    How we work together

    Nothing gets wasted twice.

    SoudCoh Compound™ is how our team runs an account. We read the numbers together, agree what to change, get a second person to check it before it goes live, write down what happened, and sit down with you on a fixed cadence to talk about it.

    Most agencies start every client at zero. We don't. Compound is six gates we take every dollar and every change through — and then a move that isn't a gate at all: we write what we learn on your account into the rules that guard every other account we run. They are gates, not pillars: sequential stages of one change, not parallel attributes of a company.

    To be exact about what travels: our learnings, never your data. We carry de-identified structure between accounts and nothing else — negative terms, policy rejections, URL-routing rules, compliance guards. We never carry spend, conversion data, bids or creative. Nothing that is yours leaves your account. On day one you get every rule we have already written, applied to your business rather than recycled from anyone else's.

    Behind each one there is a person with a name: an analyst reading the data, a media buyer making the call, someone in tracking proving the number is real, a writer and a designer arguing about the page. You'll meet them. You'll hear from them between reports, not only on them.

    One accountFix it once. Every other account gets the same guard — the rule travels, your data never does.
    1. 01

      Mandate

      You set the number before we spend the money.

    2. 02

      Meter

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

    3. 03

      Sweep

      Waste is found daily, named, and priced.

    4. 04

      Countersign

      Nothing reaches a live account with one name on it.The Refusal List lives here. An automated guard refuses to push an ad whose landing page contradicts what the ad group is bidding on — a control one of our team wrote after a real near-miss, not after a strategy day.

    5. 05

      Ledger

      Every executed change becomes a record you can open.

    6. 06

      Statement

      A fixed cadence, good news or bad.

    The carry

    Then the lesson carries into every other account.

    We catch a near-miss on one account and turn it into a pre-flight control on all of them. A strategist argues a rejection, writes down her reason, and we make it a standing rule. The next business in that trade starts pre-negated on day one, off a bank the team keeps by hand and the accounts before it paid for. These are files, written by people, with dates and reasons on them — it holds the rules we have written into it.

    Return on the same spend
    Month oneLinearCompoundingToday
    The same budget, managed two ways. A linear account returns what you put in. A compounding one returns what it has already learned — the gap widens with time. The shape is illustrative of compounding; it is not a measured result. Marked along the way: Day one, A rule is written, The rest inherit it.
    The short version

    Most agencies will tell you what they'd do. We'll show you the list of things we won't let ourselves do.

    What we run

    Full-Service
    Digital Marketing

    Five families, one team. Get found, get chosen, get paid — and know exactly which part of it did the work.

    The Refusal List

    So here is the list.

    Six things we have decided we will not let ourselves do — including when a client asks, including when it would be quicker. One of them has a date attached, and that one is underneath.

    • An ad whose landing page contradicts its ad group's intent.
    • A campaign switched on before the build has been read end to end.
    • A phone number written into ad text instead of a call asset.
    • A phrasing a platform has already rejected on another account.
    • A change pushed with one name on it.
    • A report held back because the month went badly.

    Incident · 2026-05-05 · closed

    We briefed a bond-cleaning ad group against a carpet-cleaning page.

    The brief mapped “Bond Cleaning” to the carpet-cleaning landing page, so the draft that came back pointed a bond-cleaning ad at the wrong service. One of us caught it at the countersign, before we had spent a dollar — which is the entire reason a second person reads these.

    Then we did the part most agencies skip: we wrote the check. Our publishing system now refuses to push an ad when the landing page contradicts what the ad group is bidding on, and it runs on every cleaning account we manage — including the ones that were never anywhere near this.

    What we redact

    The account. It did nothing wrong; we did. The industry is as specific as this gets.

    What we don't

    The decision. It is a file with a date and a reason in its header, and publishing your own near-miss takes a decision, not a budget.

    The full list sits inside SoudCoh Compound™, alongside the check itself — the actual source of the guard, printed on the page, because an excerpt you could paste into an editor is a different kind of claim from a paragraph saying we are careful.

    Read the Refusal List
    The SoudCoh Group

    One studio.
    Five divisions.

