Key takeaways

• Start with one or two digital marketing channels based on where your target audience spends time online, as small businesses with a marketing plan are 6.7 times more likely to report success than those without a strategy.
• Test multiple approaches with small daily budgets of £4-8 for 2-4 weeks to identify what works before scaling up your investment on the most effective platforms.
• Focus on free marketing tactics like SEO, content creation, and email marketing first, since these methods can deliver sustainable results without ongoing advertising costs.
• Track specific metrics like cost per customer acquisition and conversion rates rather than vanity metrics, then double down on channels that deliver the best return on investment while pausing underperforming campaigns.

What is digital marketing?

Digital marketing is any online activity that promotes your business and drives sales. For small businesses, this includes social media marketing, email campaigns, search engine optimisation (SEO), and online advertising.

Smart targeting can deliver impressive returns, making digital marketing accessible even on a tight budget.

"Some startups spend their marketing budget quickly because the return on investment can be high," says online business consultant Marc McKeown of FortBrave. "They often earn back what they spend, and more."

Fellow online business consultant Shaheman Farid of Boobooks Accountants says that despite this great potential, some startups struggle with digital marketing. "I've seen businesses spend thousands on campaigns without getting a single conversion."

Both agree that small businesses succeed at digital marketing by testing different approaches in a controlled way to see what works. What can you try?

Benefits of digital marketing for small business

Digital marketing levels the playing field between small businesses and larger competitors. You can reach your ideal customers without the massive budgets traditional advertising requires.

Key benefits for small businesses include:

• Cost-effectiveness: start with free tactics or small daily budgets, unlike expensive print or TV advertising
• Precise targeting: reach specific customer types based on demographics, interests, and online behaviour
• Measurable results: track exactly how many people see your ads, click through, and make purchases
• Flexibility: adjust campaigns in real-time based on what's working
• Direct customer access: reach people where they already spend time online

Unlike traditional marketing, digital channels let you test small, learn fast, and scale what works.

Types of digital marketing

Digital marketing channels fall into two main categories: free methods that build organic reach over time, and paid methods that deliver faster results.

• Free marketing: build your audience through content creation, social media engagement, and search engine optimisation
• Paid marketing: accelerate growth through targeted advertising, sponsored content, and pay-per-click campaigns

Each approach has distinct advantages and works best for different business goals and budgets.

Olivia Park of Olivia Park Coaching uses free marketing methods successfully.

I don't spend money on advertising. I create content aimed at helping my target customer and share it on Instagram or via podcasts. It attracts enough new clients to keep me busy.

Ben Charlton owns Air8 Digital marketing agency and runs an online shop, so he tests digital marketing strategies daily. He says free marketing methods can be effective.

Most people get on the ad platforms and start spending straight away but you don't have to. There's lots of free value out there. Take care of that stuff first.

How to create your digital marketing strategy

A digital marketing strategy is a plan that outlines how you'll reach customers online and achieve specific business goals. Before you spend a penny, take time to map out your approach. This helps you focus your efforts and make your budget go further, and research shows that small businesses with a marketing plan are 6.7 times more likely to report marketing success.

Follow these four steps to create your strategy:

1. Set clear goals: define what you want to achieve, such as more website visits, more sales, or more customer enquiries
2. Know your audience: identify who you're trying to reach and where they spend their time online
3. Choose your channels: pick one or two channels to start with based on where your audience is (many small businesses find email marketing brings the highest return on investment)
4. Decide on a budget: figure out how much you can afford each month (according to recent data, B2B companies allocate an average of 9.4% of their revenue to marketing).

How much does digital marketing cost?

Digital marketing costs vary widely, but small businesses can start testing campaigns for as little as £4–8 per day. Many effective tactics, like SEO and content marketing, cost nothing but your time.

You can also find ways to advertise your small business for free or for a low cost.

Small budget testing makes digital marketing accessible for any business. Here's an effective low-cost approach:

• Daily budget: £4–8 split across 2–3 platforms
• Testing period: 2–4 weeks minimum per campaign
• Success metric: cost per customer acquisition
• Scaling strategy: increase spending on platforms that deliver results

If you have time, you can take a careful approach. Online startups often have low operating expenses, so you can test what works. However, McKeown recommends investing in marketing for long-term growth.

"It's a numbers game. You need to get a lot of people to your site so we recommend clients put 40% of their startup budget towards marketing. That's still not expensive when you consider what a bricks-and-mortar store would spend on signage and merchandising. That proportion of spending will come down once you've figured out what works."

McKeown explains how retargeting works.

Your ads can follow them around the internet for a little while. If they abandoned a cart, you can retarget them with an ad offering a discount or free delivery. If they already bought something, you could retarget them with an ad for a complementary product.

Ways to do digital marketing for free

Free digital marketing uses organic methods like SEO and content creation to attract customers without paid advertising. These tactics take more time but can deliver sustainable results.

Charlton's goal with his online shop was to spend nothing on advertising. "I'm focused on the free opportunities and haven't had to spend anything yet to get sales." SEO (search engine optimisation) and content marketing are the two main ways he attracts customers for free.

SEO marketing

Search engine optimisation (SEO) helps your business appear when potential customers search for your products or services online. This free marketing strategy can drive consistent, targeted traffic to your website.

