The Website Planning Checklist: How to Map, Plan and Brief Your Startup Website

Most startup websites are built before they're planned. The result: a site that looks fine, says nothing useful and converts nobody. Planning comes before briefing. Always.

Here is how most startup websites get built.

A founder decides it is time to launch. They hire a designer or developer, sometimes both. They share a few websites they like the look of. They say something like "I want it to feel modern and clean" and "we need a homepage, an about page and a contact form." The designer builds something. It looks good. The founder launches it.

Six months later, the site is being rebuilt. Because it was built for aesthetics, not for conversion. Because the copy was written around the design rather than the other way around. Because nobody planned what the site needed to do before deciding what it needed to look like.

Website planning is the work that happens before a designer is briefed and before a developer writes a line of code. It is not complicated — but it has a sequence. And skipping it is the reason so many startup websites require expensive rebuilds so soon after launch.

Step 1 — Define the Primary Goal

Before you map a single page, answer this question: what is the single most important thing this website needs to make a visitor do?

Not "learn about us." A specific action.

• Book a discovery call

• Buy the product

• Join the waitlist

• Download the guide

• Submit an enquiry

Every decision that follows; which pages to build, what copy to write, where to place buttons, is in service of that one goal. A website that tries to achieve five goals achieves none of them well.

Step 2 — Map the Pages

With the primary goal defined, map the pages the site needs, and more importantly, the purpose of each one.

The core pages most startup websites need:

• Homepage — introduces the brand, states the value proposition, directs visitors to the primary action

• About — builds trust, tells the story, explains the people and purpose behind the business

• Product / Services — describes the offer in enough detail for a visitor to decide whether it is right for them

• Pricing — if applicable, clear and specific (hiding pricing creates friction)

• Contact / Enquiry — the conversion point for visitors who are ready to take action

• Blog / Resources — content that builds authority and supports SEO (important but not urgent for launch)

Resist the temptation to add pages that feel important but have no clear purpose. Every page is a decision point for a visitor. Unnecessary pages create unnecessary decisions.

Step 3 — Write the Content Hierarchy for Each Page

The content hierarchy is what each page needs to communicate — and in what order.

This is not the copy. It is the plan for the copy. The skeleton before the words.

For each page, define:

• The primary message: the single most important thing this page communicates

• The supporting points: three to five points that support or expand the primary message

• The proof: what evidence, testimonials or specifics back up the claims

• The call to action: what the visitor is asked to do at the end of the page

Write this for every page before a single word of copy is drafted. It gives the copywriter — whether that is you or someone else, a clear brief that results in copy that does its job.

Step 4 — Define the CTA on Every Page

Every page has one job. The CTA is the action that completes that job.

A common mistake is having multiple CTAs on a page; "buy now," "learn more," "get in touch," "download the guide", which creates decision paralysis and reduces conversions.

Define one primary CTA per page. It can be supported by a secondary CTA, but the hierarchy should be clear: one action is the obvious primary choice.

Map this for every page in your plan before you brief anyone.

Step 5 — Plan the Copy Before the Design

Copy leads. Design follows.

This is counterintuitive for most people because the design is what they can see — but it is the principle that separates websites that convert from websites that look good.

When design is built before copy, the copy gets squeezed into spaces that were not designed to hold it. Headlines get shortened to fit. Key messages get cut because there is no room. The result is a beautiful site with ineffective messaging.

When copy leads, the designer understands exactly what needs to be communicated on each page — and the design serves the message rather than competing with it.

Write the copy hierarchy (Step 3) and the CTAs (Step 4) before the design begins.

Step 6 — Brief the Designer

With your page map, content hierarchy and CTA architecture in place, you are ready to brief a designer.

A complete design brief includes:

• Brand guidelines — logo, colours, typography, tone of voice

• Page map — every page and its purpose

• Content hierarchy per page — what needs to be communicated

• CTA locations — where the conversion points sit on each page

• Visual references — for direction only, not instruction

• Deliverables — exactly what files and formats you need

• Timeline and revision process

A designer working from this brief is building a conversion tool. A designer working without it is making creative decisions that belong to the strategist.

Step 7 — Brief the Developer

Once the design is approved, the developer brief follows.

A complete developer brief includes:

• The approved designs — all pages, all states, all responsive breakpoints

• Platform decision — Shopify, Webflow, WordPress, custom build

• Functional requirements — forms, integrations, animations, e-commerce

• Performance requirements — load time targets, accessibility standards

• Timeline — phased delivery milestones, not just a final deadline

• IP ownership — everything built belongs to you from day one (get this in writing)

• Handover requirements — what you need to be able to manage the site after launch

Frequently Asked Questions

How long should website planning take? 

For a standard startup website of five to eight pages, a thorough planning process takes two to four days. That includes defining the goal, mapping pages, writing content hierarchies and preparing the brief. It feels slow relative to jumping straight into design — but it prevents the rebuild that otherwise happens six months later.

Do I need to write the copy myself? 

You need to write or direct the copy hierarchy — the structure and key messages for each page. Turning that into polished copy can be done by a professional copywriter if your budget allows. The hierarchy gives the copywriter everything they need to create copy that works — rather than copy that fills space.

What platform should I build my startup website on? 

It depends on the type of business. Shopify is the clear choice for product-based businesses with e-commerce requirements. Webflow is excellent for service businesses and startups that need design flexibility without custom development. WordPress remains a strong option for content-heavy sites. Custom development is only worth the investment when none of the above platforms can meet your requirements.

How many pages does a startup website need at launch? 

As few as possible while achieving the primary goal. A well-built five-page site that converts effectively is better than a twenty-page site that dilutes the message. Launch with the essential pages — homepage, about, product/service, pricing and contact — and add depth as you understand what visitors are looking for.

What is the most common website planning mistake? 

Starting with design before copy. When the visual design precedes the content planning, copy gets written to fit the design rather than the design serving the copy.

The result is a beautiful site where the messaging is compromised. Always establish what you need to say before deciding how it will look.

Stop Guessing. Start Building.

Plan your website before you brief anyone. It is the work that makes the build worth doing — and prevents the rebuild that skipping it creates.
