Fractional CMO, Agency or Junior Marketer: Which Do You Need?
Paul Keene · 8 min read ·
SHORT ANSWER
Hire a junior marketer when the work is not getting done. Use an agency when you need a specialist skill, such as running Google Ads. Bring in senior judgement, such as a fractional CMO, when the work is getting done but nobody can say whether it is the right work. Many small businesses have the first two and are missing the third.
Key takeaways
- A junior marketer, an agency and a fractional CMO fill three different gaps: hands, specialist skills and judgement.
- A UK marketing executive typically earns about £22,000 to £35,000 a year. They bring energy and time, but rarely the experience to set strategy.
- Agencies are paid to do the work you ask for. They are seldom the ones to tell you it is the wrong work, or to recommend spending less.
- A fractional CMO sets priorities and holds everyone else to account. UK rates typically run from £750 to £1,400 a day.
- For most small businesses, the best value is a junior marketer or agency doing the work, plus a small amount of regular senior judgement on top. The one-minute check below tells you which gap you have.
When marketing is not producing enough sales, the usual reaction is to add something: another hire, a new agency, a bigger budget. Often the real problem is that the business has bought the wrong kind of help. This guide explains what each option does well, what it does not do, and how to tell which gap you actually have. It is written for owners of small and medium-sized businesses deciding where the next pound of marketing money should go.
What does a junior marketer do well?
A junior marketer, often titled marketing executive or marketing assistant, works for you full time and does the day-to-day work. They post on social media, send the newsletter, update the website, brief designers and pull together reports. Over time they learn your business, your customers and your products in a way no outsider can.
In the UK a marketing executive earns an average base salary of about £26,000, with most between £22,000 and £35,000 (PayScale, July 2026).
What they rarely have is the experience to decide what matters most, or the confidence to push back when something is not working. That is not a criticism. It is what junior means.
What does a marketing agency do well?
An agency brings skills you do not have in-house: paid search, SEO, design, video, social advertising. A good one has specialists who do nothing else all day, and tools you would not buy for yourself.
You pay a monthly fee, and for paid advertising often a percentage of ad spend on top. Agencies are good at executing a brief. They are less good at telling you the brief is wrong, partly because they see one slice of your business, and partly because a percentage-of-spend fee gives them little reason to recommend spending less. I set out how to check whether yours is performing in how to tell if your marketing agency is delivering.
What does a fractional CMO do well?
A fractional CMO is a senior marketer who works for you part of the week, usually one to three days. They decide where the budget goes, set priorities for the junior marketer and the agency, check the results and report on them. They bring the judgement that comes from having done the job before, often many times.
UK rates typically run from £750 to £1,400 a day, usually sold as a monthly retainer. The full breakdown is in what does a fractional CMO cost in the UK?
How do you tell which gap you have?
Ask three questions, in order.
- Is the work not getting done? Posts not going out, campaigns never launched, the website months out of date. You need hands: a junior hire or a freelancer.
- Is the work getting done, but one specialist area is going badly? Google Ads costing more each month, the site not showing up in search. You need a specialist: an agency or a contractor.
- Is the work getting done, but nobody can say whether it is the right work? Plenty of activity, reports full of clicks and likes, and no clear line from any of it to sales. You need senior judgement.
The third gap is the hardest to spot from the inside, because everyone looks busy. It is also the most expensive to leave open. A business can pay a junior marketer and an agency for years to be busy on the wrong things.
Why not just hire a senior marketer?
If marketing is big enough to need senior attention every day, you should. That usually means a sizeable team, a large budget, or a board that expects a marketing director in the room.
At Shufti Pro, a RegTech scale-up that grew from around 30 people to more than 250 while I was Marketing Director, a full-time senior marketer was essential. Most small businesses are not there yet. A UK marketing director's average base salary is around £79,000 before employer costs (PayScale, July 2026), and there is often not enough senior work to fill five days a week.
What combination works best for a small business?
For most small and medium-sized businesses, the answer is not choosing one. It is a junior marketer or agency doing the work, with a small amount of regular senior judgement on top. Someone experienced reads the numbers every week, says what to change and why, and checks that it happened.
That does not need two days a week. It needs someone senior who reads your data regularly and gives your team a clear, short list.
That is what The Monday List does. Every week I read your analytics, ads and sales data and send the changes most likely to make you money, with the reason for each. Your junior marketer or agency makes them, or I do.

Frequently asked questions
Can a junior marketer grow into a senior role?
Yes, with the right support. Junior marketers learn fastest when someone experienced explains why a change is being made, not just what to change. Without that, they tend to learn by trial and error, which is slow and costly.
Should my marketing agency set my strategy?
An agency can contribute ideas, but leaving strategy to it creates a conflict of interest. An agency paid on a percentage of spend is rarely the one to recommend spending less, or moving budget to a channel it does not run.
Is a freelancer a better option than an agency?
For a single, well-defined skill, a good freelancer can be better value than an agency. You usually get one experienced person rather than a team with junior staff doing much of the work. The trade-off is less cover for holidays and illness.
When should a small business hire its first marketing director?
When there is enough senior work to fill most of a week: a team to manage, a budget large enough that small percentage improvements pay for the salary, and decisions that need a marketer in the room every day.
Can I use a fractional CMO and an agency together?
Yes, and it is a common set-up. The fractional CMO sets the direction and holds the agency to account. The agency does the specialist work.
The bottom line
A junior marketer gives you hands, an agency gives you skills, and a senior marketer gives you judgement. Work out which you are missing before you spend more. For many small businesses the missing piece is judgement, and it costs far less than a hire.
