A small UK business might plan from roughly £1,000–£3,000 per month for a focused retained marketing service, while a broader programme involving strategy, frequent original content, several channels, paid-media management and detailed reporting can require £3,000–£10,000 or more per month. Advertising spend, major production, website work and specialist tools may be separate. These are planning estimates only; every business needs a scoped quote based on goals, channels, volume, complexity and internal contribution.
Do not buy a number of posts in isolation. Buy an accountable plan connecting audience, message, distribution, response handling and measurement.
What are you trying to achieve?
Choose one primary commercial objective for the next planning period: qualified enquiries, online sales, event attendance, recruitment, retention or awareness in a defined audience. Different goals require different channels and evidence.
Describe the audience using buying situation and needs, not only age or job title. What triggers action? Who influences the decision? What evidence reduces risk? What prevents conversion after someone clicks?
Set a baseline before work begins. Record current lead sources, conversion definitions, average sales cycle and known data gaps. Avoid promising exact revenue from channels where tracking is partial or the sale occurs offline.
What do common service levels include?
A light-touch arrangement may cover one or two channels, a monthly content plan, supplied assets, scheduling, basic community handling and a short report. It suits a business with a clear proposition and staff who can provide expertise quickly.
A mid-level programme may add channel strategy, original copy and design, regular video editing, campaign planning, paid-media management, landing-page advice and deeper optimisation. A comprehensive programme may involve research, photography or video production, several specialists, conversion work, marketing automation and executive reporting.
Price depends on output and responsibility. Four expert interviews turned into useful content may be more valuable and labour-intensive than twenty generic posts. Ask how research, approvals, revisions and comments are handled.
How should you budget for paid media?
Separate media spend from management fees and creative production. Media spend goes to the platform; management covers setup, targeting, testing, monitoring and reporting. Creative covers copy, design, photography, video or landing pages.
An early test budget must be large enough to produce useful evidence for the audience and sales cycle, but there is no universal minimum. The supplier should explain the assumptions behind its recommendation, likely learning period and stop conditions. Treat forecasts as scenarios, not guarantees.
Confirm who owns advertising accounts, pixels, audiences, creative files and historic data. Your organisation should normally retain administrative control and grant the supplier appropriate access. Set spending limits and require approval for material changes.
Which variables move the cost?
The main variables are channel count, publishing frequency, format, research depth, on-location production, community-management hours, response expectations, paid-campaign complexity, languages, regulated claims, stakeholder approvals and reporting.
Hidden effort often appears in:
- Chasing internal experts and approvals
- Reworking weak source material
- Moderating evenings or weekends
- Producing accessible captions and transcripts
- Adapting creative for several placements
- Building landing pages and tracking
- Cleaning CRM data
- Responding to sensitive complaints
Decide what your team will supply and by when. A lower retainer that assumes finished photography and same-day approvals is not comparable with a full-service proposal.
What legal and platform responsibilities matter?
Marketing claims should be truthful, clear and capable of substantiation. The CMA Green Claims Code is relevant to environmental claims, while the CMA’s online reviews guidance addresses reviews and endorsements. Sector-specific advertising rules may also apply.
Paid, gifted or otherwise incentivised endorsements must be appropriately disclosed. Do not ask a supplier to manufacture reviews, conceal sponsorship or imitate customers.
Direct marketing and tracking can involve UK GDPR and the Privacy and Electronic Communications Regulations. The ICO direct marketing guidance explains responsibilities across email, messages and online advertising. Obtain advice for your campaign and technology rather than copying another site’s consent setup.
What should good reporting contain?
A useful report answers what happened, why it may have happened, what was learned and what changes next. It distinguishes platform-reported results from verified business outcomes and notes tracking limitations.
Agree a small measurement hierarchy:
- Business outcomes, such as accepted leads or sales
- Conversion actions, such as completed forms or calls
- Quality indicators, such as landing-page engagement
- Distribution indicators, such as reach or impressions
Follower count and engagement rate can provide context but should not replace commercial measures. Avoid combining unlike platform metrics into a misleading total.
Where feasible, use consistent campaign naming, CRM source capture and call tracking with suitable privacy controls. Review lead quality with sales staff, because an advertising platform cannot know whether an enquiry became a suitable opportunity unless reliable data is returned.
How do you compare suppliers?
Ask each supplier to respond to the same brief and budget context. Look for clear choices and exclusions. A proposal listing every channel without prioritisation is not necessarily comprehensive; it may be unfocused.
Request examples of process and reporting, not confidential client data or unverified performance claims. Meet the people who will do the work. Clarify whether senior staff shown during the pitch remain involved.
Supplier checklist
- Connects channel choices to a defined audience and goal
- States monthly deliverables and responsibilities
- Separates retainer, media, production and software costs
- Explains assumptions behind forecasts
- Gives your business account ownership and access
- Defines approval and escalation workflows
- Describes comment and complaint handling
- Understands disclosure, privacy and claim substantiation
- Reports lead quality and limitations
- Includes notice periods and handover deliverables
How can you control spend without reducing quality?
Narrow the audience and channel mix. Build one strong source asset, such as an expert guide or customer interview, then adapt it honestly for suitable formats. Batch approvals and production. Give the supplier prompt access to subject experts.
Use a three-month test plan with hypotheses and decision points, while recognising longer sales cycles. Stop low-value activity rather than adding channels. Preserve a small experimentation allowance so every pound is not committed to repeating last month.
Do not cut accessibility. Captions, readable contrast, alt text and clear landing pages improve access and reduce avoidable friction. WCAG 2.2 provides the core web accessibility standard.
Frequently asked questions
Is advertising spend included in an agency retainer?
Often it is separate, but contracts vary. Ask for a line-by-line view of media, management, creative, tools and VAT.
How many social posts should we publish?
There is no universal number. Choose a sustainable frequency that supports useful content and timely responses on the channels your audience actually uses.
Should a small business use every platform?
Usually not. Start where customers research, discuss or buy, and where your team can maintain quality. Expand only with a reason and capacity.
Can an agency guarantee leads?
It can commit to work, controls and optimisation, but cannot guarantee customer behaviour. Require transparent assumptions, measures and stop conditions.
