Introduction

I’ve spent most of my career in marketing. I started as a marketing executive, worked my way up through coordinator, and eventually Marketing Manager & Head of Marketing roles, and I’ve briefed more agencies than I can remember. Now I run one. Which means I’ve also sat on the other side of the table in pitches, answered the hard questions, won some, lost some, and occasionally nodded along politely while a prospect told me about the agency that promised them the moon and delivered a Canva template.

So yes, I have opinions about how you should choose a marketing agency. I’ve learned them the hard way. This is the honest version of that advice. Just the stuff we wish every business owner knew before they signed on a dotted line.

First, a confession about the word “agency”

The word “agency” could be misleading – now more than ever. Freelancers call themselves agencies. Global networks with 2,000 staff call themselves agencies. A bloke with a MacBook and a Wix subscription could also call himself an agency. Technically they could all be right, but depending on what you’re looking for one could suit you better than the other. So before we talk about how to choose one, let’s sort out what you actually need.

Here’s the short version:

Full-service creative agencies (like us, hi) do a bit of everything under one roof: branding, design, websites, marketing, content, and increasingly, automation and AI. They have a healthy mix of experts and specialists in each key service area they cover. Handy when you want one phone number to call and you’re tired of project-managing six vendors yourself.
Branding agencies focus on strategy, positioning, and identity. Great if you’re rebranding or starting fresh. Less great if what you actually need is more leads next Tuesday.
Performance or digital marketing agencies live in paid media, SEO, and analytics dashboards. They know their way around a CPC and will talk to you about attribution for hours if you let them.
Boutique studios are small, opinionated, and usually run by the people who will actually do the work. Senior talent, fewer layers, often better outcomes if the scope matches their wheelhouse.
Specialist shops do one thing. Video. SEO. Copywriting. If you need a scalpel, don’t hire a Swiss Army knife.
The right agency for you depends entirely on what you’re trying to achieve. Which brings us to step one.

Step 1: Work out what you actually want (before anyone tries to sell you something)

Most agencies will happily build you a website. Fewer will stop and ask whether a website is the thing holding your business back in the first place. Before you take a single sales call, write down the answers to these questions:
– What does success look like in six months? In twelve? In two years?
– What’s the actual business problem behind the marketing request? (More leads? Wrong leads? No one knows who you are? Customers love you but won’t pay more?)
– Who are you trying to reach, and why would they care?
– What’s your budget, honestly, and what’s the cost of doing nothing?

If you can’t answer these in plain English, don’t panic. But do know that a good agency will ask you all of them in the first meeting, and will gently push back if your answers contradictbeach other. Which they usually do. Write it down. Bring it to every meeting. It will save you months.

Step 2: Look past the shiny portfolio

Every agency portfolio looks great on a big monitor with a glass of wine. That’s the point. What you can’t see on a portfolio page is the bit that matters most: the thinking behind the work.

When you’re reviewing work, ask:

• What was the client trying to achieve, and did this achieve it?
• What did the business look like before, and what does it look like now?
• What would they do differently with hindsight?

If the agency can only tell you about the creative process and not the commercial outcome, that tells you something. Not necessarily bad, but something.

Industry experience is useful, but don’t overweight it. An agency that has worked with fifty SaaS companies might, on the surface, appear as “SaaS marketing experts”. But they may have only implemented a re-usable email automation flow for all of them and nothing else. An agency that has never worked in your sector might ask fresher questions and see things the incumbents have stopped noticing. Use your judgement. Ask questions about the results they delivered.

Step 3: Work out whether they actually think, or just nod

This is the bit most people get wrong. If you want someone to agree with every idea you have, hire a yes-person and pay them less. If you want a partner who will improve your thinking, you need an agency that pushes back when it matters.

In your first two meetings, test for this. Describe a recent decision you made or a current problem. Watch what they do.

Warning signs:

• They start pitching solutions before they understand the problem.
• They agree with everything. (Either they don’t care or they don’t know enough to disagree. Both bad.)
• They dismiss things your team already knows.
• They have one approach and it suspiciously works for every business they’ve ever met.
• Every question you ask gets answered with a case study.

Good signs:

• They ask questions you hadn’t thought of.
• They say “we’re not sure yet, we’d want to dig into that” when it’s true.
• They tell you something you didn’t want to hear.
• They admit what they’re not good at and refer you elsewhere when it makes sense.

If you finish the meeting having learned something useful about your own business, that’s an agency worth talking to again. If you finish feeling flattered and nothing else, be a bit suspicious.

Step 4: Ask about the process. Really ask.

A portfolio shows you the finished product. The process is what determines whether you’ll actually get there, on time, without wanting to throw your laptop off a roof. Ask:

• Walk me through what the first month of working together looks like, week by week.
• Who runs the project day to day? Who checks the work?
• What happens when we disagree? What happens when something goes wrong?
• How many rounds of feedback are included? What happens when we need a fifth?
• How do you handle scope creep? (Trick question. The answer is never “we don’t have any.”)
• What’s your preferred way to communicate, and how often?

