The Short Answer

The most revealing questions cover four areas: their process (how they define qualified leads and what the first 30 days look like), their accountability (how they report and what happens when results disappoint), their understanding of your business (what makes your buyers different and what your close rate currently is), and their proof (specific clients in your industry you can contact independently). Good answers are specific and committing. Vague answers are the answer.

Why These Questions Work

Vague questions produce vague answers that are designed to reassure. Specific questions that require committing answers put an agency in a position where they have to either demonstrate real substance, or reveal the absence of it.

The goal isn't to trip anyone up. It's to gather the information that helps you make a good decision, rather than leaving that decision up to whoever gave the most polished sales presentation.

Questions About Their Process

1

How do you define a qualified lead for a business like mine, before any campaign launches?

Vague answer"We'll target your ideal customer profile based on your input." No specifics. No written criteria. No commitment.
Good answer"We document lead qualification criteria, budget, role, intent signal, in writing before any campaign launches, and report against them monthly."
2

What does the first 30 days look like before any campaigns are running?

Vague answer"We'll get onboarded and launch as quickly as possible to start generating results." Campaigns in week one.
Good answerA named, structured onboarding process: ICP definition, messaging workshop, competitive review, platform setup. No campaigns until the foundation is right.
3

Who specifically will manage my account day-to-day, and can I meet them before I sign?

Vague answer"You'll work with our team." No name. You meet them after you sign. May be a junior with no context on your business.
Good answerA specific name, their background and experience, and willingness to schedule a call with them before any contract is signed.

Questions About Accountability

4

What does your monthly reporting include beyond cost per lead and impressions?

Vague answer"We provide a full monthly performance report with all key metrics." Ask what "all key metrics" means. If it's CPL and CTR, that's telling.
Good answerReporting that includes qualified lead volume, lead-to-sale conversion rate where trackable, cost per acquired customer, and pipeline value generated.
5

What happens if the leads you generate aren't closing at a rate that makes the investment worthwhile?

Vague answer"We generate the leads, closing is on your sales team." This is the most common deflection in the industry. It's a red flag every time.
Good answer"We examine targeting, messaging, and creative. Lead quality is our accountability. If the close rate is low, we look at what we're sending before we look at how it's being received."
6

What are your contract terms, and what does exiting look like if the relationship isn't working?

Vague answerA 6–12 month contract with no performance clauses and a complicated exit process. Protects the agency, not you.
Good answerMonth-to-month or a short pilot option. Clear notice period. An agency confident in their work doesn't need a long lock-in before demonstrating results.
7

Tell me about a campaign that didn't work as expected, what happened and what did you do?

Vague answerA vague answer, a pivot to a success story, or visible discomfort. Agencies with nothing to hide talk honestly about failure.
Good answerA specific story: what the campaign was, why results were poor, what they diagnosed, what they changed, and what the outcome was. Honest and detailed.

Questions About Your Specific Business

8

What's different about the buyers of a business like mine compared to others you've worked with?

Vague answer"Every business is unique, and we tailor our approach accordingly." Says nothing. Could apply to any client conversation.
Good answerSpecific observations about the trust requirements, decision timeline, or buyer psychology that applies to your industry. Shows they've thought about this before the call.
9

What's your honest assessment of whether we're ready to run paid lead generation right now?

Vague answer"Absolutely, we'd love to get started." No pushback. No questions. An agency that never turns down a client isn't doing strategy, they're selling a product.
Good answerA genuine assessment: "Before we run ads, here's what I'd want to review..." Or if there are concerns, naming them directly, even if it means recommending a different starting point.
10

What does your sales team's current close rate look like with your best leads vs average leads?

Why this question mattersIf an agency never asks about your existing sales performance, they're not in a position to build a system that feeds it intelligently. This question tests whether they're thinking about your whole pipeline or just the top of it.

Questions About Their Proof

11

Can I speak with a current client in a similar industry to mine, independently, not a reference you arrange?

Vague answerHesitation, managed references only, or "we'd need to check with them first." Hand-picked references tell you very little.
Good answer"Yes, here are two clients in your sector. Reach out to them directly." Confidence that the typical experience matches the sales story.
12

What's your most honest answer to: why should I trust that this will be different from my last agency?

Vague answer"We're different because we really care about results." Every agency says this. It answers nothing.
Good answerA specific, structural answer: named differences in how they're set up, what commitments they make in writing, what the accountability mechanism looks like. Demonstrated, not claimed.

How to Evaluate What You Hear

Reading the answers

Good answers are specific and committing, they name a person, a number, a written commitment, or a specific process. If you could hold the answer accountable later, it's a good answer.
Vague answers are designed to reassure without committing. "We tailor everything to your business" and "results are our priority" are not answers, they're positioning.
Deflective answers pivot away from the question. If you ask about what happens when results disappoint and the answer immediately goes to your sales team, that's deflection worth noting.
The best agencies will ask you as many hard questions as you ask them. Thoroughness in their sales process usually predicts thoroughness in their work.

Common Questions

What questions should I ask a marketing agency before hiring them?

Cover four areas: their process (how they define qualified leads, first 30 days structure, who manages your account), their accountability (reporting framework, what happens when results disappoint, contract terms), their understanding of your business, and their proof (current clients you can contact independently).

How do I evaluate a marketing agency's answers to my questions?

Good answers are specific and committing, they name a person, a number, a written commitment, or a specific process. Bad answers are vague, deflective, or designed to reassure without committing. If an agency gives a confident general answer to a question that deserves a specific one, that is the answer.

What should I ask about contract terms before hiring a marketing agency?

Ask what the minimum commitment period is, what happens if results don't materialise in the first 60 days, whether you can exit with reasonable notice, and whether there's a performance clause. A confident agency won't need a long lock-in. If the contract terms are more elaborate than the results commitment, pay attention to that imbalance.

Is it normal for a marketing agency to ask me lots of questions before proposing?

Yes, and it's a very good sign. An agency that jumps straight to proposing without understanding your business, your buyers, and your previous results isn't in a position to make good recommendations. The agencies that ask the most questions before pitching are typically the ones most likely to deliver relevant work.
