How to Choose a Marketing Agency: 15 Key Questions

To choose a marketing agency, start from your business goal, not from the agency’s list of services. Then check who will actually work on your account, what you receive each month, whether the accounts and data stay yours, how reporting works and what the contract says about length and exit. Ask the 15 questions in this guide before you sign anything.

What you actually need, before you start looking

Many business owners start looking for an agency when they feel that something is “not working” in sales. If you cannot say what you want to change, every agency will propose what it knows how to do, not what you need.

Before the first call, write down three things: the goal (for example more enquiries or more orders, with a rough figure), your total monthly budget (including advertising spend, which is paid separately from the agency fee) and what you already have (website, ad accounts, customer list, analytics). If you are not sure where you stand, a quick digital maturity scan shows where you are weak and where you already have solid foundations.

A short-term plan also makes proposals easier to compare: a serious agency should be able to say what your first three months would look like. If you do not have such a plan, see how to build a 90-day marketing plan and ask agencies to comment on it.

Terms worth knowing

A retainer is a fixed monthly fee for a defined set of activities. Media budget (ad spend) is the money paid to ad platforms such as Google or Meta; it is not part of the agency fee. A KPI is a key performance indicator that shows whether your goal is getting closer: enquiries, orders, cost per lead.

A full-service agency covers several channels under one roof; a specialist (or boutique) agency does one thing very well, such as paid advertising. A freelancer works alone, usually cheaper and more flexible, but with no backup if they fall ill or disappear. None of these is better in itself; it depends on what you need to solve.

The 15 questions to ask before signing

Put them in writing or ask them in a meeting, and note the answers. An evasive reply often tells you more than a polished one.

What goals do you set for my business, and how will you measure them?
Who will actually work on my account, and how many hours a month will they give it?
What do the first 90 days look like, week by week?
Which channels do you recommend I start with, and why not all of them at once?
Who owns the ad accounts, Analytics, Tag Manager, domain and hosting?
Will I have direct administrator access to all accounts?
What is included in the fee, and what is charged separately (creative, filming, landing pages, tools)?
How is the advertising budget paid: directly to the platform or through the agency?
What does a monthly report look like, and can I see a sample?
Which metrics do you track besides impressions and clicks?
What experience do you have with businesses like mine, and can I speak to a client?
How do we communicate: channel, contact person, response time?
What is the minimum contract length, and how can I leave?
What happens to materials, accounts and data if we end the relationship?
What can you not promise? (An honest answer to this one is worth a lot.)

The answers do not need to be perfect. They need to be specific, verifiable and free of guaranteed-results promises.

Warning signs during negotiation

Guaranteed results. Nobody can guarantee first place on Google or a set number of sales; too many factors lie outside the agency’s control.
Extremely low prices compared with other proposals, with no explanation of time and deliverables.
Refusal to give access to accounts, or insistence on running ads from the agency’s own account with no clear handover clause.
Vague promises: “we will grow your brand” or “optimise your online presence”, with no metrics or deadlines.
Long contracts with heavy exit penalties and no trial period.
Pressure to decide: “the offer expires tomorrow”.
References you cannot verify, or case studies with no context, no figures and no business name.
Reporting based only on vanity numbers (impressions, likes) with no link to sales.

A single warning sign does not automatically mean a weak agency, but two or three together should make you slow down.

What you should receive in practice

A serious proposal describes deliverables, not intentions. Ask for a list of what is produced each month, with quantities, deadlines and the person responsible. A rough example for a paid advertising service is: campaign structure, copy and creative, weekly optimisation, a monthly report and an analysis meeting.

Criterion	Agency	Freelancer	In-house team
Approximate cost	Medium to high	Medium to low	Highest (salaries, tools, training)
Range of skills	Several specialisms	Usually one or two	Depends on how many people you hire
Continuity	Good, with cover for absences	Depends on one person	Good, but exposed to staff turnover
Knowledge of your business	Builds over time	Builds over time	Deepest
Flexibility	High, within the contract	Very high	High, but with fixed costs

Compare proposals by deliverables and by what you can verify, not by price alone. Two offers with the same monthly cost can mean 5 hours or 25 hours of work a month.

Account access: who owns what

This is one of the most important conversations, and the easiest to neglect. The simple rule: you own the account, and the agency is a user with permissions. The ad account, the Google Analytics property, the Tag Manager container, the Facebook page, the domain and the hosting should be registered in your company’s name, or at least list you as administrator.

