How we build websites that fly
Design gets the credit, but development is where a website is won or lost. Here's how we turn a beautiful design into a fast, solid, search-friendly site — by hand, line by line.
Our development principles
No bloated page builders. No template spaghetti. Every WillowTree site is hand-coded on modern foundations, which is why they load in under a second and rank the way they do.
Many small business websites are built on drag-and-drop builders or heavy themes, loaded with code they never use. That extra weight slows pages down, frustrates visitors on mobile and holds back your Google rankings. Our custom web development starts from a clean slate, so your site includes only what it needs.
The result is a fast, secure, mobile-friendly website that's easy for search engines to read, accessible to every visitor and simple to grow as your business does. Here are the principles behind every site we build.

Speed first
Sub-second loads aren't luck — they're the result of lean, hand-written code with nothing along for the ride that your site doesn't need. Faster pages keep visitors around longer and turn more of them into enquiries.
Every screen, flawless
Phone, tablet, laptop, widescreen — your site adapts to all of them. Most of your visitors are on a phone; we build like it. Menus, buttons and forms are designed to be easy to tap and quick to use on any screen.
Google-friendly by design
Clean, semantic code that search engines can read effortlessly — structure, speed and metadata all working for your ranking. Structured data helps Google show richer results for your business.
Our build process
Once a design is approved, here's exactly what happens between "looks great" and "we're live".
Plan the foundations
Before any code, we map the site's structure: pages, sections, and how they connect. A clear plan up front means clean code later — and a site that's easy to grow when your business does.
Hand-code the build
We write the HTML, CSS and JavaScript ourselves — no drag-and-drop builders, no heavyweight themes. That's why our sites carry none of the invisible baggage that slows most websites down.
Make it responsive
Every layout is built to flex — text, images and menus rearrange themselves gracefully from the smallest phone to the widest monitor. We test on real devices, not just a resized browser window.
Tune for speed & search
Images compressed, code minified, and every page measured against a sub-second target. On-page SEO is baked in as we build: titles, descriptions, headings, and structured markup that Google understands.
Test everything
Browsers, devices, slow connections, screen readers — we push on every corner before launch day so your visitors never find a wobble we should have caught.
Launch & keep watch
We handle the launch end to end, then stay on the tools: monitoring, updates, backups and tweaks. A website is a living thing — ours are looked after.
Web development FAQs
How long does it take to build a website?
Most small business websites take around 2 to 3 weeks from our first chat to launch. Larger sites, online shops and custom features can take longer. We'll give you a clear timeline with your quote, so you know exactly when to expect your new website.
Do you use WordPress or website builders?
No. We hand-code every website with clean HTML, CSS and JavaScript, rather than relying on page builders or heavy off-the-shelf themes. That keeps your site lean, fast and secure, without the plugins and bloat that slow many websites down.
Is a hand-coded website better than a template?
For most businesses, yes. Templates and page builders load lots of code your site never uses, which makes pages slower and harder for Google to read. A custom-coded website includes only what it needs, so it loads faster, ranks better and looks unique to your brand.
Why does website speed matter?
Visitors expect pages to load almost instantly, and many leave if a site feels slow, especially on mobile. Google also uses page speed and Core Web Vitals as ranking signals. A fast website keeps more visitors, wins more enquiries and helps you climb the search results.
Will my website work on mobile phones and tablets?
Yes. Every site we build is fully responsive, so layouts, images and menus adapt to any screen size. We test on real phones and tablets, not just a resized browser window, so your website works properly wherever your customers find you.
Will my website be accessible?
Yes. We build with accessibility in mind, using clear headings, good colour contrast, descriptive image text and support for keyboards and screen readers. An accessible website is easier for everyone to use and is also better for SEO.
Can my website grow as my business grows?
Absolutely. We plan the structure before we write any code, so adding new pages, services or features later is straightforward. With our care and maintenance plans, we can make those updates for you whenever you need them.
