Hiring a marketing agency is a strange purchase: you’re buying expertise precisely because you don’t have it, which means you’re least equipped to judge quality at exactly the moment you’re choosing it. Every agency deck looks competent, every portfolio glows, and the real differences (who’ll actually do the work, what happens when results lag, who owns your accounts when it ends) only surface months and millions of naira later.

This guide fixes the information asymmetry: the preparation that makes you hard to fool, the seven questions that expose everything in one meeting, and the red flags that end meetings early. And a disclosure that is also the point: we are a marketing agency. Use every question below on us. An agency that squirms under its own buying guide has told you what you needed to know, whichever agency it is. (If you’re still deciding between an agency and hiring in-house, that’s a different question with its own guide; this one assumes you’ve decided to buy and now must choose well.)

Before any meeting: the two-page homework that changes the power balance

Agencies write proposals to fill vacuums. Arrive with the vacuum already filled: your baseline numbers and customer economics on one page, and a written goal, the outcome you want, with a number and a date, on the other (the first two parts of the working marketing plan). This does three jobs at once: it forces every proposal to address your goal instead of the agency’s favourite services; it makes proposals comparable, because they’re all bidding on the same outcome; and it instantly sorts the room, agencies that light up at a client with a written goal are the ones built for accountability, and agencies that go vague are showing you the next twelve months in miniature.

The seven questions (and what the answers mean)

1. “What will success look like in writing, and by when?” The only acceptable answer is a specific, staged goal — leading indicators early, business numbers later, like the SEO timeline’s staged structure. Refusal to commit to anything written is the meeting’s first exit ramp. (The opposite failure matters equally: anyone guaranteeing rankings or results is lying about a system nobody controls, the oldest lie in the industry.)
2. “What happens if you miss?” This is our own accountability framework offered as an industry standard, and any agency can be held to it: a written consequence, remediation at their cost, fee reduction, easy exit, borne by the vendor. The answer reveals whether their confidence is priced in or just printed on the deck.
3. “Who owns every account, and can we walk with everything?” Ad accounts, analytics, the website, content, data, created in your names, admin access yours from day one, exportable on exit. The commonest Nigerian horror story isn’t bad marketing; it’s the hostage situation discovered at breakup. Any hesitation here ends the meeting.
4. “Who, by name, will work on our account?” The pitch team and the delivery team are often different people. Ask who does the actual work, how senior, across how many other clients, and whether the work is done in-house or quietly subcontracted. You’re hiring humans, not a logo.
5. “Walk me through how you’d diagnose us before prescribing.” A serious agency’s first move is an audit, your numbers, your funnel, your market, because the leak dictates the priority. A proposal with services and prices attached before any diagnosis is a menu, not a strategy, and it tells you the same services get sold to everyone.
6. “How will we see what’s working, in our own systems?” Reporting should reconcile to revenue in measurement you control, not platform-flattered dashboards. Agencies grading their own homework produce suspiciously good grades: ask what a monthly report contains, and whether they’ll ever recommend reducing spend. (“Yes, and here’s when we last did” is the best answer in this entire list.)
7. “How do we leave?” Notice periods, handover obligations, what happens to work in progress. Reasonable answer: 30-60 days and a documented handover. Long lock-ins with penalties are an agency pricing its own expected disappointment.

The pattern behind all seven: you are not buying marketing services; you are buying an operating relationship, goals, ownership, transparency, exits. Services can be judged in a portfolio. Relationships can only be judged by the terms someone offers before they have your money. The questions simply make the terms visible early, while your leverage is at its maximum and theirs is at its minimum.

Red flags that end meetings (a short, non-negotiable list)

Guaranteed rankings, guaranteed results, or guaranteed AI citations. Accounts or hosting held in the agency’s name “for convenience.” Reports that count activities (posts made, ads launched) instead of outcomes. A quote covering “everything” at a price that couldn’t cover anything done properly, a ₦150k retainer promising SEO, ads, social, and content is either dishonest or distributed across so many clients that you’re buying minutes. Pressure to sign long lock-ins at the first meeting. And name-dropped clients you’re not permitted to call. Any two of these together isn’t a negotiation point; it’s the answer.

In conclusion

Choosing an agency well is mostly refusing to be the easier version of yourself: arrive with a baseline and a written goal, ask the seven questions that surface the operating terms, insist on owning everything with an exit you could actually use, and let the red flags do their merciful work early. A good agency will pass this screen with visible relief, accountable shops are desperate for clients who measure, and a bad one will disqualify itself in under an hour, which is the cheapest bad-agency experience available. We publish this knowing we’ll sit across the table from readers holding it. That’s the intention. Bring the list.
