FREQUENTLY ASKED QUESTIONS

Categories

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 WordPress CMS with everything (frontend and backend) tightly coupled. It’s great for marketing sites that need full control and easy editing. A headless website separates the backend (where content lives) from the frontend (what users see), allowing for lightning-fast performance, flexible technologies like React or Next.js, and seamless integrations with third-party tools and AI platforms.

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 includes clean, semantic HTML, fast loading times, mobile-first design, schema markup, and metadata optimisation. If you’re transitioning from another platform, we also manage redirects and maintain existing SEO value, so your web presence doesn’t take a hit.

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, all our websites are responsive and tested across different mobile phones, screen sizes and browsers. Mobile usability is a key ranking factor and essential for user engagement, so we design and develop mobile-first experiences as standard.

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.

Timelines vary depending on project scope, but most websites take between 16 to 28 weeks from initial planning to launch. We’ll give you a clear timeline with milestones so you can track progress and provide feedback at every key stage.

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 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.

Website pricing depends on functionality, integrations, design complexity and size. We’re transparent about costs and offer flexible payment options to help you plan ahead. Whether you’re a startup or an established business, we’ll shape a solution that delivers value without compromise.

Q. Do you only work with local businesses?

A.

Not at all. While we’re based on the South Coast and have a strong local presence in Portsmouth, Southampton, Winchester, Chichester, Fareham, Basingstoke, Guildford and across Hampshire, we partner with brands nationwide. From Bournemouth to Bristol, Manchester to Edinburgh, we deliver fast, UX-led and secure websites for clients across the UK.

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.

Once your site is live, we can support you through our ongoing packages that include technical maintenance, performance checks, UX/CRO improvements and SEO audits. We offer monthly retainers or ad hoc support depending on your needs, all with the same team who built the site staying involved.

Q. What makes boxChilli different from other web agencies?

A.

As a web design agency of almost two decades, we combine creative thinking with deep technical knowledge. Unlike many marketing companies that offer templated sites, we build every solution from scratch around your brand, goals and market. You’ll always work with our in-house team – no outsourcing, no cut corners, just reliable delivery and honest communication.

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.
