What is digital marketing?

If you run a small business, digital marketing is one of the most cost-effective ways to reach new customers and grow your revenue. Understanding what it involves, and why it matters, is the first step toward building a strategy that works for your budget.

Digital marketing is any online activity designed to attract customers and generate sales for your business. It includes search engine optimization (SEO), social media posts, email campaigns, paid search ads, content creation, and website optimization. Unlike traditional marketing channels like print ads or direct mail, digital marketing lets you target specific audiences, measure results in real time, and adjust your spending as you learn what works.

For small businesses, the advantages are significant. You can reach customers well beyond your local area through search engines and social media, often at a fraction of the cost of traditional advertising. Studies show that 33% of local searches result in a purchase within 24 hours. Cost-effective marketing is especially important in the current climate: Xero Small Business Insights data shows US small business sales growth averaged just 2.4% year over year in 2025, roughly half the long-term average of 5.5%, making every marketing dollar count.

"Some startups spend their entire marketing budget quickly because the return on investment is strong," says online business consultant Marc McKeown of FortBrave. "They often earn back more than they spend."

Shaheman Farid of Boobooks Accountants agrees: "Businesses that monitor their campaigns closely are more likely to see positive returns."

This guide covers everything you need to get started: from building your strategy and choosing the right channels, to setting a budget and measuring your results. For a broader look at marketing approaches, see the complete guide on small business marketing.

How to build a digital marketing strategy

Before diving into specific tactics, it pays to step back and plan your overall approach. A clear strategy helps you spend your time and money on the channels most likely to deliver results for your specific business.

Research your competitors

Knowing what your competitors are doing online can help you spot opportunities and avoid wasting effort on approaches that are already crowded. You don't need expensive tools to get started.

Competitor research means studying how similar businesses market themselves online so you can find gaps and opportunities. Start by searching for your main products or services on Google and noting which businesses appear at the top. Look at their websites, social media profiles, and ad placements to understand what channels they use and what messages resonate with their audiences.

For free research, try these approaches:

• Search Google for your target keywords and study the top-ranking pages.
• Follow competitors on social media and note their posting frequency, content types, and engagement.
• Sign up for competitor email lists to see how they nurture leads.
• Check their Google Business Profile for reviews and customer feedback.

If your budget allows, paid tools like Semrush, Ahrefs, or Moz can reveal which keywords drive traffic to competitor websites, how strong their backlink profiles are, and where they run paid ads. Even free versions of these tools provide useful insights.

Define your target audience

Your marketing will be more effective when you know exactly who you're trying to reach. A clear picture of your ideal customer helps you choose the right channels, write better messages, and avoid wasting budget on people unlikely to buy from you. The guide on market research for small business covers the process in more detail.

A target audience is a specific group of people most likely to buy your product or service. Define yours by considering demographics (age, location, income), behaviors (where they spend time online, how they research purchases), and pain points (the problems your product or service solves). If you already have customers, look at your sales data to identify patterns.

Create a simple buyer persona that captures your ideal customer's key characteristics. For example, a local bakery might target "working professionals aged 28 to 45 within a 10-mile radius who value quality ingredients and convenience." This clarity shapes every marketing decision you make, from which social media platform to prioritize to the tone of your email campaigns.

Set goals and budget

Setting clear goals and a realistic budget keeps your marketing focused and measurable. Without both, it's easy to overspend on channels that aren't delivering results.

Your digital marketing budget is the total amount you plan to spend on online marketing activities over a set period. Start by defining what success looks like: more website visitors, phone calls, email subscribers, or direct sales. Then allocate your budget across channels based on where your target audience spends time online.

A practical framework is the 70/20/10 rule: allocate 70% of your marketing budget to proven strategies that already work, 20% to promising new ideas, and 10% to experimental approaches. This balances reliable results with room for innovation. Getting this balance right matters. Xero Small Business Insights found that while the broader US economy grew 5.1% in 2025, small business sales grew at less than half that rate, underscoring the need to invest marketing budgets where they deliver measurable returns.

Here's a worked example. A local bakery with a $500 per month marketing budget might allocate it like this:

• $350 (70%) on proven strategies: Google Business Profile optimization, weekly email newsletters, and regular Instagram posts.
• $100 (20%) on promising ideas: testing Facebook ads targeting local foodies or launching a short-form video series.
• $50 (10%) on experiments: sponsoring a local food blogger or trying a TikTok account.

