Why content strategy needs a longer view now

A content strategy should start with a business problem, yet most buyers approach content agencies with a production problem. They have a backlog, a launch or a quarterly target, and they want words and images delivered on time. That framing produces short contracts, thin briefs and agencies that never learn enough about the business to improve anything.

A strategy-led buying decision starts somewhere else. It asks what the content is meant to change, who inside the business will own that change, and what evidence would show it worked. Those three answers shape the agency model far more than headcount or day rates do.

Planning horizons have also stretched. Search behaviour, AI summaries and social distribution all move faster than a twelve-month retainer assumes, so the plan needs review points built in rather than a single annual reset. A written strategy gives you a reference point when the channel mix shifts mid-year.

If you are rebuilding a plan from scratch, read this strategy framework before writing the brief: it separates commercial objectives from channel tactics.

What should the brief commit to before you contact anyone?

The outcome should be a business result rather than a content output. "Increase qualified enquiries from organic search by 20 per cent" is scoreable. "Publish twelve blog posts a quarter" is not, because it says nothing about whether the work mattered.

The baseline is the current number you are trying to move, stated with its source and date. Without it, no agency can tell you whether the target is ambitious or trivial, and you cannot judge performance later.

The constraint covers budget range, approval process and any legal or brand limits. The deadline sets the review point. For example, a team with a £60,000 annual content budget might split it as £36,000 for production, £12,000 for distribution and £12,000 for measurement and tooling, then ask agencies to respond to that split rather than invent their own.

Write the brief before you shortlist. Agencies that receive a vague brief will price the ambiguity into the fee.

Which agency model fits your capability gap?

There are three broad models, and they are not interchangeable.

Capacity. You have a strategy and an in-house lead, but not enough hands. You are buying execution against a plan you already own. Fees are usually output-based, and the risk is that quality drifts when volume rises.

Capability. You lack a skill such as technical SEO, video production or editorial governance. You are buying expertise that should transfer to your team over time. Ask how the transfer happens, and put it in the contract as a deliverable.

Accountability. You want an agency to own a channel or a number. This is the most expensive model and the one most often mis-sold, because accountability requires access to analytics, sales data and decision-makers. If you cannot give that access, do not buy this model.

Most mid-sized organisations end up with a blend. The useful discipline is naming which parts of the programme sit in each model, so nobody assumes the agency is responsible for something it was never given.

Once the model is agreed, use this planning template to create a working document your team and the agency can both update.

How should you structure the first ninety days?

A new agency relationship usually fails in the first quarter, not the second year. The failure mode is a slow start followed by a scramble to show output before the first review.

This sequencing matters because it exposes problems while the contract is still flexible. If approvals take ten days instead of two, you want to discover that in month one rather than during a campaign launch.

Set the ninety-day plan with named owners on both sides and a single weekly check-in. This ninety-day plan sets out the milestones and evidence to collect at each review point.

Where does distribution fit in the plan?

Distribution is where most content budgets quietly leak. Production is planned in detail, then publishing happens and nobody owns promotion beyond a social post.

Paid support for content works best when the creative is built for the placement rather than repurposed at the end. The IAB UK native distribution principles set out creative and labelling expectations for sponsored content, and they are a sensible reference when briefing native placements with a publisher.

Platform-native formats have their own conventions. LinkedIn sponsored content, for example, performs differently from a display placement and needs its own copy, cadence and landing experience, so treat it as a separate channel with its own budget line.

If paid search supports your content, the account structure and quality score rules matter as much as the landing page. Google Ads best practices explain how ad relevance and landing page experience feed into cost, which is useful when you are arguing for a bigger share of budget.

Whichever mix you choose, agree who pays for distribution, who reports on it and what counts as a reasonable cost per engaged session. There is no universal cost-per-engaged-session figure: agree how an engaged session is defined, then compare results with your own baseline and target.

How do you score and compare agencies fairly?

Use one rubric for every shortlisted agency, score before discussion, and keep the completed sheets. The weighting should reflect your brief, not a generic template.

The table below is an illustrative example for a buyer whose priority is accountability rather than volume.

