This plumbing company had been serving their city for over a decade with excellent reviews and repeat customers — but newer, more digitally-savvy competitors were stealing the first-call advantage.

The core problem wasn’t their reputation. It was that AI search systems had no structured way to understand or recommend them.

What We Found

  • No schema markup on their website
  • Inconsistent NAP data across 40+ directories
  • Zero presence in AI-generated local service recommendations
  • Generic service pages with no entity-level content

What We Built

We deployed all four authority layers over a 60-day sprint:

  1. Authority Asset Layer — Fixed all citation inconsistencies, rebuilt their Google Business Profile, and implemented full LocalBusiness schema markup
  2. Authority Context Engine — Rewrote their service pages to answer the exact questions AI models ask when evaluating plumbing companies
  3. Authority Infrastructure Suite — Built a structured citation network across 60+ high-authority directories
  4. Local Authority Expansion — Created neighborhood-specific authority content for every zip code they serve

Results at 90 Days

By day 90, they appeared in the top recommendation slot in ChatGPT and Perplexity for “best plumber in [city]” and related queries. Inbound calls increased 89% and the quality of leads improved dramatically — buyers arriving already convinced they were the right choice.
