OUR WEBSITE DESIGN & DEVELOPMENT PROCESS

CLEAR STAGES, EXPERT DELIVERY AND NO SURPRISES

1

Client Introduction

You’ll meet our Project Coordinator and one of our Designer’s, who’ll be with you for the full journey. Together, we’ll outline your goals, agree on key milestones and walk you through the design process. We don’t set hard limits on design rounds because we believe in a collaborative approach, moving forward only once you’re confident, happy and ready.

2

Internal Kickoff

Our design and dev teams review your brief, technical requirements and sitemap. We book in the project and assign it within the wider development team to move efficiently from plan to production.

3

Design

Our in-house website designers collaborate closely with you from the start, creating your homepage concept together as the foundation for the rest of the site. Once you’re happy with the direction, we’ll move on to designing the remaining pages and mobile layouts, keeping you involved at each stage. You’ll see the creative take shape and have full sign-off before we move into development.

4

Development

Our developers build the site using our lightweight SDK or a tailored tech stack, depending on your needs. We review specs, keep your PM up to date, and if SEO is involved, the wider team is brought in. You can supply content and imagery during this phase for us to upload.

5

Content Population & Staging

We populate the site with your content, style everything consistently and provide access to a staging version for you to explore and review. Your feedback is actioned before final sign-off.

6

Pre-Launch Checks

Our technical SEO and dev teams run detailed pre-launch checks, covering speed, accessibility, redirects, security and more. Once complete, we book a launch date and keep you fully informed.

7

Go Live

Your new, professional website goes live. We handle the technical checks, make sure everything works as expected, and remain on-hand to support you as your new website starts delivering results.

8

Training & Aftercare

Unlike other agencies that send you a simple word document, we set up training sessions as there’s no point in having a website you can’t use. We will offer you a comprehensive overview of how to update content across the website and how to handle your website to ensure a strong online presence.

A TRUSTED PORTSMOUTH WEBSITE DESIGN AGENCY SINCE 2006

BUILDING WEBSITES THAT DO MORE THAN JUST LOOK GOOD

For almost two decades, we’ve been helping Portsmouth businesses build websites that perform. From Clipper Marine and Blue Star Asbestos to independent retailers, professional services and the city’s growing tech scene, we understand what it takes to create a site that reflects your brand and drives measurable results.

YOUR WEBSITE SHOULD DRIVE LOCAL AND NATIONAL GROWTH

Too many Portsmouth businesses are held back by websites that are slow, hard to update or no longer fit for purpose. We build sites that go further by combining clean design, SEO-focused architecture and CRO insight so your website actively supports growth. Whether you’re an eCommerce retailer looking to expand beyond Hampshire, a professional services firm competing across the South Coast, or a local venue attracting footfall, we start with discovery to understand your audience and deliver results.

BUILT FOR THE WAY PORTSMOUTH BUSINESSES OPERATE

We design future proof websites that support the way your team actually works. That means content management your team can actually use, integrations with the systems you rely on, and scalability that supports long-term growth. From WordPress builds using our custom SDK to headless solutions powered by React and Next.js, we select the technology that best fits your business, not the other way around.

PERFORMANCE, ACCESSIBILITY & SEO FROM DAY ONE

Our development approach is performance-first. From schema markup and Core Web Vitals optimisation to WCAG accessibility compliance, we make sure your site is fast, secure and easy for search engines to crawl. The result is a website that not only looks impressive but also ranks well, converts smoothly and adapts as your business evolves.

RELIABLE, LOCAL & HERE FOR THE LONG TERM

With nearly 20 years of experience in Portsmouth, we’ve delivered websites and digital projects for recognised names including Covers Timber & Builders Merchants, Horizon Leisure, Online Safety UK and Time4Nutrition. Every project is managed entirely in-house, with our designers, developers, SEO experts and digital marketing specialists working side by side to deliver consistent, measurable results.

A STRATEGIC PARTNERSHIP BEYOND LAUNCH

A website is never “finished.” That’s why we remain involved after launch, offering technical support, SEO audits, CRO testing and design improvements to ensure your site continues to deliver. With boxChilli, you don’t just get a new website, you gain a long-term partner who understands Portsmouth and is invested in your growth.

