How to Set Up Intent Data on Your B2B Website

Knowing how to write a B2B website brief correctly is the difference between proposals you can compare and proposals ranging from $20,000 to $200,000 for fundamentally the same work. A vague brief does not just produce unclear proposals. It produces incomparable ones.

A well-written brief creates a level playing field. Every agency is scoping the same project, responding to the same requirements, and being evaluated against the same criteria. That is the standard this article is written to.

Key Takeaways

• A brief is not a vision document it is a structured set of requirements, constraints, and evaluation criteria that agencies use to scope a project accurately and comparably
• Six sections, no exceptions project context, audience and goals, content and structure, technical requirements, timeline and budget, and decision process must all be present
• The budget range question is not optional withholding the range does not protect you from being overcharged; it produces proposals you cannot compare
• Eight to fifteen pages is the right length enough to specify requirements clearly without burying the agency in documentation they will not read
• The brief signals how you will behave as a client a clear, well-structured brief attracts better proposals and signals the quality of your internal process
• Requirements must be documented before the brief is written the brief is a structured summary of existing requirements, not a substitute for them

What Is a B2B Website Brief, and What Is It Not?

A brief is the document an agency uses to scope your project accurately. It contains requirements, constraints, context, and evaluation criteria. It is not a mood board, a list of websites you like, or a narrative description of your problem.

The difference between a brief and an RFP matters. A brief is used when you are approaching one or two agencies you have already identified. An RFP is used when you are running a formal competitive process and need structured, comparable responses from multiple agencies.

Vague briefs produce unusable proposals. An agency that receives a brief saying "we need a new website that reflects our brand and generates leads" will scope a project based on assumptions. Three agencies will make three different assumptions, producing proposals that cannot be compared or evaluated against each other.

A well-written brief does not become obsolete when the agency is selected. It remains the reference point for scope decisions throughout the project. Requirements that are not in the brief are not requirements the agency is responsible for.

What Goes Into a B2B Website Brief?

A complete B2B website brief covers six sections. Every section must be present, and each one contains specific information that enables accurate, comparable scoping. Before writing the brief, you need documented website requirements, the brief is a structured summary of those requirements, not a replacement for them.

The six sections:

• Section 1: Project context why this project, why now, what is wrong with the current site specifically, what business event is driving the timeline, and what has been tried before
• Section 2: Audience and goals buyer types, roles, industries, deal sizes, the primary job the site must do for each audience, and measurable goals with a baseline and 12-month target
• Section 3: Content and structure pages needed, content types required, what exists and can be reused, what needs to be created from scratch, and by whom
• Section 4: Technical requirements CMS requirements, integration requirements (CRM, MAP, analytics, chat), performance targets, compliance obligations, hosting environment, and bespoke functionality
• Section 5: Timeline and budget the launch date you are working toward, any internal milestones or freeze periods, and the budget range you are working within; both must be present
• Section 6: Decision process how many agencies are you briefing, what the evaluation process looks like, what a proposal must contain, who makes the final decision, and by when

What Should the Brief Cover About Scope and Deliverables?

Scope clarity is the single biggest driver of proposal accuracy. The more specifically you describe the deliverables, the more accurately and comparably agencies can price the work.

Do not describe scope in the form of a solution. Describe what you need the site to do and what it must contain. "The site must include a case study section with filterable categories and a contact CTA on each case study page" is a scope statement. "Build us a nice case studies page" is not.

What to include in the scope section:

• Page count or estimated page volume
• Key functional requirements including forms, calculators, gated content, and configurators
• Integration requirements with existing systems
• Content support expectations, does the agency write copy, design photography, produce videos?
• Post-launch requirements including maintenance, analytics reporting, and A/B testing

What scope is not your responsibility to define: you should not specify the platform, tech stack, or development approach in the brief. These are agency decisions based on your requirements. Specifying them prematurely removes the agency's ability to recommend the right solution for your needs.

A scope of work template gives you a structured format for the deliverables section, particularly useful if you want to ensure your brief produces itemised, comparable proposals.

How Do You Write the Goals and Audience Section?

The goal section contains specific, measurable outcomes tied to a current baseline and a 12-month target. "Generate more qualified leads" is not a goal. "Increase demo request submissions from 12 to 20 per month within six months of launch" is.

Audience requirements should be written for each buyer type:

• The role, industry or market segment, and typical deal size
• The buying authority and stage of the buying journey when they most likely reach the site
• The top three questions they need the site to answer before they will engage

The most useful audience information rarely lives in a persona document. It lives with the people who talk to buyers every day. Interview two or three salespeople before writing the audience section of your brief.

