Case Study / Local Plumber – Greater London
From Ad-Dependent Leads to Predictable Organic Phone Calls
Executive Snapshot
This Greater London plumbing business relied almost fully on Google Ads to generate calls. When ads paused, enquiries dropped sharply. Organic visibility was weak, Maps presence was inconsistent, and competitors were winning high-intent local searches.
We rebuilt their local SEO around location intent, service intent, and phone calls, not traffic volume. Within 4 months, organic calls increased sharply, Maps visibility improved, and reliance on paid ads reduced without increasing budget.
Client Background
- Industry: Plumbing (Local Service Business)
- Location: Greater London
- Services: Emergency plumbing, repairs, installations
For plumbers, one missed call often means a lost job. The business needed consistent visibility where people search with intent to call now.
The Real Problem (With Numbers)
Before SEO work began:
- 82% of enquiries came from Google Ads
- Organic search produced fewer than 15 calls per month
- The business appeared in the top 3 Map results for only 2 service areas
- Average cost per lead via ads was £38–£45
- No clear tracking between calls, forms, or locations
Ad spend kept the phone ringing, but profit margins were under pressure.
Goals & Success Metrics
We agreed measurable, business-first goals.
- Increase organic phone calls by at least 100%
- Improve Google Maps visibility across priority postcodes
- Reduce paid-ad reliance by 30%+
- Improve enquiry quality, not just volume
- Track calls accurately by source
No vanity metrics. Calls, locations, and booked jobs only.
Constraints & Challenges
- Highly competitive London plumbing keywords
- Emergency searches with strong buyer intent
- Multiple service areas with uneven demand
- Competitors with long-standing Map dominance
The strategy had to be targeted and efficient.
