Marketing Agency vs In-House Marketing: Which Is the Better Investment?

9 Oct

As a business grows, there usually comes a point when marketing can no longer be something that gets done whenever someone has time.

You need consistent content. You want to improve your visibility on Google. Paid advertising needs to be managed properly. Social media needs attention. Your website needs updating. And now businesses also need to think about how they appear across AI Search platforms such as ChatGPT, Google AI Overviews, Gemini, Claude and Perplexity.

At that point, many businesses in Ireland and the UK face the same decision:

Should we hire someone internally to manage marketing, or work with a marketing agency?

There is no single answer that works for every business.

Hiring an in-house marketer can make a lot of sense in the right circumstances. But for businesses that need expertise across several areas of digital marketing, working with an agency can often provide access to a much wider range of skills without having to build an entire marketing department.

Marketing is no longer one job

One of the biggest challenges with hiring a single marketing employee is the sheer number of areas modern marketing can cover.

Depending on the business, your marketing might include:

Expecting one person to be highly skilled in every one of these areas is difficult.

This is one of the strongest arguments for working with a digital marketing agency.

Rather than hiring one person, you gain access to people with different skills who can work together on the same strategy.

This becomes particularly important when several marketing channels need to support one another.

A content shoot might create videos for social media and paid advertising.

SEO work might identify questions that should be turned into blogs or videos.

Paid advertising data might show which messages resonate most strongly with potential customers.

All of these insights can then feed back into the wider marketing strategy.

Marketing increasingly works as a connected system rather than a series of individual tasks. One of the sources we reviewed makes the same point, describing modern marketing as a combination of positioning, messaging, content, creative, website performance, lead generation, reporting and ongoing optimisation.

What are the advantages of hiring someone in-house?

There are good reasons to hire an internal marketing employee.

Someone working inside your company every day will naturally become very familiar with the business.

They are close to your sales team, management and customers. They can respond quickly to internal requests and may be particularly useful for businesses that need constant day-to-day marketing support.

For larger companies, an internal marketing manager can also provide valuable ownership.

They can manage priorities, coordinate internal teams and work closely with external partners.

In-house marketing can therefore work particularly well when marketing is central to the organisation and there is enough work to justify a dedicated role.

The challenge comes when one person is expected to become an entire marketing department.

Strategy, SEO, advertising, video production, design, copywriting, analytics and social media require very different skill sets. Research shared with us highlights this common problem, where businesses hire one person and expect them to perform the work of several different marketing specialists.

What are the advantages of working with a marketing agency?

The main advantage of working with a marketing agency in Ireland or the UK is access to a broader range of expertise.

Instead of employing one general marketer, a business can potentially access specialists across several disciplines.

For example, you might need:

SEO expertise to improve your Google visibility.

AI Search optimisation to increase your visibility across emerging search platforms.

A content team to produce photography and video.

Paid advertising expertise to manage Meta or Google campaigns.

Strategy to make sure all of those activities support the same objectives.

Hiring individual employees for every one of those roles would be unrealistic for many small and medium-sized businesses.

An agency gives businesses a way of accessing that wider skill set without having to create a large internal marketing team.

The cost of an employee goes beyond salary

When comparing a marketing agency vs hiring a marketing manager, it is important not to compare an agency retainer with salary alone.

Hiring an employee can also involve:

Employer costs
Pension contributions
Holiday pay
Sick leave
Recruitment
Training
Equipment
Software
Marketing tools
Professional development

There is also the time involved in recruitment and onboarding.

One of the sources provided for this article notes that businesses often underestimate the true cost of recruitment because they focus on the salary while overlooking training, benefits, technology and other employment costs.

That does not mean an agency will always be cheaper.

It depends on the type and volume of marketing support you need.

But the comparison should be between the total cost and capabilities of both options, rather than simply comparing a monthly agency fee with an employee's monthly salary.

An agency can give you more flexibility

Businesses change.

You might spend several months concentrating heavily on SEO and AI Search.

Then you launch a new product and need more content creation and paid advertising.

Later, you might need to focus more heavily on email marketing or lead generation.

An internal employee has a relatively fixed skill set and number of working hours.

An agency can usually move resources between different areas depending on what the business needs.

That flexibility can be particularly useful for growing businesses.

You might not need a videographer every week.

You might need a content shoot once a month or every two months.

