Google Search Ads for Fire Alarm Companies: What to Bid On and What to Block

An owner turns on Google Ads with one campaign and the keyword “fire alarm,” and by Monday the search terms read “smoke detector beeping,” “how to turn off fire alarm” and “fire alarm technician jobs.” Meanwhile the property manager who searched “fire alarm inspection” plus his city lands on the homepage and never calls.

Google Search ads work for a fire alarm company when they’re built to catch commercial buyers and block everyone else. Split campaigns by service, send each one to its own page, start with phrase and exact match, and load negative keywords before launch. Target people located in your area, count calls as conversions, and read the search terms every week. Every click should come from someone who could sign a service agreement.

Paid search is one piece of marketing for fire alarm companies, and why ads come after the pages are built covers the order. Local Services Ads are a separate product; this post covers Search ads.

Build one campaign per service, not one for “fire alarm”

Google’s advice on organizing ad groups is to “pick a narrow theme and create ad groups around that theme.” When settings need to differ, it says to “create a separate campaign.”

Buyers search by service, too. Ahrefs’ US monthly estimates put “fire alarm monitoring” at 3,900 searches, “fire alarm installation” at 3,700, “fire alarm inspection” at 1,900 and “fire alarm repair” at 450.

So, set up four campaigns: Inspection and Testing, Monitoring, Repair and Deficiencies, and New Installation. Keep ad groups tight, so “fire alarm inspection” and “fire alarm testing” sit in separate groups under Inspection.

Start with phrase and exact match

Google’s page on match types says broad match can show your ad on “searches that don’t contain the direct meaning of your keywords.” Exact match “reaches fewer searches than both phrase and broad match.”

Google also says “It’s critical to use Smart Bidding with broad match,” and Smart Bidding needs conversion data you won’t have on day one. Launch with phrase and exact match on buyer terms like “fire alarm inspection,” “fire alarm monitoring company,” “fire alarm deficiency repair” and “commercial fire alarm installation.” Even exact match now works on meaning, not only the literal words, so negatives still matter.

Load your negative keyword list before the first click

“Negative keywords let you exclude search terms from your campaigns,” according to Google’s negative keyword page. But “Negative keywords won’t match to close variants or other expansions,” so add singular and plural forms yourself.

The same keyword tool estimates “smoke detector beeping” at 11,000 US searches a month, “fire alarm sound” at 4,900, “how to turn off fire alarm” at 3,000 and “fire alarm technician jobs” at 600. Not one of those comes from a building owner. How many of those clicks are you paying for right now?

Build one shared negative keyword list called “Fire alarm: not buyers” and apply it to all four campaigns. A starter set:

• Jobs and training: jobs, careers, hiring, salary, apprentice, training, course, certification, NICET, exam
• Homeowners: beeping, chirping, going off, how to turn off, reset, fire alarm sound, ringtone
• Residential and shopping: home, house, apartment, DIY, battery, buy, Amazon, Home Depot, Lowe’s
• Other: free, PDF, wiring diagram, code book, meaning, test button

Don’t block “test” or “testing” on their own, since “fire alarm testing” is a buyer search. Use “test button” as a phrase negative instead, and drop “apartment” if you serve apartment buildings.

Read the search terms report every week

Google’s search terms report shows what people actually typed, though “Some search terms that don’t have enough query activity are omitted.” When did you last open yours?

For the first two months, sort the report by clicks every week and check the boxes next to anything a building owner would never type. Save them to your shared list, and watch for new patterns like your city fire department’s name or a monitoring brand’s customer login.

Every click should come from someone who could sign a service agreement. This report shows you the ones that didn’t.

Show ads to people in your service area

Google’s default location setting, “Presence or interest,” also reaches “people who have shown interest in your targeted locations.” “Presence” sticks to people “likely to be located, or regularly located” there.

Switch every campaign to Presence. You service buildings you can drive to.

Write ads that match the search and land on the matching page

A responsive search ad takes “up to 15 headlines and 4 descriptions,” and Google mixes them. Google warns that “pinning isn’t recommended for most advertisers and can affect ad strength.”

In the Inspection ad group, write headlines like “Fire Alarm Inspection and Testing,” “Annual Inspection Reports for Your AHJ” and “Deficiency Repairs Quoted in Writing.” Pin the service name to Headline 1 if every ad must say it, and leave the rest unpinned.

Then send the click to an inspection page built to answer the owner’s questions. Google’s landing page experience rating favors pages that “have text that relates to a person’s search terms.” If your page is weak, fix it first.

Count calls as conversions, then let Smart Bidding learn

Call assets put your number on the ad, and on phones “a clickable call button will be shown under your responsive search ad.” Turn on call reporting and Google creates a conversion action called “Calls from ads.” Add calls to the number on your website too, which swaps in a forwarding number for ad visitors.

Google’s call conversion page says “You set a minimum call length.” Set it long enough to skip hang-ups and wrong numbers. Schedule the ads for hours when someone can answer, since a click that rings a closed office is wasted. Who answers your phone after the office closes?

Smart Bidding needs “conversion tracking enabled,” and Google recommends periods with “at least 30 conversions, such as a month or longer.” Start with manual or simple bidding and switch to Maximize conversions once calls come in steadily. We set this up as part of our Google Ads service, and tracking the rest of your marketing is its own job.

Now, Google may push you toward AI Max or Performance Max. AI Max for Search, announced in May 2025, uses “broad match and keywordless technology,” and Performance Max got campaign-level negative keywords in early 2025. Both widen your reach, so the negative list matters more. Stay on standard Search until calls are tracked.

Do it yourself, or have us do it

Build four service campaigns, start on phrase and exact match, and apply a shared negative list before launch. Switch to Presence, point each campaign at its service page, track calls, and read the search terms weekly.

Or hand it off: request the audit below and we’ll show you where your ad clicks are really going.

Start with the search terms report

Open it for the last 30 days, sort by clicks, and count how many of the top 20 searches came from someone who owns or manages a commercial building. Add every one that didn’t to a shared negative list today, then switch location targeting to “Presence.” Every click should come from someone who could sign a service agreement. Then read the report again next week.

Common questions

Should a fire alarm company run Google Ads?

Yes, if the account is split by service, blocks homeowner and job searches, and tracks calls.

Which keyword match type should a new account start with?

Start with phrase and exact match. Google pairs broad match with Smart Bidding, which needs call tracking first.

Why do my ads get clicks from people with beeping smoke detectors?

Your keywords are matching homeowner searches. Add negatives like “beeping,” “chirping,” “battery” and “how to turn off,” and add each singular and plural form yourself.

Does AI Max ignore my negative keywords?

No. Google says negative keywords are still respected, but AI Max widens matching, so keep your list current.