For each audience segment, state the conversion event the site must drive: demo request, content download, direct enquiry, or qualification form. This tells the agency which audiences to prioritize in architecture and conversion design.

How Long Should a B2B Website Brief Be?

A well-written brief for a mid-market B2B website is typically eight to fifteen pages. Shorter signals requirements have not been properly thought through. Longer typically means the brief is substituting documentation volume for clarity.

The two-page brief problem is common. A two-page brief signals requirements have not been properly examined. It produces scoping assumptions, incomparable proposals, and a first discovery session that is mostly about filling in the gaps the brief left.

The forty-page brief problem is equally common. Briefs that run to 40 or 50 pages typically contain too much process documentation, too many unfiltered stakeholder inputs, and too much prescription about how to build rather than what to build. Agencies skim them and miss critical requirements.

Format guidance:

• Use clear section headings and bullet points for requirements lists
• Include a one-page executive summary at the front
• Do not submit a brief as a narrative document; requirements buried in paragraphs are requirements agencies will miss
• Supporting documents belong in an appendix, clearly labeled and referenced from the relevant section

How Do You Share the Brief With an Agency?

The mechanics of briefing an agency effectively, how you present, what you ask, and how you evaluate responses, determine the quality of what you get back.

Send the brief before the briefing call, not during it. Agencies need time to read and formulate questions. A briefing call where the agency is seeing the document for the first time is not a briefing session. It is a read-along.

What a briefing call should accomplish:

• Clarify ambiguities in the brief
• Answer specific agency questions
• Signal the quality of your internal process

Compile agency questions after the call and send a written Q&A to all agencies simultaneously. This keeps the process fair and ensures every agency is working from the same information.

What to ask agencies in the briefing conversation: how they would approach the discovery phase, what their typical team structure looks like for a project of this scale, what they would need from you to scope accurately, and what the most common gaps they see in briefs of this type.

When Does a Brief Become an RFP?

Use a brief when approaching one or two identified agencies with a project under $80,000. Use an RFP when evaluating three or more agencies formally, the project exceeds $80,000, or procurement requires a documented selection rationale.

Use a brief when: - You have identified one or two agencies to work with - The project is under $80,000 - A formal evaluation structure with scored criteria is not required

Use an RFP when: - You are evaluating three or more agencies formally - The project exceeds $80,000 - Procurement requires a structured process - Project complexity requires standardized response formats for comparison

The hybrid approach: write a detailed brief as the foundation, then add an RFP wrapper (evaluation criteria, required response format, submission deadline) when you need to formalize the process. This avoids writing two separate documents.

If you need to move to a formal RFP, an RFP template gives you the structure to build from your brief without starting again. For the full process of how to write an RFP from scratch, that guide covers the additional elements a brief does not contain.

Conclusion

A well-written B2B website brief is the fastest path to proposals you can compare, agencies who understand your project, and a build that starts with shared expectations rather than assumptions. The time you invest in the brief is returned in reduced scope change, fewer revision cycles, and a site that does what you actually needed.

Open a new document and write one sentence for each of the six sections: project context, audience and goals, content and structure, technical requirements, timeline and budget, and decision process. Fill in those six sentences first. They are the skeleton. Everything else is expansion.

How LowCode Agency Reads B2B Website Briefs

LowCode Agency receives a large number of B2B website briefs. The ones that produce good projects and the ones that produce difficult ones are distinguishable within the first two pages. The difference is almost always specificity: specific goals, specific audiences, specific constraints, and a stated budget range.

Our B2B website development projects start from a brief conversation, whether that is a formal document or an early scoping call. You can see the kind of projects that come out the other side in our past project work.

• Brief review as part of scoping we give honest feedback on what a brief covers well and where the gaps are before any proposal is written
• Six-section structure enforced if a brief is missing a section, we will identify it before scoping begins rather than filling the gap with assumptions
• Budget range discussion standard we will ask for your budget range if it is not in the brief; we do not scope to guesses
• Audience interview support available if your audience section needs input from your sales team, we can structure and run those interviews as part of discovery
• Scope definition documented every project produces a written scope of work that references the brief and defines exactly what is and is not included
• Discovery-first process no design or development work begins without a structured discovery phase that validates the brief requirements against technical and commercial reality
• Briefing call structured for value our briefing sessions are designed to clarify requirements, not to pitch; you will leave with more clarity than you arrived with

We have built 350+ products for clients including Coca-Cola, American Express, Sotheby's, Medtronic, Zapier, and Dataiku.

If you have a brief you want to pressure-test before sending it out, send us your brief and we will give you honest feedback on what it does and does not cover.
