Wix Sites Are Faster than Ever

In the last few years, we’ve made Wix websites even faster, achieving dramatic improvements for Core Web Vitals and increasing the ratio of Wix sites with good scores by over 10x.

To make it happen, we:

• Host all our sites on a globally distributed CDN infrastructure, enabling automatic caching of all site resources, including the HTML.

• Optimize for the Largest Contentful Paint by prioritizing image and font resources, and by lazy loading elements outside the viewport

• Automatically convert Images to WebP while resizing and cropping for optimal media delivery.

• Compress all resources using Brotli to ensure faster downloads.

• Utilize code splitting and dynamic imports so sites load quickly regardless of complexity.

• Ensure all our components are built to minimize layout shifts, using proper dimensions, CSS aspect ratios and font preloads.

• Use Web Workers to reduce main-thread blocking JavaScript and minimize input delays for increased site responsiveness.
