SIAGB is a website development company in Sydney that builds fast, secure sites designed for how the web actually works today. We use Hugo, headless CMS platforms, and AI-enhanced features to create websites that load instantly, rank higher, and don’t fall apart after six months.

The Challenge

Here’s what we see constantly. A business spends $15,000 on a WordPress site. It looks decent on launch day. Then the problems start.

Plugins need updating. Security patches pile up. The site gets slower every quarter as themes bloat and databases grow. Within 18 months, that shiny new website loads in 4+ seconds on mobile. That matters more than most people realise. Google’s own data shows that 53% of mobile visitors abandon a site if it takes longer than 3 seconds to load. That’s a critical metric for any business. Every extra second costs you roughly 7% in conversions.

So what do most agencies offer? More WordPress. Or worse, proprietary page builders that lock you into their platform. You can’t move your site without rebuilding from scratch. You’re paying monthly fees just to make basic text changes. And the design? It looks like every other template on the internet.

Why would you accept that?

Thing is, the web has changed. Google now ranks sites heavily on Core Web Vitals. AI crawlers from ChatGPT, Perplexity, and Google’s AI Overviews need clean, structured content to reference your business. Most websites built the old way simply weren’t designed for this. They’re stuck in 2019 while search has moved to 2026.

Our Approach

We don’t use WordPress. We build with Hugo, the fastest static site generator available, and pair it with headless CMS platforms that give your team full editorial control.

What does that actually mean for you? Your site loads in under a second. Wait, that’s not quite right. Under 800 milliseconds, typically. It scores 95+ on Google Lighthouse. There’s no database to hack, no plugins to update, and no server that can crash during a traffic spike. Hugo generates pure HTML files that get served from a global CDN. Simple. Fast. Bulletproof.

But speed is just the starting point.

We build every site with semantic HTML and structured data baked in (and yes, most agencies claim they do this too, but check their Lighthouse scores and you’ll see the difference). This makes your content easy for search engines and AI models to read, understand, and reference. It’s the foundation of solid SEO and it’s something most agencies skip entirely. We don’t.

For businesses that need more than a marketing site, we build full-stack web applications with dynamic backends and AI-powered features. Intelligent search. Personalised content. Conversational interfaces. We pick the right stack for each project, whether that’s Hugo for a brochure site, Next.js for a web application, or a custom solution for something unique.

What We Build

We handle four main types of web projects.

Marketing sites. Fast, beautiful websites for businesses that need to attract and convert visitors. Perfect for professional services, consultancies, and growing companies.

Web applications. Custom platforms with user accounts, dashboards, real-time data, and complex workflows. Built for scale from day one.

E-commerce. Headless commerce setups that combine fast storefronts with powerful backend systems. No Shopify template limitations.

Client portals. Secure, login-protected areas where your customers can access documents, track projects, or manage their accounts.

Our Development Process

Every project follows five clear steps. No mystery, no scope creep.

1. Discovery and strategy. We learn your business, your audience, and your goals. We audit your current site’s performance and map out the content architecture. This takes about a week.

2. Design. We create high-fidelity designs in Figma. You’ll see exactly what your site will look like on desktop, tablet, and mobile before we write a single line of code. Most projects need two rounds of revisions.

3. Development. We build your site with Hugo and deploy it to a global CDN. We integrate your headless CMS, set up forms, analytics, and any AI features. Development typically runs 3 to 6 weeks depending on complexity.

4. Testing and optimisation. We test across 20+ browser and device combinations. We run Lighthouse audits, check accessibility compliance, and validate all structured data. Nothing launches until it scores above 90 across the board.

5. Launch and handover. We handle DNS, SSL, redirects, and search console setup. You get full documentation and a training session so your team can manage content confidently.

Results and Performance

Numbers don’t lie. Here’s what our clients’ sites consistently achieve.

Average page load time sits at 0.8 seconds. That’s roughly 5x faster than the average Australian business website. Remember that 53% abandonment rate from earlier? Our clients don’t have that problem. Our Lighthouse performance scores average 97 out of 100. For Core Web Vitals, we target a Largest Contentful Paint under 1.2 seconds, Cumulative Layout Shift below 0.05, and Interaction to Next Paint under 100ms.

What does that translate to in business terms? Our clients typically see a 35-50% reduction in bounce rates after migrating from WordPress. Organic traffic increases of 20-40% within the first three months are common, driven purely by performance improvements and better structured data. While results vary by industry, these improvements appear consistently across our client base.

Can a faster website really make that much difference? Every piece of data says yes.

How long does it take to build a website?

A standard marketing site takes 4 to 6 weeks from kickoff to launch. Web applications typically run 8 to 14 weeks. The biggest variable is content. If you've got your copy and images ready, we can move fast.
