    Google Display advertising agency, Melbourne Display is the reminder, not the ask.

    Most buying decisions are made away from Google, over days, while somebody thinks about it. Display is how you stay in the room for that — on the sites and apps they use in between. Done properly it is cheap presence. Done carelessly it is the easiest money to waste in the whole account.

    Seven ways a
    Display budget leaks.

    Display is the channel where nothing looks broken. Impressions are enormous, clicks are cheap, and the report reads fine right up until you ask what any of it produced.

    • The budget quietly moves into games

      Mobile app inventory is on by default. Left alone, a real share of the money goes to accidental taps inside puzzle games and torch apps, and the click report looks busy while the phone stays quiet.

    • Optimised targeting spending outside your list

      Google switches on the setting that lets it look beyond the audience you chose, and nobody reads it. Then your remarketing campaign is no longer a remarketing campaign.

    • No frequency cap

      The same person sees the same banner forty times in a week. That is not a reminder any more, and the people it annoys most are the ones closest to buying.

    • One image, cropped by a machine

      Google needs a landscape image and a square one. Upload only the landscape and it crops the square itself — heads cut off, logos squashed, the price tag outside the frame.

    • Judged on the click, then switched off

      Display click-through rates are a fraction of Search's and always will be. If nobody separated view-through from click-through before launch, the campaign gets killed for doing exactly the job it was bought to do.

    • Buyers still being followed after they bought

      No exclusion list, so the remarketing audience keeps serving to people who already enquired, already paid, or already got the job done. You are paying to advertise to your own customer list.

    • The placement report never opened

      It lists every site, app and channel your money actually landed on. It is the Display equivalent of the search terms report, and in most accounts we take over nobody has read it.

    The ad, actual size

    You do not design the banner. You supply the parts.

    A responsive display ad is not one artwork. It is a kit of images, logos and text that Google reassembles to fit whatever slot it wins — a strip on a news site, a square in an app, a card in Gmail. Whatever you leave out is simply missing from the ad.

    • 30

      characters per headline

      Five of them, and Google shows them in combinations you did not choose. Each one has to stand alone.

    • 90

      characters, long headline

      The one slot with room for a full sentence. On large placements it is the first thing read.

    • 15

      images per ad

      The ceiling. Fill it and the machine has real choices to test; give it three and it tests three.

    • 1.91:1

      and 1:1 — both required

      Landscape and square. Supply both or Google crops one from the other, badly, at the worst moment.

    • 5

      logos, square and wide

      1:1 and 4:1. The wide one is the slot most accounts leave empty, so the ad shows a letterbox.

    • 25

      characters, business name

      It appears on nearly every placement. A trading name that overflows is truncated without warning.

    So we build for the crop, not for the mockup.

    Every image is supplied in both required ratios, framed so the subject survives the square. Logos go in wide as well as square, because the wide slot is the one most accounts leave empty and an empty slot is a letterbox where your name should be. Text is written so any headline can sit above any description without reading like a mistake.

    Then we look at what Google actually assembled and served, which is rarely the combination anyone pictured. That check is the difference between uploading fifteen images and knowing which two are carrying the campaign.

    Whole-account figures from live client Google Ads accounts, each written up as a case study. They are what those accounts did, in those markets, at those budgets — not a forecast for yours, and not attributed to any single campaign type.

    Ten things happen on a Display account. Here they are, in order.

    Almost all of it is subtraction — deciding where your money is not allowed to go. That is the part most agency pages leave out, and it is the part that decides whether the channel is cheap presence or an expensive rounding error.

    1. Decide what Display is for on this account

      Reminding people who already came, or reaching people who have not heard of you. They need different audiences, different creative and different measures of success, and running them in one campaign hides both.

    2. Exclude the inventory nobody meant to buy

      Mobile app categories, parked domains, and the content types you would not want your name beside. This happens before launch, not after the first report shows where the money went.

