    The case study

    What moved for Aussie Plumbing.

    The short list

    1. $98.89 per tracked Google-attributed call or form enquiry.
    2. Phone and form events are measured against advertising spend in the same window.
    3. Service-specific campaigns connect the ad to the website and enquiry journey.

    The figures describe their stated measurement basis and selected window; they are not a forecast.

    Calls and forms, measured together

    Aussie Plumbing recorded $98.89 per Google-attributed call or form enquiry in the selected measurement window. The figure combines Google Ads spend with the enquiries recorded in SoudCoh.app, rather than relying only on the Google Ads conversion column.

    Campaigns built around the service

    Blocked drains, hot water systems and urgent plumbing have different enquiry journeys. SoudCoh connects the service message, landing page and follow-up around the work the business wants to grow. The aim is to improve return from useful work as well as manage the cost of the first enquiry.

    The website carries the message

    A visitor should find the service they searched for and a clear route to contact. We build service and local-area content around the client’s offer, with enough detail to make the business feel established and to help the visitor decide.

    How the result is calculated

    Spend and enquiries use the same measurement window and account timezone. Cost per enquiry includes Google-attributed phone-call and form events recorded in SoudCoh.app; linked CRM call duplicates and hidden spam are excluded. Repeat calls can remain separate enquiries, so this is not a count of unique customers or booked jobs.

    Putting the result in context

    This selected result is a record of this account’s performance. Enquiry volume, job value and lead quality are separate questions, and performance can change with demand, budget and the work being targeted.

    The earlier account record

    Read the historical Google Ads case study. Its conversion-based figures describe a different window and reporting definition; they are not a like-for-like baseline for this call-and-form result.

    What every number on this page actually means.

    Marketing words get used loosely, and a loose word can make a small result look like a big one. Here is exactly what we mean by each of them.

    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 selected period represented by the result. Exact calendar dates can be withheld for client privacy; the underlying spend and outcomes are checked against the same window.
    A starting point
    Where a study knows what a figure was before the work began, that number is printed next to the one it became. Where the account had no history to compare against, the result is printed on its own rather than measured from a number nobody recorded.
    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.

    One more, because it matters most: nothing on this page is a guarantee. It is a record of what happened on one account, in one market, at one budget.

    What this study cannot tell you is what the same figure looks like on your account — so what a lead costs you at your click price, with your own click price and close rate. It takes about a minute and asks for nothing.

    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.

    Here is what everybody asks first.

    The questions this raises.

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

    What cost per lead has SoudCoh achieved for Aussie Plumbing?

    $98.89 per Google-attributed phone-call or form enquiry in this selected window. It is an account-specific achieved result, not a quoted lead price or guarantee.

    Are phone calls included in this figure?

    Spend and enquiries use the same measurement window and account timezone. Cost per enquiry includes Google-attributed phone-call and form events recorded in SoudCoh.app; linked CRM call duplicates and hidden spam are excluded. Repeat calls can remain separate enquiries, so this is not a count of unique customers or booked jobs.

    Are the figures in this Aussie Plumbing case study real?

    Campaign figures come from the advertising account and, where stated, SoudCoh.app enquiry and won-job records. Website studies document the delivered design separately. Each study explains what its result measures; ask us about the source behind a figure on your first call.

    How were these numbers measured, and over what window?

    The headline figure covers Selected measured result · AUD, and every other figure on the page is printed beside the period it belongs to. Results describe selected measurement windows, with exact trading dates kept private. The study identifies whether it measures advertising conversions, tracked call/form enquiries or recorded won-job revenue. Tracked calls can include repeat enquiries; they are not automatically unique people or booked jobs.

    Would this work for plumbing businesses like mine?

    We cannot promise you the same numbers, and nobody honestly can. What this page tells you is what was achievable in that market, at that budget, for that service. Your competition, your service area, your margins and what one customer is worth to you all move the answer. On the first call we build the picture from your figures rather than someone else's, and if the honest answer is that this channel is wrong for you right now, we will say so.

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

    Because in most of these engagements there was nothing reliable to start from. A brand-new advertising account has no history, and a business that was tracking enquiries on paper or in a spreadsheet has no comparable figure either. Where a real before-number exists we print it next to the after-number, so you can see the movement rather than take our word for it. Where it does not, we print the result on its own. Back-solving a starting point from a percentage would make the page look better and mean less.

    Would my business get the same result?

    We cannot tell you that, and nobody honestly can. What this page tells you is what was achievable in that market, at that budget, with that service. Your competition, your service area, your margins and what a customer is worth to you all move the answer. On the first call we build the picture from your numbers rather than from someone else's, and if the honest answer is that this channel is wrong for you right now, we will say so.

    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 — the smallest companies we work with invest a minimum of A$3,000 a month, and our largest clients run multiple eight figures a month across paid channels. Our management fee is separate and scales with the work. The first call is free and you leave it with a real figure for your situation.

    The briefing behind the work.

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

    The external entity data underneath any local-service acquisition programme. That case is argued in The citation inconsistencies that still move local rankings.

    Why the primary and secondary categories must match the work a business actually wants. The other half of it is set out in Google Business Profile categories as a silent rank constraint.

    The work behind this one is written up in full under plumbing accounts, written up for plumbers, and the six stages every change on this account passed through sets out the sequence in order.
