About the client

About Sigma Plumbing

Sigma Plumbing is a locally owned plumbing business based in Merrylands, working across Western Sydney and the suburbs around it. Its licensed plumbers answer the phone 24 hours a day, 7 days a week, weekends and public holidays included.

The team looks after homes, businesses, strata buildings and commercial sites. The work runs from a dripping tap to a burst pipe at midnight: blocked drains, hot water systems, gas fitting, sewer and stormwater, pipe relining, roof and gutter repairs, and planned maintenance for strata and property managers.

Sigma’s way of working is simple. Upfront quotes before the job starts, a courtesy call before the plumber arrives, and a tidy site when they leave. It’s a hands-on business that people call when something has gone wrong and they need it fixed properly.

The website

The Sigma Website

The website is where every search lands, so it has to work hard for someone with water on the floor. Their phone number sits at the top of every page, and the free quote form is never more than a scroll away.

Each key suburb and each main service now has a clear page of its own. Someone in Blacktown with a blocked drain lands on a page written for Blacktown, not a generic one written for everywhere.

Starting point

Where Sigma Started

Sigma already had the hard part sorted: licensed plumbers, a 24/7 phone line and a list of customers who call them back when the next job comes up. Most of that work came through word of mouth and repeat clients.

The next step was search. Every day, people across Western Sydney type “plumber” and their suburb into Google, often in the middle of an emergency. Together with the Sigma team, we set out to put the business in front of those searches.

Goals

What Sigma Wanted From Search

  1. Reach page 1 for “plumber” searches in the suburbs Sigma serves most.
  2. Be found fast for emergency searches, when someone needs a plumber now.
  3. Give each key suburb and service its own page, so Google could match a local search to the right one.
  4. Keep the website and Google Business Profile active with fresh content every month.

The challenge

Ready to Be Found Beyond Word of Mouth

Plumbing is one of the busiest local searches in Sydney. Plenty of businesses want the same calls, and Google only puts ten of them on page 1.

Each of those searches is someone who needs help today. A homeowner in Seven Hills with a blocked drain is ready to book. So is a strata manager in Parramatta with a leak in a common area. Google shows them the plumbers it trusts most for that search, in that suburb.

Getting onto that first page takes more than a good homepage. It needs a page for each suburb and service, content Google can read, an active local listing, and other websites pointing back to the business.
