Website Design & Development

A website that looks the part and does the work.

Your website is where most of your marketing ends up. Every ad, email and search result sends people there, so it has to be clear, fast and persuasive. We design and build websites that express your brand with care and guide visitors towards action, on platforms your team can actually manage, then keep improving them based on how real people use them.

Every part of your website, working as one system

Strategy & Structure

We start with who visits, what they need and what you want them to do. That shapes the site map, page structure and content plan, so the design solves real problems instead of decorating them.

An AI agent that watches how your website performs

Your website comes with an agent that monitors speed, behaviour and conversions around the clock. Ask where people drop off, which pages convert or what is slowing the site down, and get a clear answer backed by live data.

It spots problems, suggests tests and drafts copy and fixes. Our designers and developers review every change before it goes live, so your site improves steadily without ever being put at risk. Nothing ships without a human check.

You
Where are visitors dropping off?
Most leave the pricing page without scrolling to the plan comparison. On mobile it sits below a long introduction, so I have drafted a shorter layout for the team to review.
You
Is the site running quickly?
Mostly, but large hero images are slowing the product pages on mobile. I have listed the affected pages and the fixes needed, ready for the developers to approve.

Why your website works harder with Vertical

A website should be designed around the marketing that drives people to it. Because one team runs brand, creative and performance, your site is built to convert the traffic we know is coming.

Designed to convert

Every page has a clear purpose and a clear next step, shaped by what we see in your campaigns and analytics.

Fast by default

Lean builds, optimised images and careful development keep pages quick on every device.

Easy to manage

We build on platforms such as Webflow and Shopify so your team can update content without calling a developer.

Ready for search

SEO and AI search foundations are part of the build, so the site can be found from day one.

AI with human judgement

AI speeds up content, testing and quality checks. Our designers and developers decide what ships.

Improved after launch

We keep testing and refining once the site is live, so it gets better rather than slowly going stale.

Website design and development questions, answered

What does a website design and development agency do?

A website design and development agency plans, designs and builds websites, and often supports them after launch. At Vertical that covers strategy and site structure, user experience and interface design, copywriting, development, SEO foundations, analytics and conversion tracking, launch and ongoing optimisation. Because we also run brand, creative and performance marketing, we design sites around how your customers actually arrive and what they need to see to take the next step. The result is a website that reflects your brand, is easy for your team to manage and gives every visitor a clear reason to take the next step.

Which platforms do you build websites on?

We build most often on Webflow for marketing and content-led websites and Shopify for ecommerce, and use modern frameworks where a project needs more custom functionality. The right choice depends on your goals, your team and how you plan to manage the site. Webflow and Shopify both let non-technical teams update content easily, which matters more than many brands expect. We will recommend the platform that suits your needs rather than the one we prefer. We also consider integrations with your existing tools, such as your CRM, email platform and analytics, before making a recommendation.

How long does it take to design and build a website?

Timelines depend on the size and complexity of the site. A focused marketing website might take a matter of weeks, while a larger site with many templates, integrations or ecommerce functionality can take a few months. The main stages are discovery and strategy, design, content, development, testing and launch. We agree a clear timeline and review points at the start, and we keep you involved throughout so decisions are made quickly and there are no surprises. Larger projects can also be launched in phases, so the most important pages go live sooner.

Will our new website be optimised for search engines?

Yes. SEO is built into our process from the start rather than added after launch. That includes clean site architecture, fast page speeds, mobile performance, structured data, sensible URLs, metadata and proper redirects when replacing an existing site. Redirects are especially important during a redesign, because they protect the rankings and traffic your current site has already earned. We also consider how content is structured for AI search tools, so the site is ready for how people search today. We check everything again after launch.

Can you redesign our existing website?

Yes. We start by reviewing how your current site performs, including analytics, search visibility, user behaviour and what your team finds difficult to manage. That tells us what to keep, what to improve and what to rebuild entirely. Sometimes a full redesign is the right answer and sometimes a series of targeted improvements delivers more value with less risk. We will give you an honest recommendation based on what the evidence shows. Where a redesign does go ahead, we protect your existing search rankings, content and integrations throughout the switch, so customers and search engines experience a smooth transition.

How do you design websites that convert?

We start with a clear understanding of who visits, what they are looking for and what stops them from acting. Then we design pages with a clear hierarchy, persuasive copy, strong calls to action, trust signals and as little friction as possible. Because our team runs paid media, email and SEO, we can design landing pages and journeys around the traffic those channels send. After launch, we use analytics and testing to keep improving conversion rates over time. Every design decision is tied back to a clear goal.

Will we be able to update the website ourselves?

Yes, and we design for that from the start. On platforms such as Webflow and Shopify we set up content management so your team can edit text, images, blog posts, products and other content without touching code. We build flexible page sections that can be reused to create new pages while staying on brand. We also provide training and simple guides, and we are available for support whenever you need help with something more complex. You keep full ownership of your site and content.

Do you make websites accessible?

Yes. We design and build with accessibility in mind, following recognised guidelines such as WCAG. That includes sufficient colour contrast, readable typography, logical heading structures, keyboard navigation, descriptive alt text and forms that work with assistive technology. Accessible websites are easier for everyone to use, reach more people and often perform better in search. We test throughout development and fix issues before launch. We also use automated tools alongside manual checks, because some problems are only visible to a person using the site. Accessibility is reviewed again whenever new pages or features are added, so standards do not slip after launch.

Do you provide support after the website launches?

Yes. Launch is the start, not the end. We offer ongoing support covering updates, fixes, new pages and features, as well as continuous optimisation based on analytics and testing. Our AI agent monitors site speed, errors and conversion behaviour, flagging issues and opportunities for our team to review. Many clients also connect their website with our SEO, paid media and email services, so improvements to the site feed directly into better marketing results. Support can be arranged as an ongoing retainer or on a project basis, depending on how often your site needs attention.

How much does a new website cost?

The cost depends on the number of pages and templates, the complexity of the design, any integrations or custom functionality, whether copywriting and photography are included and which platform the site is built on. Rather than offering fixed packages that may not fit, we scope each project based on your goals and requirements. After an initial conversation we provide a clear proposal explaining what is included, so you can make an informed decision. We also explain where budget can be phased, so you can launch sooner and add further features once the site is live and proving its value.

Bring us the ambition. We’ll build the system behind it.