Accessibility belongs in the rubric because it affects cost and reach. The W3C accessibility fundamentals overview is a practical starting point for the checks a content team should build into production, and agencies that already work this way tend to be better organised elsewhere too. If you need a testable acceptance criterion, name WCAG 2.2 Level AA in the brief and require evidence against that target.

Score independently, then meet. Averages hide disagreement, and the disagreement is usually the useful part.

What should the contract and governance cover?

Contracts fail on the things nobody wrote down. Before signing, confirm in the written agreement who owns the content, what happens to work in progress if the relationship ends, and how fees change if scope moves. Define the handover and change-control process rather than relying on an informal understanding.

Ask for the named lead in writing, with an estimated share of their time. Agency pitches often feature senior people who are not on the account after month two, and a named-lead clause is the simplest protection.

Agree the reporting pack in advance: which metrics, from which sources, at what frequency. If the agency cannot access your analytics, say so and adjust the targets rather than pretending the numbers will appear.

Finally, set a review rhythm. A quarterly commercial review and a monthly delivery review are enough for most programmes. Keep them separate so delivery problems do not crowd out the budget conversation, and so the budget conversation does not hide delivery problems.

How should you build a content budget?

Build the budget from the plan rather than from last year's invoice. Start with the outcomes you committed to, then cost the work needed to reach them, then add the tools and distribution that make the work visible.

Three lines are commonly underfunded. Measurement, because nobody enjoys paying for dashboards. Refresh and maintenance, because published content decays. Training, because in-house teams lose skills when they stop practising them. The CIM strategy and planning training courses are one route to keeping internal capability current if you are bringing more work back in-house.

Set a contingency of roughly ten per cent for testing new formats. A plan with no test budget tends to spend its innovation money on rescuing underperforming channels instead.

Which mistakes should you plan around?

Most agency relationships do not fail because of bad work. They fail because of unclear ownership, slow approvals and targets that were never agreed.

Three patterns recur. The first is buying production when the real gap is strategy, which produces plenty of content and no direction. The second is briefing a channel rather than an outcome, so the agency optimises for the channel and the business number stays flat. The third is skipping the handover, so knowledge leaves with the account team.

Review these common strategy mistakes before shortlisting; doing so can save a procurement cycle, particularly if your last agency relationship ended abruptly.

Write down which of these risks applies to you, and add a mitigation to the brief. A named approver and a two-day approval service level solve more problems than any change of supplier.

How does strategy connect to day-to-day delivery?

A strategy that cannot be delivered is a document, not a plan. The bridge is an operating model: who briefs, who reviews, who publishes, and how work moves between them.

Define the workflow in stages with owners and turnaround times. Keep the number of approval layers to two wherever possible, because each additional layer adds delay without adding judgement. Track cycle time as a metric in its own right, since slow delivery is usually a process problem rather than a creative one.

Capacity planning follows from the same model. If you know the average cycle time and the volume the plan requires, you can see whether the team is over-committed before the quarter starts rather than three weeks in.

Common questions

How long should a content agency contract run?

Twelve months is common, but the first quarter should be a defined test phase with its own review. If the test phase fails, you want a clear exit rather than eleven months of obligation. Longer terms are reasonable when the agency is building something that takes time to mature, such as a technical content programme.

Should we hire in-house or use an agency?

Hire in-house for judgement that must stay close to the business: positioning, subject expertise and final approval. Use an agency for elastic capacity and specialist skills you cannot justify hiring permanently. Most mid-sized teams run both, with a clear split written into the brief.

What should we measure in the first six months?

Measure leading indicators early: publish cycle time, approval turnaround, search visibility and engaged sessions. Commercial outcomes such as enquiries or pipeline usually lag by two or more quarters, so report them alongside the leading measures rather than instead of them.

How do we handle accessibility requirements in the brief?

State the standard you expect, ask for the checks the agency runs and require evidence at handover. Put accessibility in the scoring rubric so it is assessed before contract, not raised as a correction afterwards. It is cheaper to build in than to retrofit.
