A good design brief is the difference between a web project that delivers and one that derails. It's the document that explains what you want, why you want it, and what success looks like. Too vague, and designers will guess. Too detailed, and you're micromanaging every decision. Getting the balance right is key to project success.

This comprehensive guide walks through what a solid website design brief includes and how to think through each section. If you're commissioning a new website, a redesign, or even a substantial refresh, a good brief will save time, reduce revisions, and help you get what you actually need. We've seen projects fail because of poor briefs and succeed spectacularly because the brief was clear.

1. Business Goals and Objectives

Start here. What does the website need to do for your business? This isn't about features—it's about outcomes. What's the website supposed to achieve?

Be specific:

• Generate leads and enquiries for a service business? How many per month would success look like?
• Sell products directly? What's your target revenue?
• Build brand awareness and credibility? Who do you want to reach?
• Provide customer support or reduce support costs? Which support functions should the site handle?
• Rank for specific keywords in search results? Which ones matter most?
• Support a physical location or multiple locations?

Example of vague: "Increase online presence." Example of specific: "Generate 10 qualified leads per month from visitors in Cork and surrounding counties who are searching for electrical contractors." The specific version tells the designer everything they need to know about what matters.

The designer needs to understand what success looks like so they can make decisions that serve your goals. Do you want a clear path to a contact form? Product showcases with strong conversion CTAs? SEO-optimised blog sections? These decisions depend on what the site is supposed to achieve. Even design style choices should support your business goals.

2. Target Audience

Describe who you're trying to reach. Not everyone. Your actual target customer. This shapes every decision a designer makes—from copy tone to visual style to information architecture.

• Job titles or roles (decision-makers, end-users, influencers)
• Industry or business type
• Company size (if B2B)
• Geographic location (local, national, international?)
• Buying stage (do they know they need you, or are you trying to create awareness?)
• What pain points are they experiencing?
• What do they value most (price, quality, convenience, expertise)?

Example: "We target marketing managers at tech companies with 20-200 employees across Ireland. They're evaluating whether to build in-house versus partner with an agency. They value expertise and a clear ROI case. They're technical but may not be familiar with our specific approach."

This shapes the entire site. Copy tone, design style, what features matter, how you present credentials—all of it depends on knowing who you're talking to. A website targeting sophisticated tech buyers looks completely different from one targeting small business owners.

3. Competitor Analysis

Look at three to five of your direct competitors' websites. What are they doing well? What are they missing? Where do you want to differentiate? You don't need to copy competitors—the goal is to understand the landscape and identify opportunities.

• What's their value proposition and how is it communicated?
• What features or sections do they include (case studies, pricing, team bios, testimonials)?
• What's the overall tone and style?
• How is information structured and navigated?
• What would you do differently?
• Where are they strong that you could match?
• Where are they weak that you could capitalize on?

If every competitor hides pricing, that's an opportunity to be transparent. If every competitor looks stiff and corporate, that's an opportunity to feel more approachable. If every competitor lacks case studies, adding them becomes a differentiator.

4. Brand and Design Preferences

Describe how you want to be perceived and what design style feels right. This is where subjective preferences come in, but articulate them in terms of impression rather than specific elements.

• Brand personality (professional, approachable, playful, premium, practical?)
• Colour preferences or existing brand colours
• Design style (minimalist, bold, decorative, traditional, modern?)
• Examples of websites you like (not necessarily competitors—could be from completely different industries if the design style appeals to you)
• Any design elements you definitely want or definitely don't want
• Logo files and any existing brand guidelines
• Aesthetic inspiration (photography style, typography preferences, etc.)

Example: "We're a financial advisory firm. We want to feel trustworthy and expert, but not stuffy. We like the approachable professionalism of [Website A]. We want blues and greens (linked to growth and trust), and we like clean, open design rather than heavy graphics. We prefer sans-serif typography that feels modern."

5. Content Inventory and Structure

What content do you need on the site? Designers need to understand the scope of content to properly structure pages and allocate space.

• Main sections and pages (Services, About Us, Blog, Case Studies, Contact, etc.)
• How many services, products, or team members to include?
• Approximate word count (rough, but helps designers understand content volume)
• Do you have existing content, or are you starting from scratch?
• What content exists as drafts versus what needs writing?
• How often will content be updated?

