Marketing agency: how to choose one, what it costs and what to expect

A marketing agency can save you months of trial and error, but it can also spend your budget without measurable results. When you search Google for “marketing agency”, you will see dozens of firms promising growth, more customers and better numbers. You often cannot tell the difference between them from their websites.

This article is for business owners deciding whom to entrust their marketing to. We look at what an agency actually does, how you pay, when a freelancer or your own marketer is better, which questions to ask before signing a contract and what to watch out for. At the end you will also find a view on why some industries, such as the equestrian business, benefit from a specialised agency.

What a marketing agency does and which types exist

The term marketing agency covers very different companies. Some will build your entire brand from logo to campaigns, others do just one discipline in depth. Before you start comparing offers, be clear about which type you actually need.

• Full-service agency: covers strategy, branding, website, content, advertising and reporting. The advantage is a single partner; the disadvantage is a higher price and the risk that some areas are done only averagely.
• Performance agency: focuses on paid advertising (Google Ads, Meta, possibly other networks) and measurable conversions.
• Creative and branding agency: brand identity, campaigns, photo, video, copy. It pays less attention to technical measurement.
• SEO agency: the technical state of the website, content, keywords and links. Results come more slowly but last.
• Social media agency: profile management, creating posts, community, often also advertising on Instagram and Facebook.
• Specialised (niche) agency: works for one industry, such as hospitality, healthcare or equestrian sport, and combines several disciplines with knowledge of the market.

Online vs. offline: what an online marketing agency means

An online marketing agency, often called a digital marketing agency, works with channels that can be measured precisely: the website, search engines, social media, email, paid advertising. Offline marketing includes print, billboards, radio, events and trade fairs.

For most small and medium-sized businesses, the online part is now the core of marketing, because it can be started with a smaller budget and adjusted along the way. Offline activities should not be thrown away, however. In some industries, such as competitions, trade fairs or local services, they still have a strong influence, and a good agency can connect both worlds.

How much a marketing agency costs: collaboration models

There is no single answer to “how much does it cost”. The price depends on the scope, the number of channels, the difficulty of the market and the team’s experience. It is more useful to understand how you pay, because the pricing model also affects what the agency is motivated to do.

Model	How it works	When it fits	What to watch out for
Monthly retainer	A fixed monthly sum for an agreed scope of work	Long-term management of campaigns, social media, SEO	A precisely defined scope and deliverables, notice period
Project	A one-off price for a specific deliverable	New website, branding, audit, campaign launch	Number of revision rounds, what is out of scope
Hourly rate	You pay for time worked	Consultations, smaller changes, irregular work	Timesheets, a monthly cap
Performance model	Fee tied to results or a percentage of the ad budget	E-shops and businesses with precise conversion tracking	How results are measured and who influences their quality

Remember that with advertising you pay for two different things: the agency’s fee for its work and the media budget, which goes directly to Google or Meta. These items should be clearly separated in the offer. Combinations are also common, for example an initial project (audit, tracking setup) followed by a monthly retainer.

Agency, freelancer or in-house marketer?

An agency is not always the best choice. The size of the business, the budget and how much capacity you have to manage marketing internally all play a role.

Option	Strengths	Weaknesses	Suitable for
Freelancer	Flexibility, direct communication, usually lower costs	Limited capacity, dependence on one person, narrow specialisation	One clear task, such as managing ads or writing copy
In-house marketer	Knows the company in detail, available every day	Salary and contributions, one person cannot cover all disciplines	Companies with a regular agenda and their own product
Agency	A team of several specialists, tools, cover for absences	Higher price, risk of being the “small client” nobody looks after	Companies that need several channels at once or a fast start

In practice, a combination also works well: an in-house person holds knowledge of the company and communication with customers, while the agency supplies strategy, campaigns and technical skills. Whatever you choose, the foundation should be an online marketing strategy with clear goals, otherwise nobody will be able to measure whether the collaboration works.

How to choose a marketing agency: 10 questions before signing

The first meeting is more of an interview than a presentation. These questions will help you tell who understands your business and who is selling a template.

1. What similar projects have you worked on, and can I speak to one of the clients?
2. Who exactly will work on my account and who is my contact person?
3. What goals do you propose for the first 3 and 12 months, and how will we measure them?
4. What exactly is included in the price, and what is charged extra?
5. In whose name will the ad accounts, Analytics, domain and website be set up?
6. How often and in what form will I get a report?
7. What is the notice period, and what do I get when the collaboration ends?
8. Will you explain every major change and the reason for it?
9. What experience do you have with my industry and my customers?
10. What will you need from me, how much time and which materials?

