The Account We Inherited
A1 Mold Testing & Remediation works in a high-intent category.
- People search because they have an immediate concern: a musty odor, visible
- The demand was there, but the efficiency was missing.
- In the comparison period, the account spent $17,042 to produce 95 conversions, a $179 cost per conversion and a 1.84% conversion rate, against 650,876 impressions of largely low-intent traffic.
Money was being wasted on clicks that never turned into qualified conversions. The message was clear: make sure that paid search becomes an effective means of getting qualified conversions from those already searching for professional mold removal services.
Objective
- Increase measurable Google Ads conversions from high-intent users.
- Reduce average CPC and cost per conversion.
- Strengthen conversion rate by aligning paid-search intent with service-led landing pages.
- Maintain meaningful coverage across the Omaha and Lincoln markets while controlling wasted spend.
Our Approach
- Prioritized search intent tied to mold testing, inspection, assessment, removal, and remediation, rather than treating every click equally.
- Aligned ad messaging with A1’s strongest trust signals: certified expertise, 25-plus years of experience, laboratory analysis, and documented assessments.
- Tightened relevance between the search need, the ad promise, and the landing-page experience to lift conversion intent.
- Let spend concentrate where conversions were strongest rather than chasing volume, using conversions and cost per conversion as the primary optimization signals.

What the Numbers Mean
The account did not simply do more; it did better with less. Impressions fell 91% and clicks 50% by design, as low-intent traffic was cut, while conversions rose 380% and the conversion rate climbed from 1.84% to 17.59%. CTR rose from 0.79% to 4.35%, a sign of a stronger match between the search, the ad, and the page.
Business Impact
For a business built around expert assessment, the quality and cost of each conversion matter more than raw traffic. At 456 conversions and $9.02 each on a fraction of the prior spend, paid search became a cheaper, more reliable source of qualified actions from people already looking for professional mold and indoor-environment help.
With services spanning solo airport runs to group charters, there is room to open more intent-led paths from the same efficient base.

Where A1 Stands Now
In six months, A1 turned Google Ads from a high-cost, low-conversion channel into an efficient acquisition engine: 456 conversions at $9.02 each, on 76% less spend than before.
The win was not more traffic, since impressions and clicks were deliberately cut. It was concentrating spend on the high-intent mold and assessment searches that convert, so the account is now cheaper to run and produces far more qualified actions. The work is ongoing.