Include a simple sitemap showing page hierarchy. Something like:

• Home
• Services
• — Service 1
• — Service 2
• — Service 3
• About Us
• Team (with 5 team members)
• Case Studies (with 6 case studies)
• Blog (with weekly posts)
• Pricing
• Contact
• Privacy Policy
• Terms of Service

This tells designers how complex the site is and how much space different sections need. A simple 5-page site looks completely different from a 50-page site with product listings and blog archives.

6. Technical Requirements

What technical needs does your site have? Understanding these upfront prevents "we didn't know you needed that" conversations halfway through the project.

• E-commerce (do you need to sell products?)
• Blog functionality and frequency (updates 2x/week? daily?)
• Email capture or lead forms? (contact forms, newsletter signup, webinar registration?)
• Integration with booking or appointment systems?
• Integration with CRM or email marketing platforms?
• Multilingual requirements?
• Existing integrations or systems that need to work with the site?
• Hosting preferences or existing hosting provider?
• SEO and search rankings are important?

The designer and developer need to understand technical constraints and integrations so they can plan accordingly. Some features add significant complexity and cost; knowing about them upfront prevents surprises.

7. Timeline and Milestones

When do you need this done? Be realistic about timing.

• Target launch date
• When do you need design concepts for feedback?
• When do you need copy finalized?
• Are there hard deadlines driven by marketing campaigns or business milestones?
• How much time can you realistically dedicate to reviews and feedback?

Be realistic. A good website takes time. Typical timelines:

• Small site with existing content: 6-10 weeks
• Small site that needs copy: 8-12 weeks
• Mid-size site with custom features: 12-16 weeks
• Large site or complex integrations: 16+ weeks

If you say you need it in 4 weeks, you're either cutting scope or you'll be unhappy with quality. Rushing a website project always reduces quality and increases revisions. Be honest about your timeline and prioritize features if needed.

8. Budget

What are you prepared to invest? Budget directly constrains scope. You can't have a complex, custom-built site for budget pricing. You need to align expectations.

You don't need to reveal the exact budget upfront (some designers will build toward it rather than to your goals), but a range helps. "€3,000-5,000" versus "€10,000+" completely changes what's possible. A €3,000 budget means template-based design with minimal customization. A €15,000 budget means custom design with more advanced features.

Also include ongoing costs:

• Hosting: typically €100-300/year for small business sites
• Maintenance and updates: €50-200/month if wanting professional support
• SSL certificate: usually included with hosting
• Email: if you need business email, factor in €5-10/person/month

Designers can't work magic. Budget constrains scope. Knowing what you're prepared to invest helps them recommend the right approach and feature set.

9. Constraints or Special Considerations

Anything else that matters for the project? Good design thinking requires understanding how to approach the design problem systematically. Resources like the Design Council provide frameworks for structured design processes that can guide your project approach.

• Existing systems you need to maintain or migrate from
• Compliance requirements (accessibility standards, GDPR data protection, industry regulations)
• Performance requirements (fast load times, mobile-first, etc.)
• Platforms you're restricted to (must be WordPress, Shopify, custom built, etc.)
• Content that must be migrated from an existing site
• Geographic or legal considerations

10. Success Metrics

How will you measure whether the website worked? Define this upfront so you can track it afterward.

• Number of leads or enquiries generated?
• Conversion rate targets?
• Search engine ranking targets?
• Traffic targets?
• User engagement metrics (time on site, bounce rate)?
• Customer satisfaction (feedback, testimonials)?

Define these upfront so you can track whether the site is achieving what you needed. "Generate 10 leads per month" is measurable. "Improve online presence" is not. Specific metrics let you evaluate success objectively.

Putting It Together

Your brief doesn't need to be a formal 50-page document. A good brief is typically 2-4 pages covering the above sections clearly. What matters is clarity and completeness, not length.

A good brief answers these questions:

• What does this site need to do for the business?
• Who are we trying to reach?
• What do we want them to do?
• How should we look and feel?
• What needs to be included?
• When do we need it, and what's the budget?
• How will we know if it worked?

You don't need to have all answers perfectly figured out. Designers are good at asking clarifying questions. But the more you've thought through these points, the faster the project will move and the better the outcome. A thorough brief is your insurance policy against scope creep, miscommunication, and disappointed deliverables.
