The hardest part of a website project is usually not the launch. It is the messy middle.

That point where the initial excitement has worn off, the project is underway, and assumptions that were not dealt with upfront start to surface.

Stakeholders who seemed aligned suddenly have different expectations. Content takes longer than planned. Functionality that sounded simple becomes more complex. Timelines slip. Feedback becomes subjective.

Most of the time, these problems happen because the planning did not go deep enough before the project started.

That is where a strong website brief makes such a difference.

A website brief is not just a document you send to an agency so they can give you a quote. Used properly, it is a planning tool. It helps you clarify what the project needs to achieve, align internal stakeholders, define the scope, highlight risks, and identify what still needs to be explored.

In this post, we will share the Website Brief Framework: a practical way to plan your website project before moving into design and development.

Why Website Projects Get Messy

Most website projects start with good intentions.

There is usually a clear sense that the current website is no longer doing what it needs to do. It might feel outdated, be difficult to manage, underperform commercially, or cause frustration for users and internal teams.

But once the project gets moving, hidden assumptions start to surface.

For example:

“Everyone knows what we’re trying to achieve”
“The content will be ready when we need it”
“That feature should be simple”
“The budget should cover everything”
“We’ll sort the details once the project starts”

Individually, these assumptions may not seem like major issues.

Collectively, they can slow the project down, increase costs, create frustration, and damage the relationship between the organisation and the agency.

A strong website brief helps bring these assumptions into the open before the project begins.

It does not need to remove every unknown. But it should make sure the important questions are being asked early enough.

The Website Brief Framework

A useful website brief should do more than describe the website you want.

It should create clarity across six key areas: Context, Objectives, Audiences, Scope, Constraints, and Decision Process.

Together, these areas help you move from “we need a new website” to a clearer understanding of what the project needs to achieve, who it needs to serve, what it should include, and how decisions will be made.

The framework also helps identify gaps.

That is important because a strong brief does not need to have every answer. But it should make it clear what is known, what is assumed, and what needs further exploration before the project moves forward.

1. Context: Why Is the Project Happening?

Start by helping the agency understand the world around the project.

Explain who you are, what you do, and why the website project is happening now. Has your organisation changed? Are you launching new services? Is the current website difficult to manage? Are users struggling to find what they need? Is the site no longer supporting your commercial or marketing goals?

This section should also include what makes your organisation different, who your competitors are, and any websites you like or dislike.

The aim is not to write pages of background information. It is to give the agency enough context to understand the opportunity, the challenge, and the reason the project matters.

2. Objectives: What Does Success Look Like?

A website project should not only be judged by whether the new site looks better than the old one.

It should be judged by whether it helps the organisation achieve something meaningful.

Your brief should explain what needs to improve and how success will be measured. This might include increasing enquiries, improving conversion rates, reducing support calls, making content easier to manage, improving accessibility, supporting recruitment, or helping users find information more easily.

Try to avoid vague objectives such as “we want a modern, user-friendly website”.

Instead, be more specific:

We want to increase qualified enquiries from our key services
We want to reduce admin by improving online self-service
We want to improve the user journey for people comparing our services
We want internal teams to update content more easily

Clear objectives make better decisions possible later in the project. When opinions differ, you can come back to the question: which option best supports what we are trying to achieve?

3. Audiences: Who Is the Website Really For?

A website brief should not only explain your organisation. It should explain the people the website needs to serve.

Define your primary and secondary audiences, what they need from the website, the questions they are likely to have, and the actions you want them to take.

Different audiences may have different priorities. A first-time visitor may need reassurance and clarity. An existing customer may need fast access to information. A candidate may want to understand your culture. A stakeholder may be looking for evidence of credibility.

If the audience is unclear, the website can quickly become organisation-led rather than user-led. That often leads to navigation, content and messaging that make sense internally, but do not work as well for the people using the site.

4. Scope: What Does the Website Need to Include?

Scope is where you define the shape of the project.

This should include the likely pages, content requirements, key functionality, integrations, automation, CMS requirements, tracking, accessibility needs and any content migration from the existing website.
You may also want to state whether you have a CMS preference or whether you would like the agency to recommend the right platform. If you are unsure, our guide to choosing the right CMS for your website project can help you think through the options.

When listing requirements, also consider whether AI should form part of the scope. For example, could AI-powered search, personalisation, smart recommendations or guided journeys improve the website experience? This does not mean adding AI for the sake of it, but as user expectations change, it is worth considering where AI could genuinely improve clarity, relevance or usability. Our post on how AI is raising the bar for website experience explores this in more detail.

