How to Write a Website Project Brief

By Alpha Expansion8 minute readReviewed October 2026
The short answer

A website project brief is a short document that tells a design and development company what the site is for, who it serves, what it must include and how you will judge success. Keep it to two or three pages, write in plain language, and be open about constraints, budget range and how the decision will be made.

Key points
  • 01Describe the outcomes you need, not the page layouts you imagine
  • 02State constraints and a budget range openly
  • 03Say who decides and how proposals will be judged
01

What a brief is for

A brief does three jobs. It makes your own team agree on what the project is before anyone outside is involved. It lets several companies respond to the same request, so their proposals can be compared. And it becomes the reference everyone returns to when a question of scope comes up later.

It is not a specification. You are describing the problem and the conditions, and leaving room for the company to propose how to solve it. If you dictate the solution, you pay for a team of experts and use them as typists.

02

The ten sections of a useful brief

SectionWhat to writeCommon mistake
BackgroundWhat your organization does, who it serves and why the project is happening nowA company history nobody needs in order to quote
Goals and measuresThe outcomes the site must produce and how each will be measuredGoals such as modern or fresh, which cannot be tested
AudienceThe main groups of visitors and what each needs to do or findDescribing everyone, which helps design for no one
Content and pagesThe page types you expect, what exists today and who will write what is missingAssuming the content will appear by itself
Functions and integrationsForms, search, booking, payments, accounts, languages and the systems to connectNaming a tool without saying what it must do
Design directionBrand assets, sites you admire and why, and anything to avoidA list of links with no explanation of what you like in them
Technical constraintsCurrent platform, hosting, domains, security or accessibility requirementsMandating a technology without giving the reason
Budget and timingA budget range, fixed dates such as an event or a campaign, and how flexible each isHiding the budget and receiving proposals you cannot compare
Selection processHow many companies are invited, what you want back, the criteria and the datesNo criteria, so the lowest price wins by default
ContactsWho answers questions, who decides and who signsA committee with no single point of contact
03

Write goals a company can design for

The goals section decides the quality of every proposal you receive. A usable goal names a change you want to see and a way to observe it. Compare the two columns below.

Vague goalUsable goalHow you would check it
A modern websiteA first-time visitor understands what we sell and to whom from the first screenShort tests with people who do not know the company
More leadsA larger share of visitors to service pages request a quoteForm submissions divided by visits, in analytics
Better SEOExisting search traffic is kept through the move, and each service has its own pageSearch Console before and after launch
Easy to updateOur marketing coordinator can publish a case study without a developerThey do it in training, unaided
Works on mobileEvery task a visitor can do on a laptop can be done on a phone with one handTesting on real phones before launch

Three to five goals are enough. Put them in order. When two goals conflict during the project, the order tells the team which one wins.

A website brief template you can copy

Copy the outline, answer each prompt in a sentence or two, and delete what does not apply. Most finished briefs fit on two or three pages.

A worked example

Here is how the key parts of the template might read for a dental group with three clinics. Notice that each answer is short and none of them describes a layout.

Illustrative example

Brief for a three-clinic dental group

The organization and its details are invented to show the level of detail that works.

  • BackgroundWe run three clinics in one city. Our site was built for one clinic and patients now call the wrong location. We are opening a fourth clinic next year.
  • Goal 1A patient can find the nearest clinic and book an appointment without phoning. Measured by online bookings as a share of all bookings.
  • Goal 2Each treatment has a page that answers the questions our reception team hears most. Measured by search visits to treatment pages.
  • AudienceNew patients comparing clinics, existing patients booking or changing a visit, and dentists considering a job with us.
  • FunctionsBooking connected to our practice system, a clinic finder, forms for new patients, English and Arabic.
  • ConstraintsPatient data must stay in the practice system. Reception staff will update opening hours and team pages themselves.
  • Budget and timingA range is stated in the full brief. The site must be live before the fourth clinic opens.
  • SelectionThree companies invited. We will score relevant work, approach to booking, content plan, ownership and cost, in that order.

With a page like this, every company quotes for the same project, and the differences between proposals are differences of approach rather than guesses about scope.

06

What to include and what to leave out

Include

  • The problem in your own words, with real examples
  • A budget range, even a wide one
  • Constraints you cannot change, and the reason for each
  • The people who will maintain the site and their skills
  • Open questions you would like the company to answer

Leave out

  • Page layouts and wireframes drawn before any research
  • Every feature anyone has ever wished for, with no priority
  • Technology choices made because a competitor uses them
  • Deadlines with no reason behind them
  • Internal disagreements left for the company to resolve

The budget question worries many buyers. Stating a range does not mean every proposal lands at the top of it. It lets each company size its answer to what you can spend, and tell you honestly when the goals and the budget do not match.

What to do next

Send the same brief to each company on your shortlist, and use the same questions with each. Our guide on how to choose a website development company covers the questions and a scorecard for the proposals that come back.

If you would like a second pair of eyes first, send us your brief. We will tell you what we would ask, change or cut, and how our website design service would approach it. When the project is still too open to brief, a product discovery workshop is the usual way to get there.

Common questions

How long should a website project brief be?

Two or three pages cover most projects. Longer briefs tend to bury the goals under detail, and companies skim them. If you have supporting material, such as analytics exports, brand guidelines or a content inventory, attach it instead of pasting it in.

Should I include my budget in the brief?

Yes, as a range. Without one, companies guess, and you receive proposals for different projects at different sizes. A range lets them design the best answer for what you can spend. It also brings out early whether your goals and your budget fit together.

What is the difference between a brief and a request for proposal?

A brief describes the project. A request for proposal adds the formal process around it, such as submission format, deadlines, legal terms and scoring rules. Small and mid-sized projects usually need only a brief and a short covering email. Public bodies and large organizations often require the formal version.

Who should write the brief?

The person who will own the website after launch, with input from sales, support and whoever manages the systems it connects to. One author keeps the voice and the priorities consistent. A decision maker should read and approve it before it is sent.

Can a development company write the brief for me?

A company can help you shape it, and many will. The risk is a brief written around what that company prefers to build. If you need help defining the project, pay for a discovery phase that ends with a document you can take to any company.