Key SEO actions for small businesses:

• Claim your Google Business Profile: ensure local customers can find you, as research shows 76% of "near me" searches result in a visit to a business within a day.
• Connect to Google Shopping: display your products directly in search results
• Optimise your website content: use keywords your customers actually search for

Even though SEO can bring free traffic to your site, you may choose to invest in it. An SEO consultant can help you improve your search rankings.

Shareable content

Shareable content is helpful, entertaining, or relatable material that your audience wants to pass along to others. When you share useful advice or interesting stories on social media, you expand your reach without paying for ads.

Research shows 66% of marketers report funny content is most effective, followed closely by relatable and trendy content. Olivia Park of Olivia Park Coaching uses this approach successfully.

Email marketing

Email marketing sends targeted messages directly to people who have opted in to hear from you. It consistently delivers one of the highest returns on investment of any digital marketing channel, with a reported average ROI of £36 for every £1 spent in the UK.

Getting started with email marketing:

• Build your list: add signup forms to your website and offer something valuable in exchange for email addresses
• Choose a tool: free options like Mailchimp or MailerLite work well for small lists
• Start simple: send a monthly newsletter with helpful tips, then expand to promotional campaigns
• Track results: monitor open rates and click-through rates to see what resonates

The key advantage of email marketing is ownership. Unlike social media followers, your email list belongs to you and can't be affected by algorithm changes.

Paid digital marketing for small business

Paid digital marketing uses advertising spend to reach potential customers quickly. Unlike free methods, paid campaigns deliver immediate visibility and allow precise audience targeting.

The three main approaches are pay-per-click (PPC) advertising, social media advertising, and display advertising.

Pay-per-click

Pay-per-click (PPC) advertising puts your business at the top of search results immediately. You only pay when someone clicks on your ad, making it a cost-effective way to reach customers actively searching for what you offer, especially since PPC traffic converts 50% better than organic site visitors.

PPC works particularly well for small businesses because you can set daily budgets and target specific locations or customer types. 65% of small to mid-sized businesses have a PPC campaign.

Paid social (ads or sponsored content)

Paid social advertising places your ads or sponsored content in the feeds of your target customers on social media platforms. This channel accounts for 30% of digital advertising spend.

Most social platforms let you create detailed audience profiles based on demographics, interests, and behaviours. This targeting helps you reach your ideal customer without wasting budget on people unlikely to buy.

Display ads

Display ads appear as banners on websites across the internet. Small businesses typically use them for retargeting, which shows ads to people who have already visited your website.

Marc McKeown says retargeting can help you close a sale with someone who's previously been to your site.

How to measure your digital marketing success

Measuring digital marketing success requires tracking which campaigns deliver the best return on investment. Test multiple channels because what works varies by business.

Your testing approach should include:

• Start broad: test 3–4 different channels in your first three months
• Set small budgets: limit initial investment to reduce risk
• Track everything: monitor impressions, click-through rates, and conversions
• Double down: increase spending on channels that work and pause those that don't

Most advertising platforms show you campaign statistics, such as how many people saw your ad, the click-through rate, and the number of purchases. Track your results regularly, as what works now may change over time.

DIY or use a pro?

Choosing between DIY and professional help depends on your time, budget, and technical comfort level.

Many business owners take a DIY approach, and about 47% of them handle all marketing themselves. DIY digital marketing works when you have:

• Available time: 5–10 hours per week for campaign management
• Willingness to learn: comfort with new platforms and tools
• Limited budget: less than £1,000 monthly marketing spend

Professional help makes sense when you have:

• Limited time: need to focus on core business operations
• Need for expertise: require advanced strategies and optimisation
• Available budget: can invest £1,000+ monthly in marketing

Charlton says that agencies tend to work with businesses spending upwards of a thousand per month, so that may not be an option straight away. But he adds that freelancers can be a great way to start.

"If someone charges you £200 and saves you two days, it can be worth the investment. You may already know someone who can help with digital marketing for your small business. Since 40% of business-to-business marketers list LinkedIn as their most effective channel for finding high-quality leads, it can be a good place to start your search. Try posting on LinkedIn or look for freelancers on Fiverr."

Meanwhile Farid says not to be afraid of using overseas experts. "Just search for 'small digital campaign' and a good agency will find you! We've discovered some great talent at a quarter the price in those markets. Work with your freelancer to create the ads, as collaborating on wording can help ensure your message is clear and effective."

Getting started with digital marketing: Your first steps

Getting started with digital marketing doesn't require doing everything at once. Focus on these three foundational steps:

1. Claim your online profiles: set up your Google Business Profile and social media pages, keeping your business name, address, and phone number consistent everywhere
2. Start with one channel: pick one marketing type based on your strengths (if you're good at writing, start a blog; if you enjoy creating visuals, try Instagram)
3. Test and learn: run a small, low-cost ad campaign to discover what your customers respond to

Make digital marketing work for your small business

Precise targeting determines your digital marketing success. The more specifically you can define and reach your ideal customer, the better your results will be, particularly since 71% of consumers now expect personalized interactions from brands.

Effective targeting requires you to:

• Define your customer: identify their demographics, interests, and pain points
• Select your platforms: choose where your customers spend their time online
• Match your message: use language and tone that resonates with them
• Align with intent: match your content to their buying mindset

Create detailed customer profiles before launching any campaigns to ensure your messaging hits the mark.

Approach digital marketing with an open mind. Test different types and carefully track your results. Focus your budget on campaigns that deliver returns.
