tested separately |

Wrong service
Services you don't offer. A drain company that doesn't do gas work should add gas, gas line, boiler (if not offered) and similar.
Competitors (optional)
Competitor brand names, if you don't want to bid on them. Many businesses choose not to.

Professional services follow the same pattern with different terms. See Google Ads for law firms and Google Ads for dentists for their negative keyword lists.
The weekly search terms routine
- Open Insights and reports → Search terms for the last 7 days
- Sort by cost
- For every irrelevant search: add a negative (to the shared list if it's a theme)
- For every converting search not already a keyword: add it as phrase or exact match
- Note new themes, such as a new competitor or new DIY phrasing
Fifteen minutes a week here usually saves more money than any other optimisation.
Grouping keywords by value
Put services with very different job values in separate campaigns:
- Emergency / high urgency: highest bids, call-focused, schedule matched to when you answer
- High-value installs: higher bids, longer decision; form leads are fine
- Small repairs / maintenance: lower bids, or exclude if the margin doesn't support paid leads
This lets you control budget by what each job is worth. The full structure is in our Google Ads playbook for service businesses.
Frequently asked questions
What are the best Google Ads keywords for a service business?
Keywords that combine a specific service with a hiring signal, such as a location, urgency, business type, price or a specific job, run as phrase or exact match. For example "emergency plumber", "roof repair near me" or "furnace replacement cost".
What negative keywords should a service business use?
Block DIY and research terms ("how to", "diy", "youtube"), job-seeker terms ("jobs", "salary", "apprenticeship"), parts and shopping terms ("parts", "home depot", "wholesale"), "free", and services or customer types you don't serve.
Should I use broad match for a service business?
Usually not at first. Broad match relies on good conversion data to target well. Start with phrase and exact match, and test broad match separately once your tracking reliably counts real leads.
How often should I add negative keywords?
Check the search terms report weekly, and add negatives for every irrelevant search theme. New accounts need this most in the first few weeks.
Should I bid on "near me" keywords?
Usually yes. "Near me" searches signal local hiring intent. Make sure location targeting is set to people in your service area, so ads only show to people you can actually serve.
