Website Design & Development

Your website is the first handshake, the shop window and often the deal closer. If it loads slowly, looks dated or buries key tasks, prospects leave before you can say hello. At BIG, we design and build sites that welcome users in, guide them smoothly to the next step and report every click back to your KPIs. We mix insightdriven UX, sharp creative and robust code to create pixel-perfect sites that look great and work even harder. Whether you need a brochure site to showcase expertise or a scalable ecommerce platform that powers sales round the clock, BIG will deliver. 

Why we do Website Design & Development

A high-performing site does more than look good. It: 

  • earns trust by demonstrating expertise and offering clear and transparent information 
  • drives conversions with clear journeys and lightning-fast performance 
  • supports SEO and paid campaigns by delivering relevant landing pages that match intent 
  • grows with the business, adding new products, languages or integrations without costly rebuilds 
  • captures first-party data you can use to refine marketing and product decisions 

In a digital-first buying journey, your website is the only channel you fully control. Investing in its speed, structure and story pays back every day.
