A marketing plan is a written document that sets out what marketing a business will do over a set period, usually a year, to reach specific goals. It covers the audience, the activities, the budget, who does what and when, and how success will be measured. It is the working programme that turns a marketing strategy into weeks and pounds.
How a marketing plan works
A useful plan answers six questions, in this order:
- Where are we now? Current sales, leads and costs by channel, plus what competitors are doing. A SWOT analysis is a common way to summarise this.
- Where do we want to be? Two to four goals with numbers and dates, such as qualified enquiries per month or online revenue for the year.
- Who are we trying to reach? The target customers and what they need to hear before they buy.
- What will we do? The channels and campaigns, month by month, with the reason for each.
- What will it cost? Budget by channel and quarter, including agency, freelance and software costs, with VAT treated the same way throughout.
- How will we know? The key performance indicators, how each is tracked and when they are reviewed.
For a small UK business this can fit on a few pages. A bakery with two shops in Bristol might plan a Google Business Profile refresh in January, Mother’s Day and Easter pre-order campaigns in spring, a wedding cake push for summer and a Christmas order deadline campaign, each with a budget and a target.
Why it matters
Without a plan, marketing turns reactive: an ad campaign because a sales rep called, a new website because a competitor launched one, a burst of social posts when sales dip. Each decision may be sensible on its own, but they rarely add up, and nobody can say afterwards what worked.
A plan also makes trade-offs visible. Once the budget is written down by channel, adding something new means taking money from somewhere else, which forces the conversation that ought to happen. It gives anyone you hire a clear brief and a fair standard to be judged against.
Timing is a strong UK-specific reason to plan ahead. Peaks such as January for gyms and for accountants before the 31 January Self Assessment deadline, or late summer for schools and training providers, need content and campaigns built weeks before the demand arrives. Seasonality is easy to miss when you plan one month at a time.
Common mistakes
- Writing a list of activities with no goals, so there is no way to judge them.
- Setting goals the tracking cannot measure, such as leads by channel when phone calls are not recorded at all.
- Copying last year’s plan and adding a percentage to every line.
- Planning every month in fine detail and leaving no budget to back what turns out to work.
- Filing the plan away once it is approved instead of reviewing it every quarter.
How to act on it
Start with last year’s numbers, even rough ones: what you spent, where enquiries came from and what they were worth. Set your goals, then work backwards to the activity and budget each one needs. Keep part of the budget unallocated for tests and for doubling down on what performs.
Book the quarterly reviews into the calendar on the day the plan is agreed. At each one, compare results with the plan, move budget towards what is working and write down why. If you would like a second pair of eyes on a draft, building and pressure-testing plans is a core part of my digital marketing strategy and consulting service.