If the answers are vague, hand-wavy, or rely heavily on the word “flexible,” ask again. A good agency has been burned enough times to have a proper answer.

Step 5: The pitch team is not the project team

This is the single most useful thing in this whole blog post, so read it twice.

At many agencies, the people who show up to the pitch are not the people who do the work. The Managing Director charms you at the first meeting. The Creative Director sketches something beautiful on the whiteboard. You sign the contract. Then you get handed to a junior account manager and a freelancer you’ve never met.

It’s not always sinister. Senior people have to sell, and juniors have to learn. But you deserve to know.
Ask, out loud, in the second meeting:

“Who from this room will actually be on our account day to day? Can we meet them before we decide?”

Watch the body language. A good agency will happily introduce you to the team, because they’re proud of them. A less good agency will pivot to reassuring you about “senior oversight” and “checking in on the work.” Those phrases are often code for “the partners will pop in occasionally to check the juniors aren’t on fire.” Meet the doers. If you like them, great. If you don’t, that’s your answer.

Step 6: Run a working session before you sign

A pitch is theatre. A working session is the truth.

Before you commit to a big engagement, run a small paid project first. A discovery workshop. A brand audit. A single landing page. Something that costs less than your annual coffee budget but gives you a real taste of how the agency behaves when money changes hands and deadlines land.

You’ll learn more in two hours of real collaboration than in twenty pitch meetings. You’ll find out whether they listen. Whether they hit deadlines. Whether they escalate problems early or hope you won’t notice. Whether their Slack replies are useful or just “on it!” in different fonts.

If the small project goes well, the big one probably will too. If it doesn’t, you’ve saved yourself a fortune.

Step 7: Score them objectively

Most businesses don’t have the time, tools or technical background to audit their own website, rewrite their content strategy, and implement Schema markup on top of running their actual business. That’s exactly where we come in.
At Grendesign, we go through your website in detail, find exactly where the technical issues are, assess how well your content is positioned for both traditional search and AI-driven results, and give you a clear, prioritised plan for fixing it.

By the time you’ve met three or four agencies, they start to blur. The one with the nice office. The one that made you laugh. The one with the suspiciously polished deck. You need an objective way to compare them.

Here’s a simple scorecard. Rate each agency from 1 to 5 on each row, then add it up.

Strategic thinking

• Asks good questions about the business, not just the marketing.
• Shows genuine understanding of your industry or a willingness to learn it.
• Has a clear method for turning your goals into a plan.
• Will say “no” when it serves you.

Relevant experience

• Portfolio shows work for businesses at a similar stage to yours.
• Can point to real outcomes, not just finished work.
• Case studies show problem-solving, not decoration.
• References actually return your calls.

Team and culture fit

• You like the humans. This matters more than you think.
• Communication style suits your team.
• Values line up with yours, at least enough that you’ll survive disagreements.
• The team doing the work is the team you’d hire yourself.

Process and operations

• Clear, documented way of working.
• Realistic timelines. Suspicious of anyone quoting a two-week rebrand.
• Transparent pricing with no surprise line items later.
• Sensible approach to feedback, revisions, and scope changes.

Honesty

• Told you something you didn’t want to hear.
• Admitted what they’re not good at.
• Gave you a straight answer to a hard question.

Total it up. The highest score isn’t always the winner. But if one agency is miles ahead of the others, that’s rarely an accident.

The questions we wish more clients asked us

If you want to really stress-test an agency, these questions do the work of five.

• “Tell me about a project that went sideways. What happened, and what did you change afterwards?”
• “What kind of client do you work worst with?”
• “Who’s your best ever client, and what made that relationship work?”
• “What would make you walk away from our account?”
• “What’s a thing you used to believe about marketing that you don’t believe anymore?”

The answers tell you whether you’re dealing with a thoughtful business or a sales machine. You can tell within about three minutes.

A short word about price

Cheap is usually expensive. Not always, but usually.

The cheapest quote on the table is often the one where someone has either underestimated the scope (you’ll pay more later) or underpaid their team (you’ll get lower quality). Both of these end up costing you more than if you’d paid a fair price the first time.

At the same time, expensive isn’t a guarantee of anything. Some of the most impressive-looking agencies charge enterprise rates for work that could be done just as well by a smaller team with less overhead to feed.

Ask what’s included. Ask what’s not. Ask what happens if things take longer than planned. And compare like for like, not just bottom-line numbers.

The short version, for people who skim

1. Work out what you actually need before anyone tries to sell you something.
2. Look past the portfolio to the thinking behind it.
3. Test for genuine disagreement, not flattery.
4. Ask about the process in real detail.
5. Meet the team who will actually do the work, not just the pitch team.
6. Run a small project before you commit to a big one.
7. Score agencies objectively so you don’t just hire the one you liked most over sushi.

One last thing, from us

The right agency will feel a bit like hiring a good doctor. They’ll ask you questions you weren’t expecting. They’ll tell you things you don’t want to hear. They’ll push back when you’re wrong, and own it when they are. And when things click, they’ll know your business almost as well as you do, sometimes better.

That kind of partnership is worth looking hard for. Don’t settle for less.
