Website Brief Template: Free Model and Writing Guide

Why the Website Brief Is the Key to Your Project

After supporting over 200 web projects in 10 years, I can tell you one thing with certainty: projects that fail almost never fail because of a bad developer or a poor design. They fail because nobody took the time to properly define the requirements upfront.

The website brief (or specification document) is the founding document of your web project. It is the roadmap that aligns your expectations with those of your service provider. Without it, you are navigating blind — and the results show: delays, cost overruns, and frustration on both sides.

According to a Project Management Institute study (PMI, 2025), 47% of digital projects that fail cite poorly defined requirements as the main cause. This figure rises to 62% for projects without a formalized brief. Let us take the time to do things right.

Essential Sections of a Website Brief

1. Company Presentation and Context

This section gives your provider the necessary context. Be thorough:

• Who are you? Business activity, size, founding date, location
• What is your market? B2B, B2C, local, national, international
• Do you have an existing site? If so, why do you want to redesign it? What are its weaknesses?
• Who are your competitors? List 3 to 5 competitors with their websites
• What is your brand identity? Existing logo, colors, typography

2. Project Objectives

Be as specific as possible. "Having a nice website" is not an objective. Here are actionable goals:

• Generate X quote requests per month via the contact form
• Increase organic traffic by X% in 6 months
• Enable online appointment booking
• Present the product/service catalog in a structured manner
• Recruit talent via a careers page

Each objective should be SMART: Specific, Measurable, Achievable, Realistic, and Time-bound.

3. Target Audience

Define your personas precisely. For each one, specify:

• Age range and geographic location
• Socio-professional level
• Problems and needs your business addresses
• Digital behavior (which devices, which social networks, which language)
• Typical journey on the site (what they come looking for)

Concrete example for an architecture firm in Casablanca:

4. Site Architecture and Content

The site map is your website's blueprint. List all planned pages with their hierarchy:

• Home
• About
• Our Story
• The Team
• Services
• Service 1
• Service 2
• Portfolio / Projects
• Blog
• Contact

For each page, specify: planned content, required visual elements, and specific features (form, map, gallery, etc.).

5. Technical Requirements

This is the section non-technical people tend to skip, but it is fundamental:

• Preferred technologies: WordPress, Next.js, Webflow? If you have no preference, say so and let your provider recommend.
• Responsive design: Mandatory in 2026. Specify any particular constraints (industrial tablets, very large screens, etc.)
• Performance: PageSpeed targets (we recommend > 90 on both mobile and desktop)
• SEO: Target keyword list, number of languages (French, Arabic, English?)
• Integrations: CRM, payment tools, Google Analytics, chatbot, newsletter, etc.
• Hosting: Do you have existing hosting or should one be recommended?

6. Design Preferences

Do not ask your provider to "guess" your taste. Prepare:

• 3 to 5 websites you like, with an explanation of what appeals to you in each (the colors? the navigation? the mood?)
• 3 to 5 websites you dislike, with reasons
• Tone and mood: corporate and serious? Modern and dynamic? Warm and artisanal?
• Colors: your brand colors, but also colors you absolutely dislike

7. Timeline and Budget

Budget transparency is critical. Too many clients refuse to share their budget, thinking the provider will take advantage. The opposite actually happens: without an indicative budget, the agency cannot properly scale its proposal.

Specify:

• Overall budget: Even a wide range (15,000 – 30,000 MAD) is infinitely more useful than "budget not defined"
• Desired launch date: With any constraints (event, commercial season)
• Intermediate milestones: Key dates for mockup approvals, content delivery, acceptance testing

8. Maintenance and Evolution

A point often forgotten in the initial brief:

• Who will manage content after launch? (Your internal team? The agency?)
• What level of training is needed?
• Do you want a maintenance contract?
• What future developments are planned? (E-commerce, client portal, blog, multilingual)

The 7 Most Common Mistakes

After years of receiving website briefs as an agency, here are the most frequent mistakes:

1. 1The 50-page brief: Too many details kill flexibility. 10 to 20 pages are more than enough.
2. 2Dictating the technical solution: Saying "I want WordPress" when your needs require a different technology closes the discussion.
3. 3Forgetting mobile: In 2026, a brief that does not mention mobile is incomplete by definition.
4. 4No visual examples: "I want a modern design" means nothing. Concrete examples are worth a thousand words.
5. 5Ignoring SEO from the start: SEO must be considered from the design phase, not bolted on later.
6. 6Budget "to be defined": This guarantees receiving inconsistent quotes and wasting time.
7. 7No deadline: Without a deadline, the project drags on indefinitely on both sides.

How to Use the Brief to Compare Agencies

Once your brief is written, send it to 3 or 4 agencies. With an identical brief, you can objectively compare:

• Understanding of the need (did the agency ask relevant questions?)
• Technical proposal (what solution do they recommend and why?)
• Proposed timeline (is it realistic?)
• Detailed budget (is the cost breakdown transparent?)
• Similar references (have they completed comparable projects?)

The best provider is not necessarily the cheapest or the most expensive. It is the one that best understands your needs and proposes a solution consistent with your budget and objectives.
