How to Write a Website Brief in 2026

In brief: A website brief is a management tool that prevents misunderstandings, locks in the budget, speeds up production, and ensures the final website matches your business goals. Follow 7 steps: define objectives, identify target, list features, define site map, envision design, plan timeline/budget, and plan maintenance.

A website brief is not an "administrative" document. It is a management tool. It prevents misunderstandings, locks in the budget, speeds up production, and ensures the final website matches your business goals.

Here is a simple 7-step method to write a clear, actionable, results-oriented brief.

1. Why a Website Brief Is Essential

Creating a website without a brief is like starting construction without blueprints.

You can get there, but you will pay for it with:

• Delays
• Back-and-forth
• "Oh by the way, we also wanted..."
• Budget overruns

In 2026, this is even more true because a website is no longer just a showcase. It must handle SEO, mobile, conversion, sometimes automation, and sometimes e-commerce.

All of this needs to be defined from the start.

2. What Is a Website Brief?

A website brief is a document that describes in black and white:

The format does not matter. It can be a doc, a Notion page, a PDF, or a spreadsheet. What matters is that it is clear and complete.

It is also your insurance if the project goes off track: compare what was delivered to what was requested.

4. Who Should Write It?

The most effective approach is a duo:

If you do it alone, you risk missing technical points. If the provider does it alone, they risk producing something "nice-looking" but not aligned with business goals.

5. The 7 Steps to Write an Effective Website Brief

Step 1 — Define the Main Objective of the Site

This is the starting point. You choose one dominant objective, then secondary objectives.

Examples of main objectives:

• Generate quote requests
• Get appointment bookings
• Sell online
• Recruit
• Reassure / build brand credibility

Then, write what you specifically expect:

• "I want 30 contact requests per month"
• "I want 70% of visitors to find the booking option in under 10 seconds"
• "I want to sell X products with online payment"

This gives a clear direction.

Step 2 — Identify Your Target Audience

Your website must speak to someone. Not "the general public."

In your brief, include:

• Your primary target
• The 3 needs or fears that hold them back before buying
• The 3 reasons they choose a provider

Example format:

Target: B2B service SMBs Problems: lack of time, fear of making mistakes, need for ROI Triggers: proof, case studies, clear process

This block guides the UX, pages, tone, proof elements, and CTAs.

Step 3 — List the Features (Without Writing a Novel)

Here, you list everything the site should enable.

Very important: indicate what is mandatory, what is optional, and what is for later.

Step 4 — Define the Site Map and Content

This is the website structure: main pages, secondary pages, user journeys.

Create a simple site map:

Home
Services
   Service 1
   Service 2
Portfolio / Case Studies
Blog / FAQ
About
Contact / Booking

Then, specify the expected content page by page:

• Headings
• Sections
• Proof elements (reviews, photos, numbers)
• CTAs (contact, quote, purchase)

The clearer it is, the faster production goes.

Step 5 — Envision the Design and User Experience (UX)

Here, you are not playing designer. You are giving directions.

Include:

• The desired atmosphere (premium, minimal, accessible, institutional)
• Your colors / logo / visual identity if they exist
• 3 websites you like + why
• 3 websites you dislike + why

And especially: your non-negotiable UX rules

• Mobile-first
• Contact/purchase access in 1 click
• Speed and readability are priorities
• Short pages with clear sections

Step 6 — Plan the Timeline and Budget

Without dates and a budget envelope, the project derails.

In the brief, specify:

Practical note: if you do not have the content on time, the site will not launch. Budget does not compensate for missing materials.

Step 7 — Plan for Maintenance, Security, and Evolution

A website is never "finished."

In the brief, indicate:

This avoids unpleasant surprises after launch.

6. The 2026 Element Many Forget: SEO + AI Visibility

If you want to be found in 2026, you must include in the brief:

• SEO optimization from the design phase (structure, pages, speed)
• Blog / FAQ to answer questions
• Structured data (when relevant)
• Consistency with your Google Business Profile if local
• Clear content to be understood by AI systems

Otherwise, you will have a "clean" website that is barely visible.
