How to build a digital marketing strategy for a small or medium business

A useful digital marketing strategy for a small or medium business fits on a couple of pages. It says what the business needs from marketing, how that will be measured, which channels will do the work, how much it will cost and how often results will be reviewed. Anything longer is usually hiding a lack of decisions.

Here is how to build one.

Step 1: Start with a commercial target

Begin with a business number, not a marketing one. For example:

• "Grow online revenue by 25% this year without increasing the cost of each sale."
• "Fill 80% of course places each month."
• "Generate 30 qualified enquiries a month for our commercial services."

Work back from that. If you need 30 enquiries and a third of them become clients, you need ten new clients a month. That tells you how much you can afford to spend to win each one.

Step 2: Fix the measurement first

You can't run a strategy you can't measure. Before you choose channels, make sure you can see:

• Which enquiries or sales came from which source.
• What each channel costs.
• What happens after the enquiry: how many become clients and how much they are worth.

That means working conversion tracking in GA4 and your ad platforms, tracked phone numbers if calls matter, and a CRM or at least a spreadsheet that records where each lead came from. This is unglamorous work, and it is the most valuable part of the strategy.

Step 3: Understand where demand comes from

Look at how your customers find businesses like yours:

• Do they search for it? Then search matters: Google Ads now, SEO over time.
• Do they need to see it? Then Meta and other social channels matter.
• Do they ask questions and research? Then useful content, and possibly ChatGPT Ads, matter.
• Do they ask friends and colleagues? Then reviews, referrals and your reputation matter.

Use your own data where you have it. Ask recent customers how they found you and what nearly stopped them buying.

Step 4: Choose a small number of channels

Pick the two or three channels most likely to hit the target, and do them properly. A typical starting mix for an SME looks like:

• Google Ads to capture people already searching.
• Meta Ads to reach new people and bring back visitors who didn't convert.
• Social media and SEO to build trust and lower costs over time.

Spreading a small budget thinly across every channel is one of the most common reasons strategies fail.

Step 5: Set the budget from the numbers

Use your target cost per sale or lead to set the budget. If you can afford £50 per lead and need 30 leads, you need around £1,500 a month in media, plus the cost of running it. If that is too much, lower the target or start with the channel most likely to deliver cheaply and build from there.

Keep a small part of the budget for testing new things, so you aren't relying on one channel forever.

Step 6: Review weekly, adjust monthly

Agree a simple weekly report: spend, results, cost per result and what is changing. Review the strategy itself monthly or quarterly, moving budget towards what is working.

The point of the strategy isn't to be right on day one. It is to make better decisions every week because the numbers are visible.

A one-page template

Your strategy should answer these in a page or two:

1. Business target and what it means for marketing.
2. How results will be measured.
3. The channels and why.
4. The monthly budget and target cost per result.
5. What will be tested.
6. How and when results will be reported.

Frequently asked questions

How much should a small business spend on digital marketing?

Work it out from your target cost per sale or lead and the number of customers you need, rather than from a percentage of turnover. That gives you a budget tied to results you can measure.

How long does a digital marketing strategy take to work?

Paid channels such as Google Ads and Meta Ads can produce results within weeks once tracking is right. SEO and social media build more slowly, usually over months.

Do I need a written digital marketing strategy?

Yes, but it can be short. A page or two that sets the target, the measures, the channels, the budget and the reporting rhythm is enough for most small and medium businesses.
