Performance-First Development
Every site achieves 95+ PageSpeed scores and sub-1.5s load times. We optimise images, implement lazy loading, and build on modern frameworks for speed that directly impacts conversions and rankings.
Custom web development builds websites and web applications with functionality beyond a standard template, bespoke features, third-party and API integrations, headless CMS, platform migrations, and performance engineering. Buttercup Digital Solutions develops custom, high-performance sites and web apps for Australian businesses using Next.js, React, and TypeScript, delivering sub-1.5s load times, 95+ PageSpeed scores, and scalable, SEO-ready architecture.
Custom websites and web apps, engineered to perform
For Australian businesses that need more than a standard website. Custom functionality, third-party integrations, platform migrations, and web applications, built on Next.js and React for speed and scale.
What goes into a custom, high-performance web build?
Custom web development goes beyond a template. It’s bespoke functionality, engineered performance, and architecture built to scale. A serious build combines:
Technical performance: 95+ PageSpeed scores, lazy loading, image optimisation, and CDN delivery.
SEO foundation: structured data (Schema.org), meta optimisation, semantic HTML, and clean URLs.
Conversion design: strategic CTAs, form optimisation, trust signals, and clear user journeys.
Scalability: modular architecture, headless CMS integration, and API-ready infrastructure.
Security & compliance: HTTPS encryption, privacy compliance, and secure forms and data handling.
Project Timeline
Discovery and planning in Week 1, development and testing across Weeks 2-3, with launch optimisation and 30-day post-launch support. Most standard sites go live in around 3 weeks; custom builds and web applications are scoped individually.
Why most business websites fail to convert
Outdated development practices and aesthetic-first design leave money on the table.
They Prioritise Aesthetics Over Performance
Beautiful designs mean nothing if your site takes 5+ seconds to load. 53% of mobile users abandon slow sites before they convert.
They’re Not Built Mobile-First
Over 65% of traffic is mobile, yet most sites are desktop designs shrunk down. Poor mobile UX kills conversions.
They Ignore SEO Fundamentals
Websites built without structured data, proper meta tags, or Core Web Vitals optimisation are invisible in search.
They Lack Conversion Strategy
No clear CTAs, confusing navigation, missing trust signals. These sites get traffic but never convert visitors into customers.
