Planning a Digital Marketing Budget Across Channels

Setting a digital marketing budget is one of those jobs that often gets done by copying last year’s figure and adding a little. That approach is easy, but it rarely reflects what the business actually needs or what the data says is working.

This article sets out a practical way to plan a budget across channels. The examples are hypothetical and the figures are illustrative only. Every business is different, so treat them as a way of thinking rather than a recommendation.

Step 1: Work out what you need marketing to deliver

Start from the business target, not the spending. If you know how much revenue you want from new customers, you can work backwards:

1. How many new customers does that revenue require, based on your average order or contract value?
2. What share of enquiries typically become customers?
3. So how many enquiries do you need?
4. Based on past performance, roughly what does an enquiry cost to generate?

A hypothetical example: a service business wants 40 new clients next year. If around one in four qualified enquiries becomes a client, it needs about 160 qualified enquiries. If past campaigns suggest an enquiry costs somewhere around £60 to generate, the working budget for acquisition is in the region of £9,600, before creative, tools and management time.

The numbers will not be precise, especially if you have little historical data. The point is to connect the budget to an outcome so that it can be judged later.

Step 2: Account for the full cost

A budget that only includes ad spend understates the real investment. Include:

• Media spend: money paid directly to platforms such as Google Ads or social networks.
• Content and creative: writing, design, photography and video.
• Tools and software: email platforms, SEO tools, scheduling tools and analytics.
• People: internal time, freelancers and agency fees.
• Website improvements: landing pages, speed work and conversion fixes that make every channel perform better.

Step 3: Split spend by role, not just by channel

It helps to think about what each channel does rather than treating them all as interchangeable. A simple way to group them:

Capturing existing demand

Paid search and SEO reach people who are already looking for what you offer. These channels often produce the most direct results, so they tend to be where a new budget starts.

Creating demand

Social media advertising, content marketing and video reach people who are not searching yet. They build awareness and fill the pipeline for the future, but results are slower and harder to attribute.

Nurturing and retaining

Email marketing and remarketing keep you in front of people who already know you, including past customers. These channels are often inexpensive relative to the value they create.

A hypothetical split for a small business new to digital marketing might put most of the budget into capturing demand, a smaller share into nurturing and a modest amount into creating demand. A more established business with strong search visibility might shift more towards creating demand. There is no correct ratio. The right split depends on your market, your sales cycle and what your data shows.

Step 4: Balance short-term and long-term channels

Paid channels can produce results quickly but stop when spending stops. SEO and content take longer to build but can keep delivering for years. A budget that is entirely paid can leave the business exposed if costs per click rise. A budget that is entirely organic can leave a gap while it builds.

Most businesses benefit from a mix, with paid activity covering the near term while organic foundations are laid.

Step 5: Keep a test budget

Set aside a small portion of the budget for experiments, such as a new platform, a new audience or a new format. Give each test a clear question, a fixed spend and a time limit. If it works, it earns a place in the main budget. If it does not, you have learned something at a known cost.

Step 6: Plan for the calendar

Demand in many sectors rises and falls through the year. Map your budget against seasonal peaks, product launches and events. Spending evenly every month is simple to manage but may mean underspending when customers are most active.

Step 7: Measure properly before you spend

A budget can only be reviewed if results can be measured. Before campaigns start, check that:

• Analytics is set up and key events are tracked accurately
• Campaign links are tagged consistently
• Enquiries and sales can be traced back to a source, including phone calls where possible
• Someone owns the reporting and reviews it regularly

Step 8: Review and reallocate

Review performance monthly and make larger decisions quarterly. Move money towards channels that produce customers at an acceptable cost and away from those that do not. Allow for time lags: a content programme or SEO work will not show its full value in a single month.

A short checklist

• Budget linked to a clear business outcome
• All costs included, not just media spend
• Channels grouped by the job they do
• A mix of short-term and long-term activity
• A defined test budget
• Tracking in place before spending starts
• Regular reviews with room to move money
