The situation

Halstead & Kerr Plumbing had been in business for eleven years on a strong local reputation, but almost none of that reputation showed up online. A search for "plumber near me" or "emergency plumber Sacramento" put three competitors in the map pack before Halstead & Kerr appeared at all, and the website ranked on page three or worse for nearly every service and city page it needed.

Newer competitors with weaker reputations but better-optimized profiles were consistently winning the calls Halstead & Kerr should have been getting. And when customers started asking ChatGPT and Google's AI Overviews for plumber recommendations, Halstead & Kerr wasn't mentioned once — the business was invisible in the exact place more of its future customers were starting to look.

The owner had relied on truck wraps and word-of-mouth for over a decade. That was no longer enough to keep the schedule full.

"We were the best-reviewed plumber in three of our service cities and you'd never have known it from Google."

The approach

Three channels, built as one system.

Local SEO

  • Full technical audit and site cleanup
  • Rebuilt 40 service + city page combinations around real search demand
  • Corrected NAP inconsistencies across 60+ directories
  • Structured data markup for services, reviews, and service areas
Google Business Profile

Owning the map pack

  • Rebuilt categories and service menu to match search intent
  • Weekly posts and updated photo library
  • Review generation system for techs to use on-site
  • Ongoing Q&A and message monitoring
AI Search (GEO)

Getting recommended by name

  • Structured FAQ content written for how AI models parse and cite answers
  • Consistent, corroborating citations across the directories AI tools pull from
  • Review and reputation signals reinforced across every listing
  • Ongoing tracking of AI Overview and chatbot mentions by query

Why the AI mentions mattered most

Map pack rankings brought the steadiest volume, but the AI Overview and ChatGPT mentions closed jobs at a noticeably higher rate — those customers arrived already having been told Halstead & Kerr was the trusted option, with far less price-shopping than a standard search click.

"Within four months our phone started ringing with people who'd never heard of us before. By month eight, our office manager said new customers were mentioning that 'the AI thing' recommended us. We didn't even know that was possible."
