Client Overview


A regional home improvement and plumbing company in the UK approached YellowInk Digital to increase inbound leads from local customers. Their digital presence was outdated and under-optimized for location-based queries.

The Challenge

  • No local landing pages or city-specific targeting
  • Poor Google Business Profile visibility
  • Weak ad targeting with low ROAS
  • Untracked inbound calls and form submissions
  • High cost per lead and low volume of qualified prospects

The Strategy

Location-Based SEO Overhaul

  • Built separate service area pages (e.g., “Plumbers in Kent”, “Boiler Installation London”)
  • Added local schema, FAQs, and map embeds
  • Optimized Google Business Profile with reviews and Q&A prompts

Hyper-Targeted PPC Campaigns

  • Launched tightly themed ad groups for top services
  • A/B tested ad copy and extensions
  • Ran call-only campaigns for urgent services

Lead Tracking & Funnel Optimization

  • Integrated CallRail to track phone leads
  • Used GA4 and GTM for form conversions
  • Built custom thank-you page to measure high-intent contacts
