Your Website Is Slow — And It's Costing You Customers

Here's a stat that should concern you: 53% of mobile visitors leave a website that takes longer than 3 seconds to load. That's not a conversion optimisation detail — that's more than half your potential customers gone before they even see what you offer.

And it gets worse. Since 2021, Google has used page speed as a direct ranking factor. If your site is slow, you're not just losing visitors who arrive — you're also ranking lower, so fewer people arrive in the first place.

How to Check Your Score (10 Seconds)

Google provides a free tool called PageSpeed Insights. You type in your URL, and it gives you a score from 0 to 100 for both mobile and desktop.

  • 90–100: Excellent. You're in the top tier.
  • 50–89: Needs improvement. You're leaving performance on the table.
  • 0–49: Poor. This is actively hurting your business.

We built a free audit tool on our site that runs this check instantly and shows you exactly what's wrong. No email required, no sales pitch hidden behind it.

What's Actually Slowing Your Site Down

After auditing hundreds of small business websites, the same problems come up repeatedly:

1. Massive Images

The single biggest culprit. A hero image saved as a 4MB JPEG when it could be a 150KB WebP. Many sites we audit have 10–20MB of images loading on the homepage alone. Modern formats (WebP, AVIF) and proper sizing can cut this by 90%.

2. Too Many Third-Party Scripts

Google Analytics, Facebook Pixel, chat widgets, cookie banners, font libraries, animation libraries — each one adds network requests and JavaScript that blocks rendering. Most small business sites load 15–30 external scripts. You probably need 3–5.

3. No Caching or Compression

Basic server configuration that many hosting providers don't set up properly. Enabling gzip/brotli compression and proper cache headers can cut load times by 40–60% with zero visual changes.

4. Render-Blocking CSS and JavaScript

If your CSS and JS files load before any content appears, visitors see a blank white screen for 2–4 seconds. Critical CSS inlining and async script loading solve this.

Why This Matters for Your Business

This isn't a technical vanity metric. The numbers are clear:

  • A 1-second delay in page load reduces conversions by 7%
  • Pages that load in 2 seconds have a 9% bounce rate. At 5 seconds, it's 38%
  • Google ranks fast sites higher in local search results — critical for service businesses
  • Slow sites damage trust. If your website is sluggish, visitors assume your service will be too

What Good Looks Like

Every site we build at Studio 72 targets a 90+ PageSpeed score on both mobile and desktop. We achieve this through:

  • Next.js with automatic image optimisation and code splitting
  • Modern image formats served at the right size for each device
  • Minimal JavaScript — we don't load what isn't needed
  • Edge deployment on Vercel's global CDN (content served from the closest server)
  • Font optimisation with display swap and preloading

The result: sites that load in under 1.5 seconds on mobile, even on 3G connections.

Quick Wins You Can Do Today

Even without rebuilding your site, these three changes can make a noticeable difference:

  1. Compress your images. Use Squoosh (free, by Google) to convert images to WebP and resize them to the actual display size.
  2. Remove scripts you don't use. That chat widget with zero conversations? That social share bar nobody clicks? Remove them.
  3. Enable caching. Ask your hosting provider to enable browser caching and gzip compression if they haven't already.
