How to improve wix website speed

Wix sites typically suffer from bloated code and heavy asset loading, which you can address through several targeted optimizations. Start by auditing your site with Google PageSpeed Insights and GTmetrix to identify specific bottlenecks. The most impactful changes involve image optimization—Wix compresses images, but you should still deliver properly sized assets. Use an external tool like TinyPNG or ImageOptim before uploading, and consider serving WebP formats where possible. Remove unused Wix apps and widgets from your pages, as each one loads additional JavaScript that slows rendering. Go into your site settings and disable any apps you're not actively using; even inactive apps can impact performance. If you're using third-party integrations or custom code, audit these ruthlessly—tracking pixels, chat widgets, and form builders are common culprits that inject heavy JavaScript into every page load.

Implement lazy loading for below-the-fold images through Wix's built-in settings or custom code if needed. Defer non-critical JavaScript by placing custom code toward the end of your pages rather than in the header. If your client is running a Wix business plan or higher, you can access some additional performance settings in the advanced SEO tab. Remove autoplay videos or convert them to static images with a play button overlay—video auto-loading is one of the biggest speed killers on Wix sites. For fonts, stick to Wix's default fonts rather than loading multiple custom typefaces; each additional font file adds HTTP requests and load time.

Consider upgrading your client to a business plan if they're on a basic account, as premium tiers have better server infrastructure. If performance remains problematic despite these changes, evaluate whether Wix is the right platform for this client—highly optimization-dependent sites sometimes need a custom WordPress or Headless setup. For most small to medium business sites, these Wix-specific optimizations should push mobile PageSpeed scores into the 70-80 range, which is acceptable for most industries. Document the before and after metrics to show clients the impact of your work, and revisit performance quarterly as Wix rolls out platform updates that sometimes affect speed.
