The challenge

Four trades, hundreds of suburbs.

Network Plumbing, Electrical & Air Conditioning has served Sydney since 1988. Every one of its trades is fiercely contested in search, and customers don’t search for “plumber” — they search for a plumber in their suburb, right now.

That means the site has to rank for thousands of trade-and-location combinations at once, against both national brands and hyper-local operators.

The approach

A keyword map for every trade and every area.

Keyword research and mapping. In August 2022 we built the keyword research and mapping document that has guided the campaign since — every trade, service and service area matched to the page that should rank for it.

Local SEO at scale. The suburb and location pages were structured around that map so each one targets real local demand, with a Wollongong expansion following the Sydney core.

Ongoing optimisation and reporting. Monthly reporting tracked progress across every trade. In 2026 the work moved into a deeper phase: a suburb-page indexation audit across 79 pages, site-speed optimisation, canonical and redirect clean-up, rewrites of the head pages for “plumber Sydney” and electrician terms, and a new link-building programme.

The results

Thousands of new page-one rankings.

Keywords ranking in Google’s top 10 grew from 967 in August 2022 to 4,676 by October 2025, with top-5 rankings rising from 430 to 2,826. Total ranked keywords grew from 5,611 to a peak of 17,440.

At its peak in February 2025, estimated organic traffic reached 16,697 visits a month, up from 1,474 when we started — traffic that would cost an estimated $129,684 a month to buy through Google Ads.
