Why Fast Websites Make More Money (And How to Speed Yours Up)

By Quentin | QWeb Studio | April 2026  ·  6 min read

Your website might look great. It might have excellent copy and beautiful photos. But if it takes more than three seconds to load on a mobile phone, a significant portion of your visitors are leaving before they ever see it. And here's the harder truth: they're not coming back.

Website speed isn't a technical nicety. It's a direct business metric — one that affects your Google ranking, your customer experience, and your bottom line.

Speed Affects Your Google Ranking

Google uses page speed as a direct ranking factor — especially on mobile. Their Core Web Vitals system measures real-world load performance, and sites that perform well are rewarded with higher rankings. Sites that perform poorly are pushed down.

This creates a compounding problem for slow websites: not only do visitors who arrive leave more quickly, but fewer visitors arrive in the first place because Google is already deprioritising the slow site in search results. You're losing customers at both ends.

For local businesses competing in Brisbane or Toowoomba, where you might be fighting for position 1–3 against several competitors, a speed advantage can be the deciding factor in who gets found first.

How to Check Your Website's Speed

Google makes this easy. Go to pagespeed.web.dev, enter your URL, and run the test. Make sure you check the Mobile tab — that's the score Google cares about most.

You'll get a score from 0–100. Here's how to interpret it:

• 90–100 — Excellent. You're in good shape.
• 70–89 — Needs improvement, but manageable.
• 50–69 — Poor. This is likely costing you rankings and customers.
• Below 50 — Critical. Fix this urgently.

5 Things That Are Slowing Your Website Down

1. Unoptimised Images

This is the single most common cause of slow websites. Photos taken on a modern phone or camera are often 4–10MB each. A page with 8 of these images is loading 80MB of data — which takes forever on mobile. Images should be compressed and served in modern formats like WebP, and ideally resized to the actual dimensions they're displayed at on screen. A hero image on mobile doesn't need to be 4000 pixels wide.

2. Too Many Plugins (WordPress Sites)

WordPress sites often accumulate plugins over time — for SEO, security, backups, forms, galleries, sliders, caching, and more. Each plugin adds code that needs to load. Twenty plugins means twenty extra scripts and stylesheets loading on every page visit. Many of these are running code even when they're not actively doing anything visible on the page.

3. Cheap Shared Hosting

The $5/month hosting plan is appealing, but it comes with a serious cost: slow server response times. Your website lives on a server, and if that server is shared with thousands of other websites and under-resourced, every page request takes longer to process. Server response time (TTFB — Time to First Byte) is the foundation of page speed, and cheap hosting reliably makes it poor.

4. Bloated Themes and Old Code

Many WordPress themes — especially popular commercial ones — are built to be flexible and feature-rich for anyone. They load fonts, CSS files, JavaScript files, and layout systems for features you'll never use. All of that code loads on every page visit, adding weight and latency. Similarly, sites that haven't been properly maintained often have outdated code that modern browsers have to work harder to interpret.

5. No Browser Caching or Content Delivery Network (CDN)

Caching means storing a version of your website on the visitor's browser so they don't have to download everything again on their next visit. A CDN serves your website from servers physically located close to your visitors. Without either of these, every visit to your site requires fetching everything fresh from a single server, which adds time. Both are relatively simple to implement and can dramatically improve load speeds for repeat visitors.

Why Custom-Coded Sites Are Faster Than WordPress

This is one of the reasons we build custom-coded websites at QWeb Studio rather than using WordPress or website builders. A custom-coded site contains exactly the code it needs — nothing more. There are no plugins, no bloated themes, no framework overhead. The result is a leaner, faster website that consistently scores higher on PageSpeed tests.

A typical WordPress site with a popular theme and ten plugins might score 45–60 on mobile PageSpeed. A well-built custom-coded site for the same business routinely scores 90+. That difference translates directly to better Google rankings and more customers who actually stay on the page long enough to contact you.

Quick Wins If You're on WordPress

If you're already on WordPress and can't rebuild right now, here are three things you can do immediately to improve your score:

1. Compress your images — Install a plugin like ShortPixel or Smush to automatically compress images. It's free and makes an immediate difference.
2. Add a caching plugin — WP Rocket is the best (paid), W3 Total Cache is free and effective. Enable it and it'll serve cached versions of your pages instead of generating them from scratch on every visit.
3. Deactivate and delete unused plugins — Go through your plugins list and remove anything you're not actively using. Be ruthless — every plugin you remove makes the site a little lighter.
