    State Choice Plumbing: plumbing services with a detailed local structure

    The case study

    What moved for State Choice Plumbing.

    The short list

    1. The served groups include hot-water replacement and systems, toilets, kitchen plumbing, gas work, leaking taps, showers, leak detection, pool leaks and stormwater. Gas-cooktop installation and heat-pump hot water appear as more specific installation categories.
    2. Problem-led groups include no hot water, leaking showers, water leaks and roof or gutter leaks. Quote and pricing-related groups appear alongside them, reflecting customers who want to understand the callout or job scope before proceeding.
    3. The case describes verified advertising scope, with no unpublished performance total or unverified uplift.

    The campaign decisions and results behind this work.

    A specific service brief

    State Choice Plumbing’s account combines service and location campaigns for Sydney plumbing enquiries. Its service detail accommodates planned household work and the familiar symptoms that prompt a customer to seek help.

    SoudCoh’s Google Ads work gives that offer a defined search-campaign structure. The account records separate service groups with advertising delivery, so the work can be described through the actual requests it covers.

    The advertised services

    The served groups include hot-water replacement and systems, toilets, kitchen plumbing, gas work, leaking taps, showers, leak detection, pool leaks and stormwater. Gas-cooktop installation and heat-pump hot water appear as more specific installation categories.

    Problem-led groups include no hot water, leaking showers, water leaks and roof or gutter leaks. Quote and pricing-related groups appear alongside them, reflecting customers who want to understand the callout or job scope before proceeding.

    What the structure makes clear

    This is a broad household service brief, but the account does not leave it as one broad label. The service, symptom and local enquiry structure give the work a more useful shape. An advertising group about a quote or callout price is not a blanket pricing promise for every job; the final scope still belongs in the customer conversation.

    The point of this service detail is relevance. It gives a prospective customer more than a business category: it identifies the kind of work they can ask about. For the business, the same distinctions provide a practical way to discuss the enquiry mix and the information needed before a quote or booking. It separates the customer’s immediate question from the wider service range the business offers.

    The website alongside the campaign

    The website case shows the public service presentation separately, with real page captures and the enquiry experience. It provides a useful companion to this account-level view of the advertised services.

    What the results measure.

    The definitions behind the campaign results, from enquiries and conversion rates to advertising spend.

    Conversion
    An action recorded under the account’s conversion setup, such as a tracked call, form submission, booking or purchase. Platform call/form enquiries are described separately in the study; repeat calls can be separate events, so enquiries are not necessarily unique people.
    Cost per job · cost per lead
    Advertising spend divided by the relevant recorded enquiry or job count. The study identifies the denominator. Enquiry cost is considered alongside lead quality and job value.
    Conversion rate
    The share of people who clicked the ad and then did the thing. A high click count with a low conversion rate usually means the ad and the page are promising different things.
    Ad spend
    Money spent on the advertising platform. The enquiry costs and revenue-to-ad-spend figures here exclude agency fees and the cost of delivering the client’s service.
    The measurement window
    The period covered by the result, with spend and outcomes drawn from the same reporting window.
    A starting point
    Starting values appear beside the resulting figure when the account history is available.
    Qualified lead
    An enquiry that matched the service and the service area, so it was worth someone picking up the phone for. Where a study says qualified, somebody checked.
    An anonymised client
    Government, council and cultural-institution engagements are published as sector and jurisdiction only. The work and the measured outcome are described in full; the organisation is not named.
    SoudCoh Compound™

    This page exists because of two of the six stages.

    Compound is how our team works on any account — six stages every change passes through. Two of them are why there is anything honest to publish.

    • Meter

      If it can't be measured, it doesn't get bought.

      Before a dollar moves, every action worth money to the business is tracked as itself — calls, forms, bookings, purchases — with values attached. Without that stage there is no honest number to publish afterwards.

    • Ledger

      Every change we make becomes a record you can open.

      Every change lands in a dated record as it happens — what was added, what was stopped, what was rewritten and what it cost. Writing this page afterwards was reading a file, not reconstructing a memory.

    Read all six stages
    If you want one of these

    What actually happens after the first call.

    No mystery and no lock-in before you have seen anything. This is the sequence every account on this site went through.

    1. The call

      Thirty to forty-five minutes, free

      What you sell, who buys it, and what one customer is worth to you. No deck. You leave with a real number for your situation rather than a range.

    2. Week 0

      The audit

      We open your account — or your competitors' ground, if you do not have one yet — and write down every leak we can find. That list is yours whether or not you work with us.

    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. A second person checks all of it before anything is live.

    4. Day one

      You press go

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

    5. Days 1–14

      The clean

      The busiest fortnight your account will ever have. Search terms read daily, waste negated, early winners promoted, ad copy iterated against what is actually being served.

    6. From there

      Rhythm

      Weekly optimisation, reporting on a fixed cadence whether the news is good or bad, and a proper conversation each quarter about where the next block of budget should go.

    Before you ask us anything

    Here is what everybody asks first.

    FAQ

    The questions this raises.

    How the results were measured and how the approach could apply to plumbing businesses.

    The first call is free and there is no deck.

    Book a call
    What services does the campaign cover?

    The served groups include hot-water replacement and systems, toilets, kitchen plumbing, gas work, leaking taps, showers, leak detection, pool leaks and stormwater. Gas-cooktop installation and heat-pump hot water appear as more specific installation categories. Problem-led groups include no hot water, leaking showers, water leaks and roof or gutter leaks. Quote and pricing-related groups appear alongside them, reflecting customers who want to understand the callout or job scope before proceeding.

    Why does the account separate these enquiries?

    This is a broad household service brief, but the account does not leave it as one broad label. The service, symptom and local enquiry structure give the work a more useful shape. An advertising group about a quote or callout price is not a blanket pricing promise for every job; the final scope still belongs in the customer conversation.

    Does this case publish a performance result?

    This story focuses on the verified campaign service structure. It does not assign an unverified cost per lead, revenue return or customer outcome to the work.

    What do the results in this State Choice Plumbing case study measure?

    Campaign figures come from the advertising account and, where stated, SoudCoh.app enquiry and won-job records. Each result identifies the action or revenue it measures.

    Which records support these results?

    Result basis: Verified campaign service scope. 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.

    Why does this study show a result but not a starting point?

    Where a comparable earlier result is available, the study shows both values. New accounts report their launch result, with the tracking basis explained alongside it.

    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.

    Explore the services behind this engagement, alongside our work for plumbing businesses.

    The briefing behind the work.

    The case study records what happened. These explain the channel, measurement or operating decisions behind the result.

    A result is only useful when the owner can see where it came from and what changed. That case is argued in What to ask when an agency cannot explain the account.

    Why a clean account can still report the wrong outcome when the conversion definition is wrong. The other half of it is set out in The conversion-tracking errors that duplicate sales and GST.

    The work behind this one is written up in full under plumbing accounts, written up for plumbers, and the ninety-day plan that produced results like these sets out the sequence in order.
