How to choose a marketing agency: 9 questions that reveal everything

Choosing a marketing agency is one of the few purchases where the thing you are buying does not exist yet. You are buying a promise about future work, from people who are professionally good at making promises sound credible. Case studies show wins and quietly omit the accounts that went nowhere. Everyone claims to be data-driven. Everyone shows a dashboard.

The way through is not a better brief. It is a better set of questions — ones where a vague answer is itself the answer.

Why the pitch tells you so little

A pitch is a performance of competence, and the people performing it are frequently not the people who will do the work. That is not always dishonest; senior staff sell, junior staff deliver, and that is normal across professional services. It only becomes a problem when nobody tells you, and the gap between the pitch team and the delivery team is where most disappointing engagements are born.

So the questions below are built to surface structure rather than talent. Talent is hard to assess in a meeting. Structure — who is accountable, what is contractual, how work actually moves — is not.

The nine questions

1. Who specifically will work on our account, and what else are they on?

You want names, roles and a rough sense of load. An agency that answers instantly, with names, is telling you the team already exists. An agency that says “we will assign the right people once we are underway” is telling you they will hire or sub-contract after you sign.

2. Can I see a real weekly report from a live account, with the client redacted?

This is the single most revealing question in the list. If reporting is automated and routine, someone can pull one up in under a minute. If it takes a week, reporting is a manual scramble that happens only when a client asks — which means you will be the one asking, every month, forever.

3. What would you tell us not to spend money on?

Every business has a channel or an activity that is not worth it for them right now. An agency that has actually looked at your situation will have a specific answer. An agency that says “it depends” or tries to sell you everything has not looked, or does not want to shrink the scope.

4. Who owns the ad accounts, the analytics, the domain and the creative files?

The correct answer is: you do, from day one, in your own accounts, with the agency granted named access. Anything else — accounts held in the agency’s business manager, domains registered to them, working files withheld — converts a service relationship into a hostage situation the day you want to leave.

5. What does the first 30 days look like, day by day?

Good agencies have a repeatable onboarding because they have done it many times. Ask for the sequence. Vague answers here usually mean the first month will be spent working out what the first month is.

6. How is the fee structured, and what is excluded?

You are looking for the boundary. Is media budget inside or outside the fee? Who pays for stock, licences, hosting? How many revision rounds are included before it becomes a change order? Percentage-of-ad-spend models are not automatically bad, but they do mean your agency earns more when you spend more, which is worth naming out loud.

7. What is your notice period, and what happens at offboarding?

A 30-day notice period costs a confident agency almost nothing. Long lock-ins exist to protect agencies from clients leaving, which tells you what they expect. Ask specifically what you receive at offboarding: files, credentials, documentation, and how quickly.

8. Have you worked with a direct competitor of ours?

The answer itself matters less than the willingness to answer. You want to hear disclosure and a clear position — either they decline conflicting work, or they will agree exclusivity in writing for your category and territory.

9. What would make you fire us as a client?

An agency with a real point of view has boundaries: unrealistic timelines, refusal to give account access, asking for claims they cannot substantiate. An agency that says “nothing, we work with everyone” is telling you they will take any brief, including the ones that fail.

What a good answer sounds like

Good answers are specific, and they usually contain something slightly unflattering. “You will get Priya as your account lead; she is on three other accounts, so Tuesdays and Thursdays are your days” is a better answer than “you will have a dedicated team”. The first can be checked. The second cannot.

The same test applies to results. A specific outcome with its context — category, budget range, timeframe, what did not work — is worth more than a large number with no denominator.

Red flags worth walking away from

• Guaranteed rankings, guaranteed leads, or any promise of a specific commercial result. Nobody controls the auction or the algorithm.
• Reluctance to put ownership of accounts and creative in the contract.
• A pitch team you never meet again after signing.
• Reporting that only appears when you ask for it.
• Pressure to decide inside a deadline that exists only because they set it.

How to run the comparison

Send the same nine questions to every agency on your shortlist, in writing, and ask for written answers before the meeting. This does three useful things: it makes the answers comparable, it removes the advantage held by whoever presents best, and it shows you how each agency communicates when nobody is performing.

Then score them on structure, not charm. The agency that answered plainly, disclosed a conflict, told you what not to spend money on and agreed to a 30-day exit is the one that expects to keep you by being useful.

The agency that is easiest to leave is usually the one you will stay with longest.