FREQUENTLY ASKED QUESTIONS

Cant find the answer you are looking for?
Get in touch and we will be happy to help

Q. What’s the difference between a custom WordPress site and a headless website?

A.

A custom WordPress site uses the traditional CMS with everything closely connected – ideal for Portsmouth businesses that need control and easy editing for their marketing team. A headless website separates the backend from the frontend, giving you lightning-fast performance, modern technologies like React or Next.js, and flexible integrations with third-party tools.

Q. Will my new website be optimised for SEO?

A.

Yes, our web developers build every site with SEO in mind from day one. That means fast loading times, mobile-first design, clean semantic code, schema markup and optimised metadata. If you’re moving from another platform, we’ll manage redirects and preserve rankings so your Portsmouth business doesn’t lose visibility.

Q. Do I need to rebuild from scratch or can you improve my existing website?

A.

It depends on your goals and how your current site was built. If your site has a strong foundation, we can often make performance, design and usability improvements without starting from scratch. But if it’s holding back your growth, whether due to bloated code, poor structure or limited flexibility, investing in a brand new website may be more cost-effective in the long run.

Q. Will my website be mobile-friendly?

A.

Absolutely. Mobile usability is standard in our process, and every website is tested across devices and browsers. This matters in a city like Portsmouth, where mobile-first browsing is common across sectors from retail to hospitality.

Q. What is a CMS and which one should I use?

A.

A CMS (Content Management System) is what allows you to manage your website content without needing a developer. We typically recommend WordPress for its flexibility, SEO-friendliness and ease of use, but we also build with modern frameworks for clients who need more advanced content workflows or eCommerce capabilities like an online store.

Q. How long does it take to build a website?

A.

Most projects take 16 to 28 weeks, depending on scope and functionality. Smaller brochure sites move quickly, while larger platforms with custom features or eCommerce can take longer. We’ll always give you a clear timeline with milestones so you know what to expect.

Q. Will there be any training provided on how to use and manage the site?

A.

Yes. Once your site is live, our website support team provide tailored training either 1:1 or via recorded video walkthroughs, to help your team feel confident updating content, managing media and making structural changes through the CMS.

Q. What platforms or CMS do you work with?

A.

We primarily build with WordPress and our own developer-approved SDK, but also work with Shopify, Magento and modern headless stacks like React and Next.js. As a Portsmouth web development company, we’ll recommend the best-fit solution based on your goals, internal capabilities and future plans.

Q. How much do your websites cost?

A.

Costs vary depending on size and complexity. A simple brochure site will naturally be more affordable than a large-scale eCommerce build with custom integrations. We’re upfront about pricing and can also suggest phased approaches for growing Portsmouth businesses that want to scale in stages.

Q. How quickly will I see results?

A.

Yes, we handle SEO-friendly migrations all the time. That includes mapping old URLs, implementing 301 redirects, preserving metadata and internal links, and tracking pre- and post-launch performance to minimise disruption and retain visibility.

Q. What’s your approach to web design and development?

A.

We take a strategic, user-first approach. Our process starts with discovery and planning, where we explore your goals, customers and target audience. From there we develop wireframes and design concepts that align with your branding services and business needs. We then build clean, high-performing websites that support long-term growth.

Q. How do you keep websites performing after launch?

A.

We don’t walk away once a site goes live. Our aftercare includes technical maintenance, SEO checks, CRO improvements and ongoing support. Many Portsmouth clients continue working with us long-term because they see consistent improvements rather than one-off fixes.

Q. What makes boxChilli different from other web agencies?

A.

We’ve been building websites since 2006 and have grown up alongside Portsmouth’s business community. All work is done by our in-house team of designers, developers and SEO specialists – no outsourcing, no shortcuts. That mix of local insight and technical expertise means we can create websites that are both high-performing and relevant to your audience.

Q. We have a limited budget, will you still work with us?

A.

We’re happy to scope projects of different sizes and suggest phased approaches where possible. If a full custom build isn’t viable right now, we can offer scaled-down solutions or roadmap support to help you move forward strategically.

Q. What are your values and how do they shape the work you do?

A.

At boxChilli, our core values (integrity, creativity and client focus) are built into everything we do. We’re honest about what will work, proactive in solving problems and always shape our recommendations around your business goals and data. Our work goes beyond the website – it’s part of your broader digital strategy and supports the digital services that keep your business moving.
