Strategy
Outsource your social media agencies strategy or keep it in house?
How UK marketing leads should plan social media agencies strategy, covering objectives, budget, procurement, data protection and questions to ask before signing.
What to take away
- Keep strategy in house when you employ one experienced social manager, and buy execution. Outsource the whole function only when no internal capability exists.
- Build the budget from a commercial target, then split media, production and management in writing.
- Six months with a review at month three, plus 30 days' notice, limits a poor fit.
- You stay the data controller, so a written processing agreement comes first.
- Put the 90-day review and the quarterly strategy review in the contract, with named owners.
Where social strategy should sit
For most marketing leads in England, one capable in-house manager is enough to keep strategy, while the agency supplies production, paid media and reporting. Outsource strategy too only when nobody internal can set it.
A retainer is a delivery mechanism, not a plan. If you cannot state what the business must change by December 2027, no agency can price the work honestly.
Strategy splits into three layers. The business layer sets the commercial target and the constraint. Audience evidence decides who you reach. Delivery covers channels, formats, cadence and production.
Agencies can argue with delivery. They should not argue with the commercial target.
Comparing full-service, specialist and hybrid delivery
Comparing delivery models
What you buy
- Full service
- Strategy, creative, media and community management from one agency
- Specialist
- Paid media, content and community management from separate suppliers
- Hybrid
- Strategy in house, execution bought where it is cheapest
Main risk
- Full service
- A change of account team breaks continuity
- Specialist
- You coordinate suppliers, which costs staff time
- Hybrid
- You act as account director and need clearer governance
Full service suits teams with no in-house social capability. Specialist suppliers give more depth per discipline, while hybrid keeps strategy in house and buys execution outside.
Record the reasoning for your chosen model, and do not revisit it every quarter. The social media agencies strategy framework sets out the questions to work through first.
Budget, fees and contract terms
- Write the commercial target, such as 120 qualified leads a month.
- Estimate the media spend required at a realistic cost per result.
- Add production costs for the asset volume each channel needs.
- Add the management fee as a fixed retainer tied to a scope of work.
- Compare the total with the budget, and change the target if it does not fit.
Bottom-up budget build
- Start with commercial target
- Estimate leads or sales needed
- Work back to media spend
- Add production and management
- If over budget, change target
A percentage-of-media-spend fee rewards the agency for spending more, which may not match your interests. A fixed retainer tied to a scope of work is easier to audit.
Where paid media features in the plan, the Google Ads best practices guidance is a fair benchmark for judging a proposed account structure.
The social media agencies budget template lists the eight lines a workable budget needs.
Example: reading an illustrative retainer
Illustrative split only, not a market rate: £6,000 media, £900 management at 15% of media spend, £1,100 production, £8,000 total per month.
A single figure hides which part is media and which is fee. A split quote shows how much of the budget reaches the audience.
State the fee as a percentage or a fixed sum, then apply that rate to your own media plan.
Procurement, data protection and review dates
- Issue a written brief and score no more than four proposals on the same criteria.
- Name the people who will work on the account and ask how many clients each serves.
- Take two references from similar-sized clients in your sector, and call them.
- Check that professional indemnity cover is current and that Companies House records look consistent.
Add a small paid discovery task. It shows how each agency thinks rather than how it presents.
Briefs that make price claims or use testimonials must satisfy the Advertising Standards Authority codes.
The social media agencies commercial contracts checklist covers the clauses to insist on before signature.
Where the agency handles customer data, you remain the controller and it becomes the processor. Settle purpose, retention and subject access handling against the ICO GDPR guide for organisations before work starts.
Fix a monthly report and a quarterly strategy review in the contract. A 90-day review gives early signal while correction is still cheap.
Common questions
Should social strategy sit with the agency or in house?
Keep it in house when one experienced social manager can set the commercial target. Buy execution from the agency.
How long should the contract run and what notice is fair?
Twelve months is common. A six-month initial term with a review at month three is safer, and 30 days' notice is reasonable.
How should media, production and management be split?
Work back from the commercial target to the media spend needed, then add production and a management fee. State the fee as a fixed retainer or a percentage of media.
What checks come before signing?
Scored proposals, named account staff, two references and a written data processing agreement.
