Google Ads for Radon Testing and Mitigation: Campaign Structure, Budget, and Lead Economics
Radon searches happen when someone already has a problem. A home inspector found elevated levels, a title company requires a test before closing, or a failed test blocks a sale. Campaign structure, keyword splits, and landing pages must match that urgency or you waste budget on the wrong traffic.
Testing and mitigation searches look similar but convert differently. Testing jobs close fast at lower ticket values. Mitigation jobs take longer and pay more. Most operators run both services, so your Google Ads account must separate the intent or your cost per lead will look worse than it is. Search campaigns for radon sit at the top of the page without Local Services Ads placements above them.
Why Google Ads Works for Radon Testing and Mitigation
Radon searches happen when someone needs an answer now. A home inspector flags elevated levels, a title company requires a test before closing, or a failed test demands mitigation within two weeks. Intent is high, decision windows are short.
Testing jobs run $350 to $600 and close fast. Mitigation work starts at $1,800 and can reach several thousand dollars. Testing jobs convert into mitigation work at rates that make the test profitable as a lead generation tool. The test is the entry point to the install.
Local Services Ads do not exist for radon. Your Search campaigns face less competition from Google-owned inventory than plumbing or HVAC categories where LSA placements push organic results below the fold. Your ads sit at the top.
Most homeowners cannot distinguish between testing and mitigation until they click. Campaign structure must separate the two or you waste budget on mismatched intent. Someone searching "radon test near me" wants a $400 inspection, not a $2,500 system quote.

Campaign Structure: Testing vs. Mitigation vs. Emergency
Testing campaigns target "radon test near me" and "radon inspection" with lower bids. Ad copy emphasizes same-day availability, certified technicians, and fast turnaround on lab results.
Mitigation campaigns target "radon mitigation cost", "radon system install", and "radon removal" with higher bids. The ticket is larger, so you can afford to pay more per lead. Ad copy leads with pricing transparency, post-mitigation guarantees, and certification badges.
Emergency campaigns target "failed radon test" and "high radon levels" with urgency-focused copy. These prospects face closing deadlines or health anxiety. Promises around 24-hour response, expedited installs, and compliance documentation convert at the highest rates.
Negative keyword lists must exclude "DIY", "kit", "detector", and "home depot". Self-service traffic never converts. Block "lawyer", "lawsuit", and "class action" to avoid legal-intent searches. Block "free" unless you offer free inspections as a legitimate lead magnet.
Keyword Strategy and Search Volume Reality
National search volume for radon-related terms runs in the tens of thousands per month. Serviceable local volume in a metro area is a fraction of that. You are fishing in a small pond.
Broad match on core terms like "radon mitigation" pulls in related long-tail queries: "radon mitigation contractors", "radon system cost", "how much does radon mitigation cost". Phrase match on "[city] radon test" prevents budget bleed into adjacent states.
Seasonal spikes occur in spring and fall when real estate activity peaks. Budget should flex higher in April, May, September, and October. Pause or reduce spend in December and January when transaction volume drops.
Competitor brand terms convert at higher rates than generic terms. Someone searching "[competitor name] radon" is already in-market and comparison shopping. Bid on these terms if your service area overlaps. Ad copy should highlight faster response times, better reviews, or lower prices without naming the competitor directly.
Lead Economics: Cost Per Lead, Close Rate, and Payback
Testing leads cost less than mitigation leads in most metros. Mitigation leads carry higher cost-per-lead but also higher ticket value. The economics work when you track both testing and mitigation revenue together.
Single-truck operators should manage daily spend carefully to avoid lead overflow. Multi-crew operations can scale spend higher if tracking confirms acceptable payback periods.
Conversion Tracking: Call Tracking, Form Fills, and Attribution
Call tracking with keyword-level attribution is mandatory. Most radon leads convert over the phone, not through forms. Without tracking, you cannot see which keywords drove the call or whether the lead booked an appointment.
Dynamic number insertion on landing pages ties each inbound call back to the keyword and ad that triggered it. You discover which terms drive call volume and which close at higher rates. Budget shifts accordingly.
Form submissions should trigger email and SMS confirmation within 60 seconds with next-available appointment slots. Speed-to-contact determines close rate. A prospect who waits hours for a callback books with the competitor who responded immediately.
CRM integration or manual lead tagging must separate testing inquiries from mitigation inquiries. If you pay per lead and a portion are testing-only inquiries that do not convert to mitigation, your effective cost per mitigation lead is higher than the nominal cost per lead. Track both.
Landing Pages: Trust Signals, Pricing, and Scheduling
Certification badges must appear above the fold. NRPP, AARST, state licenses. Radon work is health-driven and trust-gated. A homeowner researching mitigation reads about lung cancer risk and wants proof you know what you are doing.
Pricing transparency pre-qualifies leads. Testing at $350 to $600, mitigation starting at $1,800. Someone with a $500 budget for mitigation self-selects out before calling. Someone with a $3,000 budget calls immediately.
Before-and-after photos of installed systems answer the "will this actually work" objection. Show the fan, the PVC vent, the post-mitigation radon level chart. Include a guarantee: "We reduce radon levels below 2.0 pCi/L or we refund the install fee."
Prominent phone number, click-to-call button, and calendar widget must be present on mobile. Most radon searches happen on phones during home inspections or closing prep. If the prospect has to pinch-zoom to find your number, they call the competitor whose landing page renders correctly.

Audience Targeting: In-Market, Life Events, and Retargeting
In-market audiences for "home buyers" and "home improvement" can be layered onto Search campaigns to increase bids for users Google identifies as actively shopping. Test this in 30-day increments. If cost per lead stays flat or drops, scale the bid adjustment. If CPL climbs significantly, remove the layer.
Life event targeting for "recently moved" or "upcoming move" captures homeowners in transaction mode. Volume is low, conversion data takes time to validate. Run this as a separate campaign with a modest monthly budget to test.
Retargeting display ads to users who visited the landing page but did not convert should offer a discount or free consultation. Close the loop within 7 to 14 days before the prospect forgets about radon or books with someone else.
What Kills Radon Campaigns: Common Budget Traps
Running testing and mitigation keywords in the same ad group dilutes ad relevance and Quality Score. Google matches "radon test" searches to mitigation-focused ad copy and vice versa. Performance suffers. Separate campaigns, separate ad groups, separate landing pages.
Ignoring mobile bid adjustments when most clicks come from mobile wastes budget on desktop traffic that converts at lower rates. Optimize for where your traffic actually comes from.
Setting max CPC too low loses auctions. Mitigation terms require meaningful bids in competitive metros. Set max CPC too conservatively and the campaign becomes invisible. Budget constraints should limit daily spend, not max CPC.
Pausing campaigns during slow months erases Quality Score gains. When you reactivate, Google treats the campaign as new and you lose momentum. Better to reduce daily budget and keep the campaign live than to pause completely and start over.