"You don't have to break the bank to test ideas," says Ben Charlton, owner of Air8 Digital marketing agency. "I have clients spending small amounts per day to run ads on multiple platforms. They check results and focus on what worked."

McKeown recommends investing enough in marketing to reach your goals. "It's a numbers game. You need to get a lot of people to your site, so we recommend clients put a meaningful portion of their startup budget toward marketing."

Free digital marketing strategies

You don't need a big budget to start marketing your business online. Some of the most effective strategies are completely free, and they build long-term visibility that continues to pay off over time.

Free digital marketing uses organic methods like SEO, content creation, and social media to attract customers without ongoing ad spend. Charlton puts it simply: "I'm focused on free opportunities and haven't had to spend anything yet to get sales." Start with these foundational strategies before investing in paid advertising.

Set up your Google Business Profile

If you serve local customers, your Google Business Profile is one of the first things to set up. It's free and puts your business directly in front of people searching in your area.

Google Business Profile is a free tool that helps local customers find your business in Google Search and Google Maps. Research shows customers are 2.7x more likely to view a business as reputable when it has a complete profile. Setting one up takes less than an hour and can immediately improve your local visibility.

Set up your profile with these essentials:

1. Add accurate business hours and keep them updated for holidays.
2. Include your phone number, address, and website link.
3. Upload quality photos of your products, services, and location.
4. Encourage satisfied customers to leave reviews and respond to every review you receive.

Optimize for search engines (SEO)

SEO is one of the highest-value free strategies because it brings customers to your website exactly when they're searching for what you offer. It takes time to build, but the traffic it generates is ongoing and doesn't cost you per click.

Search engine optimization (SEO) is the process of improving your website so it ranks higher in search results for the keywords your customers use. For small businesses, this means making your website content relevant, useful, and easy for search engines to understand.

Olivia Park, a business owner, shares her approach:

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.

Start with these keyword research steps:

1. List 10 to 15 words and phrases your customers would type into Google when looking for your products or services.
2. Use free tools like Google Keyword Planner or Google Trends to check search volume and discover related terms.
3. Look at the "People also ask" section in Google search results for additional keyword ideas.
4. Use your findings to create or update website pages, blog posts, and product descriptions with these keywords placed naturally in titles, headings, and body text.

Local SEO deserves special attention if you serve a specific geographic area. Make sure your business name, address, and phone number (NAP) are consistent across your website, Google Business Profile, and any online directories. Include location-specific keywords on your website, such as "plumber in Austin" or "wedding photographer in Portland." Claim your listings on Google Maps, Yelp, and industry-specific directories to strengthen your local search presence.

AI tools like ChatGPT can help you brainstorm keyword ideas, draft initial content outlines, and generate meta descriptions, but always review and edit AI-generated content to make sure it matches your brand voice and includes accurate information.

Build your content marketing plan

Content marketing works hand in hand with SEO by giving search engines more pages to index and giving your audience reasons to visit your site. It also builds trust and positions you as an expert in your field.

Content marketing means creating and sharing valuable content, like blog posts, videos, or podcasts, to attract and retain customers. The key is to create content that genuinely helps your target audience, not just content that promotes your business. When people find your content useful, they're more likely to remember your brand when they're ready to buy.

Consider these content types based on your audience and resources:

• Blog posts: answer common customer questions, share how-to guides, and cover industry trends relevant to your audience.
• Video content: short tutorials, behind-the-scenes looks at your business, or customer stories. Video performs well on social media and search.
• Podcasting: if your industry lends itself to longer conversations, a podcast can help you build a loyal audience. Many small business owners find podcast interviews are a cost-free way to reach new customers.

Consistency matters more than volume. Publishing one high-quality blog post per week is more effective than posting five mediocre ones. A marketing plan template can help you map out your content calendar and stay on track.

Grow your social media presence

Social media gives you a direct line to your customers and a way to build a community around your business. The key is choosing the right platforms rather than trying to be everywhere at once.

Social media marketing means using platforms like Facebook, Instagram, LinkedIn, and TikTok to build brand awareness, engage with customers, and drive traffic to your website. When you share helpful advice or interesting stories, people are likely to share your content, expanding your reach organically.