    Soudcoh started as a Melbourne marketing agency. We built the other four divisions because clients kept asking us to keep going — into their software, their public-sector work, their research and their civic creative. Same team, same standards, one point of contact.

    Who we do this for

    Your size changes
    the whole plan.

    A sole trader chasing next week's jobs and a national brand defending next year's market share both need advertising. Almost nothing else about the two programmes is the same — the channels, the reporting, the approvals, the speed.

    How to tell which one is yours

    Use who makes the decision, not what the company turns over.

    • One person decides the marketing budget, usually between jobsSmall business
    • There is a sales team, and an argument about lead qualityGrowing companies
    • A campaign needs sign-off from legal, brand and a division headEnterprise and government

    Sitting between two of them is normal. Pick the harder one — it is easier to simplify a programme than to retrofit governance onto one that never had it.

    The smallest companies we work with invest a minimum of A$3,000 a month in ad spend; our largest run multiple eight figures a month across paid channels. Management fees scale with the work, month to month. The first call is free and there is no deck.

    Compare all three
    Where we work

    Same method.
    Different levers.

    We work the same way on a plumbing account and a mortgage brokerage. What changes is what we already know about the auction you are bidding in — and how much of that we can hand you before you have paid for any of it.

    1. The negative-keyword bank you inherit on day one

      Plumbing, electrical and cleaning each have a negative-keyword bank our team maintains by hand, built from the accounts that came before yours. A new account in that trade starts pre-negated — you are not paying to learn what we already know, and the money that would have gone on the DIY searches never leaves your budget.

    2. Structured by job, not by trade

      End-of-lease, bond-back and emergency are three different searches with different intent and different price sensitivity, and one generic cleaning campaign hides all of it in the noise. We separate them at a level of detail most accounts never reach, so the keyword, the ad and the page all say the same thing, which is most of what Quality Score is actually measuring.

    3. Bidding that follows the industry's weather

      Roofing demand arrives in storms. Cornerstone Roofing's account is built to move with that weather rather than sit flat through it, and returned 68 quote requests in 35 days. A trade with steady, year-round demand is built differently — the structure is chosen for the shape of the demand, not applied by default.

    4. Copy written to the rules your industry is bound by

      For mortgage and finance brokers, every ad and landing page is reviewed against ASIC, NCCP and ACL guidelines before it goes live. Generic agencies routinely get finance accounts disapproved or suspended, and a disapproved finance account is a licence problem rather than a marketing one. We write to the rules.

    Ten industries have a page of their own.

    Each one is the strategy, the objections and the real client numbers for that trade — written because those questions come up often enough to be worth answering once, properly.

    We run programmes across 30+ verticals. If yours is not one of the ten, that is not a problem — those ten have pages because they ask the same questions often enough to be worth writing down, not because the others are out of scope.

    Our process

    How We Work

    Four stages, run by a team you'll know by name — from the first conversation to the standing session where we decide what to scale next.

    Stage 01

    Discovery

    We sit down and learn the business properly — what you sell, who buys it, what a good customer is worth to you, and where you actually want to be in a year. Not a form. A conversation, with the people who'll be doing the work in the room.

    Stage 02

    Strategy

    Our analysts and media buyers go through your numbers together and come back with a plan you can read: which channels, in what order, what we expect each one to do, and what we'd stop doing. You get to push back before anything is built.

    Stage 03

    Execute

    We build it — search, social, the website, the tracking — a second person checks it, and then it goes live. From there we are hands-on: we read the data every day and make the small calls that add up, week after week.

    Stage 04

    Report & Scale

    We report on a fixed cadence, in plain English, good news or bad — then we sit down with you and decide together what to double down on and what to cut. That loop is the whole job.

    Recent work

    Six engagements.
    Six records.

    Not all of it is advertising. The same team writes the software, runs the research and makes the printed things — so here is one piece of evidence for each part of that claim, with the record behind it a click away.

    Public-sector and cultural clients are shown by sector and jurisdiction only. That is a standing policy rather than a gap in the record — those organisations are named to us and to their own boards, and nowhere on this site. The figures are unchanged either way, and each one links to the division that holds the full write-up.
