    How we measured

    The 5.2× result covers the first 30 days of ads. It divides agreed won-job value from traced Google Ads enquiries by spend for those same days, rounded down. This is a launch-period result, not an ongoing return; revenue is before costs and agency fees.

    Bayside Plumbing, from the brief to the result in 4 short slides.

    1. The business

      A Sydney plumber covering drains, hot water, gas and leaks

      Bayside Plumbing handles everyday and urgent plumbing across Sydney: blocked drains, hot water, gas fitting, leak detection, taps, toilets and showers, for homes and for cafés and restaurants.

    2. The problem

      Ads only matter if they turn into booked plumbing work

      Clicks and calls are easy to count. Bayside needed to know which enquiries became won jobs, at what value, and what each campaign returned against its ad spend.

    3. What we built

      Separate campaigns for suburbs and services, tied to won jobs

      One campaign answered searches naming a Sydney suburb and another answered service searches, each landing on a matching page. Every call and form was traced to the ad and matched to won jobs.

    4. What happened

      A 5.2× return in won jobs in the first 30 days

      Won job value reached 5.2 times the ad spend in the first 30 days and 5.6 times in the first fortnight. Nearly 2 in 5 Google Ads enquiries became won jobs.

    What the data showed

    Details from the Bayside Plumbing project. Open a card for the finding and its source.

    • Timing

      1.5×

      Enquiries that arrived before midday became won jobs 1.5 times as often as later ones

      • Before midday42%
      • Midday or later28%

      About 42% of Bayside's Google Ads enquiries made before midday became won jobs, against 28% from midday on. A morning enquiry leaves more of the day to quote and book the job. Answering those enquiries quickly is where this points.

    • Value

      1.5×

      A job won from a website form was typically worth 1.5 times one won from a phone call

      • Typical job from a website form1.5×
      • Typical job from a phone call1×

      Phone calls still brought in more than half of Bayside's won job value, so the phone stays the main way in. But the typical job won from a website quote form was worth about 1.5 times the typical job won from a call. A form that asks for the suburb and the work needed gives those larger jobs an easy start.

    Over the first 30 days of Google Ads, Bayside Plumbing recorded 5.2× return on Google Ads spend in agreed won-job value. Separate Google Ads campaigns for searches naming a Sydney suburb and for service searches.

    The business

    Bayside Plumbing is a Sydney plumbing business. Its work runs from blocked drains, hot water and gas fitting to leak detection, taps, toilets, showers and vanities, for homes as well as cafés and restaurants.

    Most of the won work that came through Google Ads started with someone searching on a mobile phone, so the pages and contact options had to work on a small screen.

    What we set out to do

    The goal was simple to state: Google Ads that bring in plumbing work worth more than they cost, measured in won jobs rather than clicks or calls. That meant tracing every enquiry back to the ad that produced it, and matching it to the jobs Bayside actually won, at the agreed price.

    We also wanted to learn which searches, times of day and contact methods produced the best work, so the budget could follow them.

    What we built

    We split the account by how people search. One campaign answers searches that name a Sydney suburb. Another answers service searches: blocked drains, emergency plumbing, hot water, gas fitting, leaks, taps and toilets. A dedicated drainage campaign has just been added.

    Each ad lands on a page that matches the search. The blocked-drains page opens with a quote form already set to blocked drains, and suburb pages lead with local service information. On a phone, a large call button sits just under the introduction.

    The blocked-drains page carries the search straight into a matching quote form.

    Every call and website form is traced to Google Ads and lands in the client's job records. When Bayside wins a job, it marks it won with the agreed price, so every figure on this page comes from real job outcomes. See the pages, mobile layout and enquiry options in the Bayside Plumbing website case study.

    What happened

    Bayside Plumbing recorded 5.2× in agreed won-job value against Google Ads spend over first 30 days of Google Ads. Separate Google Ads campaigns for searches naming a Sydney suburb and for service searches. The result uses enquiries traced to Google Ads and the client’s recorded won jobs, measured against ad spend for the same period. It is revenue before service costs and agency fees.

    What informed the next steps

    Unless noted, these findings cover every Google Ads enquiry since ads began.

    Forms brought larger jobs, calls brought most of the value

    The typical job won from a website quote form was worth about 1.5 times the typical job won from a phone call. Calls still brought in more than half of won job value, so both routes stay open and easy to use.

    Most of the value started on a phone

    62% of won job value came from people who clicked the ad on a mobile phone. For a plumber, a clear call button and a short form that works on a small screen are where the work starts.

    The return is spread across many jobs

    For a plumbing business with several services or service areas, our Google Ads management plans campaigns around the jobs you want to win.

    Key campaign decisions
    • Bayside's Google Ads returned 5.2 times the ad spend in won jobs over the first 30 days, and 5.6 times over the first 14.
    • No single job made up more than 14% of won value since ads began, so the result rests on many jobs, and 62% of won value came from people on a mobile phone.

    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
    Recorded conversion actions divided by ad interactions, usually clicks. The study identifies which actions count toward its rate.
    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 assessed against the agreed service, service area and customer requirements.
    An anonymised client
    A project published without the client’s name. The page identifies its sector and explains the scope of the work.

    Put your own numbers to work: 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.

    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

    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
    How was the 5.2× return measured?

    We traced every call and website form to Google Ads and matched each enquiry to the client's job records. Won value is the agreed price of each job the client marked as won. That total was divided by Google Ads spend over the same 30 days and rounded down. Test entries were removed.

    How quickly did enquiries turn into won jobs?

    For enquiries from the third week of ads onward, when wins were recorded as they happened, half of the jobs won were marked won within three days of the first enquiry, and every job won so far within a week.

    What did SoudCoh deliver for Bayside Plumbing?

    Separate Google Ads campaigns for searches naming a Sydney suburb and for service searches. Service and suburb landing pages with a quote form and a prominent call button on mobile. Every call and website form traced to the ad and matched to the client's won jobs.

    What do the results in this Bayside Plumbing 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: First 30 days of Google Ads. 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.