Choose your platforms based on where your target audience spends time:

• Facebook: broad audience, strongest with ages 30 to 65. Good for local businesses, community building, and event promotion.
• Instagram: visual-first platform, strongest with ages 18 to 40. Ideal for retail, food, fashion, and lifestyle businesses.
• LinkedIn: the go-to platform for business-to-business (B2B) companies and professional services.
• TikTok: fastest-growing platform with ages 16 to 30. Works well for businesses that can create short, engaging video content.
• Pinterest: strong for home decor, food, fashion, and DIY businesses. Content has a longer shelf life than most other platforms.

Focus on 2 to 3 platforms where your audience is most active. Post consistently (3 to 5 times per week on most platforms), engage with comments and messages, and share a mix of helpful content, behind-the-scenes looks, and customer stories. Building a genuine community takes time, but it creates loyal customers who refer others to your business. For more on building loyalty, see the guide on how to get more clients.

Start email marketing

Email marketing puts you directly in your customers' inboxes, giving you a channel you fully control. Unlike social media, where algorithms decide who sees your posts, email reaches everyone on your list.

Email marketing means sending targeted messages to a list of people who have opted in to hear from your business. For many small businesses, it delivers the highest return on investment of any marketing channel.

Build your email list using these tactics:

• Offer something valuable in exchange for an email address, such as a discount code, free guide, or checklist.
• Add signup forms to your website, especially on high-traffic pages and at checkout.
• Collect email addresses at in-person events, in your store, or on receipts.

Once your list is growing, segment it based on customer behavior. For example, a clothing retailer that segments emails by purchase history and sends personalized product recommendations can see open rates 25% higher than generic blasts. At a minimum, separate new subscribers from existing customers so you can tailor your messages to each group.

Send a regular newsletter with a mix of valuable content, special offers, and business updates. Track your open rates and click-through rates to learn what resonates, and adjust your approach based on the data.

Encourage reviews and testimonials

Customer reviews do double duty: they build trust with potential buyers and improve your visibility in local search results. A consistent stream of positive reviews can be one of your most powerful marketing assets.

Online reviews are public feedback from customers that appear on platforms like Google, Yelp, and industry-specific sites. Reviews influence both purchase decisions and search rankings, with Google factoring review quantity and quality into local search results.

Build a systematic approach to collecting reviews:

• Ask customers for a review at the point of highest satisfaction, such as right after a successful delivery or service completion.
• Make it easy by sending a direct link to your Google Business Profile review page via email or text.
• Respond to every review, positive or negative, to show you value customer feedback.
• Feature your best testimonials on your website, social media, and marketing emails.

Paid digital marketing strategies

Once you've built a foundation with free strategies, paid advertising can accelerate your growth by putting your business in front of more people, faster. The advantage of paid channels is precise targeting and immediate visibility.

Paid digital marketing uses advertising spend to reach potential customers faster than organic methods. You control your budget and can target specific audiences based on demographics, interests, location, and online behavior.

Pay-per-click (PPC) advertising

PPC advertising is one of the fastest ways to appear at the top of search results for the keywords your customers use. You only pay when someone actually clicks your ad, giving you direct control over costs.

Pay-per-click advertising places your business at the top of search engine results pages, and you pay only when a user clicks through to your website. Google Ads is the most common PPC platform for small businesses.

Get started with Google Ads in these steps:

1. Choose keywords that match what your customers search for when they're ready to buy.
2. Set a daily budget you're comfortable with (start at $4 to $8 per day while testing).
3. Write ad copy that clearly states what you offer and includes a strong call to action.
4. Set geographic targeting to focus on the areas you serve.
5. Monitor results daily for the first 2 weeks, then adjust keywords and budgets based on what converts.

Charlton explains how to use PPC strategically: "I have a client who pays to appear when people search for a builder, but only if that person is within 15 miles, because my client doesn't want jobs that require a lot of travel."

Paid social media advertising

Paid social ads let you put your message directly in the newsfeeds of people who match your ideal customer profile. Different platforms suit different types of businesses, so choosing the right one matters.

Paid social advertising places your ads in the feeds of targeted users on platforms like Facebook, Instagram, and LinkedIn. These platforms offer detailed targeting options based on demographics, interests, behaviors, and even job titles.

Choose your platform based on your business type:

• Facebook and Instagram ads: best for business-to-consumer (B2C) brands. Strong visual targeting, lookalike audiences, and retargeting options. A good starting budget is $5 to $10 per day.
• LinkedIn ads: best for B2B companies and professional services. Higher cost per click, but the leads tend to be more qualified. Start with $10 to $20 per day.
• TikTok ads: growing option for brands targeting younger demographics. Lower cost per impression than more established platforms.

