How to Brief a Web Agency: The Document That Gets You a Better Website

Most website projects go wrong before the first design mockup is ever seen.

The problem isn't the agency. It isn't your budget. It's usually the brief — or the absence of one.

A good brief gives the agency what they need to make the right decisions at every stage of the project. A poor brief forces them to guess, and every guess is a risk of building something you didn't want.

Why Your Brief Determines Your Website

Agencies build what they're told to build. When the instruction is 'we need a new website, make it modern and clean', you'll get whatever that agency's default interpretation of modern and clean happens to be — which may have nothing to do with your customers, your industry, or your goals.

A precise brief changes the dynamic entirely. Instead of guessing, the agency is solving a defined problem. The result is faster, cheaper, and far more likely to perform commercially.

1. Business Context

Start with what your business actually does. Not the elevator pitch — the real version.

• What do you sell, and to whom? (Be specific about industry, company size, geography)
• What makes you different from your three nearest competitors? (Avoid 'quality and service' — every competitor claims that)
• What do you want visitors to do when they land on your site? (Name one primary action)
• Are there any topics, claims, or visuals you explicitly don't want on the site?

2. Goals and Success Metrics

A website that 'looks more professional' is not a goal. A goal is measurable.

• "We want to increase inbound enquiries from B2B buyers by 40% within 6 months"
• "We need to rank on page 1 for three specific search terms"
• "We want to reduce pre-sales support calls by giving visitors better self-service information"

If you can't describe what success looks like in numbers, you won't be able to evaluate the finished site — and neither will the agency.

3. Target Audience

Don't describe your audience in demographics. Describe them in psychology.

Not: '35–55 year olds, B2B, mid-market.' Instead: 'A managing director at a 15–50 person professional services firm, frustrated by their current site's inability to reflect the company's actual quality. They've probably had a bad agency experience before and are cautious.'

The more accurately you describe how your ideal client thinks and feels, the more precisely the agency can write copy and design pages that speak to that person.

4. Technical Requirements

Be explicit about anything that affects the build:

• Do you need a CMS that non-technical staff can update — and which one?
• Are there third-party integrations required? (CRM, booking system, payment processing, ERP)
• Do you need the site in multiple languages? (How many, and who manages translations?)
• Are there compliance requirements? (GDPR, accessibility standards, industry-specific regulations)
• What is your current hosting situation and do you want to keep it?

Leaving these until mid-project causes scope changes and extra costs. An agency that knows the technical requirements upfront can price and plan accurately.

5. Design Direction

You don't need to know design. You need to share direction.

• Find 3–5 websites you like — anywhere in the world, not necessarily your industry — and note specifically what you like about each one (layout, colour palette, photography style, tone of copy)
• Share your existing brand guidelines: logo files, colours, fonts
• Share examples of what you explicitly don't want — 'not corporate blue', 'no stock photography of people shaking hands'

The goal is to reduce the number of revision cycles that happen because the agency guessed wrong about your taste. Good design direction compresses the project timeline significantly.

6. Content Ownership

This is where most projects stall. Who writes the copy for each page? Who provides the photography? Are these existing assets or does new content need to be created from scratch?

Be honest in the brief:

• "We have a copywriter who will handle all page copy"
• "We will write the copy ourselves — allow 3 weeks per round"
• "We need the agency to handle all copywriting"
• "We have professional photos from a recent shoot" vs "we will need photography arranged"

Content creation is often the longest phase of a website project — and the phase most consistently underestimated by business owners. Build it into your timeline honestly.

7. Timeline and Budget

Many business owners are reluctant to name a budget because they're afraid it anchors the price too high. The opposite is true.

A budget range tells the agency what level of solution to propose. Without one, agencies either over-engineer (proposing €50,000 of work when you need €12,000 of work) or underscope (building something that won't meet your goals).

State your ideal launch date and any hard deadlines — a conference, a product launch, a seasonal peak. State your budget range honestly. A good agency will tell you what's achievable within it. If you can't afford what you actually need, you'll find out before you've signed anything.

What a Good Agency Does With a Good Brief

A professional agency will read your brief, return with clarifying questions, and propose a specific solution with a clear scope, timeline, and price. They'll push back on requirements that add cost without adding value. They'll flag risks you haven't considered.

That's the dynamic you want. A brief that says nothing produces an agency that promises everything and delivers whatever's easiest.

Brief Checklist

Before you contact any agency, confirm your brief covers:

• What your business does and who it serves (specific)
• Your three nearest competitors and how you differ
• Primary conversion goal — the one thing visitors should do
• Ideal customer profile described in psychology, not demographics
• Technical requirements and any required integrations
• 3–5 design reference sites with notes on what you like
• Content ownership plan for copy and photography
• Budget range and target launch date
