There's no single right number — the common rule of thumb is 5 to 10% of revenue, more if you're pushing to grow. But the smarter way to set a marketing budget is to work backwards from what a customer is worth to you and what return you need, then spend on channels you can measure, not a blanket percentage.
Is there a standard percentage of revenue to spend on marketing?
The figure you'll hear most is 5 to 10 percent of revenue, leaning toward the higher end if you're actively trying to grow. It's a reasonable starting point, but it's a blunt tool — it tells you nothing about whether the spend actually pays you back.
What's a better way to set your budget than a fixed percentage?
Work from what a customer is worth and what you're trying to achieve. If one new customer is worth £1,000 to you, spending £200 to win them is a bargain. If a customer is worth £50, the maths is very different. Knowing your numbers — what a customer is worth and how many you want — tells you far more than any blanket percentage. Marketing is an investment, and the question is the return, not the cost. This is exactly why Juno's ideal clients are UK service businesses where a customer is worth £1,000 or more: the return on a proper engine is easiest to prove.
What should you fix before spending a penny on ads or SEO?
Make sure the thing your marketing points at actually works. Sending traffic to a website that does not convert is pouring water into a bucket with a hole in it. A website built to convert is where your marketing budget either pays off or leaks away — get this right first, before you spend a pound on attracting more visitors to it.
Where should the budget actually go?
Put it into things you can measure and improve:
- SEO and content — for enquiries that compound over time without paying per click.
- Google and Meta ads — for enquiries now, judged on cost per enquiry. See SEO vs Google Ads.
- Automation and AI — to make sure none of the enquiries you pay for get wasted through slow or missed follow-up.
If you cannot measure what a pound of spend brings back, you cannot improve it.
Why do most marketing budgets fail to pay back?
The most common mistake is splitting a small budget across too many channels, so none of them gets enough to work. Better to do one or two things properly than five things badly. Focus, measure, and scale what pays.
How does an engine change the return on your budget?
Most marketing spend leaks at the join — between the ad and the enquiry, between the enquiry and the booked appointment. The engine closes those gaps: it attracts visitors, captures every enquiry, qualifies it, books it, chases it if it goes quiet, and reactivates it later if it doesn't convert first time. Built bespoke, it can be live in 14 days, which means budget you spend this month can start paying back within weeks, not quarters.
The right marketing budget is not a fixed percentage. It is whatever brings back more than it costs, spent on things you can measure, pointed at an engine that doesn't waste what it earns.

Frequently asked questions
How much should a small business spend on marketing?
A common rule is 5 to 10 percent of revenue, higher when growing. But a better guide is what a customer is worth and what return you need. Marketing is an investment judged on return, not cost.
What should I spend my marketing budget on first?
Get the foundation right first: a website that converts. Then put budget into measurable channels like SEO and paid ads, with automation to make sure no enquiry you pay for is wasted.
Why is my marketing budget not working?
Often it is spread too thin across too many channels, or it points at a website that does not convert. Focus on one or two things done properly, and make sure the destination works before you spend more on traffic.
Is marketing a cost or an investment?
An investment, when done right. If you know what a customer is worth and you can measure what each pound brings back, marketing should return more than it costs.
How much does Juno charge to build a marketing engine?
There are no fixed packages. Most builds are a one-off setup plus a monthly fee, sized to your business and what a customer is worth to you, confirmed after a free call.
How is spending on an engine different from spending on ads alone?
Ads alone stop the moment you stop paying. An engine attracts, captures, qualifies, books and chases every enquiry automatically, so the same budget converts more of what it earns instead of leaking at the join.
