A strong business, an invisible web presence

Peak Plumbing had the crews, the reviews, and the referrals — but when a Denver homeowner searched "plumber near me," Peak was nowhere to be found.

Primary pain point

Competitors with weaker service records and fewer actual reviews outranked Peak across every high-intent keyword. New customer acquisition relied almost entirely on word-of-mouth, capping growth.

Citation chaos

The business name, address, and phone number appeared in 14 different variations across directories — a signal Google interprets as untrustworthiness. The GBP listing hadn't been touched since 2019.

No content strategy

The website had a single, thin homepage and a contact form. There were no service pages, no neighborhood landing pages, and no structured data. Google had no local relevance signals to act on.

Three pillars, one unified local presence

Rather than chasing rankings with quick fixes, we built a compounding local authority engine across the three areas that matter most to Google's local algorithm.

01

GBP & citation authority

Fully rebuilt the Google Business Profile — categories, service menus, photos, and Q&A — while correcting NAP data across 60+ directories.

02

Hyperlocal content architecture

Built 24 optimized service + neighborhood pages targeting "plumber [neighborhood]" and "emergency plumber [zip]" queries throughout the metro.

03

Review velocity & reputation

Implemented a post-job review request workflow via SMS and email, tracking every review and responding within 24 hours — to signals and sentiment alike.

We used to get maybe two or three calls a week from people who found us online. Now my phone doesn't stop. I had to hire two more technicians just to keep up with the demand — and that's a good problem to have.

What made this work

1

Citation accuracy is foundational, not optional

Inconsistent NAP data actively suppressed Peak's local pack eligibility. Fixing it before doing anything else unlocked the baseline trust Google needed to surface the listing.

2

Neighborhood pages outperform generic city pages

Targeting "plumber Aurora" and "plumber Lakewood" as distinct pages — each with unique content and local schema — consistently outperformed the generic city-wide approach competitors used.

3

Review velocity is a sustained effort, not a launch campaign

The SMS-based review workflow ran every week for 12 months. Recency of reviews matters as much as volume — a steady drip beat a one-time push.

4

GBP engagement signals reinforce ranking

Weekly posts, answered Q&As, and photo uploads kept the listing active. Google treats an engaged GBP as a quality signal — and the data bore that out in map pack appearances.
