Why Your Website Is Slow: A Web Development Fix List

What actually makes a website slow

A slow website almost always comes down to the same short list of culprits, and none of them are mysterious. Photos uploaded straight off a phone, each one weighing several megabytes. A drawer full of marketing and tracking scripts, every one of them blocking the page as it loads. Cheap shared hosting that buckles the moment more than a handful of people show up at once. And pages built entirely in the browser, leaving visitors staring at a blank white screen while code grinds away. If your site is slow, the cause is almost certainly on that list — and for the Melbourne businesses we work with, all of it is fixable.

The image problem — your biggest, easiest win

Images are the number one cause of slow pages, and the easiest to fix. A photo straight from a modern phone can be 4000 pixels wide and several megabytes — then it gets displayed in a box a few hundred pixels across, with all that extra weight downloaded for nothing. Resize each image to the size it is actually shown, save it in a modern format, and a page can shed most of its weight without losing a shred of quality. It is the single highest-return half-hour in web performance.

Core Web Vitals, in plain terms

Google measures real-world speed with a set of signals called Core Web Vitals, and uses them as a ranking factor. Stripped of the jargon, they ask three things: how quickly does the main content show up, how soon can someone actually interact, and how much does the layout jump around while loading. A page that scores badly costs you twice over — lower in search, and abandoned by visitors who gave up before it was usable.

• Compress and correctly size every image before it ships. A hero photo does not need to be 4000 pixels wide.
• Strip out tracking and widget scripts you are not actively using.
• Reserve space for images and embeds so the page does not lurch as things load.
• Choose hosting that matches your traffic, not whatever was cheapest on signup day.

The script drawer

Open the back of a typical marketing site and you will find a drawer of scripts nobody remembers adding: an old chat widget, two analytics tools doing the same job, a tracking pixel from a campaign that ended last year. Each one loads on every visit and each one slows the page. The fix is unglamorous and effective: audit the list, keep what earns its place, and delete the rest. Most sites can lose a third of their scripts and miss none of them.

Hosting you quietly outgrew

The cheapest shared hosting plan made sense on day one, when nobody had heard of you. It makes a lot less sense once a campaign lands and a few hundred people arrive at once and the whole site crawls. Hosting is not the place to chase the lowest price — it is the foundation everything else sits on. Matching your hosting to your real traffic is often the difference between a site that stays quick under load and one that falls over at the worst possible moment.

The blank-screen problem

Some sites are built so that the visitor's own browser has to assemble the whole page before anything appears. On a fast laptop you never notice. On an older phone on patchy data — which is how a lot of your customers actually arrive — it means staring at a blank white screen while the work happens. The fix is to send a page that is already built, so content appears immediately and the clever parts load after. First paint should be fast for everyone, not just for people on the latest hardware.

How we approach web development in Melbourne

Whether a site runs on WordPress, Shopify, Webflow, or a fully custom build, the speed work is the same discipline: optimise the images, cut the dead weight, cache hard, and host it properly. We build and maintain sites this way from day one, so the speed does not quietly rot six months after launch. The full scope is on our Web Development page.
