For years, there’s been a myth floating around in the Wix community: "You can’t optimize a Wix site for mobile speed." People ache and moan about their Google PageSpeed scores stuck in the 50-60 range, claiming that Wix sites are inherently slow on mobile and that nothing can be done about it.
This is 100% false.
Not only is it possible to get a Wix mobile speed score of 80+, but with the right optimizations, you can push it to 90+, without switching platforms, sacrificing design, or rewriting your entire website.
Why Does Wix Mobile Speed Get a Bad Rap?
Before we fix the problem, let’s break down why this myth exists in the first place.
1. Wix Uses a Drag-and-Drop Editor
Wix’s flexibility allows users to create stunning designs without code, but this convenience comes with extra JavaScript overhead. Unlike platforms like WordPress, which allow direct file optimization, Wix manages its backend, limiting some speed tweaks.
2. Poor Optimization Practices Are Common
Many Wix users unknowingly overload their sites with unoptimized images, excessive animations, unnecessary apps, and bloated fonts—all of which slow down mobile performance.
3. Misinterpretation of PageSpeed Insights Scores
Probably the greatest reason of all. A 50-60 mobile score isn’t the same as a slow website. Google PageSpeed Insights provides lab-based estimates, not real-world speed. Many Wix sites load quickly for actual users, but Google penalizes factors like unused JavaScript and render-blocking elements, even if they don’t significantly impact UX. While I can agree with the scores I see based on the current optimization most of the time, it still doesn't mean the site is actually slow for other users.
The Truth: How to Get a 95+ Mobile Speed Score on Wix
Yes, it’s absolutely possible to get a Wix mobile speed score of 80-90+. Here’s how to do it.
1. Optimize Images the Right Way
One of the biggest culprits of slow Wix mobile speed are large image files.
✅ Use WebP format – This next-gen format loads faster than PNG/JPEG.
✅ Compress images before uploading (TinyPNG, Squoosh, or Wix’s built-in optimizer).
✅ Resize images to fit their container (No 3000px-wide images in a 300px box!).
✅ Use Wix’s "Adjust Image Quality" feature to serve the best format automatically.
3. Use Fewer Wix Apps (or Replace Them with Code)
Every app you install loads additional JavaScript, slowing down mobile speed.
✅ Remove unused or redundant apps (especially if they aren’t essential).
✅ Replace Wix Apps with direct embeds when possible (e.g., use Google Maps iframe instead of a Wix Maps app).
✅ Some apps can be replaced with a simple HTML embed or native Wix features.
🔍 Pro Tip: Test each app’s impact on PageSpeed Insights before keeping it.

It's available on the Wix Marketplace with a 14-day free trial. You can test your site and view your updated scores for free within literal minutes! I first tested Website Speedy on a client’s site back in December and was shocked to see their mobile score jump by 37 points in less than a minute. And it brought their desktop scores to a 98! With additional accessibility and code optimizations the mobile score was eventually brought up to an 89!
