Buying digital marketing in a mid-sized market works differently from buying it in a large one. There are fewer firms, most of them know each other, and reputation travels. That is an advantage if you use it, because references here are checkable in a way they are not in a market with hundreds of options.
The digital marketing supplier pool in Brisbane is small enough to check properly
Before you shortlist anything, spend an afternoon on references rather than on websites. Ask each candidate for two clients in roughly your industry and roughly your budget band, including one that has since left. The departed client is the useful call. Ask what the working rhythm was really like, how long approvals took, whether the senior person stayed involved after the first quarter, and what the handover looked like at the end.
The other thing a small pool gives you is honest conflict information. Ask directly whether the agency works with a competitor and how it separates the teams. In a larger market you would be told there is a policy. Here you can usually find out the truth from somebody else in the industry within a week.
Buy a paid pilot before you buy a year
Annual digital marketing retainers are the default offer here and they suit the supplier more than they suit you at the start. A better first step is a short paid engagement with a defined output: an audit of the existing digital marketing accounts, a channel plan with a budget split, and one campaign built and launched. You learn how the team writes, how it argues, how fast it moves and whether the person who pitched is actually involved.
Price the pilot properly rather than asking for it free. Free work is done by whoever is available, which is rarely the person you want. Paid work gets the team you would get on a retainer, which is the whole point of the exercise.
Ask what happens when the person who knows your account leaves
Smaller digital marketing agencies concentrate knowledge in individuals. Your account is often genuinely run by one strategist and one buyer, and their departure is the largest single risk in the arrangement. It is not a reason to avoid smaller firms, which frequently give you far better attention than you would get elsewhere. It is a reason to insist on documentation as a deliverable.
What you want in writing is the account structure and why it is built that way, campaign naming conventions, the audience definitions and where they came from, the creative testing history with results, and current access lists. Ask for it quarterly, not at the end. An agency that cannot produce this without a fuss is telling you the knowledge lives in one head.
Channel mix in a market where referral still does heavy lifting
A lot of business here still arrives through relationships, trade networks and repeat customers, and companies with that history tend to buy digital marketing as a top-up rather than as a system. The mistake that follows is spending the entire budget on capturing demand that already exists, which works until the existing demand is exhausted and then stops working without any obvious warning.
Ask each candidate to propose a split across three jobs: capturing people already searching, reaching people who do not yet know you exist, and keeping the customers you have. Then ask what evidence would make them shift the split. The answer tells you whether you are buying a media buyer or a marketer. Both are legitimate purchases, but only one of them will tell you when the plan needs to change.
Fee, media and the numbers that are not the agency's to claim
Require the digital marketing fee and the working media budget to be quoted as separate lines, with the fee described as named roles and their time. Then ask whether media is passed through at cost and whether any platform incentives or volume arrangements exist. Put the answer in the contract.
Separately, agree what counts as a result. Platform reporting will credit conversions generously, and in a business with a phone-heavy sales process the platform simply cannot see most of what happens. Decide early whether the score is enquiries qualified by your sales team, booked jobs, or revenue, and accept that the honest number will be smaller and later than the dashboard number. Ownership follows the same logic: advertising accounts, analytics, tag containers and audience lists sit in entities you control, with access granted to the agency.
The calendar your campaigns actually run against
Buying patterns in this market do not line up neatly with the imported templates most planning tools assume, and the warm months at the turn of the year are a quiet trading period for a lot of categories while being the busiest for others. Any agency worth hiring will ask you for two or three years of your own sales data before proposing a flighting plan, and will treat weather, school terms and trade events as real inputs rather than as colour. If a candidate presents a calendar without asking for your numbers, they are presenting a template.
Three references, one brief, one decision
Two or three candidates, the same written brief, the fee and media split out, and a paid pilot for the finalist is enough process for almost any company at this scale. Anything longer costs you a quarter of trading. If you would rather write the requirement once and receive proposals in a consistent shape, set out the brief and collect comparable offers.
Where the constraint is one discipline rather than the whole mix, compare the generalist against firms that work only on organic search, and look at studios that produce motion and video if creative volume rather than media management is what you are short of. Larger benches and deeper specialisms sit in the bigger southern capital markets if your requirement outgrows the local pool. The overview of digital marketing agencies explains what the category usually includes.
