Security companies run Google Ads across a wider range of buyers than most industries realize: homeowners wanting an alarm system, businesses needing guards or access control, and property managers needing surveillance across multiple sites. Running one generic “security services” campaign for all three wastes budget on clicks that were never a fit.
I have managed accounts for both residential alarm companies and commercial guard services, and the pattern that works is always the same: split by buyer type first, then by specific service, since a homeowner comparing alarm monitoring plans and a facilities manager sourcing a guard contract are searching, and buying, in completely different ways.
Why Residential and Commercial Security Need Separate Campaigns
A residential buyer usually wants a fast quote and self-service signup. A commercial buyer, especially for guard services or enterprise access control, is often going through a procurement process with multiple stakeholders and a longer timeline. The messaging, landing pages, and even the phone script for handling the lead need to differ.
The split that consistently performs better:
- Residential alarm and monitoring campaigns, optimized for fast quotes and self-signup
- Commercial guard services campaigns, targeting facilities and operations managers with a procurement-style landing page
- Access control and surveillance campaigns, which often target a technical or IT buyer rather than a facilities buyer
- Event and temporary security campaigns, a distinct urgent-need segment with its own keyword set
Keyword Strategy for Security Services
Broad terms like “security company” or “security services” pull in a mix of every buyer type plus a fair amount of job seekers looking for security guard positions. The keywords that actually convert are tied to a specific service and buyer:
- “home security system [city]” or “alarm monitoring [city]” for residential buyers
- “security guard company for [industry]” for commercial buyers with a specific vertical need
- “access control system installation [city]” for a more technical B2B buyer
- “event security company [city]” for time-sensitive, high-urgency bookings
Negative keywords should include “jobs,” “security guard training,” “how to become a security guard,” and “careers,” since these show up constantly in search terms reports for this industry and rarely produce a real customer.
Writing Ad Copy That Builds Trust Fast
Security is a trust-driven purchase, whether it is a homeowner or a facilities manager making the decision. Ad copy needs to reduce perceived risk before the click, not just describe the service:
- Licensing and certification stated directly, since security services are regulated and buyers actively look for this
- Response time guarantees where they apply, since speed matters more in this category than almost any other
- Years in business or number of sites protected, as a credibility signal
- A clear, low-friction next step, such as a free security assessment rather than a hard sales pitch
Landing Pages That Convert Security Leads
Residential and commercial landing pages should look genuinely different, not just reuse the same page with a different headline. A homeowner wants pricing and a simple signup. A commercial buyer wants proof of scale, compliance, and account management.
What a high-converting security landing page needs:
- Clear service area and response time commitments
- Licensing, certification, and insurance information visible without scrolling
- Case studies or client logos relevant to the specific buyer segment (residential testimonials versus commercial client logos)
- A low-friction next step matched to the buyer type: instant quote for residential, consultation request for commercial
Google Ads Benchmarks for Security Services
According to WordStream’s 2026 Google Ads Benchmarks report, based on more than 13,000 campaigns across 23 industries, the account-wide average cost per click is $5.42, with an average conversion rate of 8.18% and an average cost per lead of $66.69. Security services often sit near or above these averages given the trust-driven, higher-value nature of the purchase, especially on the commercial side.
| Metric | Account-wide 2026 benchmark | What it means for security campaigns |
|---|---|---|
| Average CPC | $5.42 | Residential keywords typically run below this, commercial and B2B security keywords often run above it |
| Average conversion rate | 8.18% | Your benchmark once residential and commercial campaigns are split and optimized separately |
| Average cost per lead | $66.69 | Useful comparison point, especially for residential monitoring leads where deal size is more predictable |
Tracking Leads Through Long Commercial Sales Cycles
Residential leads often convert quickly, but commercial security contracts can take weeks or months to close through a procurement process. If Google Ads only sees the initial form fill, it cannot distinguish a residential lead that closed in two days from a commercial lead that closed three months later at ten times the contract value.
Feeding closed-deal value back into Google Ads as an offline conversion, split by residential and commercial, lets Smart Bidding properly value the keywords driving your highest-value commercial contracts instead of treating every lead the same.
