CONTEXT
Core Plumbing is a family-owned plumbing company serving San Diego and surrounding communities, offering residential plumbing, repairs, remodels, new construction, and 24/7 emergency services. This made Google Search particularly valuable for reaching homeowners actively looking for a plumber.
The goal was to capture that local demand while keeping the $200/day budget focused on high-intent searches most likely to generate leads.
CHALLENGE
The account covered a wide range of services, from emergency repairs and drain issues to water lines, fixtures, and larger plumbing projects. Each service had different search intent, making it important to control keyword relevance, search terms, ad-group performance, bidding, and location-level results.
The main challenge was making the $200/day budget work efficiently across these different demand areas.
APPROACH
We rebuilt the campaign around 11 tightly themed STAG and SKAG ad groups, aligning keywords more closely with specific plumbing services and user intent. We combined this with Maximize Conversions, a $58 target CPA, negative keyword optimization, search-term analysis, and ongoing bid and budget adjustments.
Location performance was also reviewed continuously so more attention could be given to the searches and areas producing stronger conversion signals.
RESULTS
From Feb. 6 – Mar. 20, 2025, the campaign generated 1,745 clicks from 19,856 impressions and 156 conversions from approximately $10,280 in ad spend. Average CPC was $5.89, while ads appeared in the absolute top position 26% of the time and in the top section 57% of the time.
Using the supplied $300 average lead value, the campaign represented approximately $46,800 in modeled revenue, resulting in a reported 4.55X ROAS and 355% ROI.
KEY TAKEAWAY
The results came from tighter service-level structure, stronger keyword intent, and continuous optimization, allowing the $200/day budget to focus on the searches most likely to generate high-intent local plumbing leads.
