    Choosing a Marketing Agency: Five Questions That Filter

    By the time a company starts choosing a marketing agency, it has usually met three to five of them and received proposals that read alike: exposure promises, content operations, industry experience. What actually separates them is detail — how the budget is split, how success is defined, and what happens when the numbers do not move.

    1. Know Which of Three Types You Need

    TypeDeliversChargesFits
    Channel specialistAccount setup and ad optimisationFee plus spendYou have assets, need volume
    Content teamTopics, articles, videoProject or retainerYou lack content assets
    Full serviceStrategy, content, ads, siteRetainer or annualBuilding from zero

    None is inherently better, but mixing them up causes mismatch. A channel specialist does not own content. A content team does not guarantee media performance. Full service costs more and coordinates definitions across functions. Decide which gap you have before you start meeting vendors.

    2. Five Questions

    If I halve the budget, what do you cut first and why? The answer reveals whether they understand priority.

    What exactly will you deliver this month, and where can I see it? Vendors who cannot name deliverables work on impressions.

    When results are poor, how do you tell whether it is the channel or the creative? This filters out report-only suppliers.

    Who owns the accounts, assets and data? A professional answer is: the client does.

    Why did your last client end the engagement? Willingness to explain signals a review habit.

    3. Comparing Quotes Fairly

    Write one brief both vendors work from: goal, period, channels, content volume, delivery frequency, metric definitions. Six items aligned makes prices comparable.

    Watch for three asymmetries. Ad spend rolled into the service fee, so the total looks low while the unit cost is high. Vague content volume where "several articles monthly" becomes two. And site or landing page work excluded, billed separately once campaigns start.

    Much of the difference between agencies sits in quote transparency. Teams that separate fee from spend and fix content volume in writing tend to argue less during execution.

    4. Three Checkpoints After Kickoff

    Month one: responsiveness. How fast do requests get a schedule, how fast do issues get an answer. Month two: delivery quality. Is content following the agreed topic bank, is there an optimisation log. Month three: definitions. Does the report go beyond impressions and clicks to conversion and cost.

    Three months is a fair window. If by then nobody can explain where the money went and what it produced, change the arrangement rather than increasing budget.

    5. Signals of Reliability

    Three things: a contract that states service boundaries and exit terms; direct access to the person doing the work rather than only the sales contact; and willingness to run a baseline audit before starting, covering existing data, competitor landscape and keyword structure.

    The baseline audit is the clearest signal. Agencies that skip it and hand over a renamed version of the last client's plan are easy to spot.

    6. FAQ

    Do we have to sign annually? No. Start with three months on one metric set, then decide whether to extend.

    Quotes differ by three times — is that normal? Yes, usually content volume and staffing. Ask for itemised pricing and compare line by line.

    How do we know the data is real? Request read-only access to the ad and analytics accounts and read the raw numbers yourself, alongside the agency's definitions.
