How to Choose a Marketing Agency: 7 Questions Every Small Business Should Ask

Most agency pitches are impressive. The deck is polished. The case studies are carefully chosen. The team in the room is senior, attentive, and full of ideas.

Three months in, the account manager is someone you’ve never met, the ideas haven’t landed, and you’re not sure what you’re actually getting for the retainer.

Knowing how to choose a marketing agency is one of the most valuable skills a small business owner can develop – because the cost of getting it wrong is not just the fee. It’s the six or twelve months of momentum you lose while the relationship disappoints.

After 20 years working with and alongside marketing agencies across global corporations and growing businesses in the North East, here are the seven questions that cut through the pitch.

1. Who will actually be doing the work?

In every agency pitch, the most senior people in the room present the work. Once you sign, they hand you to a more junior team.

Ask directly: who specifically will manage my account day-to-day? What is their experience? Can I meet them before we sign?

If the answer is evasive, or the person you meet in the pitch won’t be your main point of contact, that is important information.

2. Have you worked with businesses like mine?

Not just “similar sectors” – similar size, similar stage, similar marketing maturity.

An agency that works primarily with large B2C brands may not be the right fit for a 15-person professional services firm. The channels, the buyer journey, the content requirements, and the pace of decision-making are fundamentally different.

Ask for case studies from businesses at your size and stage – not their most impressive client logos.

3. What will you measure, and how often will you report?

Before you sign anything, agree on what success looks like. Not in vague terms – “increase brand awareness” – but in specific, measurable outcomes. Leads generated. Conversion rate. Traffic from target keywords. Revenue influenced.

Ask how frequently you’ll receive reporting, in what format, and what happens when results are below target. The answer tells you a lot about how the agency thinks about accountability.

4. What do you need from me to succeed?

A good agency will be honest about what they need from you: time, access to information, approval processes that move quickly, content from the business.

An agency that says they need very little is either wrong about the work or not planning to involve you appropriately. Both are problems.

Understanding your own capacity before you engage is important. If you’re a founder without a dedicated marketing resource, factor that in – because some agency models require significantly more client involvement than others.

5. What would you not do for a business like mine?

This is a question most people don’t ask, and the answers are often the most revealing.

A good agency will be honest about what they’re not the right fit for. They’ll tell you which channels they don’t think will work for your audience, which approaches they wouldn’t recommend at your budget, and what mistakes they’ve seen businesses like yours make.

An agency that says they can do everything equally well for every kind of business is telling you something important – just not something useful.

6. What does the first 90 days look like?

Strategy, setup, and early execution should look different from month four onwards. Understanding what the agency will actually do in the first three months – and what they expect to be able to show for it – is essential for managing expectations and evaluating progress.

Be wary of agencies that can’t give you a clear picture of the first 90 days. Vagueness at the pitch stage usually means vagueness in delivery.

7. What’s the exit?

This is uncomfortable to ask, but important to know.

If the relationship isn’t working after six months, what happens? What do you own – the website, the content, the ad account, the strategy documents? What notice period applies?

Agencies that build in dependency – where you can’t take the work elsewhere without losing everything – are worth approaching with caution. Agencies that are confident in their value are usually comfortable with reasonable exit terms.

And before you bring any agency in, it’s worth being honest about whether your marketing foundations are ready – What to Fix Before You Run a Single Ad covers the checklist that applies equally to agencies and to advertising.

If your marketing isn’t performing and you’re not sure whether an agency is the answer, Why Your Marketing Isn’t Working covers the four root causes that an agency won’t fix if they’re already present.

Frequently Asked Questions

How do I know if I need a marketing agency?
If your marketing needs are outgrowing what you can handle in-house and you have the budget to sustain an ongoing relationship, an agency can make sense. But before engaging one, be honest about whether your positioning, your website, and your follow-up process are ready. An agency can’t fix foundational problems – they can only do more on top of them.

How much should I expect to pay for a marketing agency as a small business?
UK marketing agency retainers for small businesses typically start from around £1,500-£2,500 per month for a limited scope, rising significantly for full-service relationships. Be cautious of very low retainers – the economics of running an agency don’t support meaningful work at below a certain level.

What’s the difference between a marketing agency and a marketing consultant?
An agency employs a team and operates at scale – which means layers of management, more structured processes, and typically higher cost. A consultant works more directly, usually with more senior involvement in the day-to-day. For smaller businesses, a consultant model often provides better access to strategic thinking at a lower overhead.

How long does it take to see results from a marketing agency?
Realistic timelines depend on the channels. SEO takes three to six months to show meaningful movement. Paid advertising can show signals in four to eight weeks. Content and LinkedIn authority build over six to twelve months. Any agency promising fast results across all channels is either overpromising or planning to focus on vanity metrics.