Display ads and retargeting

Display ads build brand awareness by showing your business across thousands of websites. When combined with retargeting, they become even more powerful by re-engaging people who've already shown interest in your products.

Display ads are visual banner advertisements that appear on websites and apps across the internet. According to WordStream research, 55% of companies use display ads as part of their digital marketing mix. Small businesses often get the most value from display advertising through retargeting, which shows ads specifically to people who have already visited your website.

Marc McKeown of FortBrave 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.

Here's a worked example. An online retailer spending $200 per month on retargeting ads targets visitors who abandoned their shopping cart. By showing those visitors ads with a 10% discount code, the retailer recovers $1,200 in sales that would have been lost, delivering a 6x return on ad spend. Retargeting typically costs less per click than standard display ads because you're reaching people who already know your brand.

Influencer marketing for small businesses

Influencer marketing isn't just for big brands with large budgets. Micro-influencers, those with smaller but highly engaged audiences, can be an affordable way to reach new customers who trust the influencer's recommendations.

Micro-influencer marketing means partnering with content creators who have between 1,000 and 50,000 followers in a niche relevant to your business. These creators often have higher engagement rates than larger influencers and charge significantly less.

To find the right influencers for your business:

• Search Instagram and TikTok for hashtags related to your industry and location.
• Look for creators whose audience matches your target customer profile.
• Start with a small test: one or two posts at $50 to $500 per post, depending on the influencer's following and engagement.
• Track results using unique discount codes or landing page links to measure the return from each partnership.

How to test and optimize your campaigns

Launching a marketing campaign is just the beginning. The businesses that see the best returns are the ones that test, measure, and refine their approach over time. This applies to every channel, not just paid ads. Understanding how your sales funnel works can help you identify where prospects drop off and where to focus your optimization efforts.

Campaign optimization means using data to improve the performance of your marketing activities over time. Follow a systematic testing approach for the first 3 months to identify your most effective channels.

1. Cast a wide net: try multiple platforms and ad types, including tactics you might initially dismiss.
2. Monitor key metrics: track views, click-through rates (CTR), cost per acquisition (CPA), and conversions for each campaign.
3. Run A/B tests: change one variable at a time (headline, image, audience, or offer) and compare results to find what performs best.
4. Focus on return on investment: identify which campaigns generate the best return on ad spend (ROAS) and direct more budget there.
5. Know when to cut: if a campaign hasn't shown improvement after 4 to 6 weeks of optimization, reallocate that budget to a channel that's performing.

Here's a worked example. A service business starts an email marketing campaign, growing its list from 200 to 2,000 subscribers over 6 months by offering a free consultation guide as a signup incentive. By segmenting the list and sending targeted offers, the business generates $8,000 in new bookings directly attributable to email, at a total cost of around $50 per month for email software. Tracking this return helps the business justify investing more in the channel.

Most advertising and email platforms provide detailed analytics. Review your numbers weekly and make adjustments based on what the data tells you, not on assumptions.

DIY or hire a digital marketing professional?

As your marketing efforts grow, you may wonder whether to keep managing everything yourself or bring in professional help. The right answer depends on your budget, available time, and how quickly you want to scale.

Choosing between DIY and professional help depends on your budget, time, and the complexity of the campaigns you want to run. Both approaches can work for small businesses at different stages.

McKeown notes that many platforms make DIY marketing accessible: "Many platforms help you create and launch ad campaigns, and they report results. But time can be a challenge when you are running your business."

Consider these options based on your situation:

• Under $1,000 per month: freelancers offer affordable expertise. Charlton suggests: "If someone charges you $200 and saves two days of your time, then spend the money. Try a LinkedIn post or look on a freelancer marketplace like Fiverr."
• Seeking lower costs: Farid recommends overseas talent: "We've discovered great talent at a quarter of the price in those markets. Make sure you help create the ads, as word choice can be challenging for people who aren't native English speakers."
• Over $1,000 per month: agencies become a viable option and can manage campaigns end to end.

When hiring a professional or agency, look for a portfolio of work with businesses similar to yours, relevant industry experience, transparent reporting on results, and clear communication about strategy and next steps.
