Every few years someone announces that keywords are dead. Voice search was going to kill them. Then semantic search. Now AI answers. And every year the same thing happens in our clients' accounts: the contractors who did the boring work of identifying what people actually type, and building a page for each of those things, take the calls.
Keywords aren't dead. What died is keyword stuffing — the practice of jamming "Dallas plumber" into a page 40 times. What replaced it is something better for real businesses: Google now rewards the site that most completely covers a topic for a specific place. That's still a keyword strategy. It's just a smarter one.
Why keywords matter more for contractors than almost any other business
A homeowner with water coming through the ceiling doesn't browse. They don't scroll social media looking for inspiration. They pull out a phone and type five words. Whoever owns those five words in that ZIP code gets a call that turns into $400 — or $12,000.
That's the whole game. Home services is one of the last categories where demand is almost entirely reactive and searched. Nobody wakes up wanting a new water heater. Something breaks, they search, and they call one of the first three names they see. Your marketing job is not to create demand. It's to be standing where the demand already is.
The mistake almost every contractor makes
They chase volume. They see that "plumbing" gets 550,000 searches a month and decide that's the word to go after. Meanwhile "burst pipe repair" gets 1,300 searches — and converts at a multiple no head term can touch.
Here's the correct hierarchy for a service business:
- Intent first. Is this person buying or reading? "Emergency AC repair" is buying. "How does a heat pump work" is reading.
- Commercial value second. Use average CPC as your proxy. High CPC = high buyer value.
- Volume third. It only matters after the first two check out.
A term with 500 monthly searches at a $50 CPC will out-earn a term with 100,000 searches at $3 every single time. Volume feeds your ego. Intent feeds your schedule.
Your city is not the country
The second mistake is assuming national volume is your volume. It isn't. A market's share of national search demand roughly tracks its share of the U.S. population, so a 60,000-person suburb sees about 0.018% of a national number.
Take "plumber," at 550,000 national searches a month. In that suburb, that's roughly 95 searches. Contractors hear that and get discouraged. They shouldn't — here's the math that matters:
- 95 local searches × 30% click-through from the #1 organic position = ~29 visits
- 29 visits × 25% call rate = ~7 calls
- 7 calls × 70% booking rate × $450 average ticket = ~$2,200/month from one keyword in one town
Now do that for 40 services across 15 cities you serve. That's the actual model: hundreds of small wins, not one big one. It's also why the contractor with 200 well-built pages beats the one with a beautiful 8-page website every time.
The five keyword types every contractor site needs
- Emergency terms — "emergency plumber," "emergency AC repair," "24 hour electrician." Low volume, highest CPC, fastest cash.
- Service + city terms — "drain cleaning Tampa," "furnace replacement Naperville." 70–80% of your organic revenue lives here.
- Replacement and big-ticket terms — "AC replacement," "electrical panel upgrade," "repiping." Modest volume, five-figure tickets.
- Maintenance terms — "AC tune up," "plumbing maintenance." These build the recurring agreements that carry your slow season.
- Informational terms — "how much does a new HVAC system cost." These capture buyers 30–90 days out and are increasingly what AI assistants cite when a homeowner asks for advice.
What changed with AI search — and what didn't
AI Overviews and ChatGPT-style assistants have changed the format of the answer, not the source of it. These systems still pull from pages that clearly and specifically answer a question. If your site has a real page about tankless water heater installation in your city, with pricing guidance, FAQs and proper schema, you are a candidate to be the cited source. If you have one "Services" page listing 22 bullet points, you are not.
In other words: the work that wins in AI search is the same work that has always won in organic search. Cover the topic completely, page by page, city by city.
The three keyword lists we've published — with real data
We pulled fresh U.S. search volume, average cost-per-click and competition data straight from Google's advertising keyword database for all three trades we serve. That's 188 keywords, grouped by service category, with the intent signals you need to prioritize them:
Plumbing keywords
74 terms — drains and sewers, water heaters, leaks and repiping, fixtures, water treatment, gas lines and commercial work.
HVAC keywords
59 terms — AC and furnace repair, replacement and install, mini splits, tune-ups, ductwork and indoor air quality, plus the seasonality factor.
Electrical keywords
55 terms — panel upgrades and rewires, EV chargers, generators, lighting, outlets and safety work, plus the two fastest-growing categories.
How to actually use these lists this week
- Pick your 8–12 money services — the work you want more of and profit most from.
- Audit what you have. One deep page per money service, or one thin bullet on a services page? Be honest.
- Build the missing service pages — 900–1,500 words, real photos of your crews, pricing guidance, FAQs, schema.
- Add city pages for each service in each city you legitimately serve, with genuinely local content.
- Mirror the language in Google Business Profile — services, posts, photos, review requests.
- Track by keyword group, not by traffic. Emergency terms, replacement terms and maintenance terms should each be scored separately.
Get your keywords mapped to your city — free
A national keyword list is only half the answer. What actually drives calls is your service + your city. We built a free tool that combines every keyword in these lists with your service area and hands you the prioritized list of the terms that matter most in your market — for plumbing, HVAC, or electrical.
If you'd rather have a team do this for you — the research, the pages, the city coverage, the Google Business Profile work — that's exactly what we've done for plumbing, HVAC and electrical contractors since 2010.
