Content agencies: six strategy mistakes to catch early

What to take away

A marketing lead in England with a signed retainer and no agreed measure is the scenario behind this list.
A strategy mistake is any choice that spends money or creates legal risk before useful content exists.
Criteriait must affect budget, reporting or compliance, and be fixable before a contract starts.

How the six mistakes were selected

These are choices made before and during an engagement, not judgements about a supplier. Each leaves a trace in budget, reporting or compliance.

Geography is England-first. Equality and direct marketing rules apply across the whole United Kingdom; devolved procurement routes vary in Scotland, Wales and Northern Ireland.

Use this sequence to work through objectives, choices and reviews before committing to an agency.

Mistake 1: briefing an agency before the outcome is clear

A brief that lists tone, channels and posting frequency but no result is a shopping list. Agencies price the list they are given.

Shopping list vs measurable outcome

Shopping list brief

Content: Tone, channels, frequency
Agency response: Prices the list
Example: £3,000 a month
Progress check: Volume only

Outcome brief

Content: One measurable result
Agency response: Proposes the route
Example: Qualified enquiries a month
Progress check: Agreed measure

Name one measurable outcome, such as qualified enquiries a month or repeat questions deflected, then let the agency propose the route.

Illustrative example: a team paying £3,000 a month with no agreed measure cannot tell progress from volume.

Mistake 2: treating a channel plan as a strategy

A strategy names the audience, the problem, the outcome and the constraints. A channel plan names where the work appears.

Is it a strategy or a schedule?

Does your only document list formats and cadence?

Yes

You have bought a schedule, not a strategy

Ask what survives if the main channel closed

If your only document lists formats and cadence, you have bought a schedule.

Ask what it would still achieve if the main channel closed. A blank answer means the plan is the strategy.

Mistake 3: skipping the lawful basis for direct marketing

Email and SMS direct marketing are subject to the Privacy and Electronic Communications Regulations 2003 (PECR), alongside data-protection law. Some retargeting also involves personal data and may engage data-protection rules.

The ICO's Direct marketing guidance explains how to assess PECR and data-protection requirements; a lawful basis such as legitimate interests does not replace consent where PECR requires it.

Agencies often draft the copy and the list logic. If the contract is silent on who owns that decision, you own the risk.

Mistake 4: setting targets with no baseline or review date

A target with no starting number cannot be met or missed, which is why this one survives longest.

The Government Service Manual guidance on measuring success treats performance measures as something you design, not something inherited at the end of a quarter.

Choosing a baseline you can defend

Pick a number you already record, such as enquiries, demo requests or hours spent on repeat questions. Gather twelve weeks of it before the agency starts.

An agreed gap beats a fabricated one.

Agreeing the review cadence

Set review points at 30, 60 and 90 days, each ending in a written decision: continue, change the mix, or stop.

Cadence protects budget better than a weekly report.

Mistake 5: overlooking equality and accessibility duties

The Equality Act 2010 requires service providers to make reasonable adjustments for disabled people; employers also have duties. For content teams, consider accessible formats and inclusive language before publication.

Discuss image descriptions and agree a sign-off step to check content for accessibility barriers before publication.

Mistake 6: writing a contract around activity

Deliverable counts are easy to compare and easy to buy. They also reward volume over judgement.

Write the contract around decisions: what the agency decides, what you approve, who owns the assets, and what happens if the outcome misses. Define included work and a written change-control route for out-of-scope requests; state renewal, notice, exit and asset-handover terms, and link performance reviews to the agreed outcome.

Use the review points to sequence briefs, approvals and decisions once month one is agreed.

Glossary

Brief: the written statement of outcome, audience and constraints.
Baseline: the measured starting point for a target.
Lawful basis: the data protection ground relied on for direct marketing.
Review point: a dated decision to continue, change or stop.

Common questions

Does a strategy need SEO?

Only where search demand is part of how your audience finds you. It is a channel choice inside the strategy, not the strategy itself.

Can a small team run this without an agency?

Yes. The criteria and the review cadence stay the same. An agency adds capacity and craft, not the objective.

What if the outcome changes mid-contract?

Raise it at the next review point. Changing it once, in writing, is normal. Changing it monthly means the brief was never finished.
