Frequently Asked Questions

The questions worth asking are the ones that make the investment clearer.

Get Your Questions Answered
Which platforms do you build on?

From WordPress to Shopify, Laravel, React, Magento, Wix, SquareSpace, and any custom platform, plus custom builds and integrations where a project needs them. We recommend the platform that fits your goals and the team who will manage the site.

Can you speed up my existing website?

Yes. We audit Core Web Vitals, hosting, images, scripts and theme code, then fix the biggest bottlenecks first.

Do you only work with businesses in Northern Ireland?

No. We work with businesses across the UK, but we tailor every plan to the market you actually sell into, including the competitors you face in Northern Ireland.

How much does website development cost?

Pricing depends on scope, competition and your current website. After a free review we send a fixed written proposal, so you know exactly what is included before you commit.

Do I need a long contract?

No. After the initial project we work on rolling agreements. We would rather keep clients because the work pays for itself.

What do you need from me to get started?

Access to your website, Google Search Console and Google Analytics (we can help set these up), plus a short call about your goals, customers and best-selling services.

Can you work with my existing website and developer?

Yes. We regularly work alongside in-house teams and external developers. If you do not have one, our own developers can implement changes for you.

How long does website development take to show results in Northern Ireland?

It depends on your starting point and the competition. Quick technical and on-page fixes can show movement within weeks, while competitive Northern Ireland searches usually take three to six months of consistent work. We share a realistic timeline after the audit.