You might not need a full-time SEO employee.

But you might want SEO and AI Search optimisation happening every month.

You might only need additional advertising support when launching a particular campaign.

With the right outsourced marketing package, those services can be combined based on what the business actually needs.

What about freelancers?

Freelancers can also be a very good option.

If you already know exactly what you need, hiring a specialist freelancer can make sense.

For example, you might need a photographer for a particular shoot, a graphic designer for a brochure or someone to manage a specific advertising campaign.

The challenge comes when you start hiring multiple freelancers for different parts of your marketing.

Someone then needs to coordinate everything.

The SEO specialist needs to understand what the content team is doing.

The advertising specialist needs the right creative.

The social media manager needs access to the content.

Someone needs to make sure the messaging is consistent.

Freelancers can provide excellent specialist support, but several separate freelancers do not automatically create a marketing strategy.

A source provided for this article makes a similar distinction. It suggests that contractors can work particularly well for clearly defined specialist tasks, while problems can arise when several specialists are working independently and nobody owns the overall strategy.

An agency can provide continuity

Another consideration is what happens when someone is unavailable.

An employee will naturally take annual leave and may eventually leave the company.

A freelancer may have limited availability or other client commitments.

With an agency, responsibility should sit with the wider team rather than one individual.

Good agencies will have processes for managing projects, sharing information and keeping campaigns running even when individual team members are unavailable.

For businesses that rely on consistent marketing activity, this can reduce the risk of everything stopping because one person is away.

Outside perspective can be valuable

An internal marketing employee understands your business extremely well.

That is a major advantage.

But sometimes being too close to the business makes it harder to see how customers experience it.

Businesses naturally start using their own internal terminology.

They assume customers understand services in the same way they do.

They repeat marketing messages because those messages have always been used.

An external marketing agency can bring another perspective.

Agencies work across different businesses and campaigns, meaning they see different approaches to content, advertising, SEO and lead generation.

That does not mean an agency automatically knows your business better than you do.

It means the best results usually come from combining your industry knowledge with the agency's marketing expertise.

When does hiring in-house make more sense?

There are situations where hiring someone internally may be the better investment.

If you need someone working on marketing every day, constantly collaborating with different departments and handling a very high volume of internal requests, an in-house marketer can be extremely valuable.

Larger companies may eventually build entire internal marketing departments.

In fact, one of the strongest models can be in-house marketing plus agency support.

An internal marketing manager can own the strategy and provide detailed knowledge of the business, while an agency provides specialist support in areas such as SEO, paid advertising, content production or campaign development.

The right decision depends on the size of the business and what marketing needs to achieve.

When does a marketing agency make more sense?

Working with a digital marketing agency in Ireland or the UK can make particular sense when:

You need expertise across several areas of marketing
Your current marketing is inconsistent
You do not have the budget or workload for a full internal marketing department
You need SEO, paid ads, content and social media to work together
You want to increase marketing activity quickly
Your existing team does not have enough time to manage marketing
You need specialist knowledge that you do not currently have internally
Your business is entering a growth phase

If several channels need to work together, coordination becomes increasingly important.

One of the frameworks provided for this article suggests that agencies tend to become particularly useful when businesses need a coordinated team, consistent execution and multiple marketing channels working together.

Think about what you are actually investing in

The decision should not simply be:

"What is the cheapest way to get our marketing done?"

A better question is:

"What marketing capabilities does our business need to achieve its goals?"

If your business only needs someone to publish a few social media posts every week, hiring a full digital marketing agency may not make sense.

But if you need strategy, content creation, SEO, AI Search optimisation, paid advertising, social media management and reporting, the comparison changes.

You are no longer comparing an agency with one employee.

You are comparing an agency with the team of people you would need to build internally to provide the same range of skills.

Marketing agency vs in-house marketing: which should you choose?

Neither option is automatically better.

The right choice depends on where your business is today.

Hiring an in-house marketer can provide valuable day-to-day ownership and a deep understanding of the business.

Working with an agency can provide a wider range of skills, additional capacity and greater flexibility.

For some businesses, the best approach will eventually be a combination of both.

What matters most is that your marketing has a clear strategy behind it.

Producing more social posts, launching ads or writing more blogs will not necessarily deliver growth if those activities are disconnected.

The aim should be to build a marketing system where the different channels support one another and are focused on reaching the right audience.
