Website Design Brief: What to Include and How to Write One

If you are planning a new website, the quality of your brief can shape the whole project. A strong website design brief helps your agency or designer understand your business, your audience and what the website needs to achieve. It gives the project direction from the start. It reduces guesswork, avoids wasted time and helps you make better decisions about content, functionality and budget.

A website design brief is a document that explains the purpose of the website, the audience it serves, the content it needs and the functionality it should include.

Many businesses begin in the wrong place. They focus on colours, layouts and visual style before they have properly defined the purpose of the site. They assume search engine optimisation (SEO) can be bolted on at the end. They underestimate how much content is needed. Or they expect an agency to understand their business without being properly briefed.

That usually leads to a slower project and a weaker result.

A good website is not just a design exercise. It is a business tool. And a well-thought-out website design brief can make the difference between a website that simply looks good and one that works hard for your business.

TL;DR (Too Long; Didn't Read)

• A website design brief explains what your website needs to achieve, who it is for and how it should work.
• A strong brief should cover your business goals, target audience, content plan, functionality and marketing priorities.
• Planning content and SEO early will make the website more effective and easier to grow.
• The more clearly you explain your business and objectives, the better advice a web design agency can give.

In simple terms, writing a website design brief usually involves five steps:

• Defining your business goals
• Understanding your target audience
• Planning the structure and content of the site
• Identifying the features and integrations the site needs
• Agreeing the timeline and budget for the project

What is a website design brief?

A website design brief is a document that explains what your website needs to do, who it is for and what success should look like.

It does not need to be long or overly technical. But it does need to be clear. A useful website brief gives your agency enough information to recommend the right structure, content, functionality and process.

At a minimum, it should cover your business, your audience, your goals, your content needs, your preferred features, your timescales and your budget. It should also explain any constraints, such as internal approvals, existing systems it needs to work with or brand guidelines.

The purpose of the brief is not to solve every detail before the project starts. It is to give the project a solid foundation.

Why a good website brief matters

A weak brief creates problems early.

If your objectives are unclear, the agency has to make assumptions. If your audience is vague, the messaging will be vague too. If the content has not been thought through, the sitemap and design are likely to need change later. If SEO is left until the end, important opportunities can be missed before the site even launches.

SEO plays an important role because it helps your website appear in search results when potential customers are looking for the products or services you offer. Good SEO is not just about technical tweaks. It often starts with the way a website is structured, the topics each page covers and the language used in the content.

A clear website design brief helps in several ways.

First, it aligns everyone involved in the project.

Second, it improves the quality of the agency’s response.

Third, it helps with planning.

A website project involves more than design and development. Content writing, photography, video, approvals, testing and proofing all take time. A proper brief helps reveal what is involved.

And lastly, it leads to a better website. Not just a better looking one, but one that is more useful to your customers and more effective for your business.

 

How to write a website design brief

Start with your business

Before you think about design, think about what the business actually needs from the website.

Do you want more enquiries? Better quality leads? More online sales? Better support for your sales team? Improved credibility? A clearer explanation of your services? Recruitment support?

The website should support real business goals, not vague ambitions.

It helps to be specific. Saying “we want a more modern website” is not really a goal. Saying “we want the site to generate more enquiries for our commercial landscaping service” is much more useful.

Define your audience clearly

A good website is built around the people using it.

Your website brief should explain who your main audiences are and what they need from the site. That means thinking about their questions, concerns and priorities, not just your own.

This influences the site structure, the page content and the calls to action.

Explain your products or services properly

Do not assume the agency will automatically understand the nuances of your business and market.

A website design brief should include a clear overview of what you offer and how you want to position it.

This often links closely to your wider brand positioning and messaging, which should be reflected consistently across the website.

Research your competitors

Competitor research helps you identify patterns, gaps and opportunities.

Look at how others structure their services, how they build trust, and how clearly they explain what they do.

 

Plan your content early

Content is often one of the most underestimated parts of a website project.

Many businesses think the hard work is the design and development. In reality, content often takes the most thought and effort.

If you are unsure how to approach this, our guide on How to write website content that ranks in Google explains how content, structure and search intent work together.

A good web design agency can help define the content structure, identify gaps and recommend the right level of detail.

Strong content may include service pages, case studies, FAQs, articles, testimonials and other forms of social proof that build trust.

Many website delays happen because content has not been planned early enough. Writing, photography and video all need time, budget and ownership.

 

Think about SEO from the start

SEO should shape the plan, not just polish the finished site.

The best SEO decisions are made early, when the site structure and content plan are being defined.

That is why SEO should be considered when writing the brief.

 

Consider the features and functionality you actually need

Not every website needs complex tools, but the right features can make a big difference.

This might include e-commerce, booking systems, CRM integration, resource libraries, customer portals or automation tools.

Features should support real business needs, not just fill a wishlist.

 

Understand the typical website process

A well run project usually follows a clear process. At The Visual Works, our website development approach is built around discovery, content planning and structured design to ensure each stage supports the next.

Clear planning at the start makes every later stage smoother.

What to include in a website brief

• A short overview of your business
• A description of your target audiences
• The main goals of the project
• A summary of competitors
• The sections or pages required
• Content requirements
• Required functionality
• Design direction
• Timeline and budget
• Marketing priorities

Common mistakes when writing a website brief

• Focusing on design too early
• Underestimating content
• Treating SEO as an afterthought
• Assuming the agency understands your business
• Being too vague about functionality
• Expecting features that were never specified

A better brief leads to a better website

A clear brief helps your agency understand what the website needs to achieve and gives the project a much better chance of success.

Once your brief is ready, choosing the right web design agency becomes much easier.

Look for an agency that understands your project, asks good questions and demonstrates relevant experience.