Google recommends asking similar questions in its guide Do you need an SEO?, where it emphasises examples of previous work, references and a willingness to explain every change.

Warning signs when choosing an agency

Some mistakes are made again and again. If you come across any of these signs, slow down and ask more questions.

A guaranteed first place on Google

In the guide mentioned above, Google states directly that nobody can guarantee a number one ranking and advises looking for someone else if an SEO supplier promises it. Also be careful with unsolicited emails offering “fast SEO” and with claims of a special relationship with Google. What honest search work looks like can be found in our SEO optimisation guide.

Unclear reports

A report full of charts about reach and “impressions” with no connection to enquiries, bookings or sales tells you nothing. Ask what has changed, why, and what the agency will do next month.

Accounts and data that do not belong to you

Ad accounts, domain, website, Google Analytics, Search Console and business profiles on social media should be owned by the client. The agency gets access, not ownership. With Google Ads it is worth knowing that a client account can only have one owner and that an agency’s manager account automatically becomes the owner if it creates the account itself. The rules are described in the Google Ads help article on client account ownership.

Likewise, in Google Analytics keep the administrator role yourself and give the agency only the role it needs. How user management works is explained in the Google Analytics help centre. The same applies to Meta: the agency should be added as a partner to your business portfolio, not own the page or the ad account.

Onboarding, the first 3 months and measuring results

A good online marketing agency does not start with a campaign but with understanding. The first months should follow a clear logic so that you know what you are paying for.

Month 1: audit and setup

An introductory workshop on the company, customers and competitors, access to accounts, a check of tracking (conversions, forms, phone calls). The output is an audit of the current state and a plan with priorities.

Month 2: first campaigns and content

Launching the first activities according to the plan, such as website changes, first articles or Facebook advertising and Instagram. Budgets are usually more cautious at first; the goal is to collect data.

Month 3: evaluation and adjustments

The first serious evaluation: what works, what to switch off, where to move the budget. With SEO, do not expect final results yet; with paid advertising you should already see the direction.

How to measure the results of the collaboration

• Business metrics: the number of enquiries, bookings, orders and their value.
• Cost per result: how much one enquiry or customer costs you.
• Organic traffic and rankings for important keywords over time.
• Lead quality: whether new prospects match your ideal customer.

What long-term growth in organic traffic looks like in practice is shown in our SEO case study.

Why a specialised marketing agency helps the equestrian business

The equestrian world has its own rules. A stable’s customer is not an anonymous consumer but a rider, parent or horse owner who decides based on recommendations, expertise and how horses are treated at the stable. A general agency learns this logic at your expense; a specialised one knows it from day one.

In practice this means the right terminology (show jumping, dressage, the show ring), knowledge of the competition season, contacts in the community and sensitivity to welfare. In equestrian sport, trust also matters more than sheer reach, as we write in the article why trust has overtaken reach in equestrian branding. Our whole approach to strategy for stables, clubs and brands can be found in the guide to equestrian marketing.

We at EQUILABZ have also focused specifically on the equestrian world. If you are interested in what such a collaboration looks like, take a look at our services and portfolio.

Frequently asked questions

How much does a marketing agency cost?

The price depends on the scope, the number of channels and the collaboration model: a monthly retainer, a project, an hourly rate or a performance model. With advertising, add the media budget itself to the agency’s fee. Always ask for a breakdown of what is included.

What is the difference between a marketing agency and an online marketing agency?

An online (digital) marketing agency works with the website, search engines, social media, email and paid online advertising. A general marketing agency may also do offline activities such as print, events or outdoor advertising.

When is a freelancer better than an agency?

When you need one clearly defined task, such as managing ads or writing copy, and you have time to manage the collaboration. If you need several channels at once or cover for absences, an agency is more suitable.

Can an agency guarantee first place on Google?

No. Google itself states that nobody can guarantee the top position. Instead of guarantees, a serious agency will present a plan, metrics and a realistic timeframe.

When will I see the first results?

With paid advertising, usually after the first weeks and months of testing. SEO and brand building are long-term, so agree at the start on interim metrics by which you will judge the direction.

In conclusion

A good marketing agency is not the one with the most beautiful presentation, but the one that understands your customers, bills transparently, leaves you ownership of accounts and data and regularly shows results tied to the business. Prepare your goals, ask the right questions and treat the first three months as a trial period for both sides.
