- Selected launch result
Selected results from the client’s advertising and, where stated, SoudCoh.app records. The case study explains the measurement basis. Results are account-specific and do not predict another business’s performance.
What would this look like on your account?
Different market, different budget, different numbers. The first call is where we work out whether the same approach fits yours at all.

The case study
What moved for Bayside Plumbing.
The short list
- The aim is a better mix of work, alongside a sensible cost per enquiry. A cheap enquiry that the business cannot service is of little use. The service offered, customer’s location and urgency all shape the advertising and the page.
- Bayside’s website presents the business with a clear brand, useful service detail and visible contact options. The design helps a customer understand who they are calling before they enquire.
- The selected launch result is approximately six times Google Ads spend in recorded won revenue. This is a revenue-to-ad-spend measure, before service delivery costs and agency fees; it is not net profit or a guarantee for another business.
The figures describe their stated measurement basis and selected window; they are not a forecast.
A plumbing campaign measured beyond the enquiry
Bayside Plumbing’s brief was to attract plumbing work worth taking on. SoudCoh paired Google Ads with a dedicated website and enquiry reporting, connecting the advertising decision to the work that follows the call.
The campaign focuses on the services and locations the business wants to grow. Blocked drains, urgent plumbing and hot water enquiries call for different messages, even when the same team handles the job.
Higher-value jobs guide the brief
The aim is a better mix of work, alongside a sensible cost per enquiry. A cheap enquiry that the business cannot service is of little use. The service offered, customer’s location and urgency all shape the advertising and the page.
We review the journey from search to enquiry and from enquiry to a recorded won job. That gives the team a way to discuss return on ad spend alongside lead volume.
A website that supports the campaign

Reading the revenue result
The selected launch result is approximately six times Google Ads spend in recorded won revenue. This is a revenue-to-ad-spend measure, before service delivery costs and agency fees; it is not net profit or a guarantee for another business.
Exact client spend and revenue remain private. SoudCoh.app gives the team a shared view of advertising spend, recorded enquiries and job outcomes, with the attribution basis kept consistent.
Recorded won-job revenue is attributed to Google Ads enquiries acquired within the matched measurement window. It is recorded job value, not a statement of cash collected, net profit or margin.

That is one account. Yours is a different one.
We read your ads, your search presence and your tracking the same way this one was read, and tell you what we would change first.
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 the ROAS you have to clear to break even, with your own click price and close rate. It takes about a minute and asks for nothing.
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.
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
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 callCan SoudCoh help a plumber attract higher-value jobs?
Yes. Bayside’s campaign and website are organised around the plumbing services and locations the business wants to grow, with enquiry quality and recorded job outcomes reviewed alongside cost per lead.
Is six times ad spend the same as profit?
No. The selected Bayside result compares recorded won revenue with Google Ads spend. It excludes job delivery costs and agency fees and does not represent net profit.
Are the figures in this Bayside 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 launch result, 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.
More accounts, same discipline.
Studies from the same kind of work, so you can see how the pattern holds across different businesses.