Why does it matter? If the relationship ends, your campaign history, audiences, conversion data and tracking pixels stay with you. Otherwise you start again from zero. Ask for the handover of access to be written into the contract, and clarify who pays for the content that is created (copy, images, videos) and who holds the rights to it.

For paid advertising, also check who funds the account: preferably your own card or your company’s, directly on the platform. That way you can see for yourself how much is being spent and you do not depend on someone else’s reports. To size the amount, see our guide to the online advertising budget.

Reporting: what an honest report looks like

A good report answers four questions: what we did, what happened, what we learned and what comes next. It includes indicators tied to your goal (enquiries, orders, cost per acquisition), not only impressions. It also shows what did not work, with an explanation and a plan.

Check whether the data can be confirmed independently: the figures in the report should be traceable in accounts you can access. Agree the rhythm at the start (monthly is a reasonable standard) and a short meeting to discuss the figures, not just a PDF sent by email. A set of indicators you can ask for is in our guide to the KPIs of a monthly marketing report.

Mind the timing too: the first weeks are for learning, especially with ads, so a fair report will not compare month two with the results of a whole year. The agency should tell you honestly what to expect and how soon.

The contract and the money: what to read closely

Pricing models vary, and each has strengths and limits. The most common are a fixed monthly fee, a fee as a percentage of media budget, and project-based pricing. There is no single “correct” one; what matters is that it is transparent and fits what you are buying.

Fixed fee: predictable, but check what it includes.
Percentage of media budget: can create an incentive to spend more; discuss caps and clear targets.
Per project: suits work with a clear start and end (a website, for example), with defined handover stages.

In the contract, look for the term and the conditions for ending it, the notice period, ownership of accounts and materials, confidentiality, personal data obligations (GDPR) and who is responsible for published content. For specific clauses, consult a lawyer; the text above is general information, not legal advice.

Common mistakes clients make

Choosing on price alone, without comparing deliverables.
No measurable goal, so no way to say whether it is working.
Delegating everything. An agency needs to know your products, customers and margins; without them, the messages sound generic.
Expecting results in two weeks from channels that need time to learn.
Switching agency at the first weak result, without analysing the cause.
Ignoring the website. If the page does not convert, better ads only bring traffic that does not buy.
No access to accounts, accepted “to keep things simple”.

How we go about it

We are an agency, so our interest is obvious. That is why we explain how we work, so that you can compare us with anyone else. We start with a conversation about goals and your starting point, then propose a plan for the first three months with clear deliverables. Accounts are opened in your name, and reports contain indicators tied to results, not only vanity figures.

We do not promise guaranteed rankings or sales, and we tell you directly when a service is not right for you. You can browse our services, read more about who we are or ask for a conversation through the contact form.

In short

Start from your goal, budget and the current state of your marketing.
Put the 15 questions in writing and compare answers, not just prices.
Insist that your company owns the accounts and the data.
Ask for concrete deliverables and a report tied to results.
Read the contract: term, exit, ownership of materials, GDPR.
If you are offered guaranteed outcomes or pressure to decide, slow down.

Roughly how much does a marketing agency cost?

It depends on the services, the time allocated and the team’s experience, so there is no single price. More useful than a figure is to compare proposals by deliverables: what is done each month, by whom, in how many hours. Ask for a breakdown and for what is not included. The advertising budget is paid separately from the fee.

What is the difference between an agency and a freelancer?

A freelancer works alone, usually more flexibly and more cheaply, but with no backup team. An agency brings several specialisms and continuity at a higher price. For a single channel, a good freelancer may be enough; for several coordinated channels, an agency is often more practical.

How long before results appear?

It varies by channel and starting point. Paid ads can give signals within a few weeks but need time to optimise; SEO and content are usually measured in months. An honest agency tells you from the outset what to expect realistically and when you will look at the first figures together.

Do I have to give the agency access to all my accounts?

Only to those needed for the contracted services, and through user permissions rather than your personal password. The accounts should stay the property of your company, with you as administrator. When the relationship ends, the agency’s access is removed and the history stays with you.

How do I check an agency’s references?

Ask for client names you can speak to and put concrete questions: how was communication, how clear was the reporting, what changed in their business. A case study with no figures or business name tells you little. Also look at the websites and public accounts of the clients mentioned.

Is a long-term contract worth it?

A longer contract can make sense if it brings a better price or the work needs time, but only with clear exit conditions and ideally a trial period at the start. Avoid heavy penalties and long notice periods. If you are unsure, begin with three months and review together.
