How to Plan a Professional Website: A Practical Checklist

18. April 2026

A professional website starts with clear decisions about who it serves, what visitors need, and what the organisation wants to achieve. Without those decisions, even an attractive design can leave people unsure where to go or what to do next.

This website planning checklist will help you turn an initial idea into a useful project brief. You do not need every answer before contacting a designer, but identifying priorities and unanswered questions will make that first conversation more productive.

1. Define the website’s main purpose

Choose one primary outcome for the website. Secondary goals can support it, but a clear priority helps guide the structure, content, and budget.

Your main purpose might be to:

Generate enquiries for a service.
Sell products or accept bookings.
Explain an organisation’s work and attract supporters.
Help existing customers find information.
Encourage applications, registrations, or memberships.

Make the goal specific enough to guide decisions. “Improve our online presence” gives a designer little direction. “Help local businesses understand our services and request a consultation” identifies an audience, a need, and a next step.

Write one sentence:

Our website will help [audience] to [complete a task], supporting our goal of [business or organisational outcome].

2. Understand your audience’s needs

Describe your main visitors by what they are trying to accomplish. Details such as their familiarity with your organisation, language needs, and likely browsing circumstances can be more useful than broad demographic labels.

Consider:

What brings them to the website?
What do they need to know before taking action?
What concerns could prevent them from contacting you?
Are they likely to visit on a phone, at work, or while travelling?
Do different audiences need different information?

Use customer enquiries, staff feedback, and conversations with prospective users where possible. Record assumptions that still need checking.

For example, a potential customer may need a clear service explanation and evidence of relevant experience. An existing customer may simply need support details. Both journeys should be easy to follow.

3. Map the essential pages

Create a simple sitemap: a list of pages grouped in a logical order. Give each page a purpose before deciding how it should look.

Page	What it should help visitors do
Home	Understand the organisation and find the right next step
Services or products	Assess whether the offering meets their needs
About	Understand who is behind the organisation and why they are credible
Projects or case studies	See relevant work and supported results
Contact or booking	Make an enquiry or arrange an appointment

Add pages for your particular audience, such as membership information, resources, events, or support. Plan appropriate privacy information and other policies around the website’s activities.

A blog is optional. Include one when you have a useful subject to cover and someone responsible for maintaining it.

For every proposed page, complete two statements: “Visitors need this page because…” and “After reading it, they should be able to…”

4. Plan the content and assign owners

Content deserves its own schedule. A design cannot be reviewed properly if essential service descriptions, photographs, or contact details are still missing.

Prepare an inventory showing:

What content already exists.
What needs rewriting or creating.
Who will supply and approve each item.
When each item will be ready.

Gather brand files, service information, team biographies, photographs, and relevant project examples. Confirm permission to use supplied images and customer material.

Give priority to the questions visitors need answered before acting: what you offer, who it is for, how the process works, and how to get started.

For an existing website, identify content worth keeping and important pages whose addresses may change. Include redirect planning in the project scope so old links can lead visitors to suitable replacements.

5. Separate essential features from future additions

List the functions visitors and staff need, then mark each as required for launch or suitable for a later phase.

A contact form, booking system, online payment facility, member area, or multilingual setup can each affect the project differently. Describe the intended behaviour rather than naming a feature alone.

For example, specify where booking requests should go, whether appointments need approval, and what confirmation the visitor should receive.

Also explain what staff need to manage. Someone who regularly updates service pages may need a straightforward content management system and training.

For each feature, record the user need it serves, any existing system it must connect to, and who will operate it after launch.

6. Include usability and accessibility from the start

Plan for visitors using different screen sizes, keyboards, assistive technologies, and levels of digital confidence.

Your brief should cover readable text, clear navigation, descriptive links, labelled forms, useful error messages, and access to essential tasks on mobile devices.

Accessibility also needs ownership, time, and review. The W3C’s guidance on planning and managing web accessibility recommends integrating it throughout the website process, including assigning responsibilities and evaluating work early and regularly.

Ask the designer to explain the accessibility target and how it will be assessed. Include time for representative visitors to try important tasks, such as finding a service or completing an enquiry.

7. Agree on success measures

Connect measurement to the website’s purpose. Visitor numbers alone will not tell you whether people are finding what they need.

Useful measures might include:

Qualified enquiries received through the website.
Completed bookings or registrations.
Purchases or membership applications.
Successful completion of common support tasks.

Define what counts. A qualified enquiry, for example, might mean a request for a service you actually provide within your operating area.

Record an existing baseline where available. For a new website, set an initial review period and use early results to establish realistic targets.

Assign someone to review performance and act on findings. Agree on suitable measurement tools and privacy requirements before implementation.

8. Set the budget, responsibilities, and launch conditions

Share a realistic budget range and explain any fixed deadline. Distinguish a preferred launch date from one tied to an event or contractual commitment.

Account for content production, photography, hosting, ongoing subscriptions, maintenance, and staff training as well as design and development.

Name one person who can coordinate feedback and approve decisions. Agree on review dates and what must be ready before launch, including tested forms, approved content, and access to essential accounts.

Clarify who will control the domain, hosting, and website administration, and what support will be available afterwards.

A website design brief you can prepare

Copy this checklist into a document and complete it before approaching designers. Mark uncertain items as “to discuss.”

Organisation: What we do and whom we serve.
Primary goal: The main outcome the website should support.
Audience: Key visitor groups, their tasks, and their concerns.
Main action: What we want visitors to do next.
Pages: Proposed sitemap and purpose of each page.
Content: Available materials, missing items, owners, and deadlines.
Features: Launch requirements, integrations, and later additions.
Design direction: Brand assets and examples, with reasons we find them useful.
Usability and accessibility: Requirements and agreed review approach.
Success measures: Outcomes, baseline, and review responsibility.
Delivery: Budget range, timing, decision-maker, and approval process.
Ongoing management: Editing, maintenance, account ownership, and support needs.

Send the same brief to each designer you approach. Ask proposals to identify deliverables, assumptions, exclusions, and ongoing costs so you can compare what each project will provide.
