      The ads ran for about nine weeks and were then paused. In the weeks that followed, tracked enquiries per week fell by 71% against the weeks the ads were live, and almost no new won work came in. For a specialist trade, that is the plainest answer to how much of the phone traffic the ads were producing.

    How we did it

    1. Cut the searches that were never going to book

      726 unique search terms were read and sorted while the ads ran, so money that would have bought the wrong clicks went to the right ones.

    2. Measured calls and forms separately

      84% of Aussie Leak Detect’s enquiries arrived by phone, so calls were tracked as their own conversion and ad hours followed when the phone was answered.

    Each change uses the comparison period shown beside it.

    Aussie Leak Detect needed ads for customers who could describe a symptom as well as those searching for an inspection. We built separate messages for water, roof, gas, shower and pool leaks, with matching pages and enquiry tracking.

    The business

    Aussie Leak Detect is a specialist leak-detection business serving Sydney, the Central Coast and the Blue Mountains. Its technicians find hidden water leaks, roof leaks and gas leaks with acoustic, thermal and tracer-gas equipment, then give a written price before the repair starts. Most customers do not know where their leak is. They know the symptom: a damp ceiling, a water bill that keeps climbing, water coming through the roof.

    What we set out to do

    The brief was to put leak-detection ads in front of people with a leak, and show which of those enquiries turned into won work. Most enquiries in this trade arrive by phone, so a campaign judged only on form fills would miss most of the story. Every call and every form had to be traced from the ad to the job.

    What we built

    The account gives each leak type its own ads and message, so symptom searches sit alongside searches for a specific inspection service.

    • Underground and concealed-pipe water leaks
    • Roof leaks
    • Gas-leak detection
    • Shower and slab leaks
    • Pool leaks
    • Damp walls and ceilings

    Each set of ads lands on a matching page of the website, where the quote form already names the service. Calls from the ads are tracked, and every enquiry is matched to the client’s won-job records, so the return is measured on real work rather than on clicks or form fills.

    What happened

    The delivered account gives each leak service a clear route from search to enquiry. A customer searching for damp ceilings, hidden water leaks or gas-leak detection reaches relevant service content, a quote form and a tracked phone number. Enquiries are linked to the client's job records for follow-up.

    What informed the next steps

    Customers often describe a leak by its symptom. Ads for damp walls, ceiling marks and unexplained water use sit alongside technical leak-detection searches, so the message fits the problem the customer can see.

    Matching pages explain the inspection and give customers a quote form with the service already selected. Tracked phone enquiries help the team follow jobs that begin with a conversation.

    How we run accounts

    How we manage the campaign.

    We define the outcomes to track, test the enquiry paths and use what we learn to guide campaign improvements. SoudCoh Compound explains how that work is organised.

    • Rule 01

      Count real enquiries only

      The number it moves: True cost per lead

      We agree which calls, forms, bookings or sales count as a result, and a real test enquiry goes through every tracking path before the campaign goes live.

    • Rule 08

      Build on practical campaign experience

      The number it moves: Waste blocked before the first click

      Every change on an account like this one is written to that client's change history, and what it teaches, never the client's numbers, goes into the next account's starting point.

    If you want one of these

    What actually happens after the first call.

    Start with your goals and current setup. We review the opportunity, agree the work and plan the next stage with you.

    1. The call

      Thirty to forty-five minutes, free

      We discuss your services, customers, website and goals, then identify the most useful next step.

    2. Week 0

      The audit

      We review your website and advertising, then set out the opportunities, priorities and recommended scope.

    3. Week 1

      The build

      Everything the account needs before it can spend a dollar: what it will bid on, what it must never pay for, the ad copy, the assets, the landing pages and the tracking. It waits in our approval queue, and a real test enquiry goes through every tracking path before anything is live.

      Campaigns are created paused, every time, so you can read the whole build first. You activate when you are ready, not when we are.

    Book a call
    What did SoudCoh deliver for Aussie Leak Detect?

    Separate ads and messages for water, roof, gas, shower and pool leaks. Every call and form traced from the ad to the client’s won-job records. A connected website with a matching page and quote form for each leak service.

    What happened when the ads were paused?

    Weekly tracked enquiries fell by 71% against the weeks the ads were running, and almost no new won work came in. The comparison counts all tracked enquiries, including some calls from other sources, and is not adjusted for season.

    Which enquiries count as coming from Google Ads?

    An enquiry counts when it carries a Google Ads click or came through the phone number used only in the ads. Calls and website forms are both included, with test entries removed.

    What do the results in this Aussie Leak Detect case study measure?

    Campaign results describe the enquiries or job outcomes reported for the client. Each figure identifies what it measures.

    Which records support these results?

    Result basis: Campaign delivery. The labels distinguish advertising conversions, call/form enquiries and won-job revenue. Enquiry events can include repeat calls; booked jobs are reported separately.

    Would this work for plumbing businesses like mine?

    We assess your service area, competition, margins and customer value, then build a plan around the opportunities in your business. The first call establishes the priorities, budget and tracking for that work.

    How would you plan this for my business?

    We start with your goals, service area, competition and customer value. From there, we recommend the channels, website improvements and tracking that fit your next stage of growth.

    How much would this cost to run?

    Two separate numbers. Your ad spend goes to the platform, and what it needs to be depends on how competitive your market is and how many jobs you want — we recommend a minimum of A$5,000 a month for most businesses, and the largest companies we work with currently invest up to A$30,000 a day in advertising, with enterprise programmes above that. Our management fee is separate, isn't published and is custom-built around the work — contact us for packages. The first call is free and you leave it with a real figure for your situation.

    Ready to plan your campaign?

    Thirty minutes on your numbers, and a written list of what we would change first. Yours to keep either way.