    3. Build the audience from behaviour, not guesswork

      Your own visitor lists split by what they looked at, custom segments built from the searches your customers actually make, and in-market segments for people already shopping. Interests come last, if at all.

    4. Turn off the settings that spend outside your targeting

      Google enables optimised targeting by default and it reaches beyond the audience you picked. On a remarketing campaign that defeats the point. We switch it off, then bring it back deliberately if there is a reason to.

    5. Produce the whole asset set, at every crop

      Both image ratios, both logo shapes, five headlines, the long headline, five descriptions, the business name inside 25 characters. A half-filled asset set is a half-sized ad on most placements.

    6. Cap the frequency and set a recency window

      A ceiling on how often one person sees you in a day and a week, and a rule that stops showing the ad once someone is past the point where it helps. Reminding is useful. Following people is not.

    7. Exclude the people who already said yes

      Converters, existing customers, and for online stores everyone who has already bought — so the cart-abandonment ad talks only to the carts that were actually abandoned. This is a list, and it needs maintaining.

    8. Separate view-through from click-through before launch

      Someone who saw the banner on Tuesday and searched your name on Friday is a real outcome, but it is not a click. Put the two in one column and you cannot tell what Display did, so we split them from day one.

    9. Prune the placement report every week

      We open the list of sites, apps and channels your ads actually ran on, exclude the waste, and give the placements producing enquiries their own campaign. It is the least glamorous job on a Display account and the biggest lever on cost.

    10. Move the bidding once there is something to bid on

      We bid on impressions while a campaign is only being seen, then move to conversion-based bidding once there are real actions to aim at. We follow the budget to whichever audience is producing, and the rest gets cut.

    How an engagement runs

    The first ninety days, honestly.

    1. Week 0

      The audit and the first call

      What you sell, who buys it, how long they take to decide, and what a customer is worth. Then we open the account and read the placement report and the audience lists — usually the first time anyone has.

    2. Week 1

      Assets and exclusions

      Both image crops, both logo shapes, the full text set, the exclusion lists, the frequency cap and the audience build. A real test enquiry is pushed through every call and form path. Nothing is live and nothing has spent.

    3. Day one

      You press go

      We build every campaign paused so you can read the whole thing first, including every placement category we have excluded. You switch it on when you are ready, not when we are.

    4. Days 1–14

      The prune

      The placement report read every few days and cut hard. Bad inventory excluded, weak images swapped, frequency adjusted against what the data says people are actually seeing.

    5. Weeks 3–6

      The picture arrives

      Enough view-through and assisted-conversion data to see which audiences are worth the money. Remarketing usually separates from prospecting here, and they stop sharing a budget.

    6. From there

      Rhythm

      Weekly placement pruning and creative refreshes before fatigue sets in, reporting on a fixed cadence whether the news is good or bad, and a proper conversation each quarter about the next block of budget.

    We build every campaign paused, every time. You read the build — including every placement category we have excluded — before a dollar moves. That is a rule we hold ourselves to, not a favour.

    Where this sits in SoudCoh Compound

    The two levers Display leans on most.

    Display is easy to buy and easy to misjudge. With view-through kept apart from clicks, every placement and audience is held to your cost-per-lead line, and the budget follows the ones that clear it.

    • Rung 4

      Threshold Refresh

      The number it moves: Cost per lead

      The placement report is read every week: sites, apps and images that spend above your cost-per-lead line are excluded or swapped, and the money stays with the placements that book.

      How Threshold Refresh works
    • Rung 5

      Scale on Proof

      The number it moves: Enquiries vs spend growth

      A placement or audience that keeps producing enquiries gets its own campaign and budget, and remarketing stops sharing a budget with prospecting once one of them is clearly booking.

    The first call is free and there is no deck.

    Talk to us about your account

    Two separate numbers. Your ad spend goes to Google, and Display impressions are bought far more cheaply than Search clicks — which is exactly why it is easy to waste money on them quietly. We recommend a minimum of A$5,000 a month across paid channels for most businesses, and the largest companies we work with currently invest up to A$30,000 a day in advertising. 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 get a real number for your situation before you commit to anything.

