A property manager planning a new warehouse types "general contractor" into Google. A dentist planning a second office types "commercial general contractor." The two searches differ by one word, and Google answers them with different lists of builders.
That one word matters to anyone paying for clicks. Your keywords decide which of those two searches your ads answer, and so which of those two people you pay for.
This chapter shows what one word did to Google's results in an example market, what exact match does and doesn't promise, and how a new account starts on the short list of searches that name commercial work. It follows Chapter 5, which built that list.
Google Showed 3 Commercial Builders for "General Contractor Cincinnati." Putting "Commercial" in Front Made It 10.
The results Google shows for a search are a good read on what Google thinks the person wants. So we ran 30 searches in our example market, Cincinnati, on October 30, 2026, and classified every business in the organic results and the map listings: commercial builders, residential firms (remodelers and home builders), directories and everything else. A Google map link counted as nothing; only businesses were counted.
"General contractor cincinnati" returned 12 businesses. Three were commercial builders and two were residential firms. "Commercial general contractor cincinnati" also returned 12, and 10 of them were commercial builders, with no residential firms at all.
The same thing held across the whole set:
- The 24 searches that named commercial work (commercial, office, warehouse, tenant, medical, retail and the like) returned 266 businesses. 56% were commercial builders. 1% were residential firms.
- The 6 searches that didn't returned 72. 29% were commercial builders. 28% were residential firms.
A second pair told the same story. "General contractor near me" returned 4 commercial builders and 3 residential firms among 12 businesses. "Commercial contractor near me" returned 8 commercial builders and no residential firms.
Industry terms didn't help the way builders might expect. "Design build contractor cincinnati" returned 12 businesses, and 7 were residential firms. Homeowners hire design-build remodelers too, and Google knows it.
These are organic and map results, not ads, and one market on one day. But they show the point plainly: a search without a commercial word is partly a homeowner's search. An ad bought on it reaches some of those homeowners.
Exact Match Means "Same Meaning" to Google, and Google Decides Which Words Are Implied
Every keyword in Google Ads carries a match type, which sets how closely a search has to resemble the keyword before your ad can enter the auction for it. There are three:
- Broad match is what every new keyword gets unless you change it. A broad keyword for commercial general contractor can put a builder's ad on any search Google decides is related to it, a much wider net than the keyword's own words.
- Phrase match goes in quotation marks. "Office build out" in phrase match can show on "office build out cost cincinnati," because the search carries the keyword's meaning with extra words around it.
- Exact match goes in square brackets. Google's help page describes it as matching searches whose meaning or intent is the same as the keyword's. It's the setting that gives a builder the tightest control over which searches the ad enters, and it reaches the fewest of them.
The word that matters there is "meaning." Exact match no longer means the search must be typed character for character. Google applies what it calls close variants to every match type, and there's no setting to turn them off. Google's close variant page lists what an exact match keyword can still pick up. For a builder, that means a search for "contractor commercial general" (words reordered), "commercial general contractors" (a plural), "general contractor for commercial" (a small word added) or a synonym of the keyword. It also means searches with the same intent, and searches where Google thinks a word is implied.
That last one is the catch for a builder. Google's own example is a keyword for a "daydream vr headset" showing on a search for "daydream headset." Google decided "vr" went without saying. Nothing in Google's help pages says how it would treat "commercial" in a keyword like [commercial general contractor]. The results above suggest Google reads the word as changing the meaning, since it changes the builders Google shows. But Google makes that call, not you.
So exact match is the tightest setting available, and it still needs checking. The search terms report, covered below, is the check.
Eighteen Commercial Construction Keywords Get About 370 Searches a Month in One City. A List That Short Belongs in Exact Match.
Chapter 5 counted 18 clearly commercial searches in the example market's keyword ideas, with about 370 searches a month between them in the Cincinnati metro: "commercial general contractor," "commercial contractors," "commercial construction company," "pre engineered metal buildings," "design build firm," "tenant improvement contractor," "medical office construction," "data center construction" and others. Most drew 10 to 40 searches a month each.
