How Much Should a Small Business Spend on Marketing?

One of the most common questions business owners ask is, "How much should I spend on marketing?"

Unfortunately, there isn't a simple answer.

Spend too little and your business may struggle to grow. Spend too much without a clear strategy and you could waste valuable resources on activities that don't generate a return.

The key isn't spending more. It's spending smarter.

In this guide, we'll explain how to set a realistic marketing budget, where to invest your money and how to measure whether it's working.

Why every business needs a marketing budget

Many small businesses treat marketing as an occasional expense.

They run an advert when sales slow down, post on social media when they have time or redesign their website every few years.

Successful businesses take a different approach.

Marketing is treated as an ongoing investment rather than a last-minute solution.

Having a dedicated budget allows you to plan ahead, measure results and make informed decisions instead of reacting when business becomes quiet.

How much should you spend?

A common guideline is:

• Start ups and businesses looking to grow: 10% to 20% of annual revenue.

• Established businesses maintaining growth: 5% to 10% of annual revenue.

These figures are only a guide.

A business launching a new product, entering a new market or increasing brand awareness may need to invest more.

The important question isn't, "How much should I spend?"

It's, "What return am I expecting?"

Focus on return, not cost

Marketing should generate measurable results.

For example, if you spend £1,000 on marketing and generate £8,000 in new business, the investment has clearly paid for itself.

Instead of looking at marketing as an expense, consider it an investment in future revenue.

The most effective marketing activities continue delivering results long after they've been completed.

A well-written blog, an automated email journey or an optimised website can continue generating leads for years.

Where should your budget go?

Every business is different, but your budget is often spread across several key areas.

Website

Your website is your digital shop window.

It should clearly explain what you do, build trust and encourage visitors to take action.

Investing in website improvements often increases the effectiveness of every other marketing activity.

Search Engine Optimisation (SEO)

SEO helps potential customers find your business through search engines.

Unlike paid advertising, the benefits of SEO build over time, making it one of the most sustainable long-term investments.

Answer Engine Optimisation (AEO)

More people are using AI tools such as ChatGPT, Gemini and Perplexity to search for businesses and services.

Creating helpful, authoritative content improves the likelihood of your business being recommended in AI generated responses.

AEO is becoming an essential part of modern digital marketing.

Content marketing

Helpful content builds trust and demonstrates expertise.

This could include:

• Blog articles

• Case studies

• Guides

• Videos

• FAQs

• Email newsletters

Content also supports your SEO, AEO and social media strategy.

Email marketing

Email marketing remains one of the highest return on investment marketing channels.

Rather than constantly finding new customers, email marketing helps you build stronger relationships with the customers you already have.

Paid advertising

Platforms such as Google Ads and Meta Ads can deliver excellent results when managed effectively.

However, advertising works best when your website is already converting visitors into customers.

Driving traffic to a poorly performing website rarely solves the underlying problem.

CRM and automation

Investing in CRM software and automation tools can improve customer experience while saving significant amounts of time.

Automated processes help businesses nurture leads, follow up enquiries and retain customers more efficiently.

Common marketing budget mistakes

Many businesses make the same mistakes when planning their marketing spend.

Spending everything on advertising

Advertising generates visibility, but it won't fix poor messaging, confusing websites or weak customer journeys.

Ignoring existing customers

Winning new customers is often more expensive than retaining existing ones.

A strong email marketing and CRM strategy can significantly increase repeat business.

Measuring the wrong metrics

Likes, followers and impressions may look impressive, but they don't always generate sales.

Instead, monitor:

• Enquiries

• Conversion rates

• Revenue

• Customer acquisition cost

• Customer lifetime value

• Return on investment

These figures provide a much clearer picture of marketing performance.

Expecting immediate results

Some marketing activities deliver quick wins.

Others, particularly SEO and content marketing, require patience.

The businesses that achieve long-term success usually invest consistently rather than expecting overnight results.

How to prioritise your marketing budget

If your budget is limited, focus on building strong foundations before expanding into additional channels.

A sensible order might be:

1. Optimise your website.

2. Create clear messaging.

3. Improve conversion rates.

4. Invest in SEO and AEO.

5. Develop email marketing.

6. Add automation.

7. Scale with paid advertising.

This approach helps maximise your return at every stage.

Should you outsource your marketing?

Many small businesses don't need a full-time marketing employee.

Working with a consultant or marketing agency gives you access to specialist expertise without the cost of employing an in-house team.

The right support helps you avoid expensive mistakes and ensures your budget is invested where it will have the greatest impact.
