In the age of 5G and fibre broadband, you might think website speed doesn't matter anymore. But here's the reality: mobile users are impatient, and a slow-loading site is costing you business every single day.
Research shows that 53% of mobile users abandon a site that takes longer than 3 seconds to load. Every additional second of load time reduces conversions by 7%. For a small business, that could mean dozens of lost enquiries each month.
Why Mobile Speed Is Critical
The majority of local business searches now happen on mobile devices. Someone's boiler breaks down, they pull out their phone, search "emergency plumber near me," and they're making a decision within seconds. If your site doesn't load quickly, they've already moved on to your competitor.
"Your website might look beautiful on your desktop computer with a fast office connection. But how does it perform on a phone with patchy 4G signal? That's what your customers experience."
How to Check Your Website Speed
Google offers a free tool called PageSpeed Insights. Here's how to use it:
- Go to pagespeed.web.dev
- Enter your website URL
- Click "Analyze"
- Wait for the results (it tests both mobile and desktop)
You'll get a score out of 100 for both mobile and desktop. Generally:
- 90-100: Good
- 50-89: Needs improvement
- 0-49: Poor
Don't panic if your mobile score is lower than your desktop score—that's normal. Focus on getting mobile above 50 at minimum.
Common Speed Problems
PageSpeed Insights will list specific issues, but here are the most common culprits:
1. Unoptimised Images
That beautiful 4000x3000 pixel photo of your latest project is probably 5MB. On mobile, it should be compressed to under 100KB. Use tools like TinyPNG or Squoosh to compress images before uploading.
2. Too Many Plugins
If you're using WordPress, every plugin adds weight to your site. Deactivate and delete any you're not actively using.
3. Cheap Hosting
Budget hosting plans often mean shared servers that slow down during busy periods. For a business website, consider upgrading to a better hosting plan—it's usually only a few pounds more per month.
4. No Caching
Caching stores static versions of your pages so they don't need to be rebuilt every time someone visits. Most website platforms have caching options built in or available as plugins.
Quick Wins for Better Speed
- Compress all images before uploading
- Use modern image formats (WebP instead of JPEG where possible)
- Remove unused plugins and scripts
- Enable browser caching
- Consider a Content Delivery Network (CDN) for faster global delivery
Conclusion
Website speed isn't just a technical concern—it directly affects your bottom line. Take 10 minutes to test your site with PageSpeed Insights, and address the biggest issues it identifies. A faster site means more visitors stick around, more enquiries come through, and more customers choose you over your slower competitors.