Compare the searches Chapter 5 put on the watch list: four generic ones such as "general contractors near me" (about 720 a month) and "general contractor" (about 590) drew about 2,090 between them. Those are bigger, and per the results above, they're mixed with homeowners.
A new account starts with the short list. We call this first stage Isolation: every launch keyword in exact match, filed into the kind-of-work ad groups from Chapter 4, with each bid typed in by hand. Fourteen of the 18 name commercial work outright, which puts them close to the searches that turned up commercial builders above. The other four are design-build terms such as "design build firm," and the design-build search above turned up mostly residential firms. Keep those four, since owners do search them, but read their search terms most closely.
Two things about the list will feel wrong at first, and both are normal:
- The volumes look tiny. Ten or twenty searches a month per keyword is typical for commercial work in a single metro. One of those searches can be an owner with a 20,000-square-foot building to put up. Thin volume is the nature of the market, not a sign the keyword is a bad one.
- The generic searches are missing. "General contractor" stays off the launch list and goes on a watch list. It comes back later, under the conditions in the last section.
If your firm builds only certain kinds of buildings, cut the list to match. A builder who never does metal buildings drops those keywords; a builder known for medical offices adds the specific versions owners search, such as "dental office build out."
Exact Match Can Still Show a Builder's Ad on a Search Without "Commercial." The Search Terms Report Lists Each One.
Your keyword list says what you meant to buy. The search terms report shows what owners, homeowners and everyone else typed on the way to your ad. Those can differ, as section two explained, so a builder reads that report every week from launch.
Look for two kinds of search:
- Searches that dropped the commercial word. If [commercial general contractor] matched a search for "general contractor," Google treated "commercial" as implied. You can't change that judgment, but you can add the plain search as a negative keyword in that ad group, so your ad stops showing for it.
- Searches that added a homeowner's word. Home, house, kitchen, bathroom, basement, deck, remodel and addition all point to residential work. Add each one you see to the account's negative list. Chapter 5 started that list; this report keeps it growing.
The two kinds take different negatives. A whole plain search goes in as an exact match negative, written [general contractor]. Google's page on negative match types says an exact match negative blocks only that search, in that order, with no extra words, so each version that shows up gets its own line: "general contractor cincinnati" is a separate negative. Negatives also skip close variants. Google won't block the plural for you, so [general contractors] needs its own line too. A homeowner's word goes in as a broad match negative, written plainly as kitchen, which blocks any search that contains it.
A short exact match account makes the report quick to read. With a few dozen keywords and a few hundred searches a month in the market, a week's search terms fit on one screen. That's one of the quiet advantages of starting narrow: every search can be read by a person.
Broad Match Needs About 30 Conversions a Month Before It Can Tell a Building Owner From a Homeowner
Broad match has its place in a builder's account, just not at launch. We call the next stage Exploration: broad match keywords, with Google setting each bid toward a target cost per conversion. Broad match reaches the longer, odder searches no keyword list predicts. Google's bidding decides which of them are worth paying for, and it learns that from the conversions Chapter 1 set up.
The trigger is volume, not time. In our experience Exploration works once an account logs about 30 good conversions a month, meaning real project inquiries, not job applications or vendor emails. Busy accounts can get there in month two or three. A single-market commercial builder may take much longer, and Chapter 7 deals with that gap. Until then, broad match has too little to learn from, and the homeowners in those generic searches stay in the mix.
Keep the launch keywords when broad match arrives. When several of a builder's campaigns could answer one owner's search, Google settles it in a fixed order, and first in line is a bracketed keyword whose words mirror the owner's. So when an owner searches "commercial general contractor" word for word, and your account holds [commercial general contractor], that keyword gets priority over every broad and phrase keyword you run, and over Performance Max too. Priority only decides which of your campaigns enters the auction, not whether the ad wins it. It also needs the keyword to be eligible: Google drops the priority when the campaign is limited by budget or the keyword carries "low search volume" status. Thin commercial keywords are the ones to check for that status.
That's how the account grows: the known commercial searches first, in exact match, then broad match once there's enough conversion data to steer it. If you'd like help building that launch list for your firm, our Google Ads agency sets up commercial builders' accounts this way.