The goal is not to write a full technical specification. It is to give the agency enough information to understand what the project is likely to involve and where more scoping may be needed.

5. Constraints: What Realities Will Shape the Project?

Constraints are not a bad thing. They help shape a more realistic project.

Your brief should be clear about budget, timeline, internal resources, approval processes, compliance requirements and any non-negotiables.
Budget is especially important. Some organisations avoid sharing a budget because they worry the agency will simply quote up to that number. But without some indication of investment level, it is much harder to recommend the right approach.

A limited budget might mean prioritising the essentials first. A larger budget might allow more time for discovery, UX, content, integrations, personalisation or conversion improvement.

This is also where marketing teams may need to frame the website as an investment, not just a cost. If you need help making that case internally, our blog on how to communicate the value of marketing internally may be useful.

The clearer you are about the realities around the project, the easier it is for agencies to recommend something that is ambitious but still achievable.

6. Decision Process: What Happens Next?

A strong brief should also explain how the project will move forward.

Include who the main contacts are, who will be involved in decisions, how proposals will be assessed, what agencies should return, and the key dates for the selection process.

For example, you might ask agencies to provide:

A recommended approach
Relevant case studies
A proposed timeline
A clear breakdown of costs
Initial observations or recommendations based on the brief

This helps agencies respond in the right way. It also makes it easier for you to compare proposals fairly, because everyone is working from the same expectations.

Without a clear decision process, agency selection can become subjective, slow and difficult to manage. A good brief should make the next step obvious.

Where Does Discovery Fit?

A website brief should help you understand whether you are ready to move straight into the main project or whether a discovery phase is needed first.

Discovery is especially useful when there are multiple stakeholders, complex user journeys, unclear content requirements, integrations, technical considerations, or uncertainty around scope and budget.

The purpose of discovery is to work through these questions before design and development begin. It can help define user journeys, sitemap, content structure, functionality, integrations, success measures and project risks.
This is not about slowing the project down. It is about reducing uncertainty before the more expensive work begins.

If you are unsure whether discovery should be part of your planning, our blog on discovery workshops that de-risk health sector website projects explains how this kind of planning can reduce risk before a website project starts.

Common Website Brief Mistakes to Avoid

Even with the right structure, there are a few common mistakes that can weaken a brief.

One is focusing on features before objectives. A list of functionality is useful, but only if the agency understands what the website needs to achieve.

Another is underestimating content. Content is often one of the biggest causes of delay, especially when it needs to be written, approved, restructured or migrated.

Budget and timeline are also easy to avoid, but they should be addressed clearly. Agencies need to understand the realities around the project in order to recommend the right approach.

Finally, avoid leaving too much open to interpretation. You do not need to answer everything, but you should be clear about what is known, what is assumed, and what still needs to be explored.

A Simple Test Before You Send the Brief

Before sharing your brief with agencies, ask yourself:

Would an agency understand why this project matters?
Is it clear what success looks like?
Have we explained the audiences and key user journeys?
Is the scope clear enough for an agency to respond properly?
Have we been honest about the budget, timeline and internal resources?
Does the brief highlight what still needs exploring?

If the answer to any of these is unclear, the brief probably needs more work before it goes out.

That does not mean delaying the project unnecessarily. It means giving the project a stronger foundation before important decisions are made.

Plan Your Website Project With More Confidence

A strong website brief will not guarantee a perfect project, but it will give the project a much better starting point.

It helps you clarify what you know, what you are assuming, what still needs exploring, who needs to be involved, and what should happen next.

FAQs About Writing a Website Brief

What is a website brief?

AI is changing website experience by raising expectations for speed, relevance and ease. Users are increasingly used to asking natural questions, receiving concise answers and being guided to useful information quickly. A website now needs to feel clear, helpful and effortless, not just visually polished or technically sound.

Why is a website brief important?

A strong website brief reduces misunderstanding, aligns stakeholders, clarifies priorities and helps avoid costly changes later in the project. It gives everyone a shared starting point before design and development begin.

Who should write the website brief?

The brief should usually be led by the project owner or marketing lead, with input from key stakeholders. It should not sit solely with procurement, as the brief needs to reflect the organisation’s objectives, audience needs and practical requirements.

What should be included in a website brief?

A good website brief should cover context, objectives, audiences, scope, constraints and decision process. This includes details such as current website issues, success measures, content requirements, functionality, integrations, budget, timeline and internal approvals.