    Impressions and clicks arrive immediately; the useful signal takes longer. The first two weeks are placement pruning — cutting the sites and apps that spend without producing. Real read-outs on view-through and assisted conversions usually need four to six weeks, because Display's job is to be present during a decision rather than to close it. If your customers decide in an afternoon, Display matters less; if they take a month, it matters a lot.

    No long-term lock-in. We would rather keep the work because it is producing than because a contract says you have to stay. What we do ask for is enough runway to be fair to the channel — a Display campaign judged on its first ten days is being judged during the fortnight we spend cutting waste out of it. The terms are put in front of you in plain English before anything is signed.

    We own and run the account, because the build is proprietary methodology refined across 250+ engagements — audience stacks, exclusion lists, creative systems and conversion tracking. You get full-visibility reporting on performance and spend at all times, and on long-term marketing agreements ownership and handover options are available to discuss. You will never be in the dark about what is in the account or what it is doing.

    We tell you, in the report, in plain English, and we change what we are doing. A Display campaign that is not producing gets repointed at a tighter audience, rebuilt with different creative, or stopped and the budget moved to the channel that is working. If the honest answer is that Display is not the right buy for your business right now, we would rather say so than keep billing you for it.

    We report on a fixed cadence, good news or bad. Every report says what you spent, what it produced, what we changed and why, and what we are doing next — with view-through kept in its own column so nothing is flattered by being counted twice. The placement changes we made are listed, not summarised. You can also see live performance and spend for yourself at any time.

    Across Google's network of partner websites, apps, Gmail and YouTube — a very large pool, which is a strength and a risk in equal measure. We manage it with exclusions rather than optimism: mobile app categories switched off, content types you would not want your name beside removed, and specific placements added to the block list every week off the back of the placement report. You can also go the other way and hand-pick the sites you want, which we do for brands where the neighbourhood matters more than the reach.

    Sometimes directly, more often indirectly. Remarketing to people who already visited your site converts genuinely well and is where most of the direct leads come from. Prospecting to cold audiences rarely produces an enquiry on the spot — it produces the recognition that makes your Search ad the one they click a week later. That is why we measure view-through and assisted conversions separately, and why we would not usually run Display as the only channel in an account.

    We build responsive display ads, which means supplying the full asset set rather than a fixed banner: up to 15 images in both required crops — 1.91:1 landscape and 1:1 square — up to 5 logos in square and wide, five 30-character headlines, one 90-character long headline, five 90-character descriptions and a business name inside 25 characters. Google assembles those into whatever shape the placement needs. Where a brand needs exact control over a specific slot we also produce fixed-size banners, but the responsive set does most of the work.

    Four things, kept apart. Click-through conversions, which are usually the smallest number. View-through conversions, from people who saw the ad and came back later. Assisted conversions, where Display was one step in a path that ended somewhere else. And the plain sanity check — what happened to branded search volume and direct traffic while the campaign was running. Judging Display on last-click alone will always make it look worse than it is, and judging it on impressions will always make it look better.

    We tighten the content suitability settings rather than leaving them at the default, exclude the sensitive content categories, switch mobile app inventory off unless you have a reason for it, and keep a block list that grows every week, because someone here reads the placement report. If your brand needs harder control than that, we run managed placements — you choose the sites, and the ads appear nowhere else.

    Yes, and cart remarketing is usually where it earns its place first. A dynamic remarketing campaign fed by your product feed shows people the exact items they looked at, with the price, which is a very different ad from a generic banner. It runs alongside Shopping and Search rather than instead of them, and it needs an exclusion list so people who have already bought stop seeing it.

    Further reading

    Display rewards discipline more than it rewards ideas: the routine checks worth automating is the closest thing to a safety net a broad network has, and the mis-fired tag that inflates the numbers you judge it on explains most view-through figures that look too good.
